What to check when boring performance goes bad.

Boring tools with a digital readout aren’t the standard in U.S. shops, but their use is growing.

The return on investment from digital boring comes from the time saved making adjustments on the spindle, as well as the increased adjustment accuracy.

The limitations of using milling tools to prepare holes for finishing become apparent as hole depth and volume increase. Enter the relatively simple and affordable twin cutter, which can solve this and virtually any other holemaking problem.

BIG DAISHOWA has released two smaller sizes of the EWN Smart Damper precision boring heads, which eliminate vibration in deep-hole finish boring with a patented damping system.

BIG DAISHOWA has introduced the new, large diameter Kaiser 318 Series - a complete tooling system supporting a variety of aluminum and steel components optimized for twin cutter rough boring, precision finish boring and precision OD turning operations.

BIG DAISHOWA introduces the EWN & EWD Smart Damper - precision boring heads with a patented damping system to eliminate vibration in deep-hole finish boring.

When that inevitable job arises that requires higher RPM output, operators are left with the choice of replacing the machine altogether to gain higher productivity, or looking into an attachment, like a spindle speeder, to close the RPM gap.

The presetting machines available today are accurate, easy to use and provide closed-loop tool compensation on the CNC machine tool, saving significant time during job change-over.

Runout can be fickle, but finding a solution for it can pay significant dividends. How a little wobble can really increase your costs.

Here are some insights into the extra care and know-how needed to achieve success and build a successful reputation as a reliable supplier of micro machined parts.

Manufacturing miniature parts and features is not new. In the past, EDM and laser technologies were used to create these features. Although these technologies worked for low volume jobs, they are not practical for the high volume micro applications that are in demand today.

Micromachining, cutting where the volume of chips produced with each tool path is very small, is not a high-speed operation in relation to chip load per tooth. Rather, it involves a high spindle speed due to cutter diameter. The part may be physically larger, but details of the part require ultra-small profiles achieved only by micromachining. In other words, micromachining is not limited in scope to only miniature parts.

New inserts for indexable tools—C-Cutter Mini, C-Centering Cutter and Fullcut Mill—are optimized to extend tool life in stainless steel or aluminum.

With the addition of the Fullcut Radius Mill and the Ball End Mill, the Fullcut Mill Contact Grip series now features four connection sizes and seven cutter types.
