The present disclosure relates to an ingot slicing apparatus, including an ingot moving apparatus provided to be movable vertically and supply an ingot, a wire rotating apparatus provided to be movable horizontally to slice the ingot, a slurry supply unit provided to supply slurry to the slicing apparatus, and an air supply unit provided to supply air to the slicing apparatus and to adjust a supplying amount of the slurry supplied to the slicing apparatus.

A wire saw having a wire drive and a wire store for a saw wire, in which an actuating device for tautening the saw wire is arranged on a drive and storage unit of the wire saw. Also provided is a system made up of a wire saw and a remote control device, wherein the actuating device is a constituent of the remote control device. The invention relates to a method, and to the use of an actuating device for tautening a saw wire in a wire saw, wherein the actuating device is arranged on a drive and storage unit of the wire saw or is a constituent of a remote control device.

A cutting apparatus and the method of operating same is provided. The apparatus includes a feed tower assembly configured to be attached to an object and a frame assembly movably attached thereto. The frame assembly has arm assemblies thereon which accept a cutting member. At least one arm assembly can be pivoted relative to the other arm assembly and relative to the feed tower assembly. One arm assembly can further be moved relative to the other arm assembly and relative to the feed tower assembly in a vertical direction.

A cutting apparatus and the method of operating same is provided. The apparatus includes a feed tower assembly configured to be attached to an object and a frame assembly movably attached thereto. The frame assembly has arm assemblies thereon which accept a cutting member. A liquid spray system is provided for cooling components of the cutting apparatus.

The present disclosure relates to an ingot slicing apparatus, including an ingot moving apparatus provided to be movable vertically and supply an ingot, a wire rotating apparatus provided to be movable horizontally to slice the ingot, a slurry supply unit provided to supply slurry to the slicing apparatus, and an air supply unit provided to supply air to the slicing apparatus and to adjust a supplying amount of the slurry supplied to the slicing apparatus.

Monofilament metal saw wire for a wire saw, wherein the saw wire being provided with a plurality of crimps. The crimps are arranged in at least two different planes, such that, when measured, between measuring rods of a micrometer, over a length comprising crimps in at least two different planes, a circumscribed enveloping D diameter of the saw wire is between 1.05 and 1.50 times a diameter d of the saw wire itself.

A method and apparatus for forming a starter notch along the length of a work-piece for subsequent fatigue testing. The starter notch is formed with a cutting wire such that it will promote fatigue-cracking in the work-piece in one defined direction and avoids cracking in directions other than the length direction of the starter notch. Improved fatigue-testing analysis may therefore be realized.
