Maximum precision in door frame closures. Say goodbye to forced fittings.
The GC3-SL is the milling machine designed to address one of the most common and insidious problems in the welding of profiles for fixtures: the accumulation of molten material beneath the seal. If left uncorrected, this defect leads to forcing and difficulties in fitting the glass, compromising the quality of the finished frame.
The GC3-SL allows for the quick and precise removal of excess material, both internal and external, ensuring clean and perfect surfaces for subsequent welding. Ideal for companies working with PVC profiles, with or without a central gasket, it guarantees a flawless leaf-to-frame closure.
The simultaneous processing of two pieces, millimetric mechanical adjustments, and maintenance-free high-frequency motors make this machine an essential tool for those seeking efficiency, precision, and zero rework.
5 reasons to choose GC3-SL
- Say goodbye to glass installation issues. Prevent the buildup of material under the seal that hardens and hinders the insertion of the glass.
- Perfect door closure on the frame. The precise milling ensures the correct fitting of the profiles, eliminating any gaps or misalignments.
- Maximum versatility. Suitable for profiles with a central seal, ensuring optimal sealing in every configuration.
- Zero maintenance for engines. High-frequency engines designed to operate without periodic servicing.
- Fast and repeatable processing. Precise mechanical adjustments and manual selectors for a quick and secure setup on profiles of various shapes.
