1-6 Claims. I
This invention relates to methods and apparatus for the dressing of grinding wheels which are especially hard such as diamond grit wheels.
The primary object of this invention ,is to provide a method and apparatus ,jor the satisfactory dressing of diamond grit wheels.
Another object is 30. provide a method and apparatus for .crush dressing diamond grit wheels.
Still another obiect is to provirlea method and; apparatus ,for successively transierring configurations to harder ro'll members until .the final roll will satisfactorily crush dress a diamond grit wheel,
These and other objects and advantages bccome more apparent ,upon .rererence to the following specification taken together with the accompanying drawings in which:
Figure 1 is a perspective view illustrating the elements of a machine adapted for practicing themethodsof this invention;
ur s a s de e evati h win the whee in a grindin g p0$i'lii0n;
Figure 3 is a view similar to H3 36 2 "but showing the wheel being crush dressed;
u e-41 a. sjtio ta n. along th lin of Figure 1 showing the gluten employed when. the .wheel is. driven at low speeds; v
Figure 5 is, a section indicated by line 1-1.; on
Eigure 2 showing a configuration being transferred to an intermediate dressing roll, and
E gure '6 is a view taken along the line of; 5-18 on Figure '3 showing the diamond ,grit wheel in the processof "being crush dressed R fe rin t the. draw n s. It. indicates, th table for supporting a workpiece. f2 which is to be ground by a wheel M, the .wheel .and' table;
being relatively reciprocable.
"The wheel "I4 is carried on a shaft, Ni which; is adapted for being driven at grinding speeds bya motor 18. H5, through an over-running clutch "2'0, isra motor 22 which drives into the said shaft through re duction gearing.
the motor '18 is energized, the clutch at 20 'disengages the motor 22 from theshaft 1-6 and t'hef wheel may be driven at high surface speed.
a vitrified or resinous bonding compound.
Also-carriod'on'the barieer to mbracketjj; r isa roller 26 comprising pwdcles-of silicon caralso connected with the, sham when the motor 13 is dei energized-the motor '22 may be energized to drive the wheel I4 at reduced surface speeds. when bide which are preferably bonded together with a vitrified composition. While the wheel [4 having the diamond grit therein is too hard to be crush formed by a steel roller, the vitrified silicon carbide roller 26 is sufficiently hard to perform this operation. In turn, the roller 26 may be formed by bringing it into crushing engagement with a steel roller.
Such a steel roller is indicated at 28 and a means for supporting the roller 28 is shown at 30. The table 30 is slidable so as selectively to bring the roller 28 into crushing engagement with the roller 26. The roller 26 is freely mounted inits supporting bracket 24 while the roller 28 is adapted for being driven in rotation by a motor 30 workpiece l2, while the roller 28 is being urged 1 tion is, therefore, an important operation.
stated before, the diamond grit wheel may be crushed to shape by a vitrified silicon carbide roller.
either by turning or grinding or any desirable into engagement with the roller 26. After the roller 26 has been crush formed to the desired shape, the roller 28 and its support 3!! is retracted .to their Figure 3 position. Thereafter, when it is desired to dress the wheel l4, it may be moved into position over the roller 26 and driven at low speed by the motor 22 while being urged against the said roller. After the wheel has been dressed, a new grinding cycle may be instituted and, if
necessary, the roll 26 may again be trued by the wears slowly, substantially eliminates cracking and checking of the carbide tool tip and, because of its free-cutting action, generates very little heat in the tool being ground. The precise trueing of'a diamond grit wheel to a desired configuraroller and, in turn, the silicon carbide roller can be crushed to shape by a sufficiently hard steel The steel roller is, in its turn, formed combination thereof.
n Thus, by forming a first roller to a predeterf mined configuration "by ordinary machine mth ode and thereafter successivelytransferring that' able or necessary. In each case, however, the first roll would be machine worked to have the desired configuration on its surface, and the intermediate rollers and wheel finally to be dressed would be.
of a substance or composition capable of being shaped by the application of pressure.
It will be understood that various modifications and arrangements in structure could be made;
without departing from the spirit of my invention and, accordingly, I desire to comprehend such modifications and substitutions of equivalents as may be considered to come within the scope of the appended claims.
