Two Heads Fast Feeding Veneer Polishing Sander

Purpose of Plywood Sanding

Sanding is also required before the plywood is veneered and painted to sand and polish any imperfections in the wood surface. These defects can affect the appearance and performance of finishes that are subsequently applied to the wood. These defects include scratches, indentations, burrs, small glue spots and uneven texture. But larger defects, such as large gouge marks and various forms of discoloration on the plywood surface, cannot be eliminated by the sanding process. The main purpose of the plywood sanding process is to use sandpaper to eliminate the defects of the plywood so that the surface of the wood is smooth enough, and the tiny scratches caused by sanding cannot be seen after the wood is finished, so as to facilitate the subsequent veneer and painting.

Two-head sander machine has sanding head and polishing head in the sanding machine. Sander can achieve sanding and polishing effect.

Veneer sanding and polishing

I believe that many people do not know the difference between sanding machines and polishing machines. Many people think that sanding machines are polishing machines. However, in some processes, a polishing process is required after the sheet is sanded, so there will be a sanding head and a polishing head in the sanding machine. In this way, the sheet only needs to buy this sander to complete the sanding and polishing process.

The difference working process between a sander and a polisher

Woodworking sanding machine refers to the physical removal of materials and objects that are uneven, uneven thickness, and do not meet the process requirements, through abrasive cloth, grinding wheel, sandpaper, scouring pad, non-woven polishing wheel, etc., to make them more smooth and flat. A method of uniform thickness and technology to make it meet the standard. "Woodworking sanding machine", as the name implies, is woodworking machinery and equipment used to complete sanding work. The thickness is uniform and consistent, which meets the requirements of further processing. Mainly for woodworking boards, floor and wall panels, bamboo and wood handicrafts, bamboo and wood toys, the specially developed sanding equipment has the characteristics of simple operation, high degree of automation, high production efficiency, mature and stable technology, and complete supporting facilities. It can be combined with automatic production lines. Perfect docking to form various automatic production lines.

Woodworking mechanical polishing machine

Woodworking mechanical polishing machine is mainly used for grinding and polishing of wood product blanks, specifically for various solid wood, composite boards, MDF and other furniture materials, and also suitable for linear wood lines and regular surfaces, special-shaped surfaces, Coarse and fine sanding, grinding and polishing of flat and curved surfaces.

Simply put, the sanding machine uses the cutting action of sand to smooth the processing marks, burrs, stains, etc. on the surface of the object.

The polishing machine uses polishing wax to fill the pits on the surface of the object to make the surface of the object more flat.

The polishing process generally follows the sanding process

Polishers, also known as grinders, are often used for mechanical grinding, polishing, and waxing. Its working principle is: the motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at a high speed. Because the polishing disc and the polishing agent work together and rub against the surface to be polished, the paint pollution, oxide layer and shallow marks can be removed. Purpose. The rotational speed of the polishing disc is generally 1500-3000 r/min, mostly infinitely variable, which can be adjusted at any time according to actual needs during construction.
