Customer Success Story

Here is a successful example with a vertical machining center. CML team evaluated the actual machining operations and machine usage, then designed a retrofit plan to upgrade the traditional hydraulic system. The system was equipped with high-efficiency IE3 motors with hybrid inverter technology and paired with a properly matched variable vane pump.
Using precision monitoring instruments (HIOKI power meter), we measured both instantaneous and cumulative power consumption. The upgraded system achieved approximately 53% energy savings, while maintaining stable oil temperature. This retrofit delivers multiple benefits: energy savings, reduced power consumption, and improved machining stability.

Hydraulic Applications in Vertical Machining Centers

• Tool Clamping System – Clamping and releasing unit
• Tool Changer – Arm rotation/movement and tool exchange
• Fixture Clamping – Holding workpieces securely in place
• Worktable – Rotation, positioning, and locking

Benefits of the ESG Hybrid Inverter Solution

• Significant Energy Savings – By adjusting motor speed based on actual demand, the system eliminates unnecessary standby time and reduces electricity costs by up to 53%.
• Extended Equipment Life – Controlled motor speed prevents continuous high-speed operation, keeping oil temperature stable. This helps extend the service life of hydraulic oil, seals, and other key components while reducing maintenance frequency and repair costs.
• Lower Noise Levels – Reduced motor run-time minimizes noise in the workplace, creating a quieter and more comfortable production environment.

Energy & Cost Savings: Before vs. After Implementation

After measurement, a traditional hydraulic system consumes 0.528 kWh per hour, totaling 12.69 kWh for 24-hour daily operation, which translates to an annual electricity cost of NT$16,687.

Energy-saving hybrid power system reduces power consumption to 0.248 kWh per hour, saving 53% energy. The annual electricity cost drops to NT$7,854, resulting in NT$8,833 in savings.

In terms of hydraulic oil consumption, noise level, power consumption, and operating costs, the energy-saving system significantly outperforms traditional systems.

Based on the power and cumulative consumption curves, energy-saving hybrid power system consistently maintains power usage at around 50% of that of traditional systems.
