 Small diameter diamond saw blade can be used for cutting marble, granite, concrete, refractories, ceramics and other brittle materials. Cutting equipment is usually portable cutting machine, grinder, individual products is also useful to the desktop machines, such as tiles blade. Small diameter diamond saw blade according to the production process is generally divided into a green sheet and welding sheet. Sintered chip high production efficiency, the price is relatively cheap, but in the course prone to tip broken off, saw the matrix cracking, saw blade is not sharp and so on. Sintered blade can be divided into: minute tooth saw blade, continuous peripheral shape blades, turbine blade shape surrounding continuous blade, turbine blade tooth shape points. Welding laser welding sheet generally belong to high-end products. Laser welding saw expensive, expensive because expensive laser welding equipment, the matrix itself expensive, bit also need cold after sintering, sintering saw blade with respect to the production efficiency is low, but laser welding the blade tip and the substrate high strength, long life, broken, safety performance advantages not readily appear. Here I saw a small diameter matter in the course of noting that describe, for your reference.

       1, the operator should wear protective equipment related to former operations: such as safety shoes, safety glasses, hard hats, ear armor.

       2, cutting machines should have guards or other safety devices.

       3. Check the blade for damage before use, severe deformation, if damaged is strictly prohibited.

       Is there dirt on 4, check cutter chuck, when dirty to clean up after the installation, the spindle bearing or shaft sleeve for wear or severe, replacement of the bushings or equipment wear serious.

       5. When you install the blade must be made consistent with the direction of rotation of the cutter blade in the direction indicated. Direction of the cut does not move easily lead to inconsistent phenomenon.

       6, if it is wet cutting blade, add enough cooling water during use.

       Must be idle for a few seconds of time 7, using cutting blade if it is dry, dry cut every 10 to 15 seconds to cool the blade, for larger depths of cut should step cutting, dry cutting blade with water cooling cutting, the effect will be better.

       8, the cutting process can not curve cutting, grinding side allowed to use, and side curve cutting saw mill use is likely to cause cracking or breaking off the block matrix.

       9, if the cut is tilted cutting, cutting depth should not be too large, the cutting process must pay attention to safety, try not to let your body and the blade on a flat surface, the cutting process, hear abnormal sounds should stop cutting and Check that the blade is damaged, or check the blade mounting screws are loose.

      10, in the course of the event of blade jams, it becomes dull blade, or with a pottery wheel firebrick Re-open the blade (the blade is on the pottery wheel or ten bricks cut knife), re-open the blade can restore sharpness.

      11, when the cutting process encountered noise, vibration powerful, should be immediately stopped to check whether the blade has a crack or off the block, cracks and off the block, the need to replace the film.

      12, cutting saw blade cutting materials more than 2mm beyond the material being cut to reduce the extent of side bang.

      13, if the spindle blade aperture and cutting machines do not meet, can be coupled with the appropriate size of the washer, but during the cutting blade should pay attention to whether there is jitter, if any, will have to check the gasket off. If you continue to use the washer off, it can easily cause the saw blade when cutting jitter, resulting in loss of circular saw blades and can not continue to use. - Circular saw blade side of the head that is worn much less wear and tear on one side, you can see the different heads from the appearance of low degree of wear.
