Background
An annular diamond wire saw cutting machine is a cutting device that uses an annular diamond wire as a cutting tool.
One of the cutting methods is to use a driving diamond wire to move at a high speed, and meanwhile, a relative linear motion is formed between a workpiece and the diamond wire to realize feeding motion to realize cutting, the length of the diamond cutting wire participating in cutting is the width of the workpiece in a cutting area, when the width of the workpiece is too large, the diamond cutting wire participating in cutting is too long, so that the cutting force is too large to cause the fracture of the cutting wire, and therefore, in order to reduce the cutting force, a lower feeding speed is usually adopted to influence the cutting efficiency.
The cutting method is also a rotary cutting method, the cutting line and the workpiece form a circle to be tangent by slow rotary motion of the workpiece, the length of the cutting line participating in cutting is reduced, but the cutting line participating in cutting is positioned in the middle of a guide wheel and is far away from the guide wheel, and the wire bow is large, so that the cutting efficiency is influenced, and meanwhile, when the rotary cutting is carried out on the cutting piece with an irregular shape, the whole cutting process is discontinuous due to the shape problem of the cutting piece, sometimes the cutting line is in contact with the cutting piece for cutting, and sometimes the cutting line is not in contact with the cutting piece, so that the cutting line is impacted, and the.
