Mingxin MX600

Mingxin MX600 is the twin-head vertical grinding reference for RV-reducer pin-tooth parts and ring, disc, sleeve or housing features. The description includes bores, outside diameters, tapers, faces, segmented arcs and non-round forms in one clamping. Map the required surfaces and datum relationship before ordering: the available vertical/vertical or vertical/horizontal head pairings address different wheel access and grinding sequences.

The table lists minimum vertical-head bore Ø50 mm, maximum grinding outside diameter Ø600 mm and maximum grinding depth 400 mm at the vertical head or 100 mm at the R head. The faceplate load reference is 500 kg, while the pneumatic-chuck reference is 100 kg, 12 inches and Ø300 mm maximum clamping outside diameter. These are separate support limits; the larger grinding diameter and faceplate load do not establish chuck capacity.

Work-spindle speed is 10–150 rpm. X1/X2 slide travel is 800 mm and Z1/Z2 reciprocating travel 600 mm. The model description names Siemens 828D with 840D SL optional, magnetic-plus-paper filtration, separate dresser arrangements and optional in-process gauging or mist extraction. Identify the installed head, wheel, dresser, fluid and gauge package; axis feedback and the published six-axis label do not prove every axis interpolates simultaneously.

For an RV ring or interrupted internal profile, trial representative material/heat treatment, allowance, fixture and entry/exit geometry. Include dressing, gauging, coolant stabilisation and loading, then inspect the bore/face/profile relationship after release under agreed conditions. Catalogue working-accuracy figures lack complete part/test conditions and should not be guaranteed for every setup. Plan the 16 tonne mass and 3400 × 3800 × 3100 mm space reference; 60 kW is total machine power, not a grinding-spindle rating.
