Test tool specifications:  integral HM twist drill D10.1*61*103*SD10.

CNC tool grinder is widely used, how to choose the right grinding wheel to get a good grinding effect? The commonly used resin bond grinding wheel and metal bond grinding wheel and hybrid bond grinding wheel are used for cutting tool grooving.

CIOE 2021 (The 23rd China International Optoelectronic Exposition), as the world’s leading optoelectronic exhibition, will be held at Shenzhen World Exhibition & Convention Center on  September 16-18, 2021. The exhibition focuses on precision optics,chip materials,infrared materials and components and other fields.

When use silicon carbide grinding wheel or other mixed-abrasive grinding wheels based on green silicon carbide for titanium alloy, the grinding wheel adheres to titanium alloy seriously, which leads to large grinding force and poor processing quality.

Thermal spraying does not mean that how thick can be sprayed, the thicker the thickness, the more difficult the spraying, because it is to be sprayed on the spraying surface again, the sprayed particles are not easy to adhere to it, resulting in loss of waste, so the cost will increase exponentially.The spray thickness is generally 40 wires.

Diameter of the grinding wheel is too large, the contact arc between the grinding wheel and the workpiece will increase, which will increase the grinding heat and make cooling and row cutting difficult. If the diameter of the grinding wheel is too small, it is difficult to achieve the ideal grinding speed (30m/s~50m/s), which increases the grinding thickness, increases the conformity of the grinding grains, and is easy to blunt, which increases the surface roughness of the inner hole and reduces the production efficiency when grinding the hole of workpiece.

At present, most of the wafer cutting is using high precision scribing machine, which is mainly mechanical processing.

Under the action of mechanical stress, the wafer is prone to quality abnormalities after cutting. Common quality abnormalities include: product surface, back Chipping, PAD oxidation, delamination, missing Angle and other abnormalities.

Electroplated diamond grinding head is widely used in optical lens, prism, watch glass and sapphire glass. Through the processing of various workpiece, in order to achieve the effect of grinding, fitting, polishing.
