B: Check gullets of the blade. Check teeth and surface of blade. If a chip is packed or welded in the gullets do not use,
a blade in this condition will "thump" each time the blade passes through the part and could cause breakage. This condition
normally is evident when an over feeding conditions exists or when a blade is too fine for the material. The side of the blade
should not have any type of smear or build up on it. This happens when you cut too slow (some material like aluminum will do
this but will not affect the blades performance)
C: Always remove the back lash from the blade.
D: Always cut with coolant if possible. It is better to use too much coolant than not enough, it is better to mix your
coolant on the heavy side. This way you can add plain water to bring it up to level. Plus the rust inhibitors have a better chance
to work.
E: Select your blade properly. Using your calculator or contacting your blade supplier. If you are cutting tubing and
are having a problem with chatter, go to a finer tooth. Rule of thumb if you have to change blades or go to a finer tooth for
tubing. For solids use a heavier tooth blade.
F: Keep your blades sharp. Don't squeeze a few more cuts out of a dull blade. This may damage the blade and your
part. It also puts undue stress on the machine.
G: Always have your blade sharpened by a qualified professional. A cheap regrind will not give you good results. If
you need a blade resharpend and do not know of a reputable business, contact Dake. We will be happy to refer you to someone.
H: Never use a blade smaller or larger then stated in our specifications. Always use a blade with the correct pin hole
spacing and arbor size.
Cutting
A: Watch the chip. This will tell you all you need to know. A curly, silver colored, cool chip is what you want. If Chip
is different from this description change blade speed, head feed speed, or blade. Also make sure you have a sufficient supply of
coolant flowing on the part.
B: If the blade bucks or chatters, check your blade for conditions described above.
C: On material you have not cut before, make trial cuts. Always start out at a slow speed. Increase from here until it
sounds smooth cutting, at the fastest possible rate.
Operational
A: All doors and covers must be closed before machine will operate.
B: If machine stops in the cut you are in blade protection shut off mode. Check the following. Head feed rate to high,
incorrect blade (too fine), or the blade is dull. Correct problem and press the reset button on blade protection device, to
restart operations.
C: Always set the vises correctly.
D: Some material that is an unruly shape may require fixturing.
E: If bundle cutting round stock with out comb jaws, tack welding the end of the bundle will prevent parts form
spinning.
F: Thin wall tube may be crushed when clamping. A block with a hole bored through it then slit length wise, will hold
the tube with out crushing it. See next page for examples.
G: If you want to continuously feed one length after another, simply tape the pieces together end for end.
Always operate machine in a safe manner. Safety first to prevent personal
Injury Do not misuse this machine!!!!!!
