BIG Kaiser's Unilock Available With Adapter Kit for Haas Rotary Indexers

12/9/2013 - The flexible, modular Unilock Zero-Point Clamping System, offered by BIG Kaiser Precision Tooling Inc., is now available in a kit specifically designed for all Haas 160mm platter rotary indexing tables. Equipped with an ISM 160—a single chuck solution for the face of 4th or 5th axis rotary tables—the specially designed adapter rests between the chuck and the spindle face of the rotary indexer itself. Essentially, the design replaces the existing T-slot platter with an adapter, so the receiver goes directly onto the indexer spindle nose, and includes a pre-plumbed air solution. Read more here.

Doubling Down on Setup Reduction
Angle heads still find plenty of use for reducing setups, even in shops using sophisticated multi-axis machine tools.

The Benefits and Limitations of Machining With an Angle Head
Far from being outdated by the latest machine tool technology, angle heads often prove an ideal complement by pushing done-in-one capabilities even further. Proper application, however, requires attention to their limitations as well as their benefits.

The Big Step Up
A small shop added two new machines, each of which is more advanced than any of the previous machine tools the company has used. One of the co-owners committed to the work of bringing both of these machines fully into service. Here is the shop’s experience so far.

Innocent Until Proven Guilty
When something goes wrong with a machining process, it can be easy to misplace blame.

Thanks to a more rigid boring head from Big Kaiser Precision Tooling, a new machine that had been relegated to only roughing jobs is now holding the tight true-position and diameter tolerances that this shop’s customers have come to expect.

The Humble Pull Stud
I’ve said that the toolholder is the least appreciated element in many milling processes, but the pull stud (or retention knob) is perhaps the least appreciated component of the toolholder.
