Embodiment Construction

[0041] Such as figure 2 As shown, the feature of this machine tool is that the workpiece 14 to be processed is fixed on the upper part of the machine tool, and the square-shaped cutting guide wheel assembly 10 wound with diamond wire 53 moves from the lower part to the upper part at a set speed to complete the cutting. A unique wiring scheme, the wiring and operation only need to be completed on the ground, without the need to go to the working platform, the surface of the mouth-shaped cutting guide wheel assembly 10 is coated with Out of the steel round drum 9 made of polyurethane material, multi-layer guide wheels 5, 6 which are inclined at a certain angle and arranged in upper and lower layers with the drum are adopted. The guide wheels 5, 6 arranged up and down can be 2-layer, 3-layer or 4-layer The structure can satisfy the operator to complete the wiring on the ground. The square-shaped cutting guide wheel assembly 10 stays at a height of about 1 meter to easily complet...

Abstract

The invention discloses a multiline cutting machine of numerical-control polysilicon silicon, and the silicon which is cut out is used for a reducing furnace used for producing large-diameter polysilicon through modified Siemens Method or silane method. The cutting method comprises the following steps: high-speed reciprocating motion or one-direction movement is carried out on workpieces by using electroplated diamond wires; the workpiece is pressed on a square or a rhombic wiremesh formed by crossing electroplated diamond wires; the workpiece is cut into lathy silicons. The workpiece is mounted on the top of the machine, and cutting can be realized by the bottom-up motion of a rectangle-shaped guide pulley subassembly which is wound with the diamond wires. In the invention, a unique routing scheme is utilized and routing and operation can be realized on ground without on a platform so as to reduce operational complexity greatly, improve work efficiency and safety. An ultrasonic transducer is arranged on the top of the workpiece to lead the workpiece to tremble lightly so that the cutting ability of the diamond wires is improved, cutout grain can be swept away rapidly by cooling water, and the processing speed is enhanced remarkably.

Description

technical field [0001] The invention relates to a diamond numerical control cutting machine tool in the field of silicon material processing, in particular to a numerical control machine tool using polysilicon cores for multi-wire cutting, which is used in the production of large-diameter polysilicon reduction furnaces produced by improved Siemens method or other similar methods The elongated silicon core used can be cut into a square or rhombus cross-sectional shape. Background technique [0002] At present, most of the current domestic polysilicon production processes are the conventional trichlorosilane hydrogen reduction method, that is, the improved Siemens method, the improved Siemens method or other similar methods. The main equipment for producing large-diameter polysilicon is the polysilicon reduction furnace. The long silicon core is powered on to heat the silicon core until the surface temperature reaches 1100 degrees Celsius, and high-purity trichlorosilane and h...
