A device for cutting a block of stone that includes a support bar including a monolithic metallic plate, and a number of fluid ports attached to the plate. The device also includes a wear bar that is secured to the monolithic metallic plate and a lower longitudinal slot, and a cutting belt positioned in the lower longitudinal slot of the wear bar and including a downward-facing cutting surface to cut the block of stone. A method of cutting the stone block is also disclosed.

An axially mounted non-circular hole saw device follows a lateral, oscillating cutting motion to cut a non-circular kerf in a workpiece. The device adapts to variously styled power tools. The device couples to a power tool at an axial orientation through a mounting portion. The axial disposition of the device relative to the power tool enables the axial vibratory force generated by the power tool to convert to a lateral, oscillating cutting motion followed by the device. This cutting motion forms a clean non-circular kerf, offsets vibrations during cutting, and minimizes debris formed during cutting. A cutting portion has a non-circular shape. The cutting portion includes a base edge and a teeth edge. A bridge traverses the base edge for stability. A mounting portion extends perpendicularly from the bridge portion. The mounting portion includes a gap defined by slots that couple to a coupling mechanism from the power tool.

Methods, wires, and apparatus for use in cutting (e.g., slicing) hard, brittle materials is provided. The wire can be a super-abrasive wire that includes a wire core and super-abrasive particles bonded to the wire core via a metal bonding layer. This wire, or another type of wire, can be used to slice workpieces useful for producing wafers. The workpieces can be aligned within a holder to produce wafers using the device and methods presently provided. The holder rotates about its central axis, which translates to workpieces moving in orbit around this axis. A single abrasive wire, or multiple turns of wire stretched tightly between wire guides, is then contacted with the rotating holder to slice the workpieces.

The present invention relates to an electrodeposited diamond wire saw using patterned non-conductive materials in which non-conductive materials are pre-patterned along the outer circumference of a wire on which diamond grit should not be rubbed, before the diamond grit is upset, in order to efficiently improve the manufacturing process, and to a method for manufacturing same. According to one preferred embodiment of the invention, the method for manufacturing an electrodeposited diamond wire saw includes: printing a masking solution on the outer circumference of a wire in a plurality of directions when the wire is inserted for patterning; and upsetting diamond grit on the remaining regions of the outer circumference of the wire, with the exception of the patterned region.

Tool bodies, tools and machines for operating the tool include electronic circuits for providing data, collecting data, analyzing data and for controlling machines based on such data. Tool bodies and tools may include electronic circuits having data collecting sensors, which may be embedded in a housing with the electronic circuit and/or positioned outside of such a housing. Sensors include temperature sensors, motion sensors, strain sensors, moisture sensors, electrical resistance sensors, position sensors, antennas, and other components.

A saw wire to cut hard and brittle materials is disclosed that comprises a steel wire that is provided with bends with segments in between. The average degree of bending of the bends is between 0.5% and 5%. Such a saw wire has a higher breaking load compared to saw wires having a conventional, higher average degree of bending. A method to measure the curvature is described as well as a process to make the inventive saw wire. The invention is applicable to any shaped saw wire for example a single crimped saw wire, a saw wire with at least two crimps in different planes, a saw wire with crimps rotating in a plane.

The present invention provides a linear saw, and a machining method and a numerical control machining device that use the linear saw. The linear saw includes a machining part, used for cutting a workpiece in a linear extension direction of the linear saw and forming a machined slot in the workpiece. The linear saw further includes a space-keeping part, which is disposed so that the entire linear saw does not contact the machined slot or is not subjected to an acting force from the machined slot when the space-keeping part passes through the machined slot. Because the linear saw has a space-keeping structure, the linear saw has time and space to recover from deformation produced after cutting a workpiece, thereby efficiently preventing an accumulated error and greatly improving position precision of a machined gap.

The present disclosure pertains generally to cutting belts, in particular cutting belts having a cable. In certain aspects, this disclosure provides new cutting segments and cable arrangements for cutting belts. In some embodiments, the cutting belt has cable arrangements that resist rotation when under tension. Cutting belts having cable segments positioned radially outward of other cable segments, relative to the central opening of the cutting belt, around at least 60% of the length of the cutting belt, and cutting belts having cable segments with different twist directions are disclosed.

A hole saw includes a base member configured to secure the hole saw to a drive device and a plurality of blade members where each blade member is connected to and disposed orthogonally to the base member via a respective extender. Each blade member has cutting teeth extending in a respective cutting direction and distances between the cutting teeth and the base member vary along the respective cutting direction of the respective blade members. Each respective extender is configured cantilever support opposite, freestanding distal ends of the respective blade member where each distal end of each respective blade member is disconnected from the distal end of an adjacent blade member.
