A wood fillet polishing device for furniture production

technical field

The invention relates to the technical field of furniture production equipment, in particular to a wood fillet polishing device for furniture production.

Background technique

Solid wood furniture is one of the types of furniture materials. Solid wood furniture refers to furniture made of natural wood. Furniture manufacturers generally paint solid wood furniture with varnish or matte paint to express the natural color of the wood. When pasting the strips, in order to meet the effect, several surfaces of the original wood need to be polished, so a polishing device is used to improve the brightness of the original wood.

But for some special raw wood, in order to improve the aesthetics, the corners of the raw wood are rounded so that the adjacent two sides form a circular arc transition, thereby improving the overall aesthetics. When setting the rounded corners, through the cutting equipment The corners of the original wood are cut, and then polished.
