Basic knowledge of computer gong processing and feeding mechanism

The basic knowledge of high speed computer gong processing feeding mechanism

1. Auxiliary device

Computer gong processing index control feed machine some necessary components, to ensure the operation of CNC feeder, such as cooling, chip removal, lubrication, lighting, monitoring and so on. It includes hydraulic and pneumatic devices, chip removal device, exchange table, CNC turntable and CNC dividing head, as well as cutting tools and monitoring and detecting devices.

1. Driving device

Gong machining is the driving part of the executive mechanism of CNC feeding machine, including spindle drive unit, feed unit, spindle motor and feed motor. Under the control of the numerical control device, he realizes the spindle and feed drive through the electric or electro-hydraulic servo system. When several feed linkage, positioning, straight line, plane curve and space curve processing can be completed.

1. Host computer

It is the main body of CNC feeder, including body, column, spindle, feed mechanism and other mechanical components. It is a mechanical part used to complete various cutting processes. Programming and other auxiliary equipment: it can be used to program and store parts outside the machine.

1. Numerical control device

High speed computer gong machining is the core of CNC feeding machine, including hardware (printed circuit board, CRT display, key box, paper tape reader, etc.) and corresponding software, which is used to input digital parts program, complete input information storage, data transformation, interpolation calculation and realize various control functions.

1. In the process of large CNC machining, the worktable may require forward or reverse operation at any time according to the shape of machining track. Dongguan mold processing center prompts you to consider the conversion of electrical energy and mechanical energy between starting and braking during forward and reverse operation, so as to realize rapid braking.
2. In order to adapt to different processing conditions, servo has a wide range of speed regulation and excellent speed control characteristics.
3. High rigidity and high speed stability servo for large CNC machining should keep the feed speed constant under different load conditions or when cutting conditions change. Dongguan machine parts machining requires servo to have excellent static and dynamic load characteristics.
4. Fast response and no overshoot. In order to ensure the contour cutting shape accuracy and low surface roughness of the machined surface, the servo should have good fast response characteristics and no overshoot.
5. High precision in order to meet the machining accuracy, it is necessary to ensure the positioning accuracy and feed accuracy of the machine tool, that is to say, the servo should have high static resolution, and the dynamic characteristics should be at least a first-order error free system.
6. Large CNC machining low speed and high torque, the characteristics of machine tool processing is cutting at low speed, the feed drive should ensure rated torque output at low speed, that is to say, servo should have constant torque output.
