1 Flexible Manufacturing Working with Machines Copyright © Texas Education Agency, All rights reserved.

2 Work Mounting Procedures: Lathe Material can be mounted in various ways: Three-jaw chuck Four-jaw chuck Collet chuck Turning between centers Copyright © Texas Education Agency, All rights reserved.

3 Chuck Copyright © Texas Education Agency, All rights reserved. A chuck is used to hold round or octagonal material in a machine.

4 Three-jaw Chuck Copyright © Texas Education Agency, All rights reserved. A three-jaw chuck is used to clamp material for more accuracy. The three jaws move in unison.

5 Four-jaw Chuck Copyright © Texas Education Agency, All rights reserved. A four-jaw chuck is used to hold square or odd- shaped material in a lathe. The four-jaw chuck is also used to turn a cam- shaped part. The four jaws move independently.

6 Collet Copyright © Texas Education Agency, All rights reserved. A cone-shaped sleeve used in a lathe for holding round material or milling machine to hold an end mill. Collet Taper

7 Collet Chuck Copyright © Texas Education Agency, All rights reserved. Collet Chuck Collet A collet chuck is round on the inside and tapered on the outside. The tapered outside tightens into the chuck causing pressure to hold the material in place.

8 Turning Between Centers Copyright © Texas Education Agency, All rights reserved. Faceplate with Lathe Dog

9 Turning Between Centers Copyright © Texas Education Agency, All rights reserved. Turning (mounting) between centers is a way to machine material between the headstock and tailstock centers. The centers are tapered to match the 60⁰ angle of the center-drilled material.

10 Turning Between Centers Copyright © Texas Education Agency, All rights reserved. Faceplate with Lathe Dog A lathe dog is a clamp that transfers rotation from the lathe to the material mounted between the headstock center and the tailstock center.

11 Turning Between Centers Copyright © Texas Education Agency, All rights reserved. Faceplate with Lathe Dog Faceplate is a flat plate with slots that screw onto the lathe headstock. This device turns the lathe dog.
