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 WINSTAR is a CNC grinding machine with a 600 x 300 x 100 mm (23.6 x 11.8 x 3.9 in) maximum chuck and a 255 mm wheel on a 50.8 mm bore. It travels 780 mm (30.7 in) in traverse, 340 mm (13.4 in) in cross and 450 mm (17.7 in) vertically.

The wheel is the clearest difference from the WINSTAR SP beside it. The WINSTAR SP takes a 205 x 6.4-25 x 31.75 mm wheel, while this model takes 255 x 6.4-25 x 50.8 mm. The width range is identical, 6.4 to 25 mm, so both grind the same slots and forms; the larger diameter and the heavier 50.8 mm bore belong to the bigger frame, which also has the longer travels.

On size, the WINSTAR SP is listed with a 500 x 200 x 100 mm (19.7 x 7.9 x 3.9 in) chuck and travels of 600 mm (23.6 in), 250 mm (9.8 in) and 400 mm (15.7 in). The WINSTAR's chuck is half as wide again at 300 mm, the more useful gain for plates and for multiple parts set side by side.

Control is Simultaneous 2-axis + 1 axis: two axes move together to grind or dress a contour and the third positions. The wheel spindle motor row reads 3.7, the same value the WINSTAR SP shows, and Amada's table gives it no unit. Wheel speed, table speed and machine weight are not listed, so those need to come with the quotation.

450 mm (17.7 in) of vertical travel for tall fixtures
Simultaneous 2-axis + 1 axis NC control for contour work

Limitations

The wheel spindle motor row reads 3.7 without a unit, and no wheel speed is listed
Chuck width stops at 300 mm with 340 mm (13.4 in) of cross travel
No table reciprocation rate, table load or machine weight is listed

Frequently Asked Questions

01 What is the difference between the WINSTAR and the WINSTAR SP?

Size and wheel. The WINSTAR has a 600 x 300 x 100 mm (23.6 x 11.8 x 3.9 in) chuck, travels of 780 mm (30.7 in), 340 mm (13.4 in) and 450 mm (17.7 in), and a 255 x 6.4-25 x 50.8 mm wheel. The WINSTAR SP has a 500 x 200 x 100 mm (19.7 x 7.9 x 3.9 in) chuck, travels of 600 mm (23.6 in), 250 mm (9.8 in) and 400 mm (15.7 in), and a 205 x 6.4-25 x 31.75 mm wheel. Both wheel spindle motor rows read 3.7.

02 What grinding wheel does the WINSTAR use?

A 255 x 6.4-25 x 50.8 mm wheel: 255 mm in diameter, 6.4 to 25 mm wide, on a 50.8 mm bore. The wheel spindle motor is listed as 3.7 with no unit, and the table does not state a wheel speed.

03 What are the travels of the WINSTAR?

Traverse travel is 780 mm (30.7 in), cross travel 340 mm (13.4 in) and vertical travel 450 mm (17.7 in). Against the 600 x 300 mm chuck face that leaves the wheel run-off along the length and across the width.

04 What does the WINSTAR table not tell a buyer?

Wheel speed, table speed or reciprocation rate, table load, machine weight and services are not listed, and the wheel spindle motor value of 3.7 has no unit. The control row gives the axis arrangement, Simultaneous 2-axis + 1 axis, without naming the control model. All of these belong in the quotation.
