Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy cutting machine equipment, and in particular to a high-precision aluminum alloy cutting machine and a cutting method. Background Art

[0002] The cutting accuracy of ordinary aluminum profile cutting machines on the market mainly depends on the quality of the aluminum cutting saw blades used, as well as the assembly accuracy of the equipment. However, there are many uncertain factors in between, and the cutting accuracy cannot be controlled. Basically, the accuracy of this type of equipment will not be too high. The accuracy of ordinary fully automatic aluminum cutting machines can basically be controlled within ±10 wires at most.

[0003] A higher-precision aluminum profile cutting machine, similar to a separate aluminum cutting machine, has the advantage that the table will separate after cutting, automatically separating the saw blade and the material to prevent the saw blade from scratching the material again during the return process. This ensures the smoothness of the cut surface and the accuracy of the cutting. The precision of the separate aluminum profile cutting machine can basically be controlled within ±5 wires, with higher precision and higher cutting stability. However, among the factors that affect the cutting accuracy, whether the feeding mechanism can keep the workpiece in a better cutting posture can also affect the cutting accuracy. Therefore, those skilled in the art have proposed a solution of a high-precision aluminum alloy cutting machine and a cutting method for the current aluminum alloy cutting machine.
