Boring tool performance depends greatly on the Length-to-Diameter (L:D) Ratio of the application. While this is a straightforward calculation, the Length and Diameter values to be used may not be that clear.

For manufacturers using milling chucks, pullout is a major issue, particularly when machining HRSA’s such as titanium or inconel.

There may have been a time when good enough was good enough, but in today’s competitive metalworking market, good enough won’t cut it.

ID boring is a common and time-consuming operation on CNC lathes. Common issues have led to the development of world-class boring tools—traditionally used on milling machines—that have proven to be just as effective on a CNC lathe.

If your work demands accuracy or you are looking to give your 5-axis capabilities a boost, hydraulic chucks are worth considering.

Anyone who’s made holes understands the difficulties that can arise: vibration, wander and even breakage. When it comes to production-level volume, these issues become even more limiting. Many turn to helical interpolation with a mill as a reliable way to rough out holes. We’re here to tell you there’s a faster, easier option.

Have you had a chance to read our recent article that appears in the Fabricating & Metalworking Magazine? Alan Miller, informs readers about different ways to absorb synchronization error.

This topic is important as toolholders provide the critical connection between a machine spindle and the cutting tool.

NTMA members visited BIG Daishowa Seiki in Japan during the association’s 2016 Tech Tour last month. The annual Tech Tour is a special opportunity for NTMA members to learn, network and tour manufacturing facilities outside the U.S.

Ansonia Manufacturing, the only machine shop in the town of Sonoma, California, discovered the EWN2-32ExER32 boring head and used it to complete a tricky hardware component job for a “live” glass art sculpture.

The first challenge to machinability – beyond simply working in titanium – for Colorado-based Cogitic Corporation was securing the cylinder in the universal machining center. It was also important to maintain access to the through-hole, which has an internal square key slot perpendicular to the stem hole.

Familiar name in NASCAR opens factory of the future and puts quality first.

Insufficient retention force of the spindle clamping mechanism could lead to reduced rigidity and vibrations, loss of machining quality, poor surface finish and shortened tool life. To help solve this problem, we have developed Dyna Force, a device for measuring the retention force of machine tool spindles.

A machine’s spindle is one of the key links in the machining chain. It makes regular inspection and spindle maintenance critical to getting the most out of your equipment and maintain process efficiency.
