Gear finishing apparatus with a helix compensation

Gear finishing apparatus

A first table (1) slidable leftwards and rightwards of a gear finishing machine and a second table (2) slidable forwards and rearwards of the machine are disposed in an overlapped relationship such that one of the tables is mounted on the top of the other table. Of these tables, the upper table is guided by a horizontal guide member (3) which is adapted to be rotated to any desired angular position and to be clamped at such position. A feed motor (5) drives the first table to slide. For sliding the table assembly along a diagonal direction, the angular position of the guide member is adjusted so that it extends along such direction. A horizontal stability of the table assembly is secured without employing a conventional parallel link mechanism. The table assembly is driven to slide so as to pass the center of machine so that an accuracy of gear finishing is assured.

Table sliding apparatus for gear finishing machines

Automatic cutter change type shaving machine

A machine tool comprising one or plural storage magazines which are mounted along the vertical direction rotatably around a vertical axis on an upstanding support frame structure at a side of working station. Each of the magazines stores at the periphery thereof a plurality of spindle heads, workpiece supporting jigs or tool supporting heads which are alternatively set one by one to a set position at the working station for operation on workpieces. Alternative setting of such heads or jigs is achieved by a selective rotation of each magazine and by a selective lifting and lowering of the head or jig between the set position and a store position just above such set position. Floor space required for storing and exchanging the heads or jigs is largely saved. A particular exchanging device for exchanging heads or jigs stored by the magazines for another heads or jigs is provided which greatly enlarges processings possibly carried out at the working station.
