Machine Structure
1) HT250 machine bed and feeding slider, tempering heat treatment to elimate stress and it is not easy to deformation.
2) High speed electrical spindle. Spindle speed: 4000~8000 rpm/min ( the speed can be adjusted ) spindle of grinding wheel is bearing structure and can ber axial force.
3) Feeding of parts is controlled by double servo motor to achieve the action control of the amount of cutting and automatic cycle.
4) Adjustment the amount of cutting is controlled by touch screen. can set permission password after commission.
5) Speed of CBN Wheel: 80-140 m/s.
6) Transmission system: ball screw and linear guide.
7) Feed guide rail, slider and ball screw are lubricated automatically by electrical fillong oil pump.
8) All sealed sheet metal except for loading & unloading parts ( we can install safety door lock system, it is up to customer requirement.
9) Total power: 16 KW.
10) Water pump: 20L/min Multi-step high pressure pump.
11) Air compression: 0.6-0.8 Mpa
Loading & Unloading mechanism
1) With automatic loading & unloading mechanism.
2) The rest action should be carried out with grinding at the same time except for loading & unloading.
3) The frame should be meet different size valve and easy to adjust.
4) The loading & unloading mechanism has proper protection and safety measures and don't prevent the operatot from changing the fixture, grinding wheel and other operation.
5) With water recovery apparatus device at the blanking way to prevent the fluid from leaking.
6) When the loading & unloading mechanism is out of order, no material or full on frame, the alarm shall be ring and the cycle will be stop automatically.
