Carr Lane Roemheld provides a full selection of state-of-the-art, air and hydraulically powered components and accessories. More than 80 different types of power workholding devices are available, allowing you to speed up and streamline many manual workholding operations. Compact, yet able to operate comfortably at 7,500 psi, power workholding products include flexible clamping systems, swing clamps, push clamps and cylinders, work supports, coupling systems, collet vises and many other workholding items.

 

 

Product Highlights

 

Hinge Clamp w/ Flat Clamping Lever  

Hinge Clamps have a sturdy linkage configuration that moves the clamping arm forward as it pivots into clamping position. This specially designed linkage allows the clamp to exert nearly perfectly vertical clamping force. The clamping arm retracts fully for clear loading from above. Ideal for clamping in narrow recesses. Durable, economical clamp with an easy-to-clean mechanism and standard metallic wiper.

Threaded-Body Work Supports

The support plunger is hydraulically extended and retracted by means of a small single or double-acting cylinder. Contact to the work-piece is made by spring force. The pressure spring can be easily exchanged. The support plunger is additionally guided in the area of the shaft diameter and can therefore absorb side loads up to 300 N.

Threaded-Body Work Supports 70 bar

Hydraulic work supports are used to provide a self-adjusting rest for the workpiece during the machining operations. They compensate the workpiece surface irregularities, also vibration and deflection under machining loads. Support force up to 900 lbs.

Why use Power Workholding?

AUTOMATION

Power-operated elements provide more control and a wide range of operations within a workholding system. Once adjusted, each product consistently clamps or holds. Powered work supports automatically adjust to minor workpiece irregularities. In addition, power workholding systems can operate multiple clamps and other devices in sequence to accomplish a multistep fixturing task.

SPEED AND SAFETY

Power Workholding Components greatly reduce loading times and are particularly effective for high-volume runs. Although initial costs are higher than with mechanical workholding, self-contained hydraulic workholding products are more efficient because fewer clamps (and accompanying personnel to operate them) are required. By replacing repetitive manual clamping, power workholders reduce operator fatigue. They allow remote control of inaccessible fixturing. Most systems also feature back-up controls for added safety in case of power failure.

UNIFORM CLAMPING FORCE

Since power workholders are controlled by a power source, the strength and fatigue of the operator have no effect on clamping force. Once set, force remains constant. And when more or less force is required for the next setup, the same clamps or positioners can beadjusted for those specific conditions.

SIMPLIFIED OPERATION

When operators have less physical labor in clamping and unclamping, they can run more machines and produce more. More workpieces can be loaded on fixtures for a given production cycle, which lengthens individual steps and requires less attention from the operator. Many types of power workholding can be performed by less-skilled workers.

N/C COMPATIBILITY

Versatile power workholding does not require design specialists. The same tool designer who designs the workholder can also design the clamping system. With their small size, Roemheld components are easy to locate. Standard fittings connect easily and ensure positive sealing.

COMPACTNESS

Roemheld power components are designed to fit easily on fixtures. Since they function well at fluid pressures up to 7500 psi, their smaller design can still provide high clamping forces. Small power clamps often allow loading more workpieces on a fixture because the clamps can be positioned closer together. A result is increased productivity through more parts per cycle.
