Preventive Maintenance Programs for Precision CNC Grinders
Scheduled PM is the difference between planned service and emergency downtime. MMS technicians perform preventive and predictive maintenance on Kellenberger, Studer, Okamoto, Tschudin, Jones & Shipman, Hauser, USACH and many other precision grinders.
A single emergency service call, with travel, diagnostic time, expedited parts, and lost production, typically costs more than an entire annual PM visit. PM visits also give our technicians a chance to flag wear before it turns into a breakdown.
Our PM checklists are tailored to each machine type and often go deeper than what an OEM provider would do. We replace normal PM items and provide predictive maintenance to get ahead of critical repairs so you stay in production.
Why a PM contract pays for itself in the first incident avoided
Hydraulic seals and hydrostatic pressure components do not give a warning before they fail. A scheduled inspection catches the seal that has started weeping but has not yet dropped pressure below the axis-inhibit threshold.
Linear scale signal degradation is detectable on a PM visit long before the alarm trips and the machine stops. Replacing a scale on schedule is a fraction of the cost of replacing one mid-job with parts overnighted and a technician on emergency rates.
Belt and bearing wear shows up in vibration and runout measurements taken at PM. Catching this avoids the spindle rebuild that follows.
Who this is for
Shop owners and maintenance managers running production grinders where unplanned downtime costs real money.
Operations leaders building a maintenance budget who want defensible numbers for next year.
Anyone who had at least one emergency service call this year. A PM program is almost always less expensive than the next one.

Frequently asked questions
How often should a production CNC grinder go on PM?
For grinders running multiple shifts, semi-annual PM is the right baseline. Single-shift, lower-utilization machines can usually move to annual. We tailor frequency to your actual run hours and the data we collect on the first visit.
What is the difference between MMS PM and OEM PM?
OEM PM tends to follow a fixed checklist tied to a service contract. Ours is tailored per machine and includes predictive checks: ballscrew repeatability, spindle runout, scale signal health, Profibus diagnostics. You get a written findings report, not just a checklist.
