Operating Instructions
For proper vise operation insert the handle on the hex end of the vise.
Rotate clockwise to clamp and counterclockwise to unclamp your vise.
This handle combined with the correct amount of torque will provide
you with all the clamping force you will need to machine your parts.
A high quality calibrated torque wrench can be used if needed. The
maximum torque for the MX350 is 40ft. lbs. This will yield approx.
7000lbs of clamping force. DO NOT use any other type of pressure to
open or close your vise.
To properly clamp a part in the MX350 5-axis vise and for the best
accuracy and repeatability you should machine the horizontal surface
of the jaw. (Fig. 4) This is best done after you have the vise completely
set up and ready for operation. Insert a small piece of material in the
vise just below the step in the jaw as shown in diagram 4. Tighten the
jaws on the part and hold tight. Run the cutter down the horizontal
surface on both sides of the vise removing approximately .005 of
stock. Be careful not to cut the vertical surfaces if you can. This will true
up the jaw and make for a very accurate repeatable vise. If you choose
not to cut your jaws you can expect a tolerance of +/- .005 on the step.
The standard jaw is hardened to 40RC and is coated with a black oxide
treatment. Your vise is now prepared and ready for full operation. Be
sure that all screws are tight and guards are in place.
NOTE:
The tolerance build-up will affect the location of the step in the
“Z” axis. Mill to clean up the horizontal surfaces of the step jaws when
the greatest accuracy is needed. (Fig.4)
WARNING:
The use of handle extensions, air impact wrenches, breaker
bars or hammer strikes are not recommended and will void
the warranty if used. This can cause damage to the thrust
bearing and screw threads.
