              image.png

              Heavy – duty Valve Seat Boring Machine Model: BV120 , this machine makes use of special steel and 

              spheroidal graphite cast iron , its body are special heat treated , the rigidity , stability much improved 

              along with the working life. It is equipped with one heavy duty spindle , rated power is 2.5 kW , outside 

              diameter is Φ 90 mm , maximum torque is 42 N.M. . Moreover , the triple air-float patented work head , 

              and the air floating table , and other…… Thanks to that , it is really easy to operate , although this is

               a heavy machine. Designed for the valve seats from the smallest to the bigger diameter. This machine 

              can repair any existing engine, from the micro-engine up to the big stationary engine, machining capacity 

              from 18mm to 120 mm. To reach the requirements of high precision machining for valve guides with a

               small diameter of 4mm.
