Introduction
Thank you for purchasing a Kurt vise. You have just purchased one of
the best machine vises in the industry. Our new MX350 MaxLock 5-axis
vise is a welcomed product in our industry. The outstanding accuracy
of this product is second to none. Backed by a IRONCLAD lifetime
warranty, this product will last a lifetime when used and maintained
properly.
The original Kurt Anglock vises are designed for precision clamping.
The new 5-axis vise incorporates that time tested theory and give the
precision you need the in the area you need it. Having the clamping
screw directly below your work we can achieve maximum clamping
force and provide up to .0005 in clamping repeatability. It oers ultrahigh precision through many important features.
Features include:
1. A maximum of 40ft.lbs of torque providing up to 7000 lbs. of
clamping force.
2. .625 inches of stroke.
3. Pull type design to decreases stationary jaw deection.
4. Main screw is simple to machine and is 100% replaceable by the
customer.
5. Flexibility in mounting using auxiliary clamping slots provided on
the sides of the vise.
6. Fully machinable jaws for greater accuracy eliminating the need for
parallels.
The patented Anglock design allows the movable jaw to advance in
such a way that each pound of force forward induces a ½ pound force
downward which minimizes the jaw lift and increases accuracy. This
combined with the needle bearings increases jaw clamping pressure.

Set-Up Instructions
Set-up Instructions
The MX350 will come packaged and assembled in a ready to use state.
Check your list of parts with the items you have received with your
MX350 5-axis vise. You should have items 1 thru 23. These are the items
provided with the standard MX350 vise. Mounting bolts will be in a
plastic bag. Optional accessories will be addressed later in this manual.
The MX350 vise is designed to be mounted using a 2” center to center
mounting hole pattern (see Fig.1). Follow the steps below to set-up
your new MX350 for operation.
1. Remove the MX350 from the carton and rest it on the work surface.
2. Remove the main screw by rst removing the retainer that holds
the screw in place (item 7 & 22). Back the screw out using the
handle provided. The bearings and washers should come out with
the screw. DO NOT LOSE THEM.
3. Remove the chip guard (item 9 & 23) on the rear of the moveable
(item 1).
4. Next you will need to set-up the movable jaw. (see diagram 3) You
will note that there is a 1/4-20 set-screw in the rear of the movable
jaw. This will need to be backed out slightly. You can now remove
the movable jaw from the nut by lifting up on the movable jaw.
5. With the nut (item 3) exposed you will see another 1/4-20 setscrew that needs to be backed out. You can now slide the nut out
of the base.
6. Set your base on the work table in the area you wish to mount it
using the 1/2-13 SHCS provided. Lightly tighten the bolts to hold
the base in place.
7. Set the stationary side of the vise ( item 4) on the work table
opposite the movable base. Set it up so you have about 3/8” less
than the thickness of your part. (see diagram 2). Find the long1/213 SHCS (items 19 & 20) to mount the stationary with and tighten
them to 30ft.lbs. max.
8. Now you can tighten the SHCS in the movable base to 30ft. lbs.
9. With the movable and stationary base bolted securely to the work
table you can reinstall the nut (item 3). Re-tighten the set-screw in
until it stops and back it out 1/8 of a turn. (diagram 3)
10. Lower the movable jaw back on to the nut. Re-tighten the setscrew in until it stops and then back out 1/8 of a turn.
11. Replace the chip guard on the back of the movable base.
12. Screw the main screw back into the assembly until you can
reinstall the retainer.

Set-Up Instructions
Your new Kurt MX350 5-axis vise is ready for operation. Be sure to
use caution when clamping your parts and DO NOT exceed the
recommended maximum torque value of 40lbs of torque
Fig.1
Fig.2
Set this distance at approximately 3/8 inch less than the thickness of
your part.

Operating Instructions
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 aect 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.
