The chip conveyors are all automatic chip removal, and the start and stop of the chip conveyor can be controlled by the M command.
11. Electrical system
11.1 CNC system and servo system
The standard configuration of the CNC system of the machine tool adopts the FANUC0iTF CNC system produced by FANUC Company, and Siemens or China GSK/KND system can be selected. high advantage.
The four-servo axis system is a high-precision digital servo system with high-speed microprocessor and software servo control functions, which can realize high-speed and high-precision servo control.
11.2 Machine tool electrical system
The power circuit of the circuit has over-current and short-circuit protection, and the relevant actions of the machine tool have corresponding interlocks to ensure equipment and personal safety. The electrical system has a self-diagnosis function, and operators and maintenance personnel can observe the running status of each part of the machine tool at any time according to the indicator lights and displays.
The main electrical components of the machine tool are imported and Sino-foreign cooperation products to ensure the safety and reliability of the machine tool.
CNC machine tools have strict power requirements. When the grid voltage fluctuation exceeds AC380V±10% and the frequency exceeds 50Hz±1Hz, the power supply voltage regulator must be added, otherwise the normal operation of the CNC machine tool will be affected.
11.3 Electrical Cabinets
The standard configuration of the electrical cabinet adopts a fully enclosed structure and is equipped with an electric box air conditioner/heat exchanger to achieve the purpose of dustproof and cooling. The protection level of the electrical cabinet is IP54, and a certain space is reserved in the electrical cabinet to facilitate the expansion of functions.
The machine tool can be equipped with other functional components such as grating rulers according to user requirements.
12. Security protection
This machine tool has full shield protection, and considers a number of safety protection measures, such as: electric control cabinet safety lock, protective door safety lock, and the strengthened glass design of the protective door to ensure the safety of machinery and people.
When the machine tool encounters an external power failure or its own failure, due to the special design of the control circuit, the machine tool axis cannot move, and the cooling motor, etc., if it is already in the “starting” state, will enter the “stop” state; if it is already in the “stop” state If it is in the state, it cannot enter the startup state by itself, which ensures the safety of the machine tool. In addition, since the control program in the machine tool computer is “solidified” in the chip, and the part processing program is protected by battery power supply, the program menu stored in the computer will not be lost in the event of an unexpected power failure or failure.
The machine tool has an alarm device and an emergency stop button, which can prevent various sudden failures from causing damage to the machine tool. Due to the reasonable design of the software, the alarm can be displayed with text and alarm number on the display, and indicated by the indicator light on the operation panel; the machine tool divides the processing methods of the alarm into three categories according to the situation: “emergency stop” for emergency alarms; “Feed hold”; only “prompt” for operation errors.
