| The classification and structure of nc machine tools |
|
CNC machine can have multiple classification, one of the main categorization is:
1) according to the classification of processing methods
A metal cutting class CNC lathe, CNC machining center, such as CNC drilling machine, CNC grinding machine, CNC, boring, etc.
B metal molding CNC machine such as CNC bending machine, CNC pipe bender conveyor chain, nc obtained.in etc.
C nc machine tools such as special nc line (electrode) cutting machine, CNC machine, CNC edm machine etc laser cutting.
D other types of nc machine tools such as flame cutting machine, CNC tri-ordinate measuring machine, etc.
2) according to the numerical control system level classification
A high-grade nc machine tools
B middle-grade nc machine tools
C low-grade nc machine tools
3) according to the classification of CNC function
A economical nc machine tools, simple, less function (easy) prices.
B the function of nc machine tools (standard nc machine tools.
2. Of nc machine structure diagram:
Each part features:
1) program - programmer written parts processing program.
2) input device - a program, as the input into the CNC instructions operating equipment, mainly responsible for entry procedures and parameters. (system operation panel, paper machine, computer),
3) output devices -- will procedures, instructions, or output parameters, so that such operator control.
4) CNC computer, digital control system, the whole machine is controlled, the brain from all instructions are issued, including interpolation operation, trajectory control, the position control, alarm, the program shows, etc.
5) can process -- PLC controller or PC, is the machine and CNC interface between, because that can receive and control CNC signals are weak signal, and the auxiliary tool for high voltage signal of cooling and lubrication conveyor chain, if necessary, among them with signal isolating devices, otherwise not only increase conversion system power, more important is to interfere with the normal work of the system.
6) for CNC servo - a shaft of spindle work instructions (direction and speed, etc.) for power amplifier, driver spindle motor rotate.
7) spindle motor.
8 for CNC servo amplifiers) - a axis displacement controlled instruction for power amplifier, driver each axis rotation servo motor.
9) servo motor drive each axis, ball screw rotation, moving workbench.
10) position detection, direct or indirect measurement of workbench measure position, CNC, the CNC feedback to compare, internal control commands and output displacement worktable for further movement.
