CNC Econimic Honing Machine EDHM16C Series

■ Spindle reciprocation controlled by hydraulic servo, with infinite variable speed and quick response.

■ The spindle is driven by a inverter motor, can achieve infinite variable speed.

■ Honing extension system is in hydraulic double-feed design, in which constant pressure control is ensured by use of hydraulic proportion controlling.

■ Variable pump is used in hydraulic unit. Cooling is forced by it, which guarantees constant temperature oil.

■ Circulation cooling is used in the cooling system. Magnetic-separating two-stage paper filter ensures clean honing fluid. Forced cooling is supplied by oil cooler so that the honing fluid is always kept in optimum temperature.

■ The machine can equip with an on-line metering and measuring system, which ensures consistency of honing tolerances.

■ The machine is controlled by high-performance programmable logic controller with TFT touch panel.
