The TH5632C machining center adopts the FANUC0-MD numerical control system. During the test run before an emergency mission, due to operational errors, when the tool magazine is being indexed, pressing the reset switch on the operation panel causes the tool magazine to stop automatically and control. The system alarms, the position is wrong when the magazine is stopped. At the same time, each switch of the main operation panel is locked, the manual operation mode is out of order, and the whole machine tool is in a crash state.
Fault analysis: After the fault occurs, the entire machine tool is inspected, and the control system is initially determined to be normal, and the fault belongs to the machine side fault. From the position of the Markov mechanism of the rotary positioning of the tool magazine, since the index pin is just at the dead point of the Markov mechanism, the position sensor cannot accurately determine the position of the current tool magazine, so that the control system cannot clearly detect the signal. Causes the control system to continue executing program commands, causing the system to freeze.
Solution: To solve the crash problem, make the magazine in a detectable position. When the magazine returns to the starting position and then returns the entire system to its original state, the device can be put into normal operation. According to this idea, the tool holder indexing position fixing nut is loosened, and moved backward by 1 cm, so that the sensor completes counting once, and the entire control system is out of the crash state. Through the switch on the control panel, the indexing of the tool magazine in the system is changed to manual operation, and the tool magazine is returned to the initial position by stepping the manual button on the machine side, and then the whole system is returned to the initial state, and the magazine position is restored. The sensor is reset, the tool table is reprogrammed, the system is restarted, and the device is working properly. This method not only saves time, but also has no effect on machine accuracy.

Superaudio induction heating equipment is mostly used for surface quenching of industrial metal parts. It is a kind of metal heat treatment method that makes the workpiece surface generate a certain induced current, quickly heat the surface of parts, and then quickly quench. Super audio induction heating equipment, that is, induction heating of the workpiece, in order to quench the surface of the equipment.
The principle of super audio induction heating equipment: it is the use of high frequency current flow direction is wound into a ring state or the shape of the heating induction coil, high frequency induction is usually made of red copper hollow pipe. A powerful magnetic beam that generates a transient change of polarity in a high-cycle induction coil places the metal in need of heat treatment in a high-frequency coil, and the magnetic beam penetrates the entire heated metal object. In the interior of the induction heating object and the induction heating current in the opposite direction, the corresponding strong eddy current. Because there is resistance in the induction heating metal, so strong joule thermal energy is generated, so that the temperature of the induction heating object rises rapidly, so as to achieve the purpose of heat treatment. Therefore, super audio induction heating equipment in the industry, can also be called: high frequency induction heating equipment; High and medium frequency induction quenching equipment; Induction diathermy equipment; High frequency quenching machine, high frequency induction heating machine, high frequency welding machine.
Performance and characteristics of super audio induction heating equipment:
Fast heating: the fastest heating speed is less than 1 second, (the speed can be adjusted and controlled)
Wide heating: can heat all kinds of metal workpiece (according to the different shape of the workpiece to replace the detachable induction ring)
Easy to install: connect the power supply, the induction ring and the water pipe can be used; Small size, light weight, very easy to use
Easy to operate: It can be learned in minutes
Quick start: heating can be started after the water is connected to the electricity
Less power consumption: about 70% power saving than the old vacuum tube high IF equipment, the smaller the workpiece, the smaller the power consumption
Good effect: heating is very uniform (can also adjust the density of induction ring, so that each part of the workpiece to obtain their own required temperature), fast heating, less oxide layer, no waste after annealing
Power adjustable: stepless adjustment of output power
Full protection: with over voltage, over current, over heat, water shortage and other alarm instructions, and automatic control and protection
