CNC Grinder Replacement Parts

We work with you to find the right parts at a reasonable cost. With 200+ years of combined hands-on grinding experience, we source parts the same way we service machines — with the expertise to differentiate a precise match from a near one.

• OEM and quality-equivalent parts for precision CNC grinders
• Authorized reseller for Elaso and HEIDENHAIN
• Cross-reference support for discontinued and legacy parts
• Shipping across the United States, Canada, and Mexico
• Optional installation by our field technicians

Parts Categories

Measurement, Gap & Balancing Systems

Linear scales, rotary encoders, gap control, and in-process gauging — the parts that determine whether your machine holds size. Includes Elaso, Marposs, Movomatic, HEIDENHAIN, and Fanuc.

• Linear scales
• Rotary encoders
• Scale mounting hardware and signal cables
• Elaso Gap & Balancing — retrofit aging Marposs and Movomatic systems with Elaso

Electrical, Control & Servo Systems

Electronic parts for Fanuc, HEIDENHAIN, and Siemens controls.

• Servo drives and motors
• Control system PC boards
• Power supplies
• Fuses, contactors, and relays
• Cables, connectors, and wiring harnesses

Mechanical Drive

The moving parts that wear out in normal service and the high-precision components that need careful sourcing.

• Ballscrews and ballscrew bearings
• Linear guides and way covers
• Spindle bearings and bearing assemblies
• Drive belts
• Couplings and drive components
• Proximity switches and limit switches

Hydraulic, Hydrostatic & Lubrication

Parts for the fluid systems that keep hydrostatic guides, way lubrication, and tailstocks working.

• Seals, O-rings, and gaskets
• Hydraulic pistons and cylinders
• Way lube metering units, hydrostatic filters, and way lube filters
• Pressure switches and regulators
• Hoses and fittings
• Hydraulic and lubrication pumps

Coolant & Chiller

Parts for coolant delivery, thermal stability, and separation systems.

• Coolant pumps and motors
• Chiller components and fluid
• Replacement chiller systems
• Coolant separators and filtration
• Nozzles, manifolds, and delivery hardware

Wear & Consumable Items

The items that come off a grinder during PM and that you want on the shelf before they fail.

• Wipers and seals
• Belts and pulleys
• Filters (all types)
• Batteries
• Lamps, indicators, and operator-panel consumables

What We Need to Quote a Part

• Machine make and model
• Serial number if available (critical for older machines with running changes)
• Part number if known, or a description of the failed component
• Alarm codes or symptoms if you are diagnosing
• Urgency — machine down, scheduled PM, or stock replenishment

Need Installation, Too?

MMS field technicians install the parts we supply. That means one vendor, one invoice, and technicians who know the part and the machine. Ask us to bundle the part and the install into one quote, or see our CNC Grinding Machine Repair & Service page for on-site service.
