(57) Abstract (Modified) Objective The curved surface processing machine whose process precision quite is high is offeredru. Constitution Rotary te for processing to which tool holder 10 is providedDecentering being able to point to buru 9, in rotary table 21 for the cross feedAxial support to do, decentering being able to point to this rotary table 21, for left and right feedAxial support it does in rotary table 22. The manufacture which is installed in principal axis 13The grindstone 37 which is installed in crop 14 and tool holder 10 revolutionWhile pointing, this to make touch, in reciprocal revolution of rotary table 9 the tsuThe Tip of the te and grindstone 37 vis-a-vis work 14 in normal direction directionThe ke te dot it makes contact. With this, front and back, time for left and right feedThe reciprocal time making revolution table move 21,22, grindstone 37 the sendingThe ri it cuts into. Advantages Revolution of motor for feed in rectilinear round trip movement conversion seWith the time motion of the zu and rotary table 21,22 grindstone 37Because you can send, in not needing the ball screw axis the tsuThe te, it can improve process precision.
