Safety

THERE IS NO BELT GUARD FOR THE TOP OF THE MILL. ONE NEEDS TO BE FABRICATED

Always wear eye protection while using the mill. Do not use the mill if you do not know how to use this type of machine. If used improperly; workpieces of pieces of cutting tools can be thrown around the shop at high velocity.

Specifications: Mill

Mill is a Long Chang LC-15A. No specifications for this mill appear to be available online. The following information was measured from the mill and may be inaccurate.

Spindle Taper: Measured ~3.215in long, 0.8in minor diameter, 0.95in major diameter. Very close to Morse #3

Table: 1/2in T slots

Notes

To move mill head up and down (major vertical adjustment); you need to loosen two bolts on the right-hand-side of the head, and use the crank on the left-hand-side of the mill to raise or lower. Retighten securing bolts before use (when untightened, crank has huge slop).

Axes

X/Y - handwheels on table

Z - large grab handle on right of mill, or handwheel on front of mill. Black locking ring on grab-handle on right of mill engages/disengages handwheel. This axis can be locked via the small black lever on the front-left of the mill head.

Fixtures

We have a drilling vise intended for use with this mill that clamps to the mill table.

We have a set of 1/2in T nuts + fingers + step blocks for the CNC mill that will also fit this mill.

Tooling

- 1/4, 3/8, 1/2in collets - Drill Chuck - (many more in varying condition)

Tutorial

A written tutorial won't suffice! Don't touch the machine unless you've received training or used similar equipment!
