Precision Cutting Wheel

  Processing with

A Type of precision processing method where a cutting wheel spinning at high speed is used to grind the material being processed via the extremely hard particles (abrasive grains) which the wheel consists of. The material can be gently processed without being damaged, while the superior precision cutting realizes a finely finished surface.


  1. Utilizes extremely hard mineral grains and hence, in addition to ordinal metal material and hard brittle materials such as hardened steel and cemented carbide/ceramics can be cut.
  2. Excellent finish and superior size precision are realized by the extremely fine grinding process.
  3. The cutting speed is extremely high, thus making the overall cutting efficiency (volume of chips ground per hour) high even though the size of the chips is very small


The body of the cutting wheel, as revealed by the illustration on the left, consists of 3 elements: abrasive grain, bonding agent, and air hole. The large number of abrasive grains on the working surface grinds the material away little by little because of their roughness. The abrasive grains gradually dull, get crushed, and eventually come away from the working surface. However, as grains fall off new abrasive grains sequentially appear on the surface. This means that the edge of the wheel remains at the end, although the external diameter does decrease in size.

■ Labeling and Characteristics of Cutting  

■ Abrasive Grains 

We have the following types of abrasive grain available, which depends on the material to be processed.

■ Grain Size 

The grain size denotes the size of the abrasive grains used, with #80 through to #600 being available. The size of the grain and degree of the bond decide the roughness of the finished surface of the material to be processed.

■ Degree of Bond (Hardness of cutting wheel move) 

The degree of the bond denotes the strength of the bonding agent to the abrasive grains. The degree range from A to Z, with the range we have available ranging from H to R. The degree of the bond is the weakest (softest) with A and the strongest (hardest) with Z. The degree of the bond affects its abrasive qualities, and hence the cutting effect of the cutting wheel, and therefore is the second most important factor after the abrasive grains themselves. A weak (soft) bond means that the wheel cuts sell but wears out relatively quickly. A strong (hard) bonding means that not many abrasive grains so come off and hence the cutting speed decreases as their roughness becomes dull. It therefore has less cutting capabilities but is quite durable.
