02 Working Principle

Two cutter heads on one walking machine

The DMM-900X clamps onto the plate edge electrically and walks along it under its own feed drive, so plate length is not limited by a machine bed. Two Ø 80 mm cutter heads, each driven by its own 4 kW motor, work the edge together. The head tilts anywhere from 0° to 90°; each pass takes up to 35 mm of bevel width, and repeat passes build the bevel out to 80 mm at 37.5°. Close-pitch cutter heads carry standard CNC inserts, so each insert cuts lightly and replacement stays cheap. The reduction gearbox sits at the rear, which keeps the cutting side clear for narrow plate, and the control box is separate from the electrical cabinet.

03 Key Features

Built for the job site.

// 01

Dual Ø 80 mm cutter heads

Two cutter heads, each on its own 4 kW motor, cut the edge together — 8 kW of cutting power from a compact walking machine.

// 02

0° – 90° bevel angle

The head sets to any angle across the full quarter turn, from standard V and Y preps to steep bevels and square faces.

// 03

Up to 35 mm per pass, 80 mm in total

Each pass takes 1 – 35 mm of bevel width on 8 – 100 mm plate; repeat passes reach 80 mm of bevel width at 37.5°.

// 04

Rear-mounted gearbox, separate control box

With the reduction gearbox behind the machine the cutting side stays clear, so plate as narrow as 100 mm can be clamped and machined. Controls sit apart from the electrical cabinet for safer operation.

// 05

Close-pitch cutters with standard CNC inserts

A dense-tooth cutter head spreads the load so each insert cuts lightly and quickly, and standard CNC inserts keep running costs low.

// 06

Ra 3.2 – 6.3 μm, cold cut

Cold milling leaves a bevel face with no oxide layer and a finish that fully meets pressure-vessel welding requirements.

04 Industry Applications

Where this series earns its keep.

Hull and deck plate preparation

Bevel prep along long hull and deck plate edges, with the machine walking the edge instead of the plate moving through a stationary miller.

See hull and deck plate preparation solutions

Pressure vessel and structural plate

Wide-bevel prep on vessel shell plate and heavy structural sections up to 100 mm thick, at a finish that meets pressure-vessel welding requirements.

See pressure vessel and structural plate solutions

06 FAQ

Common questions about the DMM-900X.

Can't find your answer?

How wide a bevel can it cut?

Up to 35 mm of bevel width per pass. Repeat passes build the bevel out to 80 mm in total, reached at a 37.5° bevel angle.

How does it compare with the DMM-900?

Both are walking edge millers with a 0° – 90° head on 8 – 100 mm plate. The DMM-900X carries two Ø 80 mm cutter heads on 2 × 4 kW motors and takes up to 35 mm per pass, with a bevel width of up to 80 mm. The DMM-900 runs on 2 × 3 kW, takes up to 30 mm per pass and reaches 100 mm of bevel width.

How does it compare with the DMM-90X flip type?

Different problems. The DMM-90X flips its body to bevel both sides of the plate for X and K joints. The DMM-900X works one face of the edge with two cutter heads. Pick the 90X for double-sided geometry, the 900X for single-sided bevels.

What is the smallest plate it can machine?

Plate at least 100 mm wide and 300 mm long, from 8 mm to 100 mm thick. The plate is clamped electrically as standard.
