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.

BIG DAISHOWA expands jet-through hydraulic chuck line to include the BCV interface and additional inch sizes.

MEGA New Baby Chuck is now available up to ø1" clamping for drills, reamers and finishing end mills with .00004" runout accuracy.

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.

The medical industry pushes the limits of precision for machining and tools. The trend toward less-invasive surgery using smaller parts translates to a need to better control the preci­sion and tolerances of micromachining processes.

In-machine laser technology is touted by machine tool builders and distributors as the way of the future and an indispensable tool for machinists. Do you really need an offline presetter if you have in-machine lasers?

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.

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.

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.

After researching presetters for eight years—including four trips to IMTS—CEO Ronda Peterson knew it was the time to invest in the next level of efficiency for her shop.

Good measurements make setups faster, reduce recuts and identify potential spindle or holder issues before they become bigger problems. Let’s look at a few of the key areas to measure and the handy solutions available.  

Because of the popularity of BIG-PLUS, many tooling companies, without a proper license, offer what they call dual-contact tooling. But not all dual-contact is the same. Let’s tackle a few of the most common misconceptions.

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.

As we close out 2020, and our 30th anniversary celebration, we take one last look back at BIG DAISHOWA’s role in the evolution of boring tools.

Accurate offsets and workpiece reference points are critical to effective setups and first-part accuracy. Taking a manual approach or attempting to verify these in the machine without the right measuring devices can be a delicate and time-consuming process.
