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. Very little info for this mill is available online.

Please review this Basic Manual

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


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).


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.


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.


- Drill Chuck - (many more in varying condition)

Speeds & Feeds

Cutting speeds can be determined easily by using this cutting speed nomogram. The original cutting speed nomogram came from Ian at the BCSME.


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