摘要： A managing system for managing slurry, which is supplied to a wire saw. Slurry is prepared in a preparing tank and sent to the wire saw and used to cut workpieces. After usage for cutting workpieces, the slurry is sent to a separating apparatus from the wire saw. The separating apparatus separates impurities from the used slurry to recover a mixture of recyclable dispersing liquid and abrasive grains from the used slurry. The recovered mixture is returned to the preparing tank. The recovered mixture is mixed with fresh abrasive grains and dispersing liquid in the preparing tank to prepare slurry. The property (specific gravity and viscosity) of the slurry in the preparing tank is detected. The amount of fresh abrasive grains and dispersing liquid supplied to the preparing tank is adjusted in accordance with the detection results. Accordingly, slurry having properties that are optimal for the cutting of workpieces is prepared.

摘要： A workpiece 23 formed of a circular thin plate is rotated about its center as an axis L1. Each of disk-shaped rotating grinding wheels 27 and 28, while being rotated about an axis L3 extending in a direction substantially parallel to the plane of the workpiece 23 and perpendicular to the radial direction of the workpiece 23, is made to undergo relative feeding movement on both obverse and reverse surface sides of the workpiece 23 along an outer peripheral edge portion 23a of the workpiece 23. Consequently, the outer peripheral edge portion 23a of the workpiece 23 is ground by an outer peripheral surface of each of the rotating grinding wheels 27 and 28. In this case, it is preferred that two grinding wheels 27 and 28 for rough grinding and finish grinding be provided as the disk-shaped rotating grinding wheels, and that rough grinding and finish grinding are performed by the same station.

摘要： A workpiece receiving hole 60a for fittingly receiving a workpiece 17 is formed in the center of a rotary disk 60 which is thinner than the workpiece 17. A workpiece drive section 60b which engages a notch 17a formed for the purpose of orienting the workpiece 17 relative to crystal orientation is formed along the brim of the hole 60a. A gear 59 is rotated by a gear 62 of a motor 61, thereby rotating the rotary disk 60 and imparting torque to the workpiece 17. Accordingly, both surfaces of the workpiece are ground by means of a double disc surface grinder.
