Valve cut off machine is used for cutting off the stem of engine valve and to control the total length. Using CBN Wheel to cut. High precision with high efficiency
CNC Valve Cut Off Machine
Valve Cut off Machine is special purpose machine for engine valves. Using CBN high speed wheel to cut the stem of engine valve in order to control the total length of engine valve. Ranging from Stem diameter: 5-8 mm, Head diameter: 20-50 mm, overall length: 80-150 mm. Valve cut off machine can be single production and also can be connection production. Our equipment is continually upgraded with latest technologies in processing engine valve.

1) HT250 machine bed and feeding slider, tempering heat treatment to eliminate stress and it is not easy to deformation.
2) Feeding of parts is controlled by double servo motor to achieve the action control of the amount of cutting and automatic cycle.
3) Adjustment the amount of cutting is controlled by touch screen. can set permission passward after commission.
4) Speed of CBN Wheel: 80-140 m/s
5) Feed guide rail, slider and ball screw are lubricated automatically by electrical filling pupm.
6) All sealed sheet metal except for loading & unloading parts (We can install safety door lock system, it is up to the customer needs).
7) With automatic loading & Unloading mechanism.
8) The frame can meet different size valve and easy to adjust
9) With water recovery apparanus device at the blanking way to prevent the fluid from leaking
10) With alarm device
Valve Cut off Machine is special purpose machine for engine valve. it is used to process engine valves (inlet valves and exhasut valves) in cars, motorcycles, trucks, and other engine valves.
