Single Crystal Diamond Tool Grinding Effects Of Factors

Diamond tool grinding method

Single crystal diamond tool manufacturing processes generally include material selection, orientation, sawing, cogging, installed cards, rough grinding, fine grinding and inspection. Will be selected by the original stone diamond orientation is along the plane after the cutting of open, get two blank tool, not only can improve the utilization of diamond material, but also reduce the total grinding capacity. Tool shape by opening up blank can install card (embedded or brazing) requirements. Cogging and coarse grinding of grinding methods are used.

Diamond grinding disc grinding process carried out in cast iron. Grinding disc diameter 300mm, organized by the materials the pore shape, size and proportion are optimized grinding diamond dedicated high-phosphorus cast iron. Platen surface-mount with diamond polishing powder, its particle size can be from less than 1 m up to 40 m. Coarse diamond powder has a high removal rate, but the ground of poor quality, so generally adopted a coarse meal, and fine grinding is used when the powder size of less than 1 m. Grinding before the first diamond powder and olive oil or other similar material mixed into a grinding paste, and then coating the surface of the grinding plate, place some time to fully penetrate abrasive grinding paste porosity in the cast iron plate, then a larger diamond pre-grinding disk surface grinding back and forth in order to further strengthen the diamond powder embedded in the cast iron pores in the role. Grinding, diamond grinding will generally be embedded in the tin bucket, only need to grind the surface exposed. Platen speed during grinding about 2500r/min, polishing pressure of about 1kg/mm2. Diamond grinding and other processing tool material is very different, the grinding mechanism has not been convincing interpretation of the factors that affect the grinding quality is multifaceted. Here on the diamond tool grinding some technology issues.

Grinding of the factors influencing

Experimental results show that conditions of grinding and grinding volume relationship

V = kvp

Type in the V?? Grinding volume

k?? grinding rate

v?? grinding speed

p?? polishing pressure

In addition, the diamond grinding, abrasive particle size, particle porosity in the cast iron elements in the mosaic state of grinding rate will also change the size, thus affecting the grinding capacity.

Grinding quality factors

Diamond hardness, brittleness, although the grinding tool surface roughness easier to guarantee, but prone to collapse mouth blade, serrated blade easily lower degree. Ultra-precision machining requirements of tool edge under the microscope at 500 times the population without collapsing, so need to optimize all aspects of the process of grinding to get the perfect straight edge.

Abrasive particle size and surface conditions on the grinding disc grinding Quality

Can be seen, as the impact of the meal on the large blade, serrated blade after grinding degree is also large, basically difficult to grind the blade out of the mouth without collapse; the use of powder when, after a few minutes of grinding the blade is changed after be straight, serrated degree tends to zero.

The new manufacturing process for precision grinding plate constraints, disk roughness greater stability for the ground to some extent. In addition, just coating the grit in the disk is also less of their own high. After a period of grinding, the disk is high on the research level, the larger abrasive particles have been broken or the shovel from the disk, so that the contour of abrasive improved degree of stability decreases serrated blade. Therefore, diamond tools for fine grinding the blade or the key processes, the grinding disc to be stable on disk.

As the abrasive grinding process will be constantly breaking or loss, if not in time be supplemented, will result in particle density due to insufficient disk Ershi diamond engagement directly with the iron will not only affect the quality of tool grinding, but also because of the crowded diamond scratch the role of damage or blockage of the disk's pores, thus reducing the service life of grinding disk. Therefore, in the grinding process needs to disk frequently to add new abrasive paste.

In addition, powder coating on the grinding plate disk before pretreatment is also essential, general Xu Yong Whetstone or coarse SiC abrasive powder on the disk to grind to remove turning grooves enhance the formation of disk. Through a variety of Whetstone and SiC powder with a grinding disk comparison test, was found with TL280ZY1 Whetstone 1 hour and then grind disk coated with fine diamond powder W1, get the best of the grinding disk, then disk to stabilize the shortest time, grinding jagged edge after the smallest degree. And use free of SiC abrasive powder can easily plug the pores of the disk, so that a large number of the diamond powder is difficult to firmly embedded in the grinding wheel.
