快换轧头(见右图)由轧头杆与偏心螺钉两零件组成。使用时,将快换轧头轻轻压入小内圆磨床主轴孔内,以4号莫锥定位。然后将弹簧轧头轻轻压入快换轧头孔内,以 R8锥面接触定位,依靠接触面的磨擦力,带动弹簧轧头转动,磨削弹簧轧头的孔。孔磨好以后,转动偏心螺钉,将弹簧轧头推出。快换轧头经过精加工,精度很高。保证了弹簧轧 Quick exchange head (see right) by the rolling rod and eccentric screw two parts. Use, the quick change rolling head gently press into the small bore grinder spindle hole to No. 4 Mo cone positioning. Then gently press the spring into the fast exchange head rolling hole to R8 cone contact positioning, relying on the contact surface friction, driven by the spring rolling head rotation, grinding the spring rolling hole. After grinding well, turn the eccentric screw and push the spring out. Quick exchange head after finishing, high precision. Spring rolls are guaranteed
