Machine Spindle Oil Chiller
Machine Tool Cooling Units
- Process Chiller Type: Oil medium, air-cooled chiller
- Cooling Capacity: 0.3-110kW
Oil chillers are temperature control units designed to control heat of spindle systems of various machine tools such as CNC machines, grinders, boring machines, milling machines, and gantry machining centers. During continuous machining processes, spindle lubrication oil and hydraulic oil gradually increase in temperature due to friction and workload, and if heat is not properly controlled, thermal deformation can affect spindle stability and cause machining errors. When using oil chillers, the spindle oil remains at a stable temperature throughout machining, which helps the spindle to maintain accuracy and prevent expansion due to heat.

Features
- Thanks to direct-drive cooling, spindle temperature remains stable during machining, thermal expansion is reduced, and machining accuracy stays stable.
- Due to stable temperature control, spindle bearings stay protected from overheating, which helps prevent jamming issues and extends bearing life during continuous operation.
- Equipped with a full metal oil tank that works efficiently in extreme hot and cold environments, especially in places that have frequent temperature changes.
- The electrical system separates high and low voltage circuits, reduces risk during maintenance and daily operation, and improves operator safety.
