CNC wide wheel cylindrical grinding machine
MKKZ Series CNC Wide Wheel Cylindrical Grinding Machine
A 300 mm wide wheel, so a journal is ground in plunge rather than traverse. A radial in-process gauge closes the loop and holds outer circle accuracy below 0.003 mm. Two frames, to 630 mm diameter over 4000 mm and 1.5 t.
Features
- Wide wheel: 300 mm across the face, so a journal is ground in plunge rather than traverse.
- Radial in-process gauge with full closed-loop control, holding outer circle accuracy below 0.003 mm.
- Two frames: 320 mm diameter over 1000 mm, and 630 mm diameter over 4000 mm carrying 1.5 t.
- SIEMENS 828D as standard.

Model FAQs
Questions Engineers Ask About The MKKZ Series
Should my parts run between centres or in a chuck on the MKKZ Series?
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 MKKZ Series, slender work past roughly ten diameters of unsupported length wants a steady rest carrying the span.
Why does the MKKZ Series hold its geometry under real work?
Two build points matter most on this machine: wide wheel: 300 mm across the face, so a journal is ground in plunge rather than traverse; and radial in-process gauge with full closed-loop control, holding outer circle accuracy below 0.003 mm. 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.
Which parts suit the MKKZ Series best?
The catalogued work list for the MKKZ Series covers motor shafts, rubber rollers, crankshafts, shaft parts generally. If your part sits outside that list it is not necessarily wrong for the machine — send the drawing, the material and the tolerance and we will place it honestly, on this machine or another.
MKKZ Series or MKS27 Series — which fits my work?
Both sit in the cNC wide wheel cylindrical grinding machine 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 is the lead time and warranty on the MKKZ Series?
Standard configurations generally ship within 30 to 60 days of a confirmed order, with the date written into the contract. The MKKZ Series then carries a 12-month warranty on main components, handled by the plant that built it, with lifetime technical support and spare parts identified by part number at handover.
