Takisawa TMX-2000

The Takisawa TMX-2000 is a B-axis multi-tasking machine with an 8 in (203 mm) chuck, a 500 mm (19.7 in) maximum turning diameter and 610 mm (24.0 in) of turning length. It is built in two versions: the TMX-2000 with an NC servo tailstock, and the TMX-2000S with a right spindle stock and a second 8 in chuck.

The table gives the travels: 640 mm (25.2 in) in X, 230 mm (9.1 in) in Y and 690 mm (27.2 in) in Z. The Y stroke is the figure to look at first, because it sets how wide a flat or how far off centre a hole can be on a part that may be 500 mm across. X, Y and Z all rapid at 40 m/min (1,575 in/min); the A axis is slower at 20 m/min (787 in/min). The B axis swings through 230° (±115°).

The tool spindle runs to 12,000 rpm on a motor rated 11 kW (14.8 hp) at S3 25% and 7.5 kW (10.1 hp) continuous. That is modest milling power for a machine that swings 500 mm: fine for finishing, drilling and pocketing with small cutters at speed, less so for heavy face milling. The left spindle reaches 5,000 rpm with 15 kW (20.1 hp) at 30-min and 11 kW continuous. On the TMX-2000S the right spindle also reaches 5,000 rpm but has 11 / 7.5 kW, and its bar capacity is 51 mm (2.0 in) against 65 mm (2.6 in) on the left.

Tool capacity is 40, with 80 as an option. Which version to buy depends on the parts. The tailstock version supports shafts within the 610 mm turning length. The S version takes the part over to finish its back face without a second setup. The S weighs 14,000 kg (30,864 lb) and the tailstock machine 13,700 kg (30,203 lb).

Floor space is 4,150 × 2,923 mm (163.4 × 115.1 in) and the height is 2,783 mm (109.6 in). Next to the TMX-4000, which turns 1,500 mm (59.1 in) and weighs 17,000 kg (37,478 lb), this is the short-bed machine for chucking parts and short shafts.
