Last Glance at IMTS 2010
It would be impossible to cover all of the key exhibitors at IMTS 2010—even if every booth got merely a quick glance. However, the editors of MMS did get glimpses of some interesting technologies exhibited at the show...


Drop Trunnion Tilting Rotary Table
Distributed by Koma, the Tsudakoma RT-111,AA drop-trunnion tilting rotary table features a design in which the top surface of the spindle is the center line of the tilt axis. Two pneumatic rotary joints on the rotary axis allow automated clamping/unclamping of the System 3R chuck and pallet system.


Angle Head For Makino HMCs
Koma Precision stocks Alberti Slimline T90sl-0,3 angle heads, which are customized for Makino MAG3 HMCs. The angle heads feature an HSK 80F shank and a high speed NSK output, which can be equipped with a variety of micro-machining NSK tools.

Compact, High Speed Rotary Tables
Tsudakoma TN-101, TN-131, TN-161 and TN-201 compact, high speed, tilting rotary tables from Koma Precision use a dual taper, double-disc braking mechanism, which generates massive clamp torque—an increase of 320 percent when compared to previous models. The one-piece monoblock frame construction permits maximum rigidity. The tables feature an indexing and tilting repeatability of ±2 arcseconds and are available with a full range of options including rotary scales and various chucks and collets.


Automation Helps Move To High-Volume Production
This tool manufacturer had to automate its processes after switching from low-volume special orders to high-volume production runs. Since implementing Tsudakoma tilting rotary tables along with robotics and a pallet conveyor, the shop has increased sales by 400 percent.
