High-precision knurling machine designed for the preparation of aluminum profiles in thermal break assembly lines.

General

The AS 221 GA is a specialized thermal brake rolling machine engineered to bond aluminum extrusions to polyamide strips through a controlled rolling process. Powered by a two-speed three-phase motor, this thermal brake assembly machine features a robust drive mechanism with eight motorized disc-carrying shafts that automatically adjust to minor profile deformations. The thermal brake rolling machine includes an eccentric correction system to rectify lateral distortion and vertical warpage during the bonding phase. Precise setup for this thermal brake assembly machine is managed through decimal position indicators and simultaneous horizontal and vertical movements, ensuring consistent shear strength for high-performance architectural applications.

Features

  • Two-speed motor configuration offering 0.7 kW to 1.1 kW (0.9 to 1.5 hp) for varied processing requirements.
  • Eight-shaft motorized drive system with automatic load adjustment for profile consistency.
  • Integrated eccentric system for profile warpage and lateral distortion correction of ±2 mm (±0.08").
  • Decimal position indicators for high-precision adjustment of assembly discs and guidance rollers.
  • Advanced guidance system with modular, anti-abrasive sliding rollers to support non-planar profile geometries.
  • Pneumatic shock absorbers on vertical guide rollers to detect and compensate for minute profile variations.
  • Power-assisted front safety guard and rear access door equipped with integrated safety locks.
  • Forward and backward bar control with reduced-speed reversing for operator safety.
