CNC Double-Head Precision Cutting Saw for 45° & 90°

This Lebulang CNC double-head cutting saw for 45° and 90° cutting is a high-precision automatic cutting equipment independently developed and produced by Shandong Lebulang Precision Machinery Co., Ltd., tailored for aluminum alloy, PVC and plastic steel door and window profile processing. Adopting mature CNC numerical control system and integrated cast iron fuselage structure, the machine effectively reduces vibration during operation and maintains long-term running stability. It supports precise 45° oblique cutting and 90° straight cutting of various profiles, with a cutting angle error controlled within ±5′ and flatness of cutting surface ≤0.05mm. The whole machine features high automation, simple operation, low failure rate and easy daily maintenance, fully meeting the mass production and high-precision processing needs of door and window factories.

Feature And Application

Core Features:

- Intelligent CNC Control: The LBLCNC double-head cutting saw for 45° and 90° cutting is equipped with an advanced CNC intelligent system, supporting automatic positioning, fixed-length cutting and one-click 45°/90° angle switching, which effectively boosts overall production efficiency.

- High Precision & Stable Operation: Adopts imported servo drive system with fast response speed and ultra-high positioning accuracy. The integrated shock-absorbing fuselage structure prevents profile deformation and cutting burrs, ensuring smooth and flat cutting surfaces.

- Diversified Working Modes: Supports single-head independent operation and double-head synchronous cutting modes, featuring wide cutting range and strong compatibility to meet the processing demands of various door and window profiles.

- Energy-saving & Low Maintenance: Optimized structural design enables long-term continuous stable operation with low energy consumption and low failure rate, greatly reducing later maintenance costs for enterprises.

Application Scope

- Applicable Materials: Widely suitable for aluminum alloy profiles, PVC plastic steel profiles, architectural curtain wall profiles and various industrial aluminum profiles.

- Processing Functions: Professional for standard 45° splicing cutting of door and window frames and 90° right-angle fixed cutting of profile accessories.

- Applicable Scenarios: Ideal core equipment for standardized batch production and customized processing projects of medium and large door and window manufacturing factories.

Product Details

The Lebulang CNC double-head cutting saw for 45° and 90° cutting adopts high-precision integral casting process for the fuselage, which is not easy to deform after long-term high-intensity operation, effectively ensuring the consistency of cutting precision. The saw blade is made of high-hardness alloy material, with strong wear resistance and long service life, which can effectively avoid burrs and chipping during profile cutting. The human-machine interaction touch screen is simple and intuitive to operate, supporting parameter memory and batch programming, reducing the technical threshold for workers. Compared with ordinary cutting saws on the market, our equipment has more stable transmission performance, higher cutting precision and lower failure rate, and has passed strict factory quality inspection. All accessories are made of high-quality brand parts, with reliable quality and longer service life, helping customers reduce production costs and improve product qualification rate.

Key Features

1. CNC Precision Cutting – 45° & 90°

Both saw heads support quick-switch positioning for 45° mitre and 90° square cuts. Pneumatic angle locks ensure the heads stay firmly in position during the cutting cycle. Cutting accuracy: ±0.05 mm.

2. High-Performance Carbide Blades

Fitted with premium carbide-tipped circular saw blades (Ø500–550 mm, Ø30 mm bore), delivering clean, burr-free cuts on aluminum, UPVC, and thin-wall steel profiles. Automatic blade guard closing for operator safety.

3. CNC Servo Length Positioning

Servo-driven length stop system with ±0.02 mm repeatability. Operators input the cut length on the touchscreen — both heads auto-travel to the programmed position. No manual tape measure, no guesswork.

4. Pneumatic Clamping System

Dual vertical and horizontal pneumatic clamps on each head secure the profile firmly from all sides, preventing shifting and ensuring cut squareness. Clamping pressure is adjustable to suit delicate UPVC and thin aluminum sections.

5. Robust Machine Body

Heavy-duty welded steel frame with vibration-damping design. Rigid construction ensures long-term cutting stability and extends blade life even under continuous high-volume operation.

6. User-Friendly CNC Interface

7" color touchscreen with intuitive menu. Store up to 50 cutting programs with multi-length settings. Real-time monitoring: cut count, remaining pieces, blade hours, error diagnostics.

7. Clean & Safe Operation

Full-enclosure safety guards with transparent viewing windows. Automatic blade lubrication mist system reduces friction and heat. Chip collection drawer for easy maintenance. Emergency stop buttons at both ends.
