How much does a wire cutting machine cost?

As of January 2020, wire cutting prices range from 20,000 to 900,000.

1. Slow wire cutting: the price is about RMB 400,000 to RMB 900,000.

2. Medium wire cutting: The price is about RMB 50,000 to 150,000 RMB. Anything lower than this price cannot be called medium wire cutting at all.

3. Fast wire cutting: The price of Ningbo machine 32 is about 20,000 yuan, and the price of Taizhou machine is generally between 25,000 and 35,000 yuan.

The mechanical part of the wire cutting machine tool is the foundation, and its accuracy directly affects the working accuracy of the machine tool, and also affects the full play of the electrical performance. The mechanical system consists of machine tool bed, coordinate workbench, wire transport mechanism, wire frame mechanism, taper mechanism, lubrication system, etc.

The machine tool bed is usually a box structure, which provides a mounting platform for various components and is closely related to the accuracy of the machine tool. The coordinate worktable usually consists of a cross carriage, rolling guide rail, screw kinematic pair, gear transmission mechanism and other parts.

Physical principles

Free positive ions and electrons accumulate in the field and quickly form an ionized conductive channel. At this stage, an electric current is established between the two plates. This leads to countless collisions between particles, forming a plasma zone, which quickly rises to a high temperature of 8,000 to 12,000 degrees, instantly melting some materials on the surfaces of the two conductors.

At the same time, due to the vaporization of the electrode and the dielectric fluid, a bubble is formed, and its pressure rises regularly until it is very high. Then the current is interrupted and the temperature suddenly drops, causing the bubble to explode inward, and the generated power throws the molten material out of the crater. Then the corroded material re-condenses into small spheres in the dielectric fluid and is drained away by the dielectric fluid.

Then through NC control monitoring and control, the servo mechanism is executed to make this discharge phenomenon uniform.
