What is the role of wood sander
Sanding and grinding are agreed words, refers to some uneven, uneven thickness, do not meet the process requirements of materials and objects, through emery cloth, grinding wheel, sandpaper, cleaning cloth, non-woven polishing wheel and other physical removal, make it more smooth and flat, uniform thickness, a method of process to make it reach the standard. "Wood sander" Gu
Name meaning, is to complete the work of the woodworking machinery equipment used in sanding, mainly used for sanding the surface of wood workpiece to make some uneven, uneven thickness, do not meet the process requirements of the wood smooth smooth, uniform thickness in line with the requirements of further processing.
What kinds of wood sander
There are many types of woodworking sander. Different woodworking sander can be used according to different needs. What kinds of woodworking sander are there?
1. General classification
(1) Ordinary sander
Ordinary sander configuration power is small, the frame is relatively light, the model is small, the weight is light, the sand roller is small, the sand cutting force is relatively small, the overload operation is easy to cause damage, but the price is low, suitable for small-scale production.
(2) Heavy sander
Heavy sander configuration power is large, the frame is thick, the model is large, the sanding roll sand cutting force is large, strong and durable, but the price is about 30% higher than the ordinary type, suitable for large-scale production.
(3) overhead sander
Overhead sander is based on heavy sander, for the development and production of plate edge sander, table lifting height can be adjusted from 0-650MM range, customized machine lifting range can be more than 1 meter.
(4) double-sided sander
A one-time sander on both sides of the sander, the structure is more complex, inconvenient to adjust, the cost is relatively high, only large plate processing enterprises will use.
(5) primer sander
A sander that specializes in sanding primers.
Sort by style
(1) Roller sander
Roller sander is the emery cloth wound on the cylindrical surface of the roller, the parts for sanding. Machine tools can be divided into single-roll and multi-roll, manual feed and mechanical feed, single-sided and double-sided sanding, vertical and horizontal. Single roll is mainly used for thickness determination and rough sand processing of square and plate components below 400mm; Multi-roll is used for mass production, wide format (800 to 2500mm) of the board, plywood, plywood and plane frame thickness and fine sand.
(2) disk sander
Disk sander is to paste sandpaper on the grinding disk, through the rotation of the grinding disk to the workpiece surface or surface for sanding. According to the installation position of the grinding disc can be divided into single disc and double disc, vertical and horizontal, grinding tools on and under several. Usually only 30% of the diameter of the millstone is used in production, which is suitable for furniture and wood mold manufacturing. This kind of machine tool has low production efficiency and few applications.
(3) belt sander
Belt sander is the endless sand belt tensioned on two or more belt wheels. The rotation of the belt wheel makes the sand belt produce cutting motion to realize the processing of parts. According to the structural form, it can be divided into upper type and horizontal type, single sand belt and multi sand belt, manual feed and mechanical feed. A belt sander with a width of less than 400mm is a common belt sander. A belt sander with a width of more than 600mm is a broadband sander.
Broadband sander is a kind of efficient, highly white moving sanding equipment, widely used in large surface wood-based panel, panel furniture parts and solid wood sanding processing, can complete the fixed thickness sanding (that is to ensure the working thickness and ensure the workpiece surface finish). According to the structural form, there are also single sand belt, double sand belt, multi-sand belt; Sand belt above the table, sand belt under the table, or both sides; The feed mode also has caterpillar feed from the roller feed.
(4) brush type sander
Brush sander is a number of brushes and sandpaper staggered around the circumference of the cylinder, the other end of the sandpaper is wound on the sleeve. When the cylinder rotates at high speed, the sandpaper uses its own centrifugal force and the elastic force of the brush to press the workpiece table
The surface is sanded. Brush sander can be used to sand formed surfaces.
(5) Combined sander
It can be combined with roll type and disk type, disk type and belt type, and can also be turned, four sides
Planer, finishing planer and so on combined together, as fine sand and polishing processing of wood sander.
(6) Special-shaped sander
Generally for non-flat panel sander, 4 groups of sand rollers from 4 directions to the panel sanding, concave panel
Convex surface has a good sanding effect, can effectively replace artificial sanding.
