Wooden door sander is a machine tool for sanding and polishing the surface of parts and components with coated abrasives (sandpaper or belt). The sander can sand wooden components, particleboard, fiberboard, veneer, etc., and soften the finish of polyester paint. Sanding machines can not only process flat surfaces. It can also process the outer surface, the inner hole surface and various arcs; it is not only used extensively by people's woodwork factories, furniture factories, toy factories, but also used in vehicle factories and wooden mold workshops. The sanding machine has the characteristics of high processing efficiency, high finish and precision, and wide applicability. The double-sided sanding machine is one of the necessary equipment for wood products and factories.
According to the form and use method of sanding tools, generally divide the sanding machine into: sanding sander, disc sander, belt sander, brush sander, combined sander, etc. .
1. Roller sander: The roller sander is used to wind the abrasive cloth on the cylindrical surface of the roller to sand the parts. Machine tools can be divided into single-roller and multi-roller, profiled sander prices, manual feed and mechanical feed, single-sided sanding and double-sanding, vertical and horizontal. Single rolls are mostly used for the thickness and coarse sand processing of square materials and panel components below 400mm; multiple rolls are used for large-scale production. Where is a small shaped sander? Thickness and fine sand of plywood and plane frame plus.
Second, disc sander: The disc sander is a sanding machine that pastes sandpaper on the grinding disc and sands the workpiece surface or surface by the rotation of the grinding disc. According to the position of the grinding disc device, it can be divided into single and double discs, vertical and horizontal, and abrasive tools in Bu and Yiren. Generally, only 30% of the diameter of the grinding disc is used in production, which is suitable for furniture and wood mold manufacturing. Such machine tools have lower production efficiency and fewer applications.
(3) Belt-type sanding machine The belt-type sander is used to tension the endless belt on two or more belt wheels. The rotation of the belt belt causes the belt to cut and realize the processing of parts. According to the structure method, it can be divided into upper and horizontal, single and multiple belts, manual feed and mechanical feed. The belt width within 400mm is a general belt sander. Above 600mm is a broadband sander. Broadband sander is an efficient and highly dynamic sanding equipment. It is widely used in the sanding of large-scale wood-based panels, panel furniture parts and solid wood. Surface finish of the workpiece). According to the structure method, there are single belt, double belt, and multiple belts; the belt is above the workbench, the belt is below the workbench, or both sides are up and down; the feeding method also has the crawler feed from the roller.

(4) Brush-type sander: The brush-type sander intersperses several brushes and sandpaper on the circumference of the cylinder, and the other end of the sandpaper is wound on the sleeve. When the cylinder is reversed at high speed, the sandpaper uses its own centrifugal force and the brush's elastic force to press the surface of the workpiece for sanding. Brush sander can be used for sanding the appearance.
(5) Combined sanding machine: It can combine roller and disc, disc and belt, and can also be combined with turning, four-side planing, finishing planing, etc. for fine sanding and polishing.
(VI) Shaped sanding machine: Generally used for non-planar panel sanding machine, 4 sets of sanding rollers sand the panel from 4 directions, and have a good sanding effect on the uneven surface of the panel, which can effectively replace artificial sand Light.
