Y-axis turn-mill centre
CH5255SY Y-axis Turn-mill Centre
A slant-bed turning centre with a BMT power turret and a C-axis, so turning, milling, drilling and rigid tapping are completed in one clamping. X/Z/Y three-axis control brings shaft and disc parts off the machine finished.

Model FAQs
Questions Engineers Ask About The CH5255SY
Why does the CH5255SY hold its geometry under real work?
Two build points matter most on this machine: integrated stepped bed of large span, giving high rigidity and stable behaviour; and a 15° stepped x1-axis saddle and a 30° x-axis saddle form the interpolated y-axis, driven by a bmt servo power turret for heavy milling. 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.
Can the CH5255SY take bar or tube work through the spindle?
The CH5255SY carries a 1:20/MT No.6 / 1:20/MT No.6 / MT No.6/MT No.6 taper of spindle / sub-spindle bore. Remember usable bar capacity always runs smaller than the bore itself once the chuck or collet mechanism is in place, so check your maximum bar stock against the workholding you intend to run, not against the bore figure alone.
CH5255SY or CH5550DY — which fits my work?
Both sit in the y-axis turn-mill centre 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.
How soon can the CH5255SY ship, and what covers it afterwards?
Standard configurations generally ship within 30 to 60 days of a confirmed order, with the date written into the contract. The CH5255SY 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.
