Honing systems

Honing and super-finishing stones and mandrels for two-stone honing are available for industrial and automotive applications. The system is designed to fit all small horizontal-spindle honing machines and simplifies both tooling selection and setup.

The two-stone hones provide constant abrasive contact at all times. Because two stones are cutting, they give faster stock removal and better finishes than are obtained with conventional hones using one narrow stone paired with a guide shoe. Two-stone hones are an economical, rapid, and simple way to finish bores from 1/16" to 3", including bores containing keyways, crossholes, or other interruptions.

Overhead presses

Patented "overhead" electromagnetic presses are said to allow punching and stamping velocities up to 750 times greater than those achieved by hydraulic or mechanical presses. The presses can deliver over 100 tons in thin materials.

Without the need for a massive, much larger conventional press, the Lourdes press accelerates tools into and through a wide variety of materials much like a bullet. Advantages of the high-velocity process include burr- and string-free edge quality; use of lighter weight, less expensive tooling; and minimal heat transfer from the work to the tool. This can extend tool life up to 10 times, depending on the material processed. Standard models feature work areas from 4 1/2" x 6" to 16" x 22 1/2".

Heavy-duty roughers

Series 27J2V cutters are designed for heavy-duty roughing cuts in steels, stainless steels, and cast iron. Reduced cutting forces and horsepower consumption result from positive axial geometry and chip splitter inserts. To counteract the heavy force of cut, a left-handed helix forces the cutter into the spindle. The On-Edge insert configuration directs cutting forces through the thickest portion of the carbide. Series 27J2V cutters are available as end mills in diamters from 2.000" to 3.000" and as shell mills in 3.000" to 4.000" diameters.

Double-sided machine

Double-sided Machining (DSM) is a precisde finishing system capable of lapping, grinding, diamond, or soft polishing both sides of a workpiece at once for flat, parallel parts with burr-free, sharp, straight edges. The DSM method provides faster machining at lower pressures by using an abrasive slurry to continually present new, sharp abrasive edges to the workpiece. Two air cylinders move upper and lower lapping and polishing plates, ensuring a response to changes in air pressure. Fragile workpieces of different thicknesses are easily handled. Automatic thickness control is available for precise part thickness and repeatability. Size control accuracies of 0.000 076" and parallelism control to 0.000 025" are attainable.
