Drilling & Boring

A Look-Ahead item on a deep-hole drill with a continuously thinned web.

Time for a literature review.

While rotating counterclockwise, the cutting wing on the Erix Tool automatic back spotfacing tool folds in as it cuts a hole, then opens automatically when the spindle passes through the material and begins to rotate clockwise to begin spotfacing.

The latest addition to the Carmex Tiny Tool line—the multi-task CMR—allows users to bore, turn, face and chamfer with a single tool.

Reduce the time to rough bore bearing pockets. Twin roughing heads.

The Look Ahead section in the May 2015 issue of Cutting Tool Engineering magazine features an asymmetric line boring bar.

Boring heads that improve productivity.

KAISER Precision Tooling Ltd., Rümlang, Switzerland, reports that it has strengthened its long-term partnership, BIG Daishowa Seiki Co. Ltd., Japan, by agreeing to be acquired by the BIG Daishowa group as of April 15. KAISER Precision Tooling, a supplier of modular boring tools, and BIG Daishowa Seiki, a producer of toolholders and measurement devices, have had a technology and distribution partnership since 1980.

Automaker BMW challenged the Kennametal Inc. to develop a tool that accentuates the advantages of reaming and line boring while virtually eliminating the disadvantages. Kennametal accepted the task and developed its asymmetric line boring bar, which has two guide pads positioned so they only contact the last journal. This enables the boring bar to be quickly fed in and out of the multijournal bore without touching the workpiece. This geometry allows the bar to be fed through the raw, or unfinished, bores on an eccentric path.

I don't like bringing this up, but two key metalworking markets -- defense and energy -- are in a bit of trouble.

Table-type horizontal boring mills add versatility to machine shops.
