Machine Finishing Workshop

DMG Mori Seiki LR-55A	DMG Mori Seiki LEO-80A
Sample Workpiece

The workpiece rotates while the cutting tool (called a "tool bit") is applied to shape the material.
This method is ideal for producing cylindrical objects with uniform dimensions.

Milling Machine

Vertical Milling Machine, Iwashita Corporation 2VB	Vertical Milling Machine, Iwashita Corporation 2RC
Horizontal Milling Machine, Iwashita Corporation 2HB	Sample Workpiece

Unlike a lathe, where the workpiece rotates, a milling machine rotates the cutting tool to perform machining operations.

As long as the workpiece is securely fixed—such as with the V-block shown in the upper right photo—it can process various shapes.

Grinding Machine

Surface Grinding Machine, Okamoto Machine Tool Works PSG 63SA-iQ	Cylindrical Grinding Machine, Toyota Industries Corporation GUS 32×50
Sample Workpiece

A grinding machine uses a high-speed rotating abrasive wheel to remove material from a workpiece.

Although it removes material slowly, it produces smooth and precise surface finishes.

Hobbing Machine

Kitai Industries 8-FN	Kitai Industries 8-F
Sample Workpiece

A hobbing machine is used to cut gears.

A hob tool rotates and is applied to the fixed workpiece to cut the gear shape.

Drilling Machine
