-===== Safety =====
-Always wear eye protection while using the mill. VHS-specific training / orientation is required. If used improperly, workpieces or 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 {{ :tool:lc15_lc30_manual.pdf | Basic Manual }}
-The following information was measured from the mill and may be inaccurate.
-Spindle Taper: MT3 - Morse Taper #3
-Table: 1/2in T slots
-===== Notes =====
-To move mill head up and down (major vertical adjustment); you need to loosen two nuts 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 loose, 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 =====
-Currently setup with 4" wide [[https://www.grizzly.com/products/south-bend-4-lockdown-milling-vise/sb1248|milling vise]], the SB1248 from South Bend. Jaw plates are 4.163" wide and 1.381" high. Vise can be bolted to the table via T nuts / bolts. Never assume that the vise is aligned correctly; use a dial indicator to check.
-We have a set of 1/2in T nuts + fingers + step blocks for the CNC mill that will also fit this mill.
-===== Tooling =====
-- Drill Chuck - at the moment, the only chuck key that fits is on the drill press in the Fab shop area.
-- 2x Offset boring heads
-- Fly cutter. Takes an HSS toolbit, ground to the correct profile
-- 1/4, 3/8 and 1/2 collets. Used to hold end mills, fly cutters, and the small boring head
-- 2.5" face mill. Needs to be replaced, as all the carbides are chipped, and are not available for purchase. Still works reasonably well
-- Drift keys. USe to remove the tooling from the spindle. See document (pending) for use.
-- (many more in varying condition)
-- (Most) tooling is located in the red toolbox in the end of the (pending) work bench.
-- Set of Milling Vise Parallels from KMS tools, purchased February 2025
-- 3x.5" [[https://www.kmstools.com/magnum-1-2-quot-end-mill-2-flute.htmlendmills|endmills]] from KMS tools, purchased February 2025
-===== Speeds & Feeds =====
-Cutting speeds can be determined easily by using this {{:tool:cutting-speed-nomogram.png?linkonly|cutting speed nomogram}}. The {{:tool:lathe-cutting-speed.png?linkonly|original cutting speed nomogram}} came from Ian at the BCSME.
-===== Tutorial =====
-A written tutorial won't suffice! Don't touch the machine unless you've received training!
