BEMTW MKS1320
BEIER lists MKS1320 external grinding with the separately named MKS1620 end-face/external version on one original page. The base 1320 grinding envelope is Ø220 mm maximum swing, Ø200 mm grinding diameter, 160 mm centre height and 100 kg between-centres mass. Start with the centre holes, drive, journal positions, shoulder and unsupported spans of the actual workpiece rather than treating swing as the cutting diameter.
The base page offers centre-distance variants 320, 630 and 750 mm with machine masses 4500, 5500 and 6500 kg respectively. Headstock and tailstock centre references are MT4, with workhead speed 30–300 rpm and tailstock centre travel 60 mm. A long part, drive fixture or shoulder can constrain wheel access before reaching the nominal centre distance. The H/G 1320 references have a separate table and 50 kg loading reference, which must not replace these base figures.
The page describes servo-driven X/Z feed, a hydrostatic/hydrodynamic wheel-spindle arrangement, selectable diamond dressing behind the workhead and active measurement. It lists Ø500 × 110 × 203.5 and Ø600 × 80 × 305 mm wheel references and a 7.5/11 kW motor pair. Higher wheel speeds are special-order arrangements; agree the approved wheel, guard, spindle, coolant, dressing and gauge package instead of assuming all alternatives are installed.

The source labels its performance values as standard-testpiece results: roundness 0.002 mm, diameter consistency 0.003 mm for the 320 variant or 0.005 mm for 630/750, with different traverse/plunge/face finish references. Define a representative material, centres, allowance, wheel/dressing cycle, thermal conditions and released-part inspection for acceptance. The current shared image is marked MKS1620 and is explicitly a paired end-face illustration, not a 1320 delivery photograph; obtain the actual selected-build drawing and image.
