①Plane general-purpose sanding process:
The main objects are flat parts, such as square lumber surface sanding, particle board, MDF, blockboard, laminated lumber plain board sanding and sanding after veneer, whether it is a square part, an ellipse or other shapes All parts can be flat sanded. If the surface of the part has high flatness and the sanding equipment has high precision, the paint film can be sanded. The wide belt sander is a typical equipment for flat universal sanding. It can complete the sanding task at one time and has high production efficiency.
②Professional surface sanding process:
The main objects are profiled parts, such as turned parts, decorative strips (such as lines processed by four-sided planing, press planing, lower shaft milling machines, or lines processed by linear surface), curved parts (such as solid wood curved parts, saw curved Parts), cylindrical parts (such as turning or milling parts), etc. Generally, professional machinery is used, such as a sanding machine for turning parts, a surface sanding machine for cylindrical parts, etc. The sanding tool used is sanding belt or grinding wheel, if sanding the surface with sanding belt, most of them need to be equipped with imitation briquette.
③Manual sanding process:
This method is suitable for sanding any parts, but considering the production efficiency and sanding quality, this method is often used for sanding parts with complex shapes, large volumes or not suitable for mechanical feeding, such as sponge sanding machines, oscillating sand Light machine, octagonal sander and brush sander, of which octagonal sander and brush sander are more suitable for sanding pattern carving parts. For boards with a certain thickness deviation and veneer, the sanding of a broadband sander can not fully meet the requirements of sanding, so a hand-pressed sander can also be used for supplementary sanding.
④Plane fixed-thickness sanding process:
It is mainly suitable for the sanding of solid wood parts and plain boards. Its purpose is to reduce thickness tolerances and ensure the processing quality of subsequent processes, such as ensuring the flatness of veneers and the flatness of paint.
⑤ Process combined sanding process:
Most of the parts processed by copy milling have complex shapes, and there is generally no corresponding sanding machine for sanding, and manual sanding is often used, so it is easy to cause deformation of the parts. Advanced copy milling adopts the synchronous processing of milling cutter and abrasive belt to complete the milling and sanding of parts. The parts processed by this equipment have smooth surface and high shape accuracy.
