Economical nc lathe programs run processing and fault detection

With the development of the machine tool industry, the economical nc lathe more and more applied to all walks of life.The following brief introduction for the reader the economical nc lathe, processing, and the program is run fault detection.The economical nc lathe of economical nc lathe is to use digital information to realize the automatic control.At the end of the program is running, the economical nc lathe tool offside when to return to the origin, this phenomenon is commonly caused by mechanical transmission system running resistance is too large.Cutting feed, the tool rest running at low speed, low voltage driver and step motor operating torque is small, not enough to overcome the resistance caused by step.And back to zero step motor high pressure drive, high speed, torque, and no demanding resistance, stepper motor operating normally don’t throw step.Such a step to throw and return to normal will cause the above phenomena.Then can check the stepper motor slowdown in the transmission gear or between step motor and ball screw drive gear on the presence of iron foreign body, or slip sheet strip is too tight to make running resistance increases, etc.It is the process by controlling the input to the numerical control device of medium, the numerical control device after analysis and processing, signal various corresponding to the processing procedures and instructions, control machine for automatic processing.About the economical nc lathe with economical nc lathe developed on the basis of ordinary lathe, it has been greatly improve the degree of automation.Its automatic control system is mainly composed of single chip, through the control program and control machine tool of the longitudinal and transverse feed device and tool change device, automatically complete the processing of parts.It programs run over, tool return less than zero, this phenomenon is caused control system fault.Tool in the feed or running at low speed when processing requirements, the step motor speed is low, the low voltage power supply, and the program back to zero, for quick return, at this time for stepper motor speed, driven by high voltage power supply, make the output torque, to ensure normal back to zero.High voltage driver output power to control a switch triode, when switch triode damage, high speed back to zero point, high voltage power supply can’t open, stepper motor output torque is not enough, cause back to zero step, the tool can’t return the origin, the failure to replace switch triode can be removed.If you encounter such problem can be ruled out at their own discretion and processing.Economical nc lathe line fault detection of the economical nc lathe tool rest is not easy to malfunction;Electric tool post common faults: rest can’t find want to in the process of change knife knife, knife can’t lock, positioning accuracy have errors.Simple CNC lathe is a complex machine & ndash;Electrical integration equipment, and in the event of a failure to also want to from the machine mechanical structure and electric control two aspects of comprehensive analysis.Stepper motor at low speed running, step motor lose step when high speed, this phenomenon may be the driving power supply voltage is reduced, reduce stepper motor output torque.So should check the drive power supply part mainly.When high pressure after the first triode damage, high voltage power supply can’t get through, reduce high-speed stepper motor output torque, cause losing step.Can also be caused by mechanical failure.So in the case of inspect the parts failed, but should also check the screw, wire mother, slip board, stepper motor reducer parts, such as when there is a foreign body parts bending, distort, or get stuck when make running resistance increases, when running at low speed, the phenomenon is not obvious, but the speed is not completely overcome the resistance caused by the step.

Numerical control lathe claim to the sensor

Sensor CNC lathe is one of the important composition, no sensor CNC lathe will be not only a manual lathe numerical control.Sensor is a kind of can feel the provisions is measured, and convert the available output signal according to certain rules of device or devices, the input signal (measured) tend to be power, output signal are often easy to processing power, such as voltage, etc.Sensor is a lot of more phyletic, classification standard, the term is different also, common resistive sensors, inductive sensors, capacitive sensors, temperature sensors, piezoelectric sensors, hall sensor, thermocouple sensor, photoelectric sensor, digital position sensor, etc.In nc machine tools are mainly on the application of sensor, close to switches, photoelectric encoder, linear grating temperature sensors, hall sensor, current sensor, voltage sensor, pressure sensor, liquid level sensor, rotating transformer, inductosyn, speed sensor and so on, mainly used to detect the location, linear displacement and angular displacement, velocity, pressure, temperature, etc.Nc machine tool demand for sensor: (1) the high reliability and strong anti-interference;(2) meet the requirements of precision and speed;(3) use convenient maintenance, suitable for machine tool operation environment;(4) the cost is low.Different kinds of CNC machine tools, the requirements of sensor is endless also and same, in general, large-scale machine tools require high response speed, medium and high precision nc machine tools is given priority to with required accuracy.
