Definitions
- the present invention relates to a grinding method and a grinding machine for the grinding of at least one flat surface using at least one rotary grinding wheel.
- the invention relates to the field of planar grinding using an axial grinding wheel.
- the different concepts of this particular field, as well as the concepts of grinding in general, are best defined, at present, in the manual "Begriffe der Schleiftechnik” by Professor Dr. Ing. E. Salgié and Dipl.-Ing. H. Brandin, published by Editions Vulkan in Essen DE.
- the conical wheel can have a straight profile (integral rolling effect) or a slightly bevelled profile to obtain an angle of attack outside or inside the grinding wheel.
- the rolling effect is not integral over the entire generator of the dial, but the difference is negligible.
- the method and the device proposed by the invention allow continuous grinding without requiring any interruption to sharpen the grinding wheel.
- the proposed process is therefore particularly economical for planar grinding in large series of high precision.
- FIG. 1 shows the general construction of the machine. We will now describe this construction with reference to this fig. 1, the consideration of other figures, in particular of FIG. 2 will facilitate understanding of this construction.
- Machine 1 of fig. 1 includes a base 2 made of pieces of cast iron or steel and concrete. This base is extremely massive; the weight of the whole machine is around seven tonnes. Passages 3 in the base 2 allow the insertion of arms or other lifting means; the machine is transported using special conveyor means.
- the frame also includes a rising part 4, integral with a body with the base 2 and identically constituted by pieces of cast iron or steel and a mass of concrete. At the front a relatively thin wall 5, also made of ferrous material and concrete, rises to the working height of the machine.
- Two tank parts, respectively 6 and 7, are fixed to the left and right of the frame, with the front wall 5 and one face of the upright frame 4, these tank parts form a complete tank, in which the lubrication liquid is collected .
- FIG. 1 shows, for convenience of illustration, the grinding wheel 15, 16 in the raised position.
- FIG. 3 which also corresponds to FIGS. 1 and 2 and where the same reference signs are used, shows the machine in the working position, with a workpiece P fixed on the table 9.
- This fig. 3 makes it possible to understand what is the particular mode of cooperation of the wheel 17 and the abrasive ring 16. This operation will however be explained with the aid of the diagrammatic illustration of FIG. 4. On this one we mainly see the grinding wheel 15, with its abrasive ring 16, and the diamond wheel 17. A workpiece to be ground P rests on the table beam 8.
- the possible range of rotation is given by the length of the arcs 24.
- the rotation of the spacer 23 therefore acts in the manner of a reducer d 'angular deviation, a rotation of a few degrees of the spacer 23 causes a tilting (invisible to the eye) hundred times smaller (a few 0 / oo) of the axis of rotation of the grinding wheel.
- this adjustment, using the spacer 23, is an adjustment made once and for all at construction, to further refine the rigor of transverse perpendicularity.
- Figs. 1, 2, 9 and 10 clearly show how the device works, essential for this kind of grinding, for adjusting perpendicularities.
- the system adopted, with the false parallelism spacer 23, allows two adjustments perpendicular to each other while ensuring a very compact attachment.
- the lever 18 pivots relative to the beam-table 8 and that it comprises two obliquely milled parts for fixing the wheel and its motor.
- a pulley 48 an oblique axis 47 is driven in rotation, in a ball bearing holder block fixed against the oblique wall of the lever 18.
- the active part of the diamond wheel 17 is formed by a part. 49 which surrounds the bearing holder and which can be interchanged if necessary without the entire bearing device being dismantled.
- the motor 19 is similarly mounted against an oblique face of the lever 18 and it carries a pulley 50 connected by a belt to the pulley 48 of the thumb wheel.
- the tank part 7 (fig. 1) is widened on the right side.
