Pass-through centre SBZ 628

Versatile all-rounder for cost-effective and flexible non-stop profile machining – from blank bars to the finished product

 

  • Automation minimizes expensive handling and personnel costs
  • Compact, space-saving layout
  • No conversions thanks to the rotation module
  • Fast and precise thanks to the 360° rotating router spindle and the continuously adjustable pivoting saw
  • High process reliability thanks to the combination clamping system for on-the-fly and stationary machining
  • Continuous flow of products optimizes planning and productivity

 

The pass-through centre SBZ 628 for aluminium and PVC is designed for one-man operations and offers fully automatic machining of various profiles types with high precision and process reliability. Intelligent solutions such as a rotation module, a second X-axis for machining thick-walled profiles and a saw that can approach the profile from three sides make the SBZ 628 a powerful tool for metalworking and industrial companies who want less expensive, easier to plan and more flexible production.

 

Economic and strategic advantages

The pass-through centre takes care of all profile machining tasks securely, precisely and efficiently - from the infeed of the unmachined part to the finished product, with no manual intervention. By replacing several individual machining stations with one pass-though centre, companies can save on expensive handling and minimize personnel costs. However, the SBZ 628 has more to offer than simply increasing efficiency; it also provides strategic advantages. Through automation, users benefit from a consistently high quality and gain the ability to optimize their planning and react more flexibly during peak times.

 

Machining from every angle

The SBZ 628 can process vertical or horizontal profiles with cross-sections up to 320 x 160 mm. The rotation module is the machine's centrepiece. Equipped with up to eight drilling or cutting tools, it can move around the whole profile, machining all profile sides at any angle between 0 and 360 degrees. The powerful 6 kW spindle variant ensures speed and precision. On-the-fly changing saves even more time: as the current spindle finishes its machining task, the next spindle already starts up. The rotation module also operates at high speed: it can complete an entire rotation in less than two seconds.

 

Depending on the requirements and materials, the user can choose between on-the-fly or stationary machining. When machining lightweight, thin-walled profiles, the bar is moved via the pusher axis of the patented gripper system. For heavy duty machining tasks with long feed distances, such as thick-walled aluminium bars, the workpiece can be positioned via a second 400 mm X-axis. The rotation module then performs the machining tasks with the workpiece stationary on this axis.

Combination clamping system for safe and precise operation

In order to guarantee best-of-class results for both heavy duty stationary profiles and efficient on-the-fly machining, the combination clamping system reliably secures the workpiece from above and from the side. The servo-controlled tensioning block minimizes the clamp spacing, ensuring that less stable profiles also remain vibration-free. The clamping plates and tensioning rollers are equipped with a quick-change system and are height-adjustable, making it possible to easily secure complex profile geometries.

 

Continuously adjustable pivoting saw blade for three-sided length cutting

The 4-axis saw unit can be pivoted continuously to any angle between 0 and 360 degrees. The max. 650 mm saw blade can approach the profile from three sides and perform pull-back, plunge and notch cuts, for example. These machining tasks can be performed on both ends of the good part. Kerf spreading after sawing prevents re-cutting and ensures clean cut faces. The large saw blade diameter makes machining large profile geometries possible as well. This means that a profile with a width or height of 320 mm can be processed using the 650 mm saw blade. Swarf and residual pieces are transported out of the machine via the swarf conveyor belt.

Continuous production flow from infeed to outfeed

The automation already starts with the infeed of the profiles. The loading magazine holds up to ten 7.5 m or shorter profile bars. The conveyor belt transfers them to the patented gripper system. It features motorized rotation and horizontal as well as vertical adjustment, and automatically aligns itself based on the profile parameters. The gripper pushes the profile to the machining unit. A patent-pending moving clamp additionally secures the profiles from above and from the side, which is extremely helpful for precisely positioning heavy profiles or profiles with difficult geometries. Outfeed is handled by an external gripper, which already grips the good part during length cutting.
