Common problems and solutions of diamond saw blades

Diamond saw blade is a cutting tool, which is widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone materials, and ceramics. The diamond saw blade is mainly composed of two parts; the base body and the cutter head. The base body is the main support part of the bonded cutter head.

The cutter head is the part that cuts during use. The cutter head will be continuously consumed during use, but the matrix will not. The reason why the cutter head can cut is because it contains diamond, and diamond is the most important part. A hard substance that rubs and cuts the workpiece in the cutter head. The diamond particles are wrapped by metal inside the cutter head.

There are often some problems in the use of diamond saw blades. How to solve these problems?

1. The thickness of the cut sheet is uneven

(1) The basic tension is not suitable; the saw blade tension needs to be re-corrected.

(2) The screw of the fixed trolley screw bearing seat is loose; adjust the rotating screw.

(3) The diameter of the guide rail is poor in levelness; the suspected degree of disease detected by the method of pulling the wire is adjusted between 0.5mm, and the levelness should be less than 1mm.

(4) The clearance between the screw and the nut is large, and the operation does not eliminate the clearance; during operation, pay attention to eliminating the clearance in one direction.

(5) The phenomenon that the nut is not clamped tightly and shakes again; tighten the clamping nut.

(6) The guide pulley is inconsistent; loosen the nut and re-adjust the same.

(7) The end of the saw blade is too large; level the saw blade and pass the inspection.

(8) The welding of the cutter head and the base body is asymmetric; re-weld or replace the saw blade.

(9) The cut blocks are less than 0.5 cubic meters; the blocks should be larger than 0.5 cubic meters.

(10) The drive chain is too loose; adjust the chain tightness.

2. Excessive shaking during machine operation

(1) The main bearing clearance is too large; open the iron cover of the spindle box to adjust the nut.

(2) The spindle bearing is damaged, causing the saw blade to run erratically; disassemble the spindle box to check the spindle bearing and replace it with a new one.

(3) The radial runout of the saw blade is too large; check the radial runout of the saw blade and change the blade.

3. The height of the saw blade is inconsistent after use

(1) The clearance of the spindle bearing is too large; open the iron cover of the spindle box to adjust the nut.

(2) The accuracy of the diameter skipping the large center hole is out of tolerance; check and replace the saw blade.
