Okuma CNC Cooling & Lubrication Service

What Is Okuma Cooling & Lubrication Service?

Every Okuma machine depends on two fluid systems working correctly: coolant that keeps the cutting zone from overheating, and way lube that keeps ball screws and linear guides moving without excess friction. We handle both sides of keeping these systems healthy — the physical work of draining and refilling fluid, cleaning sludge out of tanks, replacing pump seals and filters, and the electronics behind them: pump control boards, level and pressure sensors, thermal circuits, and water-in-oil detection. We're a full-service shop, not an electronics-only specialist — the same team that repairs your control board can also clean your coolant tank and service your way lube pump.

When something goes wrong, the fix depends on correctly identifying the actual cause first. A "low level" alarm that won't clear can mean the tank genuinely needs fluid, or it can mean sludge is blocking the sensor orifice while the tank stays full. An oil hole motor overload alarm can mean a failed pump motor or a clogged line making it work harder than it should. We diagnose which one you're actually dealing with, then do the repair ourselves — whether that's cleaning a fouled sensor, replacing a pump seal, or repairing a control board.

We are an independent repair company. We are not an authorized Okuma dealer, distributor or service partner — we service Okuma cooling and lubrication systems, mechanical and electronic, on customer-owned equipment.

Way lube pumps in particular have a known service life — the pump types commonly used on Okuma machines run roughly 8,000 hours under normal conditions, but contaminated oil or irregular maintenance can cut that closer to 4,000 hours. The smallest lubrication jets, the ones feeding ball screw nuts, tend to clog first and are often the earliest sign of a developing problem — whether the fix turns out to be a thorough cleaning or a full pump rebuild.
