Engineered with an optimized contour, weight, center of gravity, and cutting force, claw jaws bite into the workpiece with minimal loss of holding power. This provides maximum clamping forces and allows for more aggressive turning, faster cycle times, and improved shop efficiency. Available for most commercial chucks, these claw jaws provide increased clamping pressures on both the O.D. and I.D. of the workpiece. Clamping depth can be varied using workpiece stops, providing flexibility in machining. Many standard sizes are stocked while custom designs are available with no engineering fees. Manufactured from 8620 steel for durability and long service life, an extensive product range is ideal for I.D., O.D., and bar clamping applications.

5-axis portal milling machine

The FZU22 is a 5-axis portal milling machine for machining various workpiece shapes, sizes, and materials. Aluminum, plastic, wood, and other substrates can be processed, plus the machine is suitable for finishing carbon fiber reinforced and other composite materials. The overhead gantry provides precise production of models and molded parts. The standard machine includes a tool changer for 24 tools and a CNC from Siemens or Heidenhain for full motion control and tracking. A specially developed 5-axis milling head with 15kW spindle is suitable for machining contours and tight pockets in large molds.

The FZU22 boasts a substantial working range, from 71" to 98" in the X-axis, 118" to 138" in the Y-axis and 49" in the Z-axis. A feed rate of 2,756ipm in the X- and Y-axis is standard while the acceleration on the machine is max. 118in/sec2 to 197in/sec2. With a footprint of 11ft x 15ft, the machine fits easily in most shops. ISO 230-2 accuracy is provided. A choice of milling heads is offered on the machine to suit various applications.

Optional equipment includes touch probe, tool measuring system, work area cover, tool changer, chip conveyor, mist/dust extraction system, minimum quantity lubrication, and a vacuum system.

Hole deburring tool

COFA tooling allows for automated cross hole deburring applications, removing burrs from the front and back of a drilled through hole without stopping or reversing the spindle. For sloped, even, or uneven surfaces, the edge break is always even and consistent. COFA speeds production by automating deburring processes of hard-to-reach cross burrs which were formerly deburred manually, including elliptical holes and radiused edge breaks on flat parts. Sizes from 2mm to 30mm (0.79" to 1.19") are available from stock for immediate delivery.

Controlled by a simple spring, the carbide cutting blade follows the contour of the hole’s surface, removing all burrs while creating an even tapered corner break. The blade doesn’t cut as it passes through the bore and won’t damage the hole’s surface. The edge break begins only at the point where the blade contacts the material and then tapers the hole’s edge. This allows for faster feed rates since the tool slows itself down as it enters the through hole. The simple concept of the COFA tool has no adjusting screws or presetting requirements. Available in common tool size and spring strengths for various materials and hole sizes.

A range of COFA tooling is available, including COFA C for threaded holes and COFA Cassette for deburring larger bores.
