Our best estimate for a cnc grinding machine in this class — not a quote from Amada. Configuration moves it a long way.
Overview
The Amada TECHSTER 84 is the first of three sizes Amada lists together with the TECHSTER 104 and TECHSTER 126: a CNC grinding machine with an 800 x 400 standard chuck, 1,000 mm (39.4 in) of traverse travel and 450 mm (17.7 in) of cross travel. The wheel spindle is rated 7.5 kW peak / 4 kW continuous and carries a 355 x 38-50 x 127 mm wheel.
Seen from below, this model is a TECHSTER 64 made longer and stronger. The TECHSTER 64 lists a 600 x 400 x 100 mm chuck, 780 mm (30.7 in) of traverse and the same 450 mm (17.7 in) of cross travel, with the same 355 x 38-50 x 127 mm wheel on a 3.7 kW spindle. The 84 keeps the width and the wheel, adds chuck length, and roughly doubles the listed power behind a wheel that can be up to 50 mm wide.
Spindle centre height is 500 mm (19.7 in) from the table. The radius of the wheel comes out of that, so the clearance under a new 355 mm wheel is well short of the full figure; measure tall fixtures against the wheel, not against the centre height. The table gives no separate vertical travel row for this model.
Control is Simultaneous 2 Axis + 1 Axis. The cross and vertical axes are both listed as Ball Screw Drive & Direct Drive. For the traverse axis the drive system row names the axis without describing its drive, so ask how the table is driven if reversal behaviour at the ends of a 1,000 mm stroke matters to the work. The TECHSTER 104 and TECHSTER 126 extend traverse to 1,200 mm (47.2 in) and 1,500 mm (59.1 in).

Strengths & Limitations
Strengths
- Wheel spindle rated 7.5 kW peak / 4 kW continuous, against a 3.7 kW figure on the TECHSTER 64
- 1,000 mm (39.4 in) of traverse with 450 mm (17.7 in) of cross travel over an 800 x 400 standard chuck
- 355 x 38-50 x 127 mm wheel: widths up to 50 mm cover a broad face per pass
- Cross and vertical axes listed as Ball Screw Drive & Direct Drive
- Simultaneous 2 Axis + 1 Axis NC control for form grinding
Limitations
- Spindle centre height is 500 mm (19.7 in), the lowest of the three sizes: the TECHSTER 104 lists 750 mm (29.5 in) and the TECHSTER 126 lists 850 mm (33.5 in)
- No vertical travel, table load or wheel speed row is listed for this model
- The drive system row for the traverse axis names the axis only, so the traverse drive type is not stated
- Cross travel of 450 mm (17.7 in) is the limit on part width; the TECHSTER 126 lists 660 mm (26 in)

Frequently Asked Questions
01
Traverse travel is 1,000 mm (39.4 in) and cross travel is 450 mm (17.7 in). The standard chuck size is listed as 800 x 400. Spindle centre height from the table is 500 mm (19.7 in); the table does not give a separate vertical travel figure.
02
Amada lists 7.5 kW peak and 4 kW continuous. The continuous figure is the one to plan long grinding cycles around, and the peak figure covers short heavy cuts. The wheel is 355 x 38-50 x 127 mm, so 355 mm in diameter, 38 to 50 mm wide, on a 127 mm bore.
03
Amada groups the three sizes together. The TECHSTER 104 lists 1,200 mm (47.2 in) of traverse, 460 mm (18.1 in) of cross travel and the same 7.5 kW peak / 4 kW continuous spindle. The TECHSTER 126 lists 1,500 mm (59.1 in), 660 mm (26 in), an 11 kW peak / 6 kW continuous spindle and a 510 x 38-50 x 127 mm wheel. The TECHSTER 84 is the shortest, at 1,000 mm (39.4 in) and 450 mm (17.7 in).
04
Length and power. The TECHSTER 64 lists a 600 x 400 x 100 mm chuck, 780 mm (30.7 in) of traverse and a 3.7 kW wheel spindle. The TECHSTER 84 has an 800 x 400 standard chuck, 1,000 mm (39.4 in) of traverse and 7.5 kW peak / 4 kW continuous. Cross travel is 450 mm (17.7 in) on both and both use a 355 x 38-50 x 127 mm wheel.
05
The cross and vertical axes are listed as Ball Screw Drive & Direct Drive. The drive system row for the traverse axis gives only the axis name, so its drive type is not stated in the table. NC control is Simultaneous 2 Axis + 1 Axis.
