WUXI MACHINE TOOLS 3MK1620 – Year 2014
CNC Grinding Machine
1.1. 3MK1620 designated for the pregrinding of raceways at outer rings of spherical roller bearings.
The Equipment is a best solution for large-scale manufacturing in a bearing industry.
1.2. Range of treated sizes (by diameter) of rings: Ø = 80…200 mm
1.3. Range of treated sizes (by width): 20…60 mm
1.4. 3MK1620 uses the principle of movement of table oriented mutually perpendicular. X-axis – workpiece spindle table, Z-axis – grinding wheel spindle table. The movement of the machine tables is carried out using articulated screw pairs (ball screws)
