FEATURES

1.

This machine may be used for surface cutting, drilling, milling, and tapping.

2.

The high quality of this machine, and its ease of operation makes it suitable for use by students,
amateurs, and home hobbyists, as well as skilled technicians.

3.

Drilling and milling may be done using hand operated feeding.  Milling is done with the quill locked via
Clamp Handle (#83) *.

4.

Many of the adjustable nuts are bronze, for adjusting thread clearance and reducing wear. These
bronze parts also allow screws to rotate smoothly and improve accuracy.

5.

The vertical column is very strong and stiff, which makes the machine very stable and improves
accuracy of manufactured parts.

6.

The machine head is cast steel, and has been heat-treated, stress-relieved, and precision machined.

7.

Machine gears are precision ground for smooth operation.

8.

Speeds can be easily changed.

9.

Thread tapping operations can be done in either rotation, and working depth can be controlled using a
positive stop gauge.
