550 CNC Ultra-Precision Internal Pivot Saw (45°/90°)

The 550 CNC Internal Swivel Precision Saw is an automated machine designed specifically for high-end door and window manufacturing. It is primarily used for high-precision cutting of aluminum alloy profiles and can meet complex processing requirements.

Featuring an integrally cast internal swivel structure that never deforms, the machine supports both 90° straight cuts and 45° inward miter cuts with a maximum cutting length of up to 4200mm, easily handling extra-long or special-profile workpieces.

Key Features

FAQ

Q: What is the difference between internal swivel and standard miter saws?

A: The internal swivel (inner swing) design tilts the cutting heads inward, allowing shorter material lengths to be cut without interference. This is especially useful for small-frame window and door components.

Q: Can the cutting angle be adjusted beyond 45° and 90°?

A: Standard configuration supports 45° and 90°. Custom angle options may be available upon request—please contact us for details.

Q: What materials can this machine cut?

A: It is designed for aluminum profiles, UPVC/PVC, and thermal break aluminum. For other materials, consult our technical team.

Q: Is the CNC system user-friendly for operators with limited experience?

A: Yes. The CNC interface features a straightforward menu system with preset cutting programs. Most operators can be trained within a day.

Q: What after-sales support do you provide?

A: We offer installation guidance, operation training, spare parts supply, and remote technical support. On-site service is available depending on location.
