Numerical control two-face grinding machine for high speed steel circular saw blade

Abstract

The invention relates to a numerical control two-face grinding machine for a high speed steel circular saw blade. The numerical control two-face grinding machine for the high speed steel circular saw blade can machine the two end faces of a workpiece at the same time. The numerical control two-face grinding machine for the high speed steel circular saw blade comprises a machine frame and is characterized in that the machine frame is of a T-shaped structure, two sets of grinding wheels are arranged in the middle of the machine frame in parallel, servo motors for driving the grinding wheels to act are arranged outside the two sets of grinding wheels correspondingly, a tool for clamping the workpiece is arranged in the middle of the machine frame in the vertical direction, both the tool and a control system of the two sets of grinding wheels are connected with a PLC numerical control system. The numerical control two-face grinding machine has the beneficial effects that inverted two-face grinding with numerical control two-face grinding heads is adopted, so that deformation is avoided during workpiece machining, and adverse influences of deformation on machining quality are avoided; and meanwhile, two-face grinding is carried out on the workpiece, the efficiency is improved, and the workpiece quality is improved, so that high precision is ensured, and manpower resources are greatly saved.

Description

technical field [0001] The invention relates to a numerically controlled double-sided grinding machine for a high-speed steel circular saw blade, which can simultaneously grind and process two end surfaces of a thin-disc workpiece. Background technique [0002] The existing high-speed steel circular saw blade is processed by ordinary lathe, which adopts the spindle and disc tooling to rotate the workpiece, the grinding wheel is fixed on the tool holder, and the manual single-sided grinding method is adopted, that is, single-sided grinding is carried out, and one side is ground and then disassembled. After that, install and process the other surface. This method can easily cause one-way extrusion deformation for thin disk workpieces, and the thickness of the workpiece is uneven, resulting in low machining accuracy of the workpiece. Due to the backwardness of the existing machine tool automation, the processing is not only The cost is time-consuming, and the pass rate is extre...
