CNC Centerless Grinders

Centerless grinder controls built to reduce uncertainty from legacy equipment

Q: Will a retrofit make the grinder easier for operators to use?

Yes. A retrofit can make a cylindrical grinder easier to use by giving operators a more intuitive touchscreen interface, clearer controls, and a more reliable day-to-day experience.

Q: How much downtime should I expect during a cylindrical grinder retrofit?

Downtime depends on the grinder and the scope of work. Our experts can determine this with you before the retrofit begins. Most customers with running machines see a retrofit as planned downtime that helps reduce the risk of longer, unplanned downtime later.

Q: Can MachMotion retrofit both ID and OD grinding applications?

Yes. MachMotion can support cylindrical grinder retrofit applications for ID, OD, and universal grinding, depending on the machine’s configuration and overall fit.

Q: Why upgrade an existing machine instead of buying a new one?

If the machine’s mechanics are still sound, a control retrofit can be a more cost-effective way to extend machine life. It lets you keep the proven iron while replacing the part of the machine most likely to create obsolescence, downtime risk, and support problems. The right choice depends on the machine’s mechanical condition, replacement cost, production value, and how much useful life the retrofit can help recover.

Keep a maintained centerless grinder in production with a modern control.

Signs a Retrofit May Be Needed

What we hear from shops running CNC Centerless Grinders

Dressing takes too much operator skill, time, or trial-and-error
Switching between thru-feed and in-feed is harder than it should be
Machine still grinds, but confidence in the process is gone
Control problems keep turning into tedious downtime

Benefits

What changes after the retrofit

Easy profile dressing customized with standard g-code
Simplified thru-feed and in-feed changeover
Confidence in the process is restored with operators
Supportable and modern centerless grinder control

What's Included

A production-ready package

No missing pieces, no surprises during install. Every CNC Centerless Grinder retrofit ships as a complete system.

MachMotion centerless grinder controller & pendant

Servo package sized to axis load

Electrical enclosure or panel and wiring

Dress cycle logic and wheel-wear offsets

Commissioning and lifetime remote support

Good Fit

A retrofit likely makes sense if:

OD/ID cylindrical grinders with sound mechanics
Grinders whose OEM control is discontinued but the machine is still accurate

Not a Fit

Replacement may make more sense if:

Grinders with worn ways or spindle bearings that limit accuracy at the source
Highly specialized form grinders needing OEM-specific dress kinematics we cannot match

FAQ

About CNC Centerless Grinders

What parts of the cylindrical grinder are replaced in a control retrofit?

A control retrofit replaces the grinder’s aging control system, not just the screen. This includes the front end control, controller hardware, electrical enclosure, and related electronics needed to make the machine reliable and fully supported again.
