LATHE OPERATION AND CUTTING TOOLS

Lathe is a machine that helps in shaping several material pieces in the desired shapes.

Shaping up different materials and performing various functions such as sanding, deformation, cutting, facing, knurling, drilling, turning and much more is done with the lathe machines

Lathes Operations The general operations done with

the lathe are grooving, turning, cutting, sanding , etc

TYPES OF LATHE OPERATION

Common lathe cutting tools

types:1. facing/turning tools: Facing is the process of removing metal from the end of

a work piece to produce a flat surface This tool should be used if we need to shorten the

length of the stock or make the diameter smaller. Its main function is to face the stock so we can have a

nice smooth surface to work with.

2.The boring bar: This tool should be used if we need to make a hole in the stock bigger in diameter.

Before using this tool, there must already be a hole in the stock

3.Chamfering tool: Chamfering is the operation of beveling the extreme end of the work piece.

Chamfering is an essential operation after thread cutting so that the nut may pass freely on the threaded work piece.

This tool should be used if we need to make a chamfer on the edge of a work piece Or to break an edge.

4. Knurling tool: Knurling is the process of embossing a diamond

shaped pattern on the surface of the work piece. This tool should be used if we need to put a

knurling on our stock. This is normally used on knobs where better grip is needed.

5. Parting tool: Parting or cutoff is the operation of cutting a piece off by

slicing a groove all the way through it with a special parting or cutoff tool

This tool should be used if we need to cut some of the stock off to shorten it.

These tools are generally thin blades of HSS

6. Channeling tool: This tool should be used if we need

to cut a channel into the stock. Such as O-ring groves or any other small depth groove.

7. The Lathe bit: These can cut outside surfaces and

edges. There are versions that consist of a

piece of carbide brazed onto a rectangular steel bar.
