Abstract

The invention discloses a rotary floating cutting numerical control machine tool for a silicon rod, and relates to a numerical control machine tool, in particular to a numerical control cutting machine for cutting the silicon rod. The rotary floating cutting numerical control machine tool comprises a numerical control box, a machine tool body, a transmission mechanism, and a cutting mechanism and a silicon rod clamping mechanism which are arranged on the machine tool body, and is characterized in that the silicon rod clamping mechanism comprises a driving rotation support wheel which clamps the silicon rod in a matching manner in the vertical direction, and a floating rotary pressing wheel; the floating rotary pressing wheel is connected with an elastic pressing device which drives the floating rotary pressing wheel to tightly press the silicon rod; and the transmission mechanism is connected with a shaft of the driving rotation support wheel. The rotary floating cutting numerical control machine tool can realize the non-concentric axial rotation floating radius cutting of polycrystalline silicon rods which have the characteristics that the material texture density is sparse, workpieces are bent in the axial direction, ovality exists in the diameter direction, the diameters are different, the appearances are not irregular, the breaking phenomenon is easy to generate, and the like in the floating rotation state, and is novel and capable of realizing the automatic radius cutting.
