Chuck Force Sensor Extensions and Accessories
Accessories for the chuck force include a variety of types of rest pads and extensions to match the gripping jaws on a turning-center/chuck.
Chuck Force Gauges - Wired
Designed to quickly check the holding force on a chuck or turning-center. The wired chuck force gauge can be customized for any diameter.
Wireless Chuck Force Gauges
The ForceCheck wireless chuck force gauge is designed to quickly and accurately measure holding force and speed on chucks. Verifying chuck holding force allows manufacturers to improve the repeatability of a manufacturing process by checking actual holding force under dynamic (rotating) conditions, as well as perform critical preventative maintenance checks. Contact us for other clamping diameters and extension rings, as well as 4+ jaw chucks.
Wireless Chuck Force Sensor Manual
The ForceCheck chuck force gauge is designed to measure the clamping forces created by a chuck. The wireless sensor can be used for either static (non-rotating) or dynamic (rotating) measurements. When rotating, the sensor can also measure RPM (Revolutions Per Minute).
Wireless Chuck Force Sensor Sets
Suitable for measuring RPM and force at the same time. These are complete sets that include sensor, standard rest pads, RPM magnetic wand, display, and padded carrying case. Contact us for custom sizes and multi-adapter sets.
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.
Large Diameter VTL Chuck Force Gauges
Measure clamping force on 12+ inch diameter chucks. Available as wired or wireless sensor unit. Base set is separate which includes wired or wireless read-out display, custom case, and accessories for the sensor.
Chuck Force Interpretation: Jaw Force vs. Total Gripping Force
The “Total Gripping Force” (F<sub>total</sub>) is defined as the arithmetic sum of the individual radial forces exerted by each jaw.
The force value shown on the ForceCheck display represents the measured radial force of a single jaw (F<sub>jaw</sub>) at the measurement diameter. This is different than the total gripping force of the chuck.
<strong>Calculating Total Gripping Force</strong>
Since the jaws move simultaneously and are driven by the same mechanism (usually a scroll plate or a hydraulic wedge), under ideal conditions the force is distributed equally among them.
F<sub>total</sub> = n × F<sub>jaw</sub>
Where:
-F<sub>total </sub>= Total gripping force
-n = Number of jaws
-F<sub>jaw</sub> = Force measured at a single jaw (value shown on ForceCheck display)
Examples:
3-jaw chuck
-Displayed Force Fjaw = 10 kN
-Total Gripping Force F<sub>total</sub> = 3 × 10 kN = 30 kN
5-jaw chuck
-Displayed force = 10 kN
-Total gripping force = 5 × 10 kN = 50 kN
<strong>Important Distinction: Force vs. Pressure</strong>
It is a common point of confusion whether the forces “cancel out” since they are opposing each other.
-<strong>Net Force on the Part:</strong> The vector sum of forces acting on a properly centered part is 0 kN. This is why the part remains stationary in the chuck.
-<strong>Gripping/Clamping Force:</strong> In terms of holding power and part deformation, we use the sum of the magnitudes. This total force determines how much friction is generated to resist cutting forces and how much the part might “crush” or distort.
<strong>Factors That May Change This Value</strong>
Your “real world” force may differ based on these conditions:
-<strong>Dynamic Loss (Centrifugal Force):</strong> If the chuck is spinning, the jaws want to fly outward due to centrifugal force. This reduces the actual gripping force. At high RPMs, the force when compared to a static condition could drop significantly.
-<strong>Friction and Lubrication:</strong> If you are measuring the force at the sensor but the other jaws are poorly lubricated, they may not actually be producing the same force.
-<strong>Part Geometry:</strong> If the part is not perfectly round or the jaws are not making full contact, the force distribution might become uneven, though the total input force from the chuck mechanism remains the same.
Lathe Spindle Face Ring
Series 492.026 ring gauges are for lathe spindle face.
Ring only: order plug gauge separately (see series 492.028 or 492.228)
SPH Pallet Clamping Heads
BERG Spanntechnik series SPH clamping heads are primarily used for horizontal pallet clamping. The heads form the basis of a highly rigid, high precision repeatable workholding solution. In addition to clamping heads, non-active units are available for setup and storage stations. Heads are supplied as a matched set with 0.005mm accuracy.
