How to choose the right saw blade for TCT band saw blade grinding machine

 

 

According to the introduction of the TCT head saw blade production line, generally speaking, the more teeth, the more cutting edges per unit time, the better the cutting performance; but the more cutting teeth, the more cemented carbide is needed, and the higher the price of the saw blade; but If the saw teeth are too dense, the chip tolerance between the teeth will become smaller, which will easily cause the saw blade to heat up; there are too many saw teeth. If the feed is not properly matched, the cutting amount of each tooth is very small, which will increase the friction between the cutting edge and the workpiece and affect the service life of the cutting edge. Usually the tooth pitch is 15-25mm, and a reasonable number of teeth should be selected according to the sawing material. In theory, we hope that the thinner the saw blade, the better. Saw groove is actually a kind of consumption. The thickness of the saw blade is determined by the material of the saw blade and the manufacturing process of the saw blade. When choosing the thickness of the saw blade, the stability of the saw blade and the sawing material should be considered. The diameter of the saw blade is related to the sawing equipment used and the thickness of the sawing workpiece. The diameter of the saw blade is small, and the cutting speed is relatively low; the diameter of the aluminum cutting saw blade is large, which requires high saw blades and sawing equipment, and the cutting efficiency is also high.

 

Phenomenon of grinding head feeding sliding plate of TCT band saw blade gear grinding machine

The wheel carriage can feed in a straight direction. The gear to be ground is supported by the indexing frame and the tailstock, and reciprocates longitudinally through the worktable to grind the tooth surface. Indexing is performed after each tooth is ground. On the machine tool for grinding helical gears, the grinding wheel can be rotated to a point of view according to the helix angle of the workpiece, and the workpiece can be additionally transformed in reciprocating motion.

 

If the grinding wheel carriage of the machine tool can make the grinding wheel enter the internal gear workpiece, the internal gear can be ground. The profiled grinding wheel gear grinder has a simple layout, high efficiency, and the accuracy can reach 5 grades. It is suitable for mass production. The grinding wheel of the profiled grinding wheel gear grinding machine processed by the forming method is shaped into a tooth shape in the axial section by the profiled grinding wheel dresser. It is especially suitable for gears with a small number of teeth. The speed of the feed slide of the grinding head of the saw blade grinding machine is uneven or there is an impact phenomenon, and the hydraulic speed control valve is faulty. Remove the speed control valve for cleaning or replacement. The solenoid valve is out of order, remove it for cleaning or replace it. The rails are improperly parallel, loosen the adjusting screw and readjust.

 

The unbalanced angular velocity of the automatic saw blade grinding machine is that the angular velocity is too low or the angular force is too fast, which causes the angular swing to make a huge impact. The pressure of the positioning cylinder is too large, and the throttle valve should be adjusted. The set flow rate of the left and right swing angle throttle valve is not appropriate, and the throttle valve should be adjusted.
