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.

BIG DAISHOWA announces new negative inserts for its SW rough boring and EWN fine boring heads.

Lead angles close to 90° more effectively combat potentially damaging chatter and vibration because they apply the least amount of radial pressure.

BIG DAISHOWA introduces the newest addition to its SPHINX micro drill line. The new drill, made of fine-grained solid carbide, delivers exceptional tool life and consistent process reliability.

What to check when boring performance goes bad.

The importance of meticulously prepping, starting, and finishing holes can’t be emphasized enough.

Aerospace is unique among industries in its thirst for component accuracy with ‘blemish-free’ precision. Unlike any other industry, anything that goes into the air has to be on spec, as the smallest imperfection in machining can adversely affect flight safety.

Deep hole boring comes with challenges created by the inevitable deflection that occurs when trying to finish a hole of a substantial depth. Various factors determine the best approach to solving the issue, and it’s important to consider all factors before choosing a solution for your boring needs.

Two versions of the C-Centering Cutter, a multifunction cutter capable of spot drilling, centering and chamfering were on display at IMTS.

BIG DAISHOWA introduces the new R-Cutter (Pat. P) and BF-Cutter.

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

Many machine shops lack objective criteria for making toolholder purchasing decisions & most are made by price alone. However they can improve runout significantly by using the right toolholders.

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.
