Gantry machining centre
DLM-3020 Gantry Machining Centre
Built for the new energy vehicle industry and for aerospace, rail transportation and general machinery work on large aluminium alloy structural components.
Features
- The column and crossbeam are cast as a one-piece structure.
- High rigidity, large load-bearing bed base with the base and worktable cast as one.
- Lightweight moving components with high dynamic response.
- High-lead screws for high-speed displacement: X 30 m/min, Y 40 m/min, Z 24 m/min.
- High-speed, high-power electric spindle with BBT40 taper for better tool connection rigidity.
- Strong driving force and high acceleration — the X-axis is driven by dual servo motors.

Model FAQs
Questions Engineers Ask About The DLM-3020
What is built into the DLM-3020 that keeps it accurate?
Two build points matter most on this machine: the column and crossbeam are cast as a one-piece structure; and high rigidity, large load-bearing bed base with the base and worktable cast as one. 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 options are catalogued for the DLM-3020?
Catalogued options for the DLM-3020 include: FANUC 0i MF (3) or SINUMERIK 828D-280 control with high dynamic response; High-speed PLC engine for faster computation and high-speed machining. Options are named line by line on the quotation with the base configuration, so what is written is what arrives — and if an option does not earn its money on your parts, we will say so.
What work is the DLM-3020 typically bought for?
The catalogued work list for the DLM-3020 covers new energy vehicle, aerospace, rail transportation, aluminium processing. 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.
DLM-3020 or LM — which fits my work?
Both sit in the gantry machining 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.
What acceptance testing does the DLM-3020 go through?
Every DLM-3020 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.
