The working principle of tangent cutting of multi line cutting machine

      The cutting technology of multi wire cutting machine is to use a high-speed moving steel wire to drive the cutting blade attached to the steel wire to rub against hard and brittle materials such as semiconductors, thereby achieving the cutting effect. During the entire process, the steel wire is guided by more than ten wire wheels to form a wire mesh on the main roller, and the workpiece to be processed is fed through the rise and fall of the worktable, which can simultaneously cut hard and brittle materials such as semiconductors into hundreds of pieces. Compared with other technologies, multi wire cutting technology has the advantages of high efficiency, high production capacity, and high precision. It has gradually replaced traditional cutting techniques such as knife saw blades, grinding wheels, and inner circle cutting, and is currently widely used for cutting hard and brittle materials such as semiconductors.

Multi line cutting machine: can effectively improve production efficiency, improve product specifications, and increase product yield. It can reduce the cost of human resources and minimize material loss for enterprises. It can save the company's land area.

(1) Improper selection of electrical parameters and excessive current;

(2) Improper feed adjustment, intermittent fast and slow, frequent open and short circuits;

(3) Improper use of working fluid (such as incorrect use of ordinary machine tool emulsion), too thin emulsion, prolonged use, and too dirty;

(4) Pipeline blockage, significant decrease in working fluid flow rate;

(5) The conductive block has failed to make contact with the molybdenum wire or has been dented by the molybdenum wire, resulting in poor contact;

(6) When cutting thick parts, the interval is too small or a working fluid that is not suitable for cutting thick parts is used;

(7) The performance of the pulse power cutting diode deteriorates, and the negative wave is larger during processing, which increases the loss of molybdenum wire in a short period of time;

(8) Poor quality or improper storage of molybdenum wire can lead to oxidation, or improper tools such as small iron bars can be used to stretch the wire, causing damage to the wire;

(9) The slow speed of the wire storage drum causes the molybdenum wire to stay in the working area for too long;

(10) Improper selection of molybdenum wire diameter when cutting workpieces.

resolvent:

(1) Reduce the pulse width range, increase the intermittent range, or decrease the number of power transistors;

(2) Improve operational level, adjust feed rate appropriately, adjust feed potentiometer to ensure stable feed rate;

(3) Use specialized working fluid for wire cutting;

(4) Cleaning pipelines;

(5) Replace or move the conductive block to a different position;

(6) Choose appropriate intervals and use working fluid suitable for cutting thick parts;

(7) Replace the clipping diode;

(8) Replace the molybdenum wire and use a wire wheel to thread it;

(9) Reasonably choose the silk speed gear;
