An application engineer reached out to Kurt in search of a solution for a part being thrown from a vise during a heavy machine cutting. The part was being hogged out from an aluminum block measuring 12" wide x 6" tall. When the spindle reached the optimum RPM the vise deflected and caused the part to be thrown.
"Kurt engineers recommend the MaxLock HP440D 5-axis vise, which combats jaw deflection and part lift with Kurt AngLock design and Kurt's new patented lift control system. For heavy machining and precision parts, this could mean the difference between success or failure," said a company spokesperson.
Providing ±0.0005" repeatability, these MaxLock HP440D vises have a center line that easily adjusts to the center of the table rotation. Clamping can be achieved for both O.D. and I.D. while holding parts up to 6.690" long.
For maximum workholding flexibility, these vises are designed with three sets of jaws: serrated, and dovetail and machinable steel. Each jaw set provides three different clamping areas-at the bed, in the middle of the jaw and at the top of the jaw. Another important feature, vise jaws adjust from either side of the vise and have an opening capability of 2.190" to 6.690" depending on vise model and jaw option selected.
In addition, vise bodies are precision machined from 60,000 PSI ductile iron for maximum rigidity and vibration damping. These vises have hardened ways, 4140 heat treated steel jaws, 3/4" diameter screws for extra strength and heavy duty bolt down design with 1/2" cap screws. The vise screw is internally hexed for a smaller footprint.
MaxLock vises are available in 5", 7" and 9" models.
