INTRODUCTION Thank you for purchasing a Kurt CTHDL6 6-inch Cluster Tower. This is one of the best workholding towers in the industry, with outstanding accuracy and repeatability. Backed by a lifetime warranty against workmanship and material defects, this product is built to last when used and maintained properly.
SET-UP INSTRUCTIONS Now that you have your new Kurt Vise, it’s time to set-up and begin using it. You will see that your new vise comes with a Kurt swivel handle. The handle is specifically designed to provide maximum torque to your vise (clamping force provided below).
1. Locate tower on machine pallet using edge locators or a center locator. Contact Kurt for optional center locators. 2. Bolt in place using English 1/2" or 5/8" English bolts or metric 12mm/16mm bolts (See page 16-17 for more details).
One-Sided Clamping: To properly clamp a part in your Kurt double-station vise, you should place the parts in the center of the jaws resting on the ways of the vise.
