PVC End Milling Machine for Window Profiles

Key Features

• Profile end shaping: The PVC End Milling Machine for Window Profiles accommodates step faces, rectangular grooves, tenons and similar structures by changing tooling, which is secured on a horizontal spindle.
• Angled milling range: A positioning plate on the worktable can be set between -55° and +55°, enabling bevel cuts on profile ends without custom jigs.
• Linear bearing feed: The tool feed mechanism runs on a linear bearing motion pair, keeping vibration low and motion repeatable during milling cycles.
• End surface finish: Processed ends consistently reach Ra12.5 μm roughness, which is sufficient for tight assembly of transoms and frame sections.
• Pneumatic clamping: Profiles are held by air-operated clamps during the cut, reducing operator effort while maintaining workpiece position.

Technical Specifications

Application Scope

This PVC End Milling Machine for Window Profiles is used in the production of PVC windows, aluminum-plastic composite windows, and thermal-break aluminum window frames. Typical workpieces include middle transoms, door frame profiles, and other extruded sections that require end-face shaping, grooving, or tenon cutting before assembly.

Key Components

• Milling spindle: Horizontal spindle accepts interchangeable cutters for step, groove, and tenon work. Runs at a speed that matches carbide tooling for clean material removal.
• Linear bearing guide system: The feed carriage moves on sealed linear bearings, which require only periodic lubrication and help maintain consistent cut geometry over time.
• Pneumatic clamping unit: Clamps engage with 0.5–0.8 MPa air supply. Jaws are shaped to avoid marking profile surfaces during the milling cycle.
• Adjustable worktable: A manually set positioning plate allows the operator to dial in angles from -55° to +55°, with a scale for repeat positioning.
• Control circuit: Uses a simple push-button station and a safety interlock that prevents spindle start when the guard is open. Electrical components are arranged in a dust-sealed enclosure.

FAQ

Q1: What profile structures can the PVC End Milling Machine for Window Profiles process?

A: By changing the cutting tool, the machine mills step surfaces, rectangular grooves, tenons, and other end details commonly required on PVC and aluminum-plastic composite transoms and frame profiles.

Q2: What is the angular adjustment range for bevel cutting?

A: The worktable positioning plate is adjustable from -55° to 55°, making it possible to produce angled end cuts within this range without additional fixtures.

Q3: How is stability maintained during milling?

A: The tool feed mechanism uses a linear bearing motion pair, which reduces vibration and helps keep the milling depth consistent across repeated cycles.

Q4: What end surface roughness can be expected?

A: Consistently machined ends achieve a roughness of Ra12.5 μm, a finish that allows tight-fitting joints in window and door assembly.

Q5: What are the worktable dimensions?

A: The machine worktable measures 500 × 350 mm, providing stable support for standard UPVC and aluminum-plastic window profiles.

Q6: What is the maximum milling width?

A: The tooling set supports a maximum milling width of 90 mm.

Q7: What are the power and air supply requirements?

A: The machine runs on 380V, 50Hz three-phase power and requires a working air pressure of 0.5 to 0.8 MPa for the pneumatic clamping system.

Q8: Are spare parts available?

A: Yes. Common wear parts, including imported cutter wheels and setting tools, are available as options and can be replaced easily by the operator.
