The invention relates to a method for cutting refractory metals, in which a solid body (1) made of a refractory metal is mechanically machining cut with a cutting apparatus (4, 7), wherein the cutting apparatus (4, 7) is wetted for cutting with a fluid (6) having at least 50 weight % water, wherein the cutting apparatus (4, 7) is brought to a positive electrical potential in relation to the solid body (1) during cutting. The invention also relates to a disc produced from a refractory metal using such a method, and such a disc that has an oxide layer with a thickness of between 2 nm and 1,000 nm on the cutting surface.

Provided are a method for machining a plate material by using a linear saw, and a numerical control saw machine apparatus. The numerical control saw machine apparatus includes: two carrying mechanisms, which are connected to two ends of a linear saw respectively; at least one control motor, configured for adjusting a distance between the two carrying mechanisms; and a pair of vibration motors, configured for driving the vibration of the linear saw, wherein, the distance between the two carrying mechanisms is adjusted by the control motor based on a monitored change in a torque of the control motor.

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.

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 base plate movably attached thereto. The frame base plate has a pivotable arm assembly and an arm wheel thereon which accept a cutting member. A visual tension indicator is operably connected to the frame base plate and the arm assembly and configured to indicate an amount of tension applied to the cutting member.
