Clamprite Gage

Clamprite Gauge Kits provide an easy, accurate, and economical method of checking the drawbar force of your machine. Kits are furnished in a foam fitted metal tool box, and includes the gage head, a spindle adapter, and an internal transfer screw coupling that accepts all pull studs.
Belleville springs provide the only force that holds tools in the spindle while cutting. They are often the first to wear out on a CNC Machining Center. Drawbars can have over 140 Belleville springs in the stack. Just the slightest wear on each spring will have a big affect on clamping force, causing chatter, bad finishes, reduced cutter life, and scrapped parts. Left unchecked, a tool may eventually pull out during a cut, damaging the spindle, cutter, arbor, and fixture. Machines are never the same after a crash. Problems with repeatability, bad finishes, and short cutter life can be frustrating and difficult to diagnose. Up in the spindle and out of sight, draw bars seldom get the attention they deserve. To check it requires a special tool designed just for that purpose.
The Clamprite Gage simulates a tool in the spindle, and checks the drawbar in less than a minute. It has no batteries, clumsy cables, or delicate electronics. The force gauge reads directly in Kg force, so there are no conversions or calculations. Hundreds of shops in India, U.S. and around the world use the Clamprite Gage. Customers often say it paid for itself the first time they used it.
