definition
As used herein, word " comprises ", the modification of " having " and " comprising " is that be equal to and open legally.Therefore, except element, function, step or the restriction enumerated, other elements of not enumerating, function, step or restriction can also be arranged.
The specific embodiment
Referring to Fig. 1, show and be not in the mood for grinding machine 10.Be not in the mood for that grinding machine comprises resinoid bond emery wheel 12, regulating wheel 14 and for keeping the supporting member 16 of two PDC 18 between wheel.PDC comprises the polycrystalline diamond layer 20 that is bonded to tungsten carbide base material 22.PDC advances by the pitch angle alpha will between the axis of the speed controlled axis in resinoid bond emery wheel 12 at the grinding interface between two wheels and regulating wheel 14 and the rotary speed of regulating wheel.The resinoid bond emery wheel of prior art need to be used the carbonization silica to repair every now and then outer surface 26, to keep the ability of resinoid bond emery wheel grinding polycrystalline diamond layer.
The finishing of outer surface while in order to reduce or eliminate, grinding PDC, wish to make the performance of resinoid bond emery wheel to be similar to the emery wheel of Ceramic bond.This effect can realize in the following way: use high diamond concentration, and comprise that hard packing particle and soft packing particle are to control the damaged speed of resinoid bond abrasive wheel simultaneously.This resinoid bond emery wheel will be guaranteed to expose the new diamond particles in wheel, and reduce or eliminate the passivation (glazing) of use procedure outer surface simultaneously.The high concentration diamond partly can be the outer ring surface of emery wheel, part charge or the whole emery wheel of emery wheel.
Suitable diamond for abrasive wheel comprises for example natural diamond, diamond synthesis, resin bonding agent diamond, metal-bonded diamond, metal abrasives powder, aforesaid resinoid bond or ceramic bond diamond agglomerate, and aforementioned all combinations.In order to obtain the required hardness of resinoid bond abrasive wheel, diamond concentration is high.Especially, the diamond concentration as the percent by volume of the cumulative volume of the high concentration diamond of emery wheel part is 175% to 225% or 180% to 200%.Be less than 175% diamond concentration and can not reduce the needs of finishing, be greater than 225% concentration and become and be difficult to the integrality combination with enough.Can use or not use metal (as nickel or copper) coating diamond.If use the diamond of metal coating, coating weight percentage should be less than 40%, or is less than or equal to 30%.Excessive coating weight can be reduced to diamond concentration too low level, the finishing that can in use not produce the resinoid bond emery wheel of minimizing.If do not condense, adamantine size should be between 60/80 order size to 200/230 order size.At these more than limit and following scope can not provide required bulk density to obtain required diamond concentration.
Although that resin bonding agent diamond can be is suitable (if particularly agglomeration), diamond is preferably metal-bonded diamond.The common mistake of resin bonding agent diamond is weak and frangible and can't be for the resinoid bond emery wheel with grinding PDC.Can obtain intensity is the metal-bonded diamond of frangible (more weak) to more non-friable (stronger).This intensity grading is used different titles to describe by each supplier.In order more effectively to expose new diamond, preferred more weak metal-bonded diamond.For example, if use the diamond from ABC super hard abrasive company (ABC Superabrasives), intensity is a little less than ABS 2() strong to ABS 9() scope in grade.When using ABC super hard abrasive diamond, diamond is advantageously ABS 2 or ABS 3.Can obtain the worldwide super hard abrasive strength grade of WSG 200 to WSG 900.The diamond of proper strength can comprise WSG200, WSG300, WSG400 and WSG500.The LANDS super hard abrasive has the intensity that name is called LS200, LS230, LS250, LS260, LS270 and LS290.The diamond of proper strength can comprise LS200, LS230 and LS240.Usually, the adamantine strength range of the metal adhesive under 50% is suitable for given supplier.
