Description

An annular diamond wire saw cutting machine

technical field

The invention belongs to the technical field of wire saw cutting, in particular to an annular diamond wire saw cutting machine.

Background technique

The 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 drive the diamond wire for high-speed motion, and at the same time, there is a relative linear motion between the workpiece and the diamond wire to realize the feeding movement to realize the cutting. The length of the diamond cutting wire participating in the cutting is the width of the workpiece in the cutting area. When the width is too large, the diamond cutting wire involved in the cutting is too long, resulting in the breaking of the cutting wire due to the excessive cutting force. Therefore, in order to reduce the cutting force, a lower feed speed is usually used, which affects the cutting efficiency.

Another cutting method is rotary cutting. The slow rotating motion of the workpiece makes the cutting line and the workpiece form a circle tangent to reduce the length of the cutting line involved in cutting. It is far away and the wire bow is large, which affects the cutting efficiency. At the same time, when the irregularly shaped cutting parts are rotated and cut, the whole cutting process is discontinuous due to the shape of the cutting parts. Sometimes the cutting line is in contact with the cutting part. The parts do not come into contact, so the cutting line will be impacted, causing the wire to break.
