Operating
Rules and Procedures PART TWO Machine
usage rules: 1. NOTE: Make sure you check
the lab entrance for new rules each time you come into the shop. Rules will be updated as need arises. 2. GENERAL RULES: a. When working at
any lathe or mill, sign in on the clipboard hung at that machine before
starting any work. this instruction also includes drill presses, saws and
grinders. b. Put any tools
used back where you found them immediately after use. Never leave tools
laying out on the table tops. c. You must use the
portable air filter if you are generating lots of smoke in your cutting
process. d. Report any tool
or machine that you damaged to a shop supervisor immediately. 3. CLEANING: a. Clean off ALL
(note this says ALL, not some) chips and excess oil from any machine and the
surrounding floor when you finish machining. This includes drill presses,
sanders, band saws, table tops, vises, etc. b. Use rags and the
small brushes stored in the "brushes" drawer of the tool box to
facilitate the cleaning process. c. When finished
cleaning, look back over the machine or area to see if there are any chips or
oil left. If there is any mess left on the machine, and your name is the
last name on the clipboard, your name will be written on the yellow card
board without consulting you.
You will then be called back to clean the machine properly. If you are not sure how clean is clean enough, ask a
shop supervisor. Students will provide both phone numbers & e-mail
listings. 4. SANDER RULES: a. Do not hold your
work piece with pliers, gloves, or rags. Hold piece with your hand and use
the bucket of water near the sander to cool the piece as it gets hot. b. Be careful when
sanding sharp corners or thin stock. These materials may tear the sanding
belt and/or get caught and result in injury. c. Be sure to clean
up the sander table top, base, and surrounding floor immediately when
finished with the machine. 5. BAND SAW RULES a. When using the
vertical band saw, do not use the wrong band saw blade or wrong speed for
the material you are cutting. See information sheets posted with each
blade behind the band saw for proper blade choice and blade speed. Ask for
help if you do not know how to change the blade. b. Do not place
hands close the blade when cutting material. Always use a block of wood or
scrap metal to push the work piece into the blade. c. Be sure to clean
up the saw table top, base, and surrounding floor immediately when finished
with the machine. 6. DRILL PRESS a. Be careful not to
drill into the vises or drill press table. b. Do not use Silver
and Deming drills in the drill press. Use the tapered drills for holes of
diameter larger than 1/2" inch. c. Use vises clamped
to the drill press table if there is the chance that your work piece might
spin when drilling. d. Only change drill
press speed while the drill press is running. e. Do not run the
drill speed too fast. If you hear any squeaking, the drill speed is too
fast or you are not plunging fast enough. Ask for help if you are not
sure what speed to use. f. Be sure to clean
up the drill press table top, base, and surrounding floor immediately when
finished with the machine. 7. GRINDING: a. Do not grind
any red painted tool bits, PERIOD. If you feel that a red painted tool
needs regrinding, ask a lab supervisor to do it for you. If you need a
specially ground tool, buy your own. b. The grinders are
meant only for tool grinding. Do not grind anything else on the grinders. c. Do not grind
carbide bits on the aluminum oxide grinder wheels. Ask if you do not
understand this rule. 8. LATHE RULES: a. Sign in (name,
tel.#, date) on the clipboard at the machine. b. Never have the
chuck key in chuck if your hand is not on the key. c. When changing
speed settings, make sure you turn the lathe spindle by hand to make sure the
gears mesh before turning on the machine. Ask for assistance if you do not
understand this rule. d. Do not put your
hand on the chuck to slow it down. e. If you hear
any squeaking or if the tool is deflecting largely while cutting, something
is wrong. Ask for help if you are not sure what is wrong. f. Clean up: - The following
pertains to the chuck, tool rack, tool holder, tools, tool post, all lathe
surfaces, and the floor. ~ remove all chips ~ wipe up all excess
cutting fluid - Use small brushes
found in the tool box and rags to facilitate the cleaning process. - Organize the tool
rack exactly the way it was when you got on the machine. If you cannot
remember how the rack as set up, look at the picture on the back of tool
holder. 9. MILL RULES: a. Make sure all
table and spindle locks are released if you feel any resistance to table or
spindle motion. b. Do not over
tighten the draw bar. Tightening the draw bar 15 degrees after you feel
resistance is enough. c. Be careful not to
drill into the mill vise, table, or parallel bars. Make sure there is
clearance for the drill or mill bit to pass through your work piece without
running into these surfaces. d. If using a mill
without dial speed changing you have to change the belts by hand. The belt
must remain horizontal - do not cross the belt. Ask for assistance if you do
not understand this rule. e. If using a mill
with dial speed changing, change speeds only while the machine is running.
Note that when going between low/high gear the machine must be stopped. f. When shifting
from low to high speed settings, make sure you turn the spindle by hand to
make sure the gears mesh before turning on the machine. Ask for assistance if
you do not understand this rule. g. If you hear
any squeaking or if the tool/part is deflecting largely while cutting,
something is wrong. Ask for help if you are not sure what is wrong. h. Clean up: - The following
pertains to the mill table, table slots, mill ways, vises, mill base, and the
floor. ~ remove all chips ~ wipe up all excess
cutting fluid - Use small brushes
found in the tool box and rags to facilitate the cleaning process. |
