Introduction:
Vitrified bond diamond grinding wheels possess pretty high abrasive resistance, especially in polishing hard and brittle workpiece. It has many advantages like high grinding efficiency, high grinding precision, excellent workpiece's surface grinding, etc

Application:
Especially for PCD tools rough, semi-fine and fine grinding.

Why use vitrified bond for grinding wheels?

图片
Compared with resin grinding, vitrified bond diamond grinding wheels have the following advantages: (1) The grinding efficiency of vitrified grinding wheels is high. (2) Large feeds can be used for vitrified grinding wheels. When the feed rate exceeds a certain amount, the resin grinding wheel will not be able to grind. (3) The vitrified bond diamond abrasive tool hardly needs to be trimmed when grinding, and the resin abrasive tool needs to be trimmed once in a period of time. (4) due to vitrified The shape retention of the grinding wheel is good, so the grinding accuracy is higher than that of the resin grinding wheel, so it has become the first choice for precision and ultra-precision machining.

How to make the abrasive tools that have been made soft down? The ceramic bond abrasive is immersed in a sodium hydroxide or potassium hydroxide solution, heated to the boiling point, and the concentration of the alkali solution and the boiling time are controlled to appropriately reduce the hardness of the abrasive. Refer to Table 1 for the compatible concentration boiling time.

How to determine the hardness of ceramic bonded diamond wheel grinding compound sheet? Wheel hardness refers to the external force of the grinding wheel surface particles from the grinding wheel surface is easy to fall off, binder control grinding ability and abrasive hardness has no relationship with the binder strength refers to the hardness of the grinding wheel.                                     www.moresuperhard.com                                     Email:Anna.wang@moresuperhard.com                                     Whatsapp:+8615617785923
