How to solve the problems in the use of circular saw blade

Due to the competition factors, the process of supplier production materials is cut off and the material is cut to contain too much impurities. When the saw blade is cut to the material containing impurities, it will form a broken or cut out surface uneven.

The cutting vibration and the gap between the upper and lower parts of the saw blade will shake when the steel is not good in the production process, which will affect the cutting performance and cutting condition of the saw blade.

Cause analysis

The reason for the abnormal sound in sawing

1. No sharp or broken teeth

2. The workpiece clamp is not too tight

3. Chip attached to teeth

4. During cutting, the feeding frame is not allowed to bump and shake, and the machine table is not calibrated properly during assembly

5. Use of compression deformation saw blade

6. The deformation of the cut data is not standardized

7. Too fast cutting and incorrect number of teeth

Solution

1. Grinding saw blade from scratch

2. View workpiece clamping device

3. Stop cleaning, check whether the number of cutting teeth is suitable for cutting workpiece not straight and length inconsistent

4. Check the situation of the material rack and positioning ruler frequently, and correct the level of the machine

5. Because the saw blade has hammer, it is erected and set up to prevent gravity pressure

6. Selected raw materials and standard data

7. Select the correct cutting speed according to different data and select the number of teeth according to the thickness of the data

The reason of saw blade breakage or tooth breakage

1. The knife cover is not locked

2. Too blunt, too heavy to tear or rotate with workpiece

3. Saw blade tooth shape is incorrect and tooth number is not correct

4. Too much feed, too much overload

5. The workpiece is too sharp, thin and the raw material is too hard when the sawing is started

6. Speed too fast

Solution

1. Lock the screws

2. Grinding saw blade from scratch

3. Cut different data and different tooth shapes and teeth. If you can select a saw blade according to the requirements, you can not select a saw blade of any specification. Any data should be cut

4. Adjust the feed speed of cutting tool not too fast

5. Note to select the cutting method, special fixture shall be used to prevent data from shaking

6. Adjust the standard speed of the cut data
