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. Table 1    Alkali treatment to reduce the hardness of the abrasive reference table Abrasive Grit Boiling time （ h ） Original hardness of abrasive tool K L M N P Q R S T Y Alkaline concentration （ % ） 10 20 30 10 20 30 10 20 30 40 24# 124 123 234 234 113 123 223 123 234 345 235 46# 124 234 345 356 134 234 245 112 123 234 123 60# 124 123 234 346 123 234 235 112 123 233 133 The strength of the grinding wheel after the treatment will be reduced.

Single crystal diamond burnishing tool

图片
  The workpiece usually appears some tiny tool marks after machining. It requires one more step – “polishing” for reach superior surface finishing. However, this work slows down production efficiency a lot. “More Super Hard” launches a burnishing tool which is made of single crystal diamond now. The tools apply a certain pressure on the surface of workpiece, it generates plastic flow on the surface of workpiece, and then fill in the low through, that to achieve better surface finishing.   Single crystal diamond burnishing tool not only improves the corrosion resistance and surface quality of the workpiece, but also improves the machining efficiency.   1. The hardness of single crystal diamond burnishing can reach 10,000 HV, with the characteristics of strong wear resistance and low friction coefficient, it only takes a few seconds to process the surface of the processed workpiece to the required surface accuracy. 2. The efficiency of single crystal diamond burnishin...
