In order to reduce the dressing time, there seems to be a temptation to choose a larger depth of repair. This is a very wrong idea. The cutting piece must be trimmed by selecting the most appropriate trimming depth. Choosing too large a refining depth results in high cutting temperatures, reduced dresser life, and the removal of useful cutting sheets. The ultimate result is that both the trimmer and the cutting blade are damaged, which is counterproductive. The optimum dressing amount is that after several repairs, it can restore the geometry of the cutting piece and just produce a good grinding edge. With a single-point dressing tool, the diameter of the fiber cutting disc Chinese supplier should be contacted with a 10-15o axial inclination angle. This will cause the single-point dressing tool to produce a sharpening effect when it is rotated periodically. A dressing tool with multiple points of contact does not need to tilt this angle. Instead, use the entire end face of the dressing tool to make contact with the surface of the cutting piece.

The lateral movement speed is the speed at which the dressing tool passes through the surface of the cut sheet during dressing. It plays a key role in the surface roughness and metal removal rate required for machined parts. The lateral movement speed is too slow, which will block the cutting piece and damage the surface roughness and metal cutting rate of the part. Too slow lateral movement speed can also cause the cutting piece to vibrate and burn the surface of the part. The even and fast lateral movement speed can trim the surface of the good cutting piece, improve the grinding performance of the cutting piece, increase the grinding efficiency and reduce the surface roughness of the part. > The cutting-edge CNC technology content is wonderful and worthy of attention.

Keep cool

Proper use of coolant can speed up dressing and improve finishing efficiency. As a rule of thumb, a 3/8-inch diameter coolant is used to remove a large amount of heat from the dresser and extend the life of the dresser. As the diamond dressing tool passes through the cutting blade, a coolant nozzle is installed to fill the entire surface of the cutting blade or to continuously fill the coolant to the diamond dressing tool. When the dressing tool comes into contact with the cutting piece and begins to be trimmed, the dressing tool is never allowed to exit and exit from the coolant. Otherwise, the diamond dressing tool will **** or **** under extreme cold and hot temperature changes.

High-precision filtration of the coolant using a filter prevents multiple cycles of dirt or chips in the coolant. The contaminated coolant can quickly wear the cutting piece and increase the number of times the cutting piece is trimmed. The dry cutting of the cutting piece is only carried out during dry grinding (only in this case the cooling of the diamond dressing tool can be interrupted). Before turning off the work every day, after turning off the coolant, let the cutting piece idle for a few minutes. This prevents the cutting piece from breaking.

Vibration is the enemy of trimming

In the trimming of the cutting piece, it is essential to effectively reduce the vibration, avoid leaving trim marks on the surface of the cutting piece, colliding and damaging the dressing tool, and the like. This means that the cutting piece balance must also be maintained, which is determined by the structural characteristics of the cutting piece itself. The uneven density and the geometry of the entire cutting piece will affect the inherent balance of a cutting piece. Therefore, it is also important to choose a high quality cutting piece. If it is a high-quality cutting piece, it can maintain a good balance of the cutting piece with proper installation. According to the manufacturer's instructions from the manufacturer of the cutting blade, the cutting blade is marked with an upward arrow indicating the light end orientation of the cutting piece after rough balancing. The user can then follow the arrows to pay attention to trimming the cutting piece to achieve dynamic balance. The coolant is evenly filled and sometimes helps the cutting piece to maintain balance.

In order to further avoid vibration, it is necessary to ensure that the dressing tool is firmly clamped on the holder and maintain a minimum amount of overhang to ensure sufficient rigidity of the dressing tool. If the diamond tool is not firmly clamped, it will cause vibration, noise, ripples on the surface of the part, strain the surface of the part and damage the dressing tool.

A superabrasive blade must be shaped and sharpened before it begins to grind. Following the experience presented in this article will help your cutting piece produce the most abrasive results.
