Satin finishing machine
A satin finishing machine (also: brush machine , brush grinder ) is a special grinding and polishing machine and belongs to the group of electric grinders. The machines are available as handhelds as well as stationary machines in which the workpiece can be inserted. With the hand-held device, the device is brought to the workpiece and the surface is evenly ground, polished or deburred.
principle
Satin finishing machines work on a similar principle to grinding machines: A motor drives a grinding head via an axis or thread, which can be fitted with various attachments. Due to the tool, however, the process is brush-cutting . The brush attachment can be changed as required and enables different materials and workpieces to be processed. The speed is adjusted accordingly depending on the attachment and the material to be processed .
commitment
With satin finishing machines, various materials such as metals , non-ferrous metals , stainless steel , wood , glass, textiles, plastics can be ground, satinised, polished, cleaned, derusted or structured. Depending on the shape and type of workpiece to be processed, suitable attachments are used for the device. The brush attachments are made of nylon, wire, brass wire, sandpaper or rubber. Matting disks can also be attached.
With the mainly used satin finishing, a more even, lighter surface is achieved compared to sanding, which can be matt to matt glossy. Surface scratches and inclusions are removed, the surfaces are leveled or compacted. For example, the machines can be used to refine paper surfaces through compression.
Occupational safety
When working with burnishing machines, protective goggles and non-flammable cotton clothing must be worn. Safety shoes and work gloves are a useful addition. Because of the noise level, hearing protection is necessary for longer work .
When working with satin finishing machines, abrasion occurs . Many devices have a suction device that picks up flying parts and dust. Depending on the material, the proportion of dust and coarser abrasion particles varies.
During metalworking, glowing chips can be thrown away at high speed (flying sparks). If these glowing parts hit flammable material, there is a risk of fire. If the grinding sparks hit gaps or cavities in the work area, they can lead to hidden smoldering fires that only lead to flames hours later.
For stationary satin finishing machines used in trade, an annual safety check is required according to UVV in connection with the VDE regulations.
