Generally, we use the full-automatic drilling opportunity which failures, before we introduce to you first to study the important components of the main machine: 1, drill body 2, CNC system 3, servo drive three parts, which also determines the main cause of failure In these three parts. The common fault types of automatic drilling machines mainly include:
1. Drilling machine NC system software failure. Software faults are mainly divided into application software faults and system software faults. Their main features are:
Application software failures: Mainly due to human input errors, with some contingency and randomness.
System software failures: Due to design reasons, the inherent nature of the failure.
Software failure is one of the common and easy to repair and low repair costs, so the first check is whether the software is faulty.
2, NC servo motor failure. Mainly divided into control part failure and drive motor failure, its main features are:
Control part failure: Mainly due to overload or poor heat dissipation.
Drive motor failure: Due to the poor working environment of the equipment, the drive motor is easily contaminated, corroded, worn or burned.
3, the hardware failure of the CNC system. Can be divided into permanent failure, interim failure, marginal failure three.
4, mechanical wear failure. In the course of using the automatic drilling machine, friction occurs due to relative movement, scraping and grinding of the moving surfaces, and erosion of chemical substances cause wear of parts.
5, CNC system interference failure. It is mainly divided into internal interference and external interference. Its main features are:
External interference: usually shows different characteristics with the work site and work environment, and has strong sporadic and random nature.
Internal interference: Due to system process, structure, circuit design, improper handling of power and ground lines, or changes in component performance, it appears to be very sporadic and random.
