When a machine goes down in the Midway, Energy Park, or anywhere else in St. Paul, you don’t want a repair company treating Minnesota like a distant travel market. Allied MachineX has technicians based in Minneapolis, and for emergency hard downs we can usually have a tech onsite the same day, anywhere in the Twin Cities. Our 24/7 emergency line means you reach a real technician at 2 AM, not a call center.
We repair, rebuild, maintain, calibrate, and sell industrial production equipment: CNC machining centers and lathes, press brakes, punch presses, fiber lasers, plasma cutters, band saws, grinders, routers, EDMs, waterjets, and more. Our technicians are backed by mechanical engineering expertise, which means correct diagnosis and straight advice instead of parts-swapping. We work on Mazak, Haas, Hurco, Okuma, Doosan, DMG Mori, Makino, Fadal, Cincinnati, Chicago Dreis & Krump, LVD, Wysong, Ermaksan, HACO, SMART, Amada, Trumpf, Bystronic, Hyd-Mech, Kalamazoo, DoAll, and plenty more.
Call 844-763-1748 when your machine is down, losing accuracy, throwing alarms, or just not running the way it should.
Machine Down in St. Paul? Here's What Happens When You Call
A lot of repair companies take your address and show up cold. Here is our process, so you know what you’re getting before you ever dial:
- You describe the symptom to a technician, not a call center. Alarm numbers, when it happens, what changed. The more you can tell us, the faster we get there.
- We start remote diagnostics before the truck rolls. For many control and electrical faults, our technicians begin troubleshooting over the phone, often cutting on-site diagnosis time significantly.
- We troubleshoot the machine as a complete system: electrical, mechanical, hydraulic, pneumatic, and control, with mechanical engineering expertise behind the diagnosis. A servo alarm doesn’t automatically mean a bad servo motor, and a machine that won’t cycle might have a PLC, safety circuit, pneumatic, hydraulic, or sensor issue. We find the actual failure before recommending parts, and that alone has saved shops thousands in components they never needed.
- You get a straight answer on repair, rebuild, or replace. We do both service and machine sales, so we have no incentive to push one answer. Sometimes it’s a $400 sensor. Sometimes it’s time.
- The work gets verified before we call it done. NIST-traceable calibration and post-repair checks come standard, not as an upsell.
Pro tip: Don’t clear a recurring servo alarm and keep running. Write down the full alarm number and when it happens. That one habit can cut diagnostic time dramatically when the tech arrives.
CNC Machine, Mill and Lathe Repair in St. Paul
We provide CNC machine repair for machine shops, fabricators and production plants across St. Paul and Ramsey County. That covers machining centers and CNC lathes from Mazak, Haas, Hurco, Okuma, Doosan, DMG Mori, Mori Seiki, Makino, Fadal, Kitamura, Hardinge and SMART, manual mills and lathes from Bridgeport, Sharp, Clausing, LeBlond and Monarch, and control diagnostics on Fanuc, Siemens, Mitsubishi, Heidenhain and Fagor controls.
CNC mill repair and CNC lathe repair are the calls we take most: vertical and horizontal machining centers, turning centers, and the manual Bridgeports still earning their keep in tool rooms across the city.
Common calls we take: machine won’t start or home, axis won’t move or loses position, servo alarms and following errors, encoder faults, spindle won’t start or overheats, tool changer stuck, turret won’t index, lost parameters, blank control screen, machines that keep tripping a safety circuit, and intermittent electrical gremlins nobody can pin down. The symptom is usually just the beginning of the diagnosis, and that’s fine. Bring us the symptom.
One more thing worth knowing: our team brings 15+ years of hands-on time with mills, lathes, grinders, saws, and press brakes, and if your problem lives in the control, we also service HMI controllers like Delem and Cybelec that many shops get stuck waiting on OEM support for. And we service wood and metal CNC routers, the kind running cabinet, millwork and sign shops, from SCM and Biesse nested routers to ShopBot and AXYZ machines.
Servo Motor Repair and Rebuild
Servo problems stop machines that are otherwise mechanically sound. We troubleshoot servo motors, drives, amplifiers, encoders and feedback systems from Fanuc, Siemens, Yaskawa, Mitsubishi, Allen-Bradley, Indramat, Glentek, Baldor and Kollmorgen, plus the wiring and machine conditions around the fault. When a motor needs more than field repair, we handle rebuild and replacement sourcing, and we’ll tell you straight whether repair, rebuild or replace makes financial sense for that machine.
Press Brake Repair in St. Paul
Fabrication shops across the Twin Cities call us for press brake repair on Cincinnati, Chicago Dreis & Krump, Amada, Accurpress, LVD, Wysong, Durma, Baykal, Pacific, Ermaksan, HACO and Trumpf equipment. Service covers hydraulic troubleshooting, backgauge repair, Y1/Y2 and ram positioning problems, crowning issues, encoder and servo faults, control problems, safety systems and full calibration.
Backgauge losing position? The cause can live in the servo, drive, encoder, ballscrew, bearings, sensors, wiring or parameters. We diagnose the system before recommending parts.
Pro tip: Inconsistent bends aren’t always tooling. Ram parallelism, hydraulics, crowning, backgauge position and material variation all contribute. Check the machine before you blame the punch and die.
Punch Press, Ironworker and Shear Repair in St. Paul
Stamping work runs on mechanical presses from Minster, Bliss, Niagara and Verson, and turret punches from Amada, Trumpf, Strippit and Murata Wiedemann. We handle clutch and brake assemblies, gib adjustments, counterbalance systems, feed alignment, turret indexing and the control and safety systems around them.
Ironworkers from Scotchman, Piranha and Edwards get the same treatment: punch and die alignment, notching stations, shear blades, hydraulic circuits and safety guards.
Shear work covers Cincinnati, Wysong, Accurpress and Amada machines, and it is more than blade changes. Blade gap, rake angle, hold-down pressure and blade condition all decide cut quality. We set gap and rake for the material, service the hold-downs, and tell you when a blade flip beats a blade change.
We also repair plate rolls and tube benders: cones, leaks and out-of-round on rolls, and bend arm, pressure die and clamp die wear on tube benders.
Fiber Laser and Plasma Cutting Machine Repair
We service laser and plasma cutting machines for St. Paul fab shops running Trumpf, Bystronic, Mazak, Mitsubishi, Prima Power, LVD, Amada, Ermaksan and Hypertherm equipment. Fiber laser work includes cutting head service and rebuilds, protective window and lens replacement, nozzle alignment, height sensing problems, source troubleshooting, chiller and cooling issues, and chasing down power loss or poor edge quality. Plasma service on Hypertherm, Esab, Messer and Koike systems covers arc stability, torch height control, gas delivery and consumable life.
Common laser calls: won’t fire, losing power, heavy dross, inconsistent piercing, windows contaminating too fast, head crash recovery, cooling faults.
Band Saw and Grinder Repair
Industrial band saw repair covers Hyd-Mech, Kalamazoo, DoAll, Marvel, HE&M, Behringer, Cosen and W.F. Wells saws: blade guides, feed systems, hydraulic vises, coolant systems and the head-won’t-drop, blade-won’t-track problems that stop a saw line cold. Surface and tool grinder repair covers Okamoto, Chevalier, Brown & Sharpe, Harig, Blanchard, Mitsui and Studer machines: spindle bearings, magnetic chucks, wheel head alignment and table parallelism for tight-tolerance work.
EDM and Waterjet Machine Repair
Wire EDM machines from Sodick, Mitsubishi and Makino cut with the wire, the power supply and the dielectric working together, so trouble shows up as wire breaks, taper or corner errors, poor surface finish and brass wire feeding issues. We troubleshoot wire transport, guides and power settings, dielectric systems and flushing, and machine geometry, not just the symptom.
Waterjets from Flow and Omax live or die by the pump. Intensifier pumps, high-pressure seals, orifices and mixing tubes, abrasive feed and metering, catch tank condition and edge taper all affect cut quality and operating cost. We diagnose the cutting head and the pump as one system, because a worn orifice and a failing seal can look identical at the workpiece.
PLC and Industrial Electrical Troubleshooting
A control screen lighting up doesn’t mean every control voltage, safety circuit and I/O condition is present. We troubleshoot Allen-Bradley, Siemens, Mitsubishi, Omron, Modicon and AutomationDirect PLCs, machine I/O, 24-volt supplies, contactors, relays, VFDs, safety relays, light curtains, E-stop circuits, proximity sensors, wiring faults and ground faults. We diagnose the whole circuit instead of assuming the visible component is the failed one.
We also service and integrate machine safety systems: light curtains, barriers, and advanced solutions from Lazersafe, Sick and Pilz, so your operation stays protected and compliant, not just running.
Hydraulic and Pneumatic Machine Repair
Hydraulics run press brakes, saws, clamping systems and plenty of older CNC equipment. We troubleshoot cylinders, pumps, valves, proportional valves, pressure problems, leaks, overheating and ram movement issues. On the pneumatic side: cylinders that won’t extend or retract, solenoids that fire while the actuator sits still, machines with air that won’t cycle, clamps that won’t engage or release, and low-pressure faults.
When a cylinder stops moving, the cylinder often isn’t the failure. Pressure, flow controls, solenoids, sensors, PLC outputs and safety conditions can all block movement. We check the system before you buy the part.
Spindle, Ballscrew and Machine Rebuilds
Spindle trouble shows up as runout, bearing noise, vibration, overheating, poor surface finish or tool retention problems. Depending on condition, the answer is field repair, removal and rebuild, or replacement, and we support all three through our machine rebuild services. Ballscrew and positioning work covers wear and backlash measurement, support bearings, couplings, alignment and lost motion, because a machine losing tolerance isn’t always a control problem.
Every rebuild leaves with documented, NIST-traceable calibration, so you have proof of accuracy for your own quality system, not just our word for it.
Pro tip: Spindle problems don’t improve on their own. If an operator says the spindle sounds different, take it seriously. A change in noise, heat or finish is often the cheap warning before the expensive failure.
Repair, Rebuild, Upgrade or Replace?
Not every machine problem has the same answer. Sometimes the right move is a repair. Sometimes a spindle or servo should be rebuilt. Sometimes an aging control deserves an upgrade. And eventually, putting more money into an outdated machine stops making sense. Our mechanical engineers weigh the machine’s condition against the economics, and because Allied MachineX does both service and machine sales, we can talk through the whole lifecycle honestly instead of pushing one answer.
New Machines, Press Brake Sales and Refurbished Equipment
When replacement wins, we help St. Paul shops source it. We’re proud to offer HACO press brakes, shears and fiber laser systems through our new machine sales. We can also assist with a number of other popular brands, so call and ask our sales team what’s available. And our refurbished machines give shops a way to add capacity on a budget. We help you match tonnage, bed length, material mix, controls and tooling to the work your shop actually runs, then handle installation, leveling, calibration and startup so the machine produces instead of just occupying floor space.
Every refurbished machine we source includes a free tune-up you can use within two years of purchase, so the machine stays production-ready long after it’s installed.
Pro tip: Don’t buy a press brake based only on today’s largest part. Size it for the material mix and volumes you expect to run three to five years out. Too little machine forces another capital purchase early, and way too much machine ties up money for years.
Preventive Maintenance Programs
Emergency repairs matter, but preventing the emergency is cheaper. Our preventive maintenance programs cover lubrication, hydraulics, pneumatics, electrical cabinets, filters, belts, safety systems, spindle and axis condition, backlash checks and leveling. A good PM visit hands management a priority list: what needs repair now, what to schedule soon, what’s wearing but serviceable, and what’s worth upgrading later. That beats reacting to every failure as it happens.
PM visits can include NIST-traceable calibration: the documented, auditable kind your quality manager actually wants in the file.
Outsourced Maintenance for Facilities That Can't Staff It
A lot of facilities, especially the big ones, can’t hire and keep the maintenance talent their equipment needs. Machine repair techs, controls people and millwrights are hard to find, expensive to keep, and one resignation can leave a whole plant exposed. That’s why more Minnesota facilities broker their equipment maintenance out instead of fighting to staff it.
Allied MachineX can run as your outside maintenance department: scheduled PM visits on your equipment list, priority response when something breaks, and mechanical engineers behind every tech for the repair-or-replace calls your team shouldn’t have to guess at. You get the coverage of a full maintenance staff without the headcount, the recruiting or the payroll. Call 844-763-1748 and we’ll scope a program around what’s actually on your floor.
You'll Talk to Owners, Not a Script
Allied MachineX is owned and operated by Tim, Josh, and Kent, three people with more than 15 years of combined shop-floor experience who answer their own phones. When you call about a machine down in St. Paul, you’re talking to someone who has personally worked on Haas mills, Mazak lathes, and Amada press brakes.
“Manufacturing doesn’t sleep, and neither do we.” Tim, co-owner
“We’re not just fixing machines, we’re keeping people employed and production lines running.” Josh, co-owner
“Most shops don’t need a new machine, they need someone to find the actual failure. Our job is to tell you which is which, even when the answer is a $400 sensor. That’s what we’d want someone to tell us.” Kent, co-owner
Serving St. Paul, the Twin Cities and All of Minnesota
Our St. Paul coverage runs through the city’s real industrial ground: the Midway and West Midway corridors, including Energy Park, plus Beacon Bluff on the East Side, Riverview along the river, River Bend Business Park, and the Great Northern Business Center in the North End. If your shop sits in one of these parks, you’re on our route, not at the end of it. The surrounding suburbs get the same coverage: Roseville, Maplewood, Woodbury, Eagan, Oakdale, Shoreview, Arden Hills, Vadnais Heights, and White Bear Lake. We also serve Minneapolis and the west metro, Rochester and Winona in southern Minnesota, and manufacturers statewide. For emergency hard downs across Minnesota, our 24/7 line is the fastest way to reach a technician, and our Minneapolis-based techs put the Twin Cities within same-day reach.
Frequently Asked Questions
Do you provide CNC machine repair in St. Paul?
Yes. We provide CNC and industrial machine troubleshooting, repair, rebuilds, preventive maintenance, and machine sales for manufacturers in St. Paul and throughout the Twin Cities, with technicians based in Minneapolis.
How fast can you get to St. Paul?
Our technicians are based in Minneapolis, so the Twin Cities are home turf. For emergency hard downs we can usually respond same day. For scheduled work, you get a real arrival window, not a four-hour block.
What brands do you work on?
Mazak, Haas, Hurco, Okuma, Doosan, DMG Mori, Makino, Fadal, Kitamura, Hardinge, SMART, Bridgeport, Cincinnati, Chicago Dreis & Krump, Amada, Accurpress, LVD, Wysong, Durma, Ermaksan, HACO, Trumpf, Bystronic, Hypertherm, Minster, Bliss, Niagara, Verson, Murata Wiedemann, Scotchman, Piranha, Edwards, Hyd-Mech, Kalamazoo, DoAll, Marvel, Behringer, Okamoto, and Blanchard among others, with control and servo work on Fanuc, Siemens, Mitsubishi, Heidenhain, Fagor, Yaskawa, and Allen-Bradley, HMI controllers like Delem and Cybelec, wood and metal CNC routers, wire EDM machines from Sodick, Mitsubishi and Makino, and waterjets from Flow and Omax. If your brand isn’t listed, call. It probably just didn’t fit on the page.
Can you troubleshoot a machine if we don't know what's wrong?
Yes. Most service calls start with a symptom, not a known failed part. Diagnosing the mechanical, electrical, control, hydraulic, or pneumatic cause is the job. We can also start remote diagnostics before arriving.
How much does CNC machine repair cost?
It depends on the failure, but here is how we keep it honest: you approve the diagnosis before parts get ordered, and you get a repair-versus-replace recommendation backed by mechanical engineering expertise, not a sales quota. Call 844-763-1748 for current diagnostic rates. Scheduled maintenance programs can be scoped to a monthly budget.
Do you repair punch presses, shears, ironworkers and CNC routers?
Yes. We service mechanical stamping and punch presses from Minster, Bliss, Niagara and Verson, turret punches from Amada, Trumpf, Strippit and Murata Wiedemann, ironworkers from Scotchman, Piranha and Edwards, and shears from Cincinnati, Wysong, Accurpress and Amada, along with plate rolls, tube benders and wood and metal CNC routers. If it bends, cuts, stamps or routs in a shop, we can likely service it.
Do you repair EDM machines and waterjets?
Yes. We service wire EDM machines from Sodick, Mitsubishi and Makino, and waterjet systems from Flow and Omax. That covers wire transport and power supply problems, dielectric and flushing issues, intensifier pumps, high-pressure seals, orifices, abrasive feed and edge quality.
Do your repairs come with a warranty?
New machines and most replacement parts carry manufacturer warranties. On repair work, we put warranty terms in writing before the job starts. And your team signs off every repair as complete and tested before our technician leaves your floor, so everyone agrees on the condition of the machine when it changes hands.
Can you help us buy a new press brake?
Yes. We offer HACO press brakes, shears and fiber lasers, and we can source other popular brands too. Call and ask our sales team what’s available. We’ll help you evaluate tonnage, bending length, materials, controls, and tooling before you commit.
Should we repair our old machine or replace it?
We’ll evaluate the failure, the machine’s overall condition, parts availability, and your production needs, then lay out the repair, rebuild, upgrade, and replacement options honestly. Sometimes the answer is a $400 sensor. Sometimes it isn’t.
Can you handle our facility's maintenance so we don't have to staff it?
Yes. Many facilities can’t hire or keep the right maintenance people, so they contract it out. We take that on with scheduled PM, emergency coverage, and engineering support, sized to the equipment on your floor.
