The Whirling Process for Improved Worm Gears

Modern design, machining, and heat treating amount to huge savings for worm-gearing manufacturers.

Worm designs and manufacturing methods have changed very little over the past half century. Finishing a worm in soft material and then hardening it offers huge savings to worm manufacturers, but has not been considered viable because of distortions in the material from heat treating. Thread grinding has long been used as a finishing operation […]

High-Performance Grinding Solutions for Small or Large Lots

Reishauer’s RZ 400 is like no other generating grinder on the market today, and it can efficiently grind batches of five—or 5,000.

It used to be that if you needed to grind gears, your decision was limited to a slow-form grinder that was better suited for small lots, but not regarded as competitive for larger production runs or, alternatively, a machine considered to be a production-style “threaded wheel” generating grinder. The latter was well suited for 3,000 […]

Nachi’s Dry-Cutting Philosophy

The Nachi-Fujikoshi Corporation, and the Nachi Machining Technology Company, are hot on the trail of eliminating coolants from the tool-cutting process.

As with all manufacturing processes, the focus remains on piece cost and workpiece quality. Piece cost is primarily composed of the combined components of raw materials, the initial tool cost, tool sharpening and recoat, and the price of coolant, coolant disposal, machine cycle time, equipment depreciation, and general labor. As can be concluded, the cutting […]

Surface Coatings for Superior Gears

Surface-hardened materials are widely used in manufacturing gears, and carburizing, and sometimes nitriding, is normally used as a hardening treatment, which results in the reduction of macro-pitting–the main failure mechanism of hardened materials. This has to do with the extremely high local stresses due to the roughness of the tooth flanks.

For special applications, PVD coatings are now applied on a small scale. The coatings that are mainly applied so far are: B4C, WC-C:H (or W-DLC), and CrN. Bodycote’s U.S. operations, formerly known as Diamond Black Technologies, has played a pioneering role in demonstrating the capabilities of PVD coatings, especially B4C. In collaboration with Hauzer, Bodycote’s […]

The Next Dimension in Detecting Tooth Distortion

Process Equipment has developed new equipment and software that makes finding flaws a breeze.

The conventional CNC gear inspection machine will measure and evaluate helix and involute tooth flank deviations that are relative to a theoretically perfect helix or involute form. Any information relating to the actual mean tooth size, relative to a desired tooth thickness, is lost when plotting the traces. This is because the software is designed […]

The Simultaneous Dual Frequency Method of Inductive Gear Hardening

Once thought impossible, this new technology blends medium and high frequencies to create a new induction heating technique.

Inductive surface hardening is an attempt to harden only the surface of a structure without affecting the inner portions of the part so that internal tensile stresses are avoided. This is particularly important when it applies to gears. The tooth and root portions of the part must be surface-hardened in order to provide resistance to […]
