Ultra-thin Diamond Cutting Wheel
2020-03-13Cutting hard alloy and zirconia ceramics are very challenging work, first of all, hard alloy often used as a tool, can see the hardness of the high, the same zirconia ceramics Mohr hardness of 8.5, monoclinic crystal density of 5.85, with a very high toughness and hardness, ordinary resin cutting pieces can not be processed.Learn More

CNC dressing technique
2020-03-09The CNC dressing technique can be used in all fields of grinding production, especially for small and medium production lot sizes and for prototype applications. The profile of the grinding wheel is created by the CNC controlled process that moves the rotating form roll along the target contour. Form rolls are therefore not restricted to a specific workpiece but can be used flexibly.Learn More

Honing technology principle
2020-03-06Honing can only change the shape accuracy of the processed workpiece. Some necessary measures should be taken to change the position accuracy of the part.If use the panel to improve the verticality of the end face of the part and the axis (the panel is installed on the stroke arm, adjust it to be perpendicular to the rotating spindle, the part can be processed by leaning on the panel).

The Features of CBN
2020-03-06The hardness of CBN is higher than that of ordinary abrasive. High hardness means stronger and sharper cutting ability; CBN has high wear resistance, meaning it is more difficult to wear than ordinary abrasives; The ability to maintain the shape of abrasive grains is one of the main characteristics of CBN as a high performance abrasive. CBN has a high compressive strength, which means it can keep particles intact and not easily broken when used in harsh conditions. CBN has good thermal conductivity and can realize cold cutting in grinding.Learn More

How to Dress Vitrified CBN wheels?
2020-03-04The dressing of CBN grinding wheel can be divided into two steps: Truing and Dressing. Truing is to make the grinding wheel reach the required geometric shape and dimensional accuracy by changing its macroscopic shape of the grinding wheel, and make the grinding wheel tip finely broken to form a sharp grinding edge; Dressing is to remove the binder between the grinding grains of the grinding wheel, so that the grinding grains protrude from the surface of the binder, forming the necessary chip space so that the grinding wheel has the best grinding capacity. According to the specific situation, shaping and sharpening can be unified or completed at the same time, also can be done step by step.

Selection of internal grinding wheels
2020-03-04When the internal grinding is performed in the inner hole, and if the diameter of the grinding wheel is too large, the contact arc between the grinding wheel and the work-piece increases. It increases the grinding heat and is difficult to cool and remove the debris. If the diameter of the grinding wheel is small, it is difficult to achieve the ideal grinding speed(30m/s-50m/s), making the grinding thickness increased, the load of the abrasive grains increased, and it is easy to be blunt, and the surface roughness of the inner hole is increased.

Several common types of diamond abrasive belts
2020-03-01With high efficiency, high life, high surface machining quality and environmental protection characteristics, diamond belt has been paid more and more attention in the field of hard and brittle metal materials precision machining, especially with the decrease of diamond price, its application field will be expanded gradually. There are a wide range of diamond abrasive belt products abroad, and there is a tendency to replace ordinary abrasive belts in the processing of hard and brittle materials and high-precision grinding.

Honing process and honing oilstone
2020-03-01Diamond honing oilstones generally use cold-pressing sintering or hot-pressing sintering. Cold pressing adopts metal mold, large forming pressure (400-500MPa), long mold life. Graphite mold is used for hot pressing, with low molding pressure (15-20MPa), low sintering temperature, small molding pressure, small loss of diamond strength, but large mold loss.

What Is Wheel Truing and Dressing?
2020-02-25Wheel truing is defined as act of restoring the cutting face of a grinding wheel by removing the abrasive material from the cutting face and sides of the wheel,so that it will run true with respect to the axis of rotation and produce perfect round or flat work.Learn More
