Conventional vertical lathe
DVT51 Conventional Vertical Lathe
A programmable single-column vertical lathe, extended from the CK51T series and upgraded from the conventional range. A servo feed motor and ballscrew replace the trapezoidal leadscrew and feed rod, and PLC control replaces relay logic, so the structure is simpler and the failure rate lower. The cross rail is extended with twin ballscrews and symmetric ways, which both steadies it and makes room for a magazine. The magazine uses a T-block tool pull mechanism suited to turning. Twin-axis digital readout is fitted.

Model FAQs
Questions Engineers Ask About The DVT51
Is the DVT51’s speed range wide enough for mixed work?
The catalogued range is 6.3–200 / 5–160 / 3.2–100 / 3.2–100 / 2–63 r/min. The span matters more than the top figure: large diameters and tough materials live at the low end where torque does the work, while small-diameter finishing wants the top end. A range that covers both ends is what lets one machine carry mixed work.
What is built into the DVT51 that keeps it accurate?
Two build points matter most on this machine: servo feed motor with planetary reducer and ballscrew drive; and plc control in place of relay logic. 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.
How do I choose between the DVT51 and the DVT5225D-DVT5250D?
Both sit in the conventional vertical lathe 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 is a new DVT51 proven before it ships?
Every DVT51 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.
