Can you sand veneer

The surfaces of furniture and handicrafts in life are smooth and beautiful. Their surfaces are usually veneered or painted, which gives the wood surface a very refined look. Before the veneer needs to be carefully sanded to avoid irreversible damage. But the veneer should not be sanded too much, and too much sanding may make it less effective. Before you start sanding, you should carefully inspect the veneer for damage - such as air bubbles, corners, or peeling, etc. Small repairs to these veneers can be done before sanding if you can. While hand sanding is suitable for thin and small applications. Industrial sanders are better for handling large veneers, including most furniture.

Sanding the wood before applying the veneer or varnish will ensure an even finish to the finish. Sanding can reduce unevenness or excessive holes, reducing factors that can affect the appearance or finished product. You can sand the wood with sandpaper or sanding equipment, but you must find a balance between over-sanding and under-sanding for best results. With the right tools and techniques, sanding your wood before application can be quick and easy.

General principles of sander design

(1) A variety of factors in the wood sanding process should be considered to ensure high processing accuracy and stable processing quality with process flexibility suitable for different workpiece processing and high adaptability to workpiece thickness tolerances.

(2) Convenient and comfortable operation, easy maintenance, repair and adjustment.

(3) Minimize vibration, dust and noise, improve machine tool and overall strength, and ensure its reliability and safety.

(4) Cost reduction, economical, durable, moderate power consumption and compressed air consumption.

(5) The structural layout and color tone should be harmonious to ensure the appearance quality.

(6) The geometric accuracy, working accuracy, manufacturing and acceptance conditions, and safety protection of the entire machine tool should meet the specified broadband sander standards.

Rack for sander

1. Vibration, noise, stiffness, reliability and other factors should be considered. For example, the entire welding frame beam of the double-sand double-sided wide-band sander is filled with expanded cement sand.

2. The whole equipment hoisting, transportation, leveling and fixing issues should be considered.

Sand rack design

According to different process requirements, the sander has three forms of sand racks:

(1) Sand-up type sand frame, the feeding system is below the abrasive belt, and the lifting and lowering of the feeding table is used to complete the sanding of workpieces of different thicknesses. Since the working height is not fixed, it is not conducive to the use of the production line.

(2) The lower sand type sand frame and feeding system are located above the sand belt. Due to the fixed working height, they can be used in the production line.

(3) The mixed sand frame is composed of an upper sand frame and a lower sand frame, which can complete the double-sided fixed-thickness sanding of the workpiece. It is generally designed as a heavy or semi-heavy sand frame. This kind of sand frame is mainly used for artificial board production line.

The design of the sand frame should mainly ensure its rigidity and seismic performance. The sand frame should be closely combined with the frame to make it a solid whole with the frame. Only when the above two conditions are met can the stability of the sanding process and excellent sanding quality be ensured.
