Device for setting the working point of a tool in an NC machine tool

NC turret lathe comprising a tool turret rotatable about an indexing axis and mounted for rotation in a turret slide displaceable in a direction parallel to the indexing axis, also comprising a turret indexing drive monitored by a control mechanism for rotating the tool turret, and a slide drive monitored by a control mechanism for displacing the turret slide. In order to decrease the expenditure required to index the tool turret, the slide drive also constitutes the turret indexing drive, and the slide drive control also serves to monitor the turrent indexing drive. An actuatable coupling is provided between the slide drive and the turret to prevent undesired rotation of the turret when it is only to be slidably displaced.

NC turret lathe

Lathe apparatus is disclosed which in one form is an automatic turret lathe in which a single turret head is provided that can support a plurality of tools for performing machining operations on inside and outside surfaces of a workpiece carried on the live spindle of the lathe. The axis of the turret head is disposed at a preferred angular relationship to the axis of the live spindle, and the receiving or mounting surfaces for the inside and outside machining tools are disposed alternately around the axis of the turret head in planar arrangements that provide optimum operating conditions for utilizing the outside and inside machining tools on a single turret head. An attachment for preturning of workpieces is provided which can be mounted on the headstock to perform cutting operations wherein the cutting tool is moved in response to movement of the turret carriage of the turret head. Another attachment is provided to facilitate supporting of the workpiece during the preturning of the workpiece. The lathe apparatus also includes a tailstock construction for synchronous axial adjustment with the live spindle and also to permit pivotal movement of the tailstock relative to the live spindle. An improved automatic feed of bar stock is also provided.

Automatic turret lathe apparatus is disclosed in which a single turret head is provided that can support a plurality of tools for performing machining operations on both outside and inside surfaces of a workpiece carried on the live spindle of the lathe. The axis of the turret head is disposed at a preferred angular relationship to the axis of the live spindle, and the receiving or mounting surfaces for the inside and outside machining tools are disposed alternately around the axis of the turret head in planar arrangements that provide optimum operating conditions for utilizing the outside and inside machining tools on a single turret head.

Lathe with multiple tool turret

The disclosure relates to a method and apparatus for checking and monitoring the movement of a tool carriage in response to a numerical controlled program. The path of movement of the tool carriage is recorded independently of the program control during the initial run of the carriage, in a manner capable of being subsequently sensed. The recorded path is thereafter sensed during the subsequent runs of the carriage and a signal is produced when the carriage deviates from the recorded path. The recording device includes a stationary supporting member having a surface upon which a drawing or etching may be made. The drawing or etching member is mounted to the movable carriage so as to become jointly movable therewith. The sensing member is mounted in conjunction with the drawing instrument and is interchangeable therewith during the sensing portion of the procedure.
