Application
Oil cooling for Liebherr Gear Grinding Machine
Product Supplied
5.5 kw Industrial Oil Chiller
Background
Synnova Gears & Transmissions Pvt. Ltd. is a reputed manufacturer of high-precision gears, where tight dimensional accuracy and surface finish are critical. During continuous gear grinding operations on Liebherr machines, excessive heat generation in the hydraulic oil was affecting oil viscosity, machine performance, and component life.
Maintaining oil temperature within the recommended ISO VG viscosity–temperature range was essential to ensure consistent grinding accuracy and machine reliability.
Challenge
-
Rise in hydraulic oil temperature during prolonged gear grinding cycles
-
Viscosity variation affecting hydraulic holding force and machine repeatability
-
Increased wear and tear of hydraulic components and seals
-
Higher maintenance frequency and unplanned downtime
Solution
Himalaya Refrigeration Industries supplied a 5.5 kw cooling capacity Industrial Oil Chiller, specifically designed for hydraulic oil cooling in precision machinery.
The chiller was engineered to:
-
Maintain stable oil temperature under continuous load
-
Ensure oil viscosity remains within the ISO VG recommended range
-
Integrate seamlessly with the Liebherr gear grinding machine’s hydraulic circuit
Key Benefits Achieved
-
Constant Oil Temperature Control
Maintains hydraulic oil temperature as per ISO VG viscosity–temperature chart, ensuring consistent oil properties throughout operation. -
Improved Hydraulic Performance
Stable viscosity results in constant hydraulic holding force, improving machining accuracy and repeatability. -
Extended Seal & Component Life
Controlled temperature significantly increases hydraulic seal life and reduces internal component stress. -
Reduced Wear & Tear
Optimized lubrication conditions minimize friction and wear within the hydraulic system. -
Lower Maintenance & Downtime
Reduced oil degradation and component failure leads to lower maintenance costs and higher machine uptime.
Customer Outcome
With the installation of the 5.5 kw oil chiller, Synnova Gears & Transmissions Pvt. Ltd. achieved stable gear grinding performance, improved machine reliability, and long-term savings through reduced maintenance and enhanced hydraulic system life.
