Advantages &Features

01

The machine uses a carbide-tipped saw blade paired with a high-precision spindle, delivering stable rotation and consistently clean cutting surfaces across long production cycles.

02

A gas-liquid damping feed system ensures uniform, well-controlled blade movement, preventing vibration and helping maintain dimensional accuracy on thin-wall UPVC profiles.

03

Linear-guide feed motion provides high rigidity and repeatable positioning accuracy, supporting reliable operation even under continuous, high-throughput workloads.

04

Both cutting heads can automatically switch between 45° and 90°, enabling precise angle cutting without manual adjustments and improving throughput in window frame production.

05

The fully automatic protective cover opens and closes with each cycle, keeping operators safe while allowing unobstructed access for blade changes and routine inspection.

06

A high-lead ball screw drives the right head feed system, providing accurate transmission, smooth travel, and reliable positioning for large-section or multi-cavity UPVC profiles.

FAQ

Can the CNC Double-head Cutting Saw handle multi-chamber UPVC profiles without deformation?

Yes. The machine’s synchronized clamping and stable feed system are designed to support complex multi-chamber profiles, ensuring they remain rigid and undistorted during cutting.

How accurate is the length positioning during repetitive cutting?

With CNC control, linear guides, and a ball-screw feed mechanism, the machine maintains high repeatability across long runs, minimizing manual corrections and material waste.

What cutting angles are supported for UPVC window and door frames?

The two heads automatically adjust to 45° and 90°, which cover most frame and sash requirements in standard PVC window fabrication.

Does the CNC Double-head Cutting Saw require frequent blade changes?

The carbide saw blade and stable spindle rotation extend blade life, and most users only change blades based on production volume or after prolonged continuous operation.

What kind of maintenance does the feed system require?

Routine cleaning of the linear guides and regular lubrication of the ball screw keep the feed smooth and precise; no complex adjustments are normally required.

Is the cutting process safe for operators?

The machine integrates an automated protective cover, interlock protection, and stable damping feed, reducing exposure risk and ensuring safe operation during every cycle.
