CNC lathe for precision sizing DOUBLE SHELLS curvature of ceramic materials

摘要

The invention relates to machines for grinding inner and outer surfaces of thin-walled shells of double curvature of ceramic and composite materials. The utility model aims to improve the accuracy of shell processing. The machine comprises a frame (1) and the headstock (2), a carriage (3), the transverse slide (4), a turntable (5) and a tailstock (6) and two interchangeable sanding heads for respectively internal and external surfaces of the shells . The headstock is fixed to the frame comprises a spindle and spindle drive. The spindle is rotatably mounted in the sleeve with a smooth cylindrical outer surface. The sleeve is installed in the front and rear body supports the headstock. The housing of the spindle head is made of two detachable parts, isolating the horizontal plane passing through the spindle axis. Cover headstock by means of screws connected to its base. 4 ZP f ly-8-yl.
