It turns out that when the machine fails, there is a higher value of clutter on the power supply; at the same time, the write end of the memory has a downward pulse. After detecting the waveform of the power supply, there are also clutter. This confirms the author's inference. At this point, it can be confirmed that the main cause of the machine tool failure is that electromagnetic interference from the outside causes the machine part parameters to be lost, so that the machine tool cannot work normally. It was later confirmed that electromagnetic interference was caused by a high-power electric welder in another workshop. After the power supply plus a smoothing reactor, the machine tool has been used so far, and no such problems have occurred. Example 2: In March 1999, our factory purchased two THK46100 horizontal machining centers from Kunming Machine Tool Co., Ltd., which uses a full-closed FANUCSERIESO-MC numerical control system.
After the installation is completed, after checking all the errors, the power supply starts the CNC system, and the following alarm information appears on the CRT screen: Therefore, the key inspection checks the No. 339 alarm. Check the feedback line and power line, and there is no short circuit or open circuit. Replacement of the axle card is invalid. Replace the Z-axis motor and encoder, driver, interface board, etc., the boot test failure remains. The Z-axis motor encoder feedback line M185 is interchanged with the X-axis M195. At this time, the alarm disappears, but the Z-axis motor sounds abnormally and produces a howling sound (the Z-axis motor power is greater than the x-axis power). This shows that there is no problem with the system, motor and wiring. After inspection, there is no problem with the setting of each parameter. Based on past experience, the author believes that electromagnetic interference may cause machine faults. Thus, each grounding system is re-determined. When the Z-axis motor cable is pulled out of the junction box, the malfunction disappears immediately. (Finish)
Delving Into Automotive Cast Films and Production Technology
The vehicles we drive are marvels of not just engineering, but also material science. At the core of these material innovations are "Automobile Cast Film Lines," which are critical systems used for producing the specialized films found in various car components, enhancing both aesthetics and functionality.
Where Cast Films Make a Difference in Your Car:
In the realm of automotive design and safety, cast films have several applications
Interior Films: Look inside your vehicle at the dashboard, door panels, or other trim elements and you'll likely find films made from durable materials like polypropylene (PP) or ABS (Acrylonitrile Butadiene Styrene). These provide a surface that's resilient to daily wear and tear and customizable in appearance to fit vehicle aesthetics.
Functional Films: Move to the engine compartment and you'll see cast films in parts such as air ducts and radiator grilles. These are often designed to be heat resistant or flame retardant, contributing to the overall safety of the vehicle.
Protective Films: As an optional upgrade, paint protection film is applied to a vehicle's exterior to safeguard the paint-shielding it from minor scratches, harmful UV rays, and other environmental factors.
Crafting Cast Films for the Automotive Industry:
"Automobile Cast Film Lines," also known under names like "Car Cast Film Line" and "Auto-Casting Film Machine," operate through a process known as cast film extrusion. In this process, plastic material is melted, shaped into a continuous wide and thin layer, cooled, and then neatly rolled. These lines may sometimes involve additional equipment, such as a "Multi Functional Stretching Film Machine," which allows for the film's properties to be finely tuned for specific requirements.
Choosing the Best Cast Film Line for Production
When considering an "Automobile Cast Film Line" for manufacturing needs, keep in mind:
Type of Film: Different car parts require films with varying material compositions and thus different production setups. For instance, lines for making PP interior films are distinct from those making films for the heat-exposed engine area.
Film Characteristics: Important properties like film thickness, strength, and the desired finish must align with the car part it's destined for.
Production Capacity: The capacity of the "Automobile Cast Film Line" should match your projected production volume to ensure efficiency and supply demands are met.
Advancements in Cast Film Production and Future Outlook:
The industry producing automotive films is constantly advancing. "Automobile Cast Film Lines" are evolving with a focus on lighter, more sustainable materials and adding innovative features. Gaining insight into how these machines, such as the "Auto-Casting Film Machine," create different types of films deepens our understanding of the complex details behind the car components we often take for granted.
