Koma Precision Inc.

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.

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.

 In addition to its line of Alberti Slomline NSK output angle heads, the company now offers Alberti NSK output TurboFlex and TurboDrill air driven tools. These air driven tools operate at up to 58,000 rpm and are offered with a full range of NSK micro machining outputs. Alberti NSK output live tools are also available on a special order basis.

The RNA-S, RBA-S and RBA-K, S series rotary tables have an indexing speed ranging to 88. 9 rpm. These high speed rotary tables are said to increase productivity not only by decreasing cycle times, but also by enabling smoother surface finishes, thereby reducing secondary machining requirements.

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.

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.
