ABSTRACT:
Disclosed is an improved inner surface shaper comprising, on a bed, a first reciprocating stock having a first working spindle and a drive screw, a servomotor to drive the drive screw for making a linear reciprocation of the first reciprocating stock, a second reciprocating stock having a second working spindle, a hydraulic cylinder to drive the second reciprocating stock toward and apart from the first reciprocating stock, and a tool rest placed between the first working spindle and the second working spindle. The first working spindle, second working spindle, drive screw and hydraulic cylinder are arranged along the center line of the bed, and the hydraulic cylinder and first reciprocating stock are connected by two joint rods which are arranged symmetrically with respect to the center line of the bed.
This arrangement has the effect of directing undesired counter force to the joint rods and the longitudinal axis of the drive screw. Thus, there is no fear of causing any distortion as would bend either working spindle or would injure the threads of the drive screw.
