horizontalfor aluminummilling

Overview The SBZ 628 XL offers maximum flexibility for machining and length cutting of aluminium profiles used in metal construction and industrial applications. With configurable routing and sawing units, combination clamping systems and programmable grippers, the machine enables fully automatic processing of diverse profile types such as window, door and curtain-wall profiles.

Machining module Up to eight spindles can be applied flexibly to the profile cross-section and machine profiles at any combination of angles between 0° and 360°. Large opening dimensions and generous servo-travel ranges accommodate bigger cross-sections. Machining can be performed on the fly using a pusher X axis or while stationary with a second X axis for thicker walls. Plate clamps in the combination clamping system secure the profile; the roller tensioner reduces clamp spacing to improve routing quality. Front access to the machining area and HSK-C 40 tool holders allow fast tool changes.

Cutting unit The 4-axis saw unit (5.5 kW) has a travel range of 1,050 x 720 x 400 mm and enables separating cuts between 22.5° and 127.5°. Continuously adjustable pivoted cuts between 0° and 360° are possible. Various notching and separating strategies can be applied from three sides. Plate clamps allow narrow clamping spacing adjusted by servo drive. Table plates can be lowered to ensure unobstructed profile transport.

Profile outfeed with unloading magazine An external gripper places machined profiles gently onto the outfeed conveyor. The clamping system positions the external gripper during length cutting to ensure controlled transfer and defined withdrawal of good parts, including very short lengths. Guide rollers and clamping plates are adapted via quick-change systems for special profiles. Manual insertion mode supports machining and cutting of complex profiles with customized automation.

Infeed loading magazine For the SBZ 628 XL, five to ten profiles (1,500–7,600 mm) can be loaded depending on cross-section. Standard equipment includes five support swing arms and eight lifting rollers; up to nine support arms and lifting rollers are available. Residual pieces are processed fully automatically using the loading magazine and optional residual-piece measurement.

Gripper system The motorized gripper positions complex profile cross-sections precisely and rapidly using a linear servo drive. On the SBZ 628 XL, the gripper can be adjusted automatically in Y and Z and offers continuously adjustable 360° rotation based on profile parameters.

Profile clamping Roller tensioners secure the profile fully automatically and can travel along the entire bar length. They can be adjusted during machining to compensate for profile tolerances and clamp challenging geometries accurately.
