LMD4000 Gantry Mill Machine

The PIINC LMD4000 Portable Gantry Milling Machine is designed for large-scale on-site machining and industrial equipment repair. Featuring two machining modes in one machine, it allows operators to switch between linear milling and gantry milling according to field conditions and machining requirements.

With an X-axis stroke of 4000 mm (157 in) and multiple Y-axis configuration options, the LMD4000 provides flexibility for machining large surfaces, seal grooves, and square flange surfaces. Its forged alloy structural steel beds, aluminum alloy arm, and rigid bed connection system combine structural strength with a portable design for demanding field machining applications.

The LMD4000 is suitable for maintenance and repair work involving compressor mounting bases, motor mounting bases, rolling mill arches, ship loaders, and mining machinery.

Key Features and Benefits

1. Two Machining Modes in One Machine

• Linear Milling Mode: Supports linear milling operations for on-site machining and repair.

• Gantry Milling Mode: Allows the machining width to be adjusted within the specified range to suit the workpiece and machining requirements.

• Switching between the two modes provides flexibility for different field conditions and machining tasks.

2. Rigid Bed Structure

• The machine beds are manufactured from forged alloy structural steel.

• A dedicated bed connection system helps provide rigidity during machining.

• The aluminum alloy arm contributes to the machine's portable design.

• The rigid construction is designed to support accurate machining across a range of industrial repair applications.

3. Precision X- and Y-Axis Guidance

• X-axis: Uses heavy-duty, high-precision linear guides and ball screws to support smooth, continuous movement while reducing friction.

• Y-axis: Features hardened dovetail ways with adjustable gibs. The precision-ground and hardened surfaces are designed to support machining accuracy and extend service life.

These guiding systems help provide controlled movement during linear and gantry milling operations.

4. Adjustable Gantry Milling Width

In gantry milling mode, the machining width can be adjusted within the specified range. This allows the LMD4000 to perform machining operations on surfaces, seal grooves, and square flange surfaces.

5. Convenient Installation and Leveling

The LMD4000 features a bed connection system designed to simplify on-site installation and alignment. The main bed is equipped with connection boards of different sizes and two connection plates on both sides. Jacking bolts and clamping bolts help operators install and level the machine efficiently.

The machine is designed for horizontal, vertical, or inverted installation, subject to appropriate mounting arrangements and site conditions.

6. Three-Output Hydraulic Power Unit

The LMD4000 is equipped with a hydraulic station featuring three power outputs to serve the machine's main movement and machining functions:

• X-axis feed

• Y-axis feed

• Milling spindle head

This three-output arrangement supports the machine's linear and gantry milling operations.
