CAT/BT Drawbar Force Gauge (Spindle Clamp Force Tester)

Our Clamprite Drawbar Gauge Kits provide an easy, accurate, and economical method of checking the drawbar force of a spindle for your machine. A spindle drawbar pull force check frequently which takes less then a minute. This can increase tool life as well as save huge costs including a new spindle, downtime, or paid service. A spindle tool clamp force gage is also commonly known as a spindle drawbar dynamometer or Dyno. Our Clamp right gauge kits are furnished in a metal tool box and include the gauge head, a spindle adapter, and an internal screw coupling that accepts the pull studs. Collect pull studs from each of your machines and store them in the clamprite case for easy access.

Digital dynamometers cost three times as much and are more delicate and prone to problems when they are dropped or used during machine repair. Clamp rite is similar to Command and Forcecheck dyno or dynomometers.

Why is a Drawbar Dynamometer a must have tool for every machine shop?

• Cost of spindle $10,000-25,000
• Throwing tools? Injure employee? ATC problems?
• Cost of a service tech to determine why the machine accuracy is bad
• Cost of scrap parts
• Bad parts to your customer (Priceless!)
• Excessive tooling consumption- loss of rigidity
• Scheduled downtime not Emergency service
• Service companies may not have this tool in their van, which means they are looking for other problems. This check takes less than 1 minute.
• Ever wonder why you can't run some jobs on certain machines? drawbar force is low.

Pressure gauge size when ordering: Note gauge measurement is in pounds force feet (lbf ft). Most machine tools fall within the 3,000 to 5,000 lb range. It is rare that you would need a 10,000 lb. unit. A 5000 lb. gauge head is usually sufficient for most shops. If you do not have any 50taper machines we recommend the 3,000 lb. unit. If the gauge head is to be used for a wide variety of 30,40,50 taper spindles then we recommend the 5000psi drawbar force gauge.

Draw Bar Force Gauge Measurement Conversion

Optional- ISO adapter This is typically sold to Europe, Asia, and the surrounding countries. This adapter provides METRIC threads for the retention knob to screw into instead of standard inch threads. ISO 30 adapter needs both taper and coupling.

CAT/BT differences - The CAT 40 is .112 longer than the BT 40, (and the BT has a metric thread) two different taper adapters would be required as well as a coupling. The CAT and BT 50 Taper adapter is identical so an extra BT coupling is only needed to change over gauge head.
