Efficient double-end-face grinding machine and control method thereof

Abstract

The invention relates to an efficient double-end-face grinding machine and a control method thereof. The efficient double-end-face grinding machine comprises a machine body, tool feeding devices, a contact type measuring device and a feeder. Each tool feeding device comprises a spindle, a grinding wheel, a spindle motor and a tool feeding motor, wherein the spindle motor drives the spindle to drive the grinding wheel to rotate, and the tool feeding motor drives the spindle to move left and right. The contact type measuring device comprises a measuring head vertical-moving cylinder and a contact type measuring head, and the measuring head vertical-moving cylinder drives the contact type measuring head to move vertically. The feeder comprises a magnetic reciprocating workbench and a feeding motor. A five-axis control system is adopted by the efficient double-end-face grinding machine, automatic grinding, automatic compensation and automatic measuring of double end faces are achieved, coarse and fine machining and automatic measuring on the periphery of a mold core can be efficiently completed during one-time clamping of the ceramic mold core, production efficiency for the mold core is improved, and the precision and smoothness of the mold core are improved.

Description

technical field [0001] The invention relates to the technical field of grinding machines, in particular to a high-efficiency double-end surface grinding machine and a control method thereof. Background technique [0002] Grinding machines are used in high-precision fields such as two-surface grinding of bearings, connecting rods, air conditioners, etc., and are widely used in industry. The general process of traditional processing around the core is as follows: Step 1: Use manual or CNC milling machine to mill each core surface of the workpiece separately, and the workpiece needs to be re-clamped once for each side of the milling; Step 2: After the workpiece is milled, in the Grind each mold core surface of the workpiece separately on the surface grinder, and the workpiece needs to be re-clamped once for each grinding surface; Step 3: Manually measure the size of the mold core after milling and grinding with a traditional large micrometer whether it is passed. The above pr...

Problems solved by technology

The above process makes the processed mold core not meet the requirements of precision and smoothness required by the market; in the process of milling machine processing, the hardness of the cutting blade is high, and it is easy to reverse the phenomenon of the knife; through multiple re-clamping, first milling and then grinding , the process is long, the auxiliary time for clamping is long, the labor cost is wasted and the environment for processing the mold core is bad; the manual measurement is performed with a large micrometer, which is not convenient for measurement, and the human error is also large, and the measurement accuracy is low, resulting in the final product. The dimensional consistency is poor, the precision is not high, the quality of the workpiece is unstable, and the technology is backward, which is not conducive to improving the management level
