HSK – ISO 12164-1Note: Forces shown are "Recommendations for use and application. Forces will ensure that the portion acting on the flange surface is never less than 75% of the total. Lower clamping forces can be sufficient when operational loads are low (e.g. cutting forces in finish machining.) Conversely, higher clamping forces can be required when high operational loads are encountered (e.g. cutting and feed forces in heavy machining)."

• HSK-A/C 125: 100000 N / 22480 lb-f
• HSK-A/C 160: 150000 N / 33720 lb-f

Useful InformationDrawbar forces are typically measured in Newtons (N), kilo Newtons (1000 N), and pounds-force (lb-F). It is incorrect to refer to drawbar force in pounds (lb) or kilograms (kg) (forces due to gravity), or foot-pounds (a torque).

Conversion factors:
Newtons (N) x 0.001 = kN (kilonewton)
Newtons (N) x 0.2248 = lb-f (pounds force)
Newtons (N) x 0.102 = kp (kilopond)

Machine-Integrated Drawbar Force Gauges
Machine-Integrated Drawbar Force Gauges

The machine-integrated drawbar force gauge automates drawbar force measurement. With a wireless force sensor stored in the tool changer, a machine can periodically automatically check the drawbar without stopping production. Drawbar force is returned to the machine control via a wireless receiver, automatically alerting the operator if insufficient force is detected.

Collet Force Gauges
Collet Force Gauges

With the ForceCheck collet force gauge, the clamping forces on collets and hydraulic tool holders can be measured to obtain accurate machining specifications while fulfilling ISO standard requirements. Available in complete sets for 1/4, 1/2, 3/4, 1, 10 mm, 16 mm, 20 mm, 25 mm and other diameters.

Drawbar position gauges are used to adjust and set drawbar stroke position on HSK machine tool spindles. The gauges allow the clamping angle to be adjusted to the high and low limits, allowing the stroke position to be set.

Workholding 5C Collet Drawbar Force Gauge
Workholding 5C Collet Drawbar Force Gauge

ForceCheck collet force gauges measure the drawbar pullback force of a collet workholding system. Measurement of collet drawbar force provides an easy way to ensure correct force from machine to machine, or between setups for different parts.

Automatic Hydraulic Drawbar Style Clamping Systems
Automatic Hydraulic Drawbar Style Clamping Systems

The hydraulic die clamping system with drawbar style clamping is designed for clamping dies of different widths on press slides. The clamping actuator moves automatically into the T-slot of the press slide between the parking position and the respective die. The clamping element can clamp different clamping rim heights due to the long clamping stroke of the double acting cylinder. Hydraulic pressure is at a maximum 400 bar.

This critical performance -- the tool clamping force -- is often never measured after a machine is put into service. Regular verification allows problems to be detected early so maintenance and repairs can be scheduled. As a result, emergencies and unexpected downtime can be avoided. When troubleshooting, drawbar performance can quickly be verified.
