Four sided sanding
SP4 Multi-head sanders are designed for four-sided grinding and polishing of wooden and wood-based elements with a flat surface, of complex shape in panel elements, profiles, slats, door frames, etc.
The machines can be equipped with disc aggregates, vertical and horizontal grinding heads. At the exit, we can place four dust extraction heads to finally clean the workpiece. The number of grinding and cleaning heads is adjusted individually to the customer’s needs.
Machine shafts can be equipped with cartridges of a wide range of abrasives and cleaning brushes, allowing you to perform any finishing work from grinding to cleaning for specific production tasks. For example, when performing surface grinding and finishing works, after mechanical processing from grinding to polishing, between and after varnishing, watering, oiling, patination, leaching and other technologies.
The spindles have smooth speed regulation, additionally each spindle has concurrent and counter-rotating in relation to the direction of movement of the workpiece.
The workpiece is moved by a conveyor belt, which is equipped with a smooth speed control. Dust is removed through suction cups to individual extraction or to the company’s extraction network. The advances of the working brushes and the change of the height of the brushed elements are each individually regulated by manual drives.
The design of the working heads allows quick replacement of the grinding heads. In order to speed up and facilitate the organization of work, multi-head grinders can be equipped with infeed and receiving magazines. The simple design of multi-head grinders contributes to easy handling and reliable operation.
