    摘要: A finishing grindstone member 20 is fixed to a spindle 10 by a bolt. In the spindle 10, there is formed a tool mounting portion 25 into which a rough grindstone member can be mounted. Into the tool mounting portion 25, there can be mounted not only the rough grindstone member but also a cover member 36. After a silicone wafer is roughly ground using the rough grindstone member, when finish grinding the silicone wafer using the finishing grindstone member 20, the cover member 36 is mounted onto the tool mounting portion 25 to thereby prevent the tool mounting portion 25 from being soiled.

    摘要: The wire saw includes a pair of reel bobbins (46,47). A strand of wire (37) is unwound from one of the reel bobbins (46,47) and wound about a plurality of cutting rollers (33,34), which constitute a cutting device (31). The wire is simultaneously wound about the other reel bobbin (47,46) while rotating the cutting rollers (33,34) to cause the wire (37) to travel. A cutting feed is applied to the wire (37) to cut the workpiece (30). The wire saw includes reel motors (48,49), which rotate the associated reel bobbins (46,47), a sensor (61,62), which detects the tension fluctuation of the wire (37), a compensating device, which alters the rotating speed of the reel motors (48,49) in correspondence with the detection data of the sensor (61,62). The wire saw further includes an altering device, which alters a compensation coefficient for altering the rotating speed of the reel motors (48,49) in correspondence with the winding diameter of the reel bobbins (46,47).

    摘要: In the wafer chamfering method, there is used a disk-shaped grindstone 8 which includes: a peripheral edge portion serving as a grinding surface 1; a flat portion formed in the central portion of the grinding surface 1 in the width direction thereof; and, two edge portions 5 respectively formed on the two sides of the flat portion 2 in the width direction thereof and made in the form of the shape of the valley portion of the notch portion 4 of a disk-shaped wafer 3 to be chamfered. In operation, in the wafer chamfering method, while rotating the above grindstone 8, the grindstone 8 is revolved in the thickness direction of the wafer 3 to thereby chamfer the wafer 3. Especially, the present wafer chamfering method comprises two steps: that is, a circumferential portion grinding step in which the grindstone is supported such that it stands upright or at right angles to the circumferential portion 6 of the wafer 3 at their respective mutual contact points and only the flat portion of the grindstone 8 is contacted with the mutual contact points to thereby chamfer the peripheral edge portion of the wafer 3; and, a notch portion grinding step in which the grindstone is supported such that it is inclined with respect to the diameter direction of the notch portion of the wafer 3 by an angle of about 45° in the circumferential direction of the wafer 3 and the edge portions 5 or both of the edge portions 5 and flat portion 2 are used to chamfer the notch portion 4 of the wafer 3.

    摘要: A spindle 23 of a grinding wheel 28 is rotatively borne by a bench 22 for the grinding wheel through hydrostatic thrust bearings 26 and 27. A pressure regulator 38 for regulating the pressure which must be supplied to at least either of supply ports 26a and 27a opposite to each other in the direction of the axial line of the spindle 23 in the hydrostatic thrust bearings 26 and 27 is provided. The pressure regulator 38 has a changing member for changing a passage for choking the fluid and the length of the choking passage.
