Different from the past grinding -HVOF grinding technology

图片
N ew materials often cause a domino effect on aerospace processing technology. Environmental problems have forced a change in materials from traditional chromium electroplating to HVOF spraying coating, which in turn affects the selection of grinding wheels and ultimately the selection of grinding machines themselves.   It swings between two lines The HVOF coating materials in aviation parts has had a positive impact on the aerospace industry. HVOF coating materials are not only more environmentally friendly but also more resistant to wear and tear and therefore last longer. During the migration, there is also a shift in the grinding process used to produce the parts. While resin-bonded diamond wheels are an old standard, vitrified bonded diamond wheels are now more popular because resin-bonded diamond wheels cannot be dressed in machines. This poses a challenge to maintaining consistency. By using a vitrified bonded diamond grinding wheel, one can use a rotary dresser and a rotar...

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...

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.
