Schwanog Custom Form Tools Reduce Cycle Times

Schwanog’s insertable form tool system is designed to offer superior quality and high efficiency in the manufacture of precision parts for industries such as medical, automotive, aerospace and others.

The insertable tools can be applied to a variety of applications, including OD and ID grooving, form drilling, thread whirling, single-point threading, turning, milling, broaching of serrations, shaving, skiving and polygon turning.

The company says the system can be used on any type of machine such as a Swiss-type, conventional and multispindle automatic lathes, rotary transfer machines, horizontal and vertical milling centers and more.

The insertable tooling systems provide quick tool changeovers directly in the machine, which can result in sizable reductions in machine downtime while significantly increasing productivity. The system is also said to offer superior surface finish quality and high repeatability.

Additionally, Schwanog showcases its PWP and PWP-D insertable form drill systems, designed to address the problem of high setup times. The insert holder stays in the machine during insert changeovers, and its design allows the center height to stay unchanged. The insertable carbide tool is ground individually according to customer specifications and can hold a minimum tolerance of ±0.02 mm and repeatability is 0.02 mm. The form drill systems are available in various carbide grades.

As the insertable PWP and PWP-D form drill systems are limited to a maximum bore diameter of 28 mm and a depth of 16 mm, Schwanog added solid carbide drills to complement its line of form drill products for larger bore sizes and deeper holes. The solid carbide drills are ground individually according to customer specifications and can hold a minimum tolerance of ±0.02 mm as well.

Schwanog is also showcasing its thread whirling systems for the medical industry, which as said to provide high-quality, high efficiency manufacturing of bone screws. The systems offer process safety, chip control (burr-free threads), high-quality surface finishes and high repeatability (0.02 mm).

The thread whirling systems are available with 6, 9 and 12 custom cutters, ground individually according to customer specifications for either single or double-lead threads and can be adapted to any whirling attachment.
