How much does the KAAST U-Turn 265/400 cost?
Price estimate
We do not have a price for the KAAST U-Turn 265/400 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The KAAST U-Turn 265/400 is a small, high-speed CNC lathe: a 6 in chuck on an A2-5 nose, a 6,000 rpm spindle and a 2,300 kg (5,060 lb) machine on a 2,240 x 1,700 mm (88 x 67 in) footprint. Maximum turning diameter is 370 mm (14.5 in) and maximum turning length 400 mm (15.74 in).
Speed is the theme. The spindle reaches 6,000 rpm on 9/11 kW (12.1/14.8 hp), and the rapid traverse is 30 m/min (98 ft/min). Both suit small-diameter parts, where surface speed needs rpm and much of the cycle is positioning. The larger A-Turn 300/700 tops out at 3,500 rpm and rapids at 24 m/min (945 in/min) in Z, but brings 18.5 kW (25 hp) and a 10 in chuck.
Bar work is limited by the spindle. The bore is 56 mm (2.2 in) and bar capacity is 44 mm (1.73 in). Travels are 400 mm (15.75 in) in Z and 185+15 mm (7.28+0.59 in) in X. Swing over the bed is 530 mm (21 in), and swing over the cross slide is 300 mm (11.8 in), which is the diameter limit for any part long enough to pass over the slide.
The 12-station turret is listed as Hydraulic/Servo and takes 20 mm (0.78 in) square shanks and boring bars up to Ø32 mm (1.25 in). A tailstock is part of the listed figures: an MT4 quill, 75 mm (2.95 in) in diameter with a stroke of 75 mm (2.95 in), and 350 mm (13.77 in) of tailstock travel. The table for this model has no rows for a control, live tooling or a C axis, so treat it as a turning-only machine until KAAST confirms otherwise. Height is 2,020 mm (80 in).

Strengths & Limitations
Strengths
- 6,000 rpm spindle, against 3,500 rpm on the A-Turn 300/700
- 30 m/min (98 ft/min) rapid traverse for short positioning moves
- 2,240 x 1,700 mm (88 x 67 in) footprint and 2,300 kg (5,060 lb) weight
- 12-station turret with 20 mm (0.78 in) square shanks and Ø32 mm (1.25 in) boring bars
- MT4 tailstock with 350 mm (13.77 in) of travel for supporting slender parts
Limitations
- Bar capacity is 44 mm (1.73 in), against 75 mm (3 in) on the A-Turn 300/700
- Spindle power of 9/11 kW (12.1/14.8 hp) limits depth of cut on larger diameters
- Maximum turning length is 400 mm (15.74 in), matching the 400 mm (15.75 in) Z travel
- The listed figures name no control, live tooling or C axis

Frequently Asked Questions
01
Bar capacity is 44 mm (1.73 in) through a spindle bore of 56 mm (2.2 in). The spindle has an A2-5 nose, a 6 in chuck and a top speed of 6,000 rpm, with spindle power listed as 9/11 kW (12.1/14.8 hp).
02
Maximum turning diameter is 370 mm (14.5 in) and maximum turning length 400 mm (15.74 in). Swing over the bed is 530 mm (21 in) and swing over the cross slide 300 mm (11.8 in). X travel is listed as 185+15 mm (7.28+0.59 in) and Z travel as 400 mm (15.75 in).
03
The listed figures include one. The quill has an MT4 taper, a diameter of 75 mm (2.95 in) and a stroke of 75 mm (2.95 in), and the tailstock travels 350 mm (13.77 in). That covers support for parts up to the 400 mm (15.74 in) maximum turning length.
04
The U-Turn 265/400 is smaller and faster at the spindle: 6,000 rpm, a 6 in chuck, 44 mm (1.73 in) bar capacity and 2,300 kg (5,060 lb).
