Plate Edge Milling Machine
Edge Milling, Chamfering, and Beveling for Steel, Stainless Steel, and Aluminum Plates.
What Is
Edge Milling Machine
An plate edge milling machine mills, chamfers, and bevels steel, stainless steel, and aluminum plates. Widely used in shipbuilding, bridges, pressure vessels, and steel structures, it enhances efficiency and precision.
Plate Edge Milling is a machining process that mills metal plate edges for a smooth, flat, or specific shape.
PEM plate edge milling machine delivers mirror-finish metallic surfaces with uniform edges. Advanced technology ensures perfectly parallel edges (±0.1mm tolerance), meeting strict welding standards.
Process of Plate Edge Milling
The Plate Edge Milling Process includes: securing the plate, selecting the milling cutter and setting machining parameters such as speed and feed rate; starting the equipment, with the milling cutter cutting along the plate edge to remove excess material and form the desired edge shape; and finally inspecting the edge quality to ensure it meets requirements.
Plate Edge Milling is a process used to machine the edges of metal plates, typically performed before welding to clean the edges, prepare bevels, and ensure dimensional accuracy. It effectively removes oxidation, rust, and burrs from the plate edges while creating suitable bevel shapes (such as V-type or U-type) for welding, thereby improving the quality and durability of welded joints.
The entire edge milling process with the PEM plate edge milling machine is often automated using CNC technology, enhancing efficiency and consistency, and providing high-quality edges for subsequent welding or assembly.
Type of PEM
Plate Edge Milling Machine
PEM-V & PEM-H: Only one side of the plate edge is the milling process, which is less efficient but less costly.
PEM-HD: Double-sided plate edge milling machine: Milling processes both sides of the plate edge simultaneously, with high efficiency, suitable for symmetrical bevel or high-precision requirements.
PEM-HF: Efficiently and accurately complete the bevel milling (such as welding grooves or chamfers) around the plate (such as steel plates, aluminum plates, etc.)
Features of PEM-V Plate Edge Milling Machine
While the PEM-HF plate edge milling machine enables complete edge preparation on all four sides of a plate (two long edges + two short edges) in a single loading operation, delivering high productivity with minimal tooling costs, cost considerations make the PEM-V single-side edge milling machine more common in the market. Below are its key features:
Key Components
Structural Components
Bottom base with rack & pinion mechanism for horizontal traverse of the vertical column along the T-slot bed
Vertical column with carriage to accommodate the milling head
Plate resting platform with optionally available self-powered roller conveyor (for automated plate loading, positioning, and retraction)
Clamping & Alignment System
In-built hydraulic cylinders for top-side plate clamping
Orientation cylinders to automatically set plates parallel
Edge Milling Unit & Adjustment Mechanisms
Side-mounted edge milling unit
Mechanical tilting facility (±45° spindle axis adjustment, Customized -45°, +60°) via bearing-supported worm & sector gear mechanism
Frame
Milling Units X & Y-axis Installation
PEM-J’s Milling Units are installed on the X(vertical column) & Y(bottom base)-axis of the edge milling machine, with the Y-axis being the base of the machine frame and the X-axis being suspended on heavy-duty guide rails. This ensures the stability of the machine during heavy-duty milling processes and improves processing accuracy.
PEM-J Plate Edge Milling Machine frame is rugged steel construction, machined after the welding for rigidity. Overall aging treatment effectively eliminates internal stress.
Open Gap Design
Edge Milling Longer than Stroke Length
Close-gap edge milling machine design limitation: milling plates longer than the machine’s stroke length remain impossible.
PEM-V Plate Edge Milling Machine designed with Reinforced Rigidity and Open Gap:
Box Structure Design
Precision Hydraulic Clamping
Consistent seam preparation for perfect weld
High fit accuracy ensures tight tolerances
Minimized vibrations for smoother operation
Reduced milling tip wear lowers maintenance costs
The heavy-duty box-welded construction of the press beam ensures vibration-free operation and high precision edge milling, even at maximum feed rates for consistent, high-quality results.
Built-in hydraulic cylinders provide safe, reliable plate clamping. Top-mounted clamping system ensures even pressure distribution, reduces maintenance while improving longevity.
High-quality
Gantry Edge Milling Unit
Decades-proven all-geared Edge Milling Units are engineered for heavy intermittent cutting, particularly in edge beveling operations. Milling speed is adjustable to meet specific requirements (210-611 rpm), with a multi-speed gear transmission ensuring optimal power delivery for demanding tasks.
The Gantry Edge Milling Unit of the PEM-V Plate Edge Milling Machine features a variable feed system for longitudinal and vertical axis movements. Cross-axis travel, primarily used for depth-of-cut adjustment, is manually operated with a fine-feed mechanism for precise control. The edge milling head offers ±45°(Customized -45°, +60°) tilt flexibility for versatile edge milling applications.
