High Frequency Angle Grinder HGC-250Ⅱ

 

Key Features & Technical Advantages:

1. Compact Design with Exceptional Power

  • Lightweight Construction: At 30% lighter than conventional grinders, the HGC-250Ⅱ ensures operator comfort during prolonged use without compromising structural integrity.

  • High-Speed Performance: Achieves peripheral wheel speeds of 72 m/s (4,300 m/min), enabling rapid material removal rates for hardened metals and composite materials.

2. Advanced Drive System

  • Three-Phase Squirrel Cage Induction Motor:

  • Delivers 240Hz/250Hz high-frequency output through a specialized generator or microcontroller inverter power supply.

  • Engineered for 0.5% speed variance under full load conditions.

  • Maintenance intervals extended by 40% compared to standard DC motor systems. 

Why Choose HGC-250?

  • Productivity Gain: 22% cycle times vs. traditional 50Hz grinders

  • Cost Efficiency: 18% lower energy consumption per workpiece

  • Safety Compliance: JIS certification with emergency brake


HGC-250Ⅱ
High frequency grinders are small, lightweight, feature high speed, and use a three-phase squirrel cage induction motor with simple maintenance for the fewest breakdowns. Use a specialized high frequency generator to supply high frequencies of 240Hz/250Hz or a microcontroller-controlled inverter power supply. High frequency grinders are capable of using 72 m/s (4,300 m/min) peripheral speed wheels.

    Cautions:
            · Do not exceed maximum R.P.M. marked on the wheels, never use sides of wheels for grinding or polishing, and make sure no chipping and
             no cracks at the edges of wheels.

            · Let the machine be idle for one minute before you start working. The machine must be idle for three minutes after you have changed the wheel.
            · The materials to be cut must be fastened on the machine.
            · Do not alter or change the metal center of the arbor hole if the size does not fit the machines.
            · Always wear face and eye protection.
            · Never remove protection guard from tools or machines.
