Milling wheel

from Wikipedia, the free encyclopedia

The milling wheel , also known as a scraper wheel , is a tool for plaster milling or floor milling , which is used to remove plaster in the wall area, but also to remove paint coatings or adhesive residues. Depending on the area of ​​application, the milling wheel either consists of a steel blank with hard metal tips soldered to the tooth tips , or it is completely sintered from hard metal . In recent years, milling wheels made entirely of hard metal have become the norm, especially for cleaning milling.

Structure of a tool equipped with milling wheels

A tool head for milling wheels usually has three to twelve running axes equipped with milling wheels. The strength of the running axles is such that the milling wheels sit loosely on them with a few millimeters of play. The milling wheels describe a circular path through the tool head during operation.

In a simple classification there are three types of milling wheels:

Pointed tooth shape

The most common form; develop a force acting vertically on the ground. Suitable for removing plaster and tile adhesives or even thin paint coatings. Due to the dust created on the subsurface, the classic milling cutters kept sticking to the running axis. This problem was recognized by the manufacturers and led to the development of milling cutters with so-called dust outlet openings. These are implemented using spacer elements placed on one or both sides.

Inclined tooth shape

Develop a force acting at an angle on the ground. Suitable for removing non-load-bearing leveling compounds and very coarse, brittle plaster.
