The selection basis of the saw blade

Classification of material attributes according to sawing

Real wood: cut and cut vertically.

Crosscutting need to cut the wood fibre, aspect demand level off, can't have a knife, and there can be no burr, the saw blade used in the outer diameter of 10 or 12 inches and teeth should be 60 to 120 tooth, the thinner material using the more teeth machine accordingly. Feed speed also need to be slow. The number of teeth on the slitting saws is relatively small, feeding speed will be faster, so very tall to the requirement of chip removal, so the requirements of the saw blade diameter 10 or 12 inches teeth between 24 to 40 teeth, such as cutting tree bears more material need to use another with dovetail tooth saw blade.

Artificial board: density board, chipboard, plywood

When cutting, the cutting force should be considered and the problem of the cuttings should be considered, the size of 10 or 12 inches should be between 60 teeth and 96 teeth.

The use of two kinds of saw blades:

It is mainly used for solid wood crosscutting, slitting, decal plate and plastic etc.

It is mainly used for hard double plate, non-ferrous metal etc.

The basic data of the saw blade: the main spindle speed of the machine, the thickness of the workpiece, the size of the outside diameter and the diameter of the diameter of the blade. You can see these parameters on the saw.

Remember: the spindle speed must not exceed the maximum speed of the saw blade. This is a safety issue and must be guaranteed. (I've seen a lot of people using sawblades on vertical milling, and it's very dangerous to turn the blades on the top of the blade.

Selection basis: by main shaft revolutions and plans to match the saw blade diameter calculation, cutting speed, V = PI * diameter D * revolution N/(m/s) 60 reasonable cutting speed in 60-90 meters per second,

Specific Suggestions:

Material cutting speed

Cork 60-90 (meters per second)

Hardwood 50-70 (meters per second)

Chipboard, plywood 60-80 (m/s)

The cutting speed is too big, the machine tool vibrates big, the voice is big, the stability of the saw blade is reduced, the processing quality is decreased, the cutting speed is too small, the production efficiency is reduced. The same feeding speed increases the amount of cutting per tooth, affecting the quality of processing and the life of the blade saw. Because the blade diameter D and spindle speed N are power function relations, in practical application, reasonable increase speed, reduce saw blade diameter is the most economical.

The real quality ratio you need:

As the saying goes, "cheap goods, cheap goods, good goods are not cheap," may be true for other commodities, but not for tool tools. The key is to match. Factors such as cutting objects, quality requirements and personnel quality of the equipment. To make a comprehensive assessment, rationally choose the best use of the material, to save money, reduce costs, and participate in competition in the industry. This depends on the knowledge of the expertise and the information about the product.

2, correct use:

In order to make the saw play its best performance, it must be strictly regulated.

1, the saw blade of different specifications and USES, the Angle of the knife Angle and the base form of the design are different, as far as possible the use in the corresponding situation;

The size of the main shaft of the equipment and the size of the plywood and the position accuracy of the device have a great effect on the effect of the use, and check and adjust it before the saw. The effect of the clamping force on the clamping force of the splint and saw blade is eliminated.

3, the watch saw blade work situation, an exception occurs, such as vibration, noise, processing surface material, must stop adjustment in a timely manner, and promptly grinding to keep FengLi;

4, the sharpening saw blade must not change its original Angle, avoid the head of the knife local sudden hot quench, had better call professional grind

The blade of the blade should be suspended vertically to avoid long periods of flat, and should not be piled on top of it. The head of the knife should be protected from collision.
