Hydraulic, Lubrication, and Chiller System Service
Hydraulic and lubrication problems shut down production fast. Low hydrostatic pressure triggers axis inhibit alarms. Seal leaks contaminate coolant. Chiller faults halt thermal stability.
MMS diagnoses and repairs these systems on-site across Kellenberger, Jones & Shipman, USACH, Hardinge, Hauser, Palmary, Supertec, Okamoto, and many other grinders.
Our approach is to find the root cause and provide a long-lasting, durable repair. If you are seeing low lube or hydrostatic pressure alarms, unexplained coolant loss, or oil leaks, call us before the problem compounds.
Common symptoms we resolve
Axis inhibit alarms on startup tied to hydrostatic pressure.
Low hydrostatic or way lube pressure warnings under load.
Visible oil leaks tracked back to seals, fittings, or pumps.
Coolant contamination from way lube or hydraulic crossover.
Chiller faults affecting thermal stability and finish.

Frequently asked questions
We have low hydrostatic pressure but no visible leak. What is it?
Common causes: a worn pump, a relief valve that has started bypassing, a degraded metering unit, or a leak inside the casting that does not present externally. We diagnose under pressure and isolate which it is.
