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.

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.

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.

Not all pull studs are created equally.

When it comes to dialing in an ER system’s performance to match a specific application’s requirements or long life, there are three components to consider: the collet, the body of the holder and the nut.

The dream of Industry 4.0 is for machines on a factory floor to be connected, able to communicate with each other.

BIG DAISHOWA’s MEGA NEW BABY CHUCK has been delivering extreme precision for more than 20 years and is now available with up to ø1″ clamping for drills, reamers and finishing end mills with .00004″ runout accuracy.

Workholding plays a critical role in the metalworking equipment equation. Chuck condition is becoming even more important in multi-axis machining where additional angles and motion can amplify problems.

Making a hole with very tight tolerances is often a two-part process. When starting from scratch, a drill is used first to create the hole.

As our Engineering Manager, Alan Miller, likes to say, “You’re only as precise as your least precise component.”

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.

Charlie Mitchell, machinist for Andretti Autosport, spent up to eight hours setting up his five-axis machine with 10 tools to run 30 to 40 different processes on a part. Using UNILOCK pallets, set-ups times are 70 to 80 percent shorter.

When it comes to securely and accurately situating material on a machine table, there’s often more than one way to get the job done. With that in mind, consider these fundamental factors before purchasing new workholding.

We hear all the time how so many of our customers rely on the Unilock 138 series round workholding chuck for its mid-size diameter and adaptability to custom fixture designs.
