Hydraulic System for Machining Center
Background
- Test Machine: Horizontal Machining Center.
- The machine underwent maintenance and had Anypower servo hydraulic units installed.
Point
- The size of the oil tank for the old hydraulic equipment was reduced from 151L to 60L.
- The motor for the old hydraulic equipment was reduced from 7.5HP to 5HP.
- Temperature rise, vibration values, and current values all decreased according to actual measurements.
- The vibration value for the old hydraulic equipment decreased from 8.5u to 3.8u.
- There have been no maintenance records to date.
※ The reduced oil tank size leads to lighter weight and indirectly lowers carbon emissions.
※ Zero maintenance means zero service costs, saving company expenses.
Background
- Air compressor manufacturing plant
- First time adopting an energy-saving hydraulic unit.
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 its delivery in 2019, it has operated for over 25,000 hours.
- Energy-saving efficiency reached 80%.
※ 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.
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%.
