Drawbar Clamping Force Gage
DRAWBAR CLAMPING FORCE GAGE
CNC Machines using pull-studs for tool retention experience a slow but progressive loss of tool holding pressure from the time the machine is new. This little known fact has a major impact on surface finishes, cutting tool life, and on your productivity. Testing a drawbar requires a force gage which simulates a tool being held in the spindle. The Clamprite Gage uses a common tool holder as the interface between the gage and machine spindle, eliminating the need for a high-priced precision adapter for each different spindle size (only HSK-type spindles require an adapter).
The Clamprite Gage was designed for accurate spindle tension testing right on the machine. The actual pressure exerted by the spindle drawbar mechanism is read directly on the dial, so there is never a need for any calculations or conversions. Drawbar force checking is made easy using the Clamprite drawbar force gage. Drawbar testing takes less than one minute, so production time is barely affected. Its simple and rugged design requires no batteries, electrical cords or delicate electronic components to pre-set, calibrate or burn out.

Clamprite HSK Spindle Adapters
HSK spindles must maintain factory specified drawbar force to properly seat the arbors. Test HSK spindles frequently!
Our product sheet only shows the E and A size adapters. Call for information if you have the F or other size adapter and we will tell you which of our part numbers corresponds to your adapter. For example, the HSK F size spindle can be tested with the next size larger adapter in type A configuration. Most of Clamprite's spindle adapters are listed in the type A configuration.
If you have already purchased a gage kit with the universal gage head you can simply add the HSK adapters you need. If you only have HSK spindles you will need to order the appropriate gage head as shown below.
HSK spindle data can be confusing. If you want to end the confusion and learn the whole story, order our HSK Handbook. To order any of these items enter the Part Number into the search bar above. (This will take you to the product page where you can add the item to the shopping cart)
