Abstract
A CNC lathe jaw alignment system in which the position of the work holding edge of a chuck jaw is accurately located with respect to a work holding tool block mounted on a CNC lathe turret. A laser alignment tool is provided which includes a housing containing a light emitting laser module powered by a battery and an on/off switch. This laser module is used to project a laser beam onto the mounting face of a CNC lathe chuck to form a red target dot at the diameter of the workpiece. The laser alignment tool allows the lathe operator to visually see the workpiece diameter on the chuck as a red target dot generated by the laser module. This red target dot allows the operator to substantially expedite the process of accurately attaching jaws to a CNC lathe chuck in preparation for machining processes.
Claims12
The process for aligning the workpiece holding jaws on the chuck of a CNC lathe comprising:
- providing a CNC lathe having one or more tool blocks, a workpiece holding chuck, and a plurality of workpiece holding jaws having workpiece holding edges that are adjustably mountable on said chuck
- providing a laser capable of generating a narrow beam from a laser beam generating end thereof;
- providing a housing for the laser;
- mounting the laser within the housing;
- mounting a power supply for the laser within said housing and electrically communicating said power supply with said laser through an on/off switch to form a laser alignment tool;
- permanently mounting said laser alignment tool on or within the tool block of a CNC lathe with the laser beam generating end thereof facing said chuck and with the beam generated by said laser alignment tool being located on the centerline of said tool block and parallel to the centerline of said CNC lathe;
- assigning said laser alignment tool a location in the computer of said CNC lathe;
- determining the diameter of a workpiece to be held by the jaws of said chuck;
- instructing the computer of said CNC lathe to position said laser alignment tool so that its beam will strike said chuck and form a red laser target dot on said chuck at a target location where the workpiece holding edges of said jaws are to be located;
- activating said laser alignment tool to generate a laser beam which strikes said chuck at said target location;
- positioning a first jaw so that its workpiece holding edge is in alignment with said laser beam;
- rotating said chuck to the location of the remaining jaws and repeating the alignment step.
A CNC lathe having a laser alignment tool comprising:
- a CNC lathe having one or more tool blocks, a workpiece holding chuck, and a plurality of workpiece holding jaws mounted on said chuck;
- a laser alignment tool permanently mounted on or within said tool block;
- said laser alignment tool having a laser module located within a laser module housing;
- said laser module housing having a protective glass cover attached to the front end thereof and a front end cap sealing said protective glass cover;
- a rubber protective end cap located over said front end cap;
- a housing cap sealing the back of the laser module housing;
- and
- a power supply for the laser module located within said housing and electrically communicating said power supply with said laser module through an on/off switch.
