DOUBLE-HEAD MITRE SAW

Double-Head Mitre Saw – Precision and Efficiency in Profile Cutting

Introduction: What is a Double-Head Mitre Saw?

A double-head mitre saw is a high-precision cutting machine designed for the processing of aluminium profiles, PVC profiles, and in some cases wooden profiles. Unlike a single-head mitre saw, the double-head version is equipped with two saw heads that can cut both ends of a profile simultaneously. This ensures exact cutting of window profiles, door profiles, and façade profiles in just one operation.

The term mitre refers to angled cuts, usually at 45° or 90°, which are essential for joining frame parts. With a double-head mitre saw, both straight cuts and angled cuts at different degrees can be executed with extreme precision.

Construction and Working Principle

A modern double-head mitre saw consists of the following main components:

• Two saw units (left and right), which can operate individually or simultaneously.

• A rigid machine base made of steel or cast iron to eliminate vibration and guarantee precision.

• Saw blades made of carbide or diamond-tipped materials, specifically designed for aluminium.

• Servo-driven axes for millimetre-accurate positioning.

• Protective hoods and safety systems to safeguard operators from chips and noise.

• Digital control unit (CNC or NC) for inputting cutting dimensions and angles.

Especially in window manufacturing with aluminium and PVC profiles, the double-head mitre saw has become indispensable due to its ability to deliver exact results with high productivity.

Application Areas of the Double-Head Mitre Saw

This machine is widely used in different industries:

• Window manufacturing – precise cutting of aluminium and PVC profiles for window frames.

• Door production – mitre cutting for door frames and constructions.

• Façade construction – cutting long aluminium profiles for curtain walls and glass façades.

• Industrial manufacturing – profile cutting for machine building and furniture production.

In particular, the aluminium profile industry depends on the double-head mitre saw, since aluminium bars are often several metres long and must be cut with absolute accuracy.

Advantages of a Double-Head Mitre Saw

Investing in a double-head mitre saw provides several advantages:

1. High precision – exact cuts, even with complex angles.

2. Time savings – cutting both ends simultaneously reduces processing time.

3. Flexibility – programmable angle ranges (from 30° to 135°).

4. Automation – CNC control enables batch production with minimal effort.

5. Durability – robust construction and long-lasting saw blades.

Compared to single-head mitre saws, the double-head model offers much higher efficiency and accuracy, particularly in industrial mass production.

Double-Head Mitre Saw in Window Manufacturing

In the window industry, the aluminium double-head mitre saw is considered standard equipment, as it allows a large number of identical profiles to be cut with high precision. Especially in PVC and aluminium window production, it is crucial that mitre cuts fit together perfectly. Even minor inaccuracies can cause gaps, leading to leaks or thermal losses.

With a double-head mitre saw, such problems are eliminated, and production quality reaches an industrial level.

CNC Technology in Double-Head Mitre Saws

The modern CNC double-head mitre saw is equipped with a fully automated control system. The operator inputs the required dimensions, and the machine automatically positions the saw heads and executes the cuts.

This provides:

• Faster series production

• Reduced waste thanks to precise cutting results

• Optimal material usage with intelligent cutting plans

Especially with the rising costs of raw materials, efficient use of aluminium profiles has become crucial. CNC double-head mitre saws excel in this field.

Key Purchase Criteria

When buying a double-head mitre saw, the following factors should be considered:

• Cutting length – which profile sizes can the machine handle?

• Angle range – how flexible is the saw for mitre cutting?

• Saw blade diameter – determines the maximum cutting height.

• Drive type – pneumatic or servo-driven.

• Automation level – manual, semi-automatic, or fully automatic.

• Price-performance ratio – balancing investment costs with production output.
