Used for finishing ceramic and resin binder diamond wheel. Principle 2 soft elastic soft elastic trim trimming method method method of trimming 2.1 soft elastic belt at the time set on the belt dressing wheel, diamond grinding wheel rotating at high speed trimming, reel slowly rotating, moving slowly on the belt pulley use of Plastic Base Grinding Wheel contact force belt and wheel combination effectively remove surface grit diamond wheel between so as to achieve the purpose of dressing.

Principle of diamond grinding wheel dressing law

  Has a good grinding performance on diamond cup grinding wheel industrial ceramics, carbide, optical glass, diamond tools and other difficult materials gem has a very wide range of applications. However, the presence of high hardness of diamond grinding wheel, trim rather difficult and prone to clogging and other issues in the dressing process, seriously affecting the quality and efficiency of the grinding surface dressing, limiting the application of diamond cutting wheels, a variety of diamond grinding wheel dressing article methods were compared and studied, analyzed the principles of various trim trimming methods, characteristics and use of the occasion. Dressing dressing grinding method is to use an ordinary abrasive grinding wheel and diamond grinding wheel, diamond abrasive grinding wheel rotary motion, while doing ordinary abrasive grinding wheel rotational movement also do feed movement, the role of the abrasive surface of the diamond wheel friction By slowly rotating, rotating metal bond while squeezing a certain pressure to crack the binder, with the continuous effect of friction, resulting in further expansion of the crack binder, binder eventually broken, so blunt diamond particles falling from the wheel surface, revealed sharp diamond particles so as to achieve the purpose of dressing.

How to choose a diamond polishing wheel speeds of different metal materials

Answer: According to the workpiece shape condition, can choose different widths and size of diamond single row cup wheel, diamond grinding wheel speed should be controlled within a certain range. Too high, diamond grinding wheel damage fast, life is short; too low, low productivity, diamond grinding cup wheel peripheral speed it must be appropriate. Metal material steel, steel, nickel, polished chrome at best peripheral speed is 18 ~ 30m / s, polished copper and its alloys, silver, zinc best peripheral speed is 14 ~ 18m / s, aluminum and its alloys , lead, tin and plastic optimum peripheral speed of grinding time should be 10 ~
 14m / s.

The whole process of diamond grinding wheel grinding

ANSWER: polished diamond grinding turbo cup wheel usually have coarse, medium and fine grinding mill three processes. Each transfer requires the use of a process are finer abrasive, and appropriate to reduce the rotational speed of the grinding wheel diamond polishing wheel, resulting in a more finely polished effect than the previous channel.

Specific steps polished diamond grinding wheel itself is subject to the workpiece surface roughness may be. In addition to aluminum material is severely scratched prints outside general machining parts are available l60 # shiny and polished, increasing 120 # kibble may be necessary prior to this time, and then the shiny, polished. Inappropriate, do not advocate a one-time ground with abrasive sand, otherwise only reduces efficiency, but also affect the life of the grinding wheel polished diamond continous rim cup wheel.

In order to improve the quality polished, while coarse machining time must be left rough machining marks mill to make way, the grinding time and must be left when roughing mill prints do, so workpiece surface finish and gradually improved improve, otherwise not only labor costs and material costs, the quality can not be guaranteed.

To avoid duplication of polished road marks, and improve the efficiency of grinding and polishing quality in every way polished diamond grinding cup wheel to wheel in the front channels are required to wear scar cross.

The problems of diamond grinding cup wheel

The question: What is the finish? To improve the surface quality of parts What is the significance?
