Precision PVC end mill for windows

The PVC End Milling Machine (also known as UPVC Mullion End Miller / PVC Profile End Router) is a key auxiliary machine in plastic window and door production lines. It uses high-speed carbide milling cutters to machine flat ends, step surfaces, grooves, and tenons on PVC/UPVC profile ends — ensuring precise mullion-to-frame fit, watertight corners, and clean welds.

This machine features pneumatic clamping + pneumatic (or hydro-pneumatic) auto-feed, designed for single-operator batch processing with consistent milling depth and burr-free results.

Key Features

Engineered for PVC/UPVC — Cutter geometry optimized for polyvinyl chloride's low melting point; delivers clean edges without melting, tearing, or burrs

Auto Pneumatic Feed — Cutter head advances and retracts automatically; reduces operator effort by ~70% compared to manual push-type end mills

Quick Tool Change — Swap cutters or adjust spacers/collets to handle different profile cross-sections without machine modification

Adjustable Milling Angle — Positioning plate adjustable from -55° to +55° (or fixed 45° left/right optional) for angled mullions and square-cut applications

Dual-Axis Pneumatic Clamping — Vertical + horizontal pneumatic vices hold thin-wall profiles firmly without deformation or tool chatter

Multi-Profile Batch Milling — Wide worktable pressure plate clamps 3–6 mullions at once for doubled throughput

CE / ISO Available — Export models customizable for voltage (220V/380V/415V), plug type, and control language

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.
