GREE MACHINE OIL COOLER HIGH RELIABILITY CNC LINKAGE inner tube, while the turbulence in the spiral tube inhibits the deposition of dirt on the surface, making the heat exchanger more efficient, compact and scale resistant. Connect the signal line to the machine through the alarm interface. Oil Cooler can send failure signal to the machine through signal line in case of fault. Reserve a remote switch interface for users to realize remote on-off control. Fault/ Abnormal Temp Remote switch HIGH PRECISION HIGH ADAPTABILITY Gree Oil Cooler adopts inverter compressor and electronic expansion valve, and accurately controls oil temperature accuracy by ±1 through PID control algorithm.

Oil cooler provides two temperature control methods. Fixed type: Control the inlet or outlet oil temperature of Oil Cooler according to the customer needs. Synchronous type: The oil cooler can set the difference between oil temperature and ambient temperature (or machine temperature) to control the oil temperature. Oil Temp ° C Spindle displacement μ m 28 20 10 27 0 26 25 - 10 24 - 20 23 - 30 Note: The research result shows that the spindle deforms by 1um with the oil Temp. changes by 0.2 . The control precision of oil Temp. should reach ±1 to ensure the CNC working accuracy.

- 40 CONVENIENCE The front air inlet is used to remove and wash the screen The control panel is located on the front for user convenience The maintenance surface and the operation interface are on the same side for easy after-sales maintenance Customization can be adjusted according to customer power specification requirements LOW NOISE The large wind blade design can protect the air volume and greatly reduce the rotation speed and noise. CFD simulated and designed a new type of high efficiency axial fan to optimize wind blade shape; while the blade edge curvature is more reasonable, more efficient, and less noise. CLEANING.

EASILY COPE WITH THE HARSH ENVIRONMENT OF THE MACHINE TOOLS, ALSO NOT AFRAID OF ALL KINDS OF COOLING MEDIA AND CHIP WASTE WITH STRONG ANTI-CORROSION ABILITY. Add stainless steel filter to enhance structural strength while facilitating cleaning. Easily cope with the harsh environment of the machine tools, also not afraid of all kinds of cooling media and chip waste with strong anti- corrosion ability.
