High precision CNC universal cylindrical grinder
MGK1450 / MGK1463 High Precision CNC Universal Cylindrical Grinder
Two CNC universal frames holding 0.0015 mm roundness and 0.0035 mm longitudinal cylindricity. Diameters to 500 mm and 630 mm, internal grinding to 250 mm bore, and a headstock that swings 90°.
Features
- High precision CNC universal frame: roundness 0.0015 mm and longitudinal section cylindricity 0.0035 mm.
- Headstock spindle rotates, and the headstock housing swings 90° anticlockwise, for taper and face work.
- Internal grinding to Φ250 mm bore and 320 mm depth.
- 325 mm three-jaw chuck as well as centre work.
- Inverter-driven headstock, 20-224 r/min on the MGK1450 and 10-100 r/min on the MGK1463.

Model FAQs
Questions Engineers Ask About The MGK1450 / MGK1463
Should my parts run between centres or in a chuck on the MGK1450 / MGK1463?
Between centres whenever several diameters must stay concentric to one axis — the centre holes are the datum, so inspect and lap them before precision work. Chucks or collets take over when there are no centres or a bore is the reference. On the MGK1450 / MGK1463, slender work past roughly ten diameters of unsupported length wants a steady rest carrying the span.
Why does the MGK1450 / MGK1463 hold its geometry under real work?
Two build points matter most on this machine: high precision cnc universal frame: roundness 0.0015 mm and longitudinal section cylindricity 0.0035 mm; and headstock spindle rotates, and the headstock housing swings 90° anticlockwise, for taper and face work. Structure decides how a machine ages — the specification table tells you what it does new, the build tells you what it does in year five.
What separates the MGK1450 / MGK1463 from the MGKW8250 in this group?
Both sit in the high precision CNC universal cylindrical grinder group, so the decision is capacity and duty, not kind: put your largest part dimensions, material and yearly quantity against each specification table and one of the two will run out of a figure first. Send the drawing and we will name which of the two fits — including the case where the smaller machine does the job.
What acceptance testing does the MGK1450 / MGK1463 go through?
Every MGK1450 / MGK1463 is laser-measured to ISO 230-2 over its travels, cuts a test piece that is measured rather than admired, and ships with a serial-numbered report carrying the measured values. If any line misses, the machine goes back into the shop until it passes — the report is a record, not a promise.
