How much does the EMAG SN 320 cost?
Estimated price range
Our best estimate for a cnc grinding machine in this class — not a quote from EMAG. Configuration moves it a long way.
Overview
With Z travel of up to 2,700 mm (106.5 in) and workpiece lengths of up to 2,000 mm (78.5 in), the EMAG SN 320 is at the long end of the company's out-of-round grinding range. X travel is 500 mm (19.5 in), and all linear axes run on hydrostatic guideways.
Its figures are published jointly with the SN 310: diameter 360 / 640 mm (14 / 25 in), length 1,000 / 2,000 mm (39.5 / 78.5 in) and Z 1,700 / 2,700 mm (67 / 106.5 in). EMAG does not match these pairs to models. Someone who needs the 2,000 mm (78.5 in) capacity should make it a line item in the quotation, not an assumption drawn from the model number.
Set against the SN 208, the scale is plain. The SN 208 tops out at 950 mm (37.5 in) of part length on 1,600 mm (63 in) of Z, with 380 mm (15 in) of X. The SN 320 table reaches more than twice that length. Its 640 mm (25 in) upper diameter figure also opens it to large non-round parts beyond the 380 mm (15 in) capacity of the SN 204 and SN 208.
A part of that length and diameter is heavy, and the table lists no workpiece weight, so check the workhead and steady-rest arrangement for the actual component. Spindle and wheel data are not given either.

Strengths & Limitations
Strengths
- Up to 2,700 mm (106.5 in) of Z travel for parts up to 2,000 mm (78.5 in) long
- Upper diameter figure of 640 mm (25 in), against 380 mm (15 in) on the SN 208
- Hydrostatic guideways on every linear axis
- 500 mm (19.5 in) of X stroke
Limitations
- No workpiece weight limit is listed, which matters for parts of this length
- The table shared with the SN 310 does not say which paired values apply to the SN 320
- Spindle power, wheel size and control are not in the table

Frequently Asked Questions
01
The shared SN 310 / SN 320 table lists workpiece lengths of 1,000 / 2,000 mm (39.5 / 78.5 in) on Z travel of 1,700 / 2,700 mm (67 / 106.5 in). It does not tie the 2,000 mm (78.5 in) figure to the SN 320, so confirm it for the configuration offered.
02
The SN 208 lists 380 mm (15 in) of diameter, lengths of 600 / 950 mm (23.5 / 37.5 in) and 380 mm (15 in) of X. The SN 320 lists 360 / 640 mm (14 / 25 in) of diameter, 1,000 / 2,000 mm (39.5 / 78.5 in) of length and 500 mm (19.5 in) of X, with hydrostatic guideways on all linear axes.
