The invention provides a numerical control vertical hot ring rolling mill and a control method. The numerical control vertical hot ring rolling mill comprises a rack, a roller mechanism, a measuring roll mechanism, a guide roll mechanism, a core roll mechanism, a feed mechanism and a control device. A ball screw is driven by a servo motor to drive a rolling wheel to move. The measuring roll mechanism is a follow-up measuring roll mechanism provided with a displacement sensor. The position can be adjusted through a lead screw to adapt to measuring of ring pieces of different dimensions and specifications in the rolling process. Parameters are input into a PLC, and numerical control of the vertical hot ring rolling process is achieved. By means of the numerical control vertical hot ring rolling mill and the control method, manpower can be saved, materials can be saved, the part forming accuracy can be improved, and the subsequent machine machining amount and the rejection rate can be reduced.

The invention provides a high-frequency induction heating chemical dressing device for a brazed diamond abrasive router. According to the high-frequency induction heating chemical dressing device, real-time high-temperature graphitization chemical dressing of the brazed diamond abrasive router on a machine can be realized, the air in a dressing area can be effectively isolated under pure nitrogenprotection or the isolation atmosphere, the oxidation loss of an ultrahigh-strength steel high-temperature dressing base body in a high-temperature environment is greatly reduced, and the use period and the use stability of the ultrahigh-strength steel high-temperature dressing base body are improved; a nitrogen protection connector or an isolation atmosphere connector and a high-frequency induction heating coil are all connected with a control valve of a numerical control machine tool, and therefore all PLC data can be read by a PLC while the pressure, the flow as well as the start and stop can be controlled, the numerical control machining program and the start-stop control of the dressing device can be built in, and the numerical control is completely realized; and a built-in type thermocouple is used for measuring heat deformation before the use of the ultrahigh-strength steel high-temperature dressing base body and the use process of the ultrahigh-strength steel high-temperature dressing base body and for controlling the environment temperature in the dressing process.

The invention discloses a five-axis linkage numerical control polishing machine which comprises a machine base and a main shaft and is characterized in that one surface of the main shaft is provided with a polishing head; the other side of the main shaft is provided with a Z-axis feeding platform; an X-axis feeding platform is arranged near the main shaft; the X-axis feeding platform and the Z-axis feeding platform are vertical to each other; the machine base comprises a Y-axis feeding platform, a vertically rotary motor and a working table surface; the Y-axis feeding platform is arranged in the middle of the machine base; the vertically rotary motor is arranged at one side of the machine base; the other side of the machine base is provided with the working table surface; the Y-axis feeding platform is provided with a movable table surface; a horizontally rotary motor is arranged at the lower part of the movable table surface; therefore, the machine has the advantages of high locationprecision and constant polishing effect; the motor drive can achieve the high rotation speed (10000 rpm to 20000 rpm); the machine can be freely switched between the dry polishing and the wet polishing; and the machine can be used for improving the flexibility of working hours, making up for the deficiency of the prior art, improving the production efficiency and realizing complete numerical control and intelligence.
