Schwanog Has a Solution to Slow Change-Over of Insertable Form Drills

In many applications, grooving with insertable form tools instead of single-point turning has shown to provide unit cost reductions of as much as 40 percent. As the demand for complex turned parts continues to rise, production improvements such as these become even more significant. But the hesitation for the use of solid carbide drills often comes from longer change-over times, and thus higher costs due to machine downtime.

Stop in the Schwanog booth to see the company’s PWP and PWP-D insertable form drill system, which addresses the problem of long setup times due to the insert holder having to stay in the machine during insert change-over. Schwanog’s 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 with repeatability of 0.02 mm. The form drill systems are available in various carbide grades and offer additional savings in coating costs because only the insert must be coated rather than an entire solid carbide drill.

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 has 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, again, according to customer specifications, and can hold a minimum tolerance of ±0.02 mm as well.
