Hydraulic System for CNC Lathe
Background
- Automobile Transmission Shaft Processing Factory
- There are more than 120 CNC lathes in the factory.
- From 2019 to 2021, 15 Anypower servo hydraulic units have been replaced one after another.
Point
- All 15 units have been running for over 10,000 hours each.
- There are no maintenance records to date.
※ Although the initial purchase cost is higher than traditional options, the electricity bill has already been recouped.
※ Zero maintenance means zero service costs, saving company expenses.
These are actual measurement data from Company W. There are 15 servo hydraulic units
Testing Period:
From 1 pm March 1, 2018
To 11am Sep 6, 2018
Total operated 4088 hours
Total power consumption: 665.8 kwh (0.163 kwh per hour)
24 hours operation test (Mon to Sat)
Produce 1 component in 52 seconds.
Average producing 48 component in one hour
takes Servo hydraulic unit 0.16 kwh
and takes piston type hydraulic unit 0.68 kwh.
Conclusion: Servo hydraulic unit saves 76% energy than piston type hydraulic unit

Background
- Company P purchased two machines from Japan's Company M.
- Both machines were originally equipped with traditional hydraulic units from Anypower. One of them was replaced with AnyPower servo hydraulic units.
Point
- The tank size was reduced from 20L to 15L.
- The motor was reduced from 2HP to 1HP.
- Improved temperature rise, noise levels, and vibration values were observed.
- Since the replacement with servo hydraulic units in 2019, there have been no maintenance records.
- Energy-saving efficiency reached 79%.
