Product information
Due to its light weight, high strength, good processing performance and environmental protection characteristics, aluminum alloy is widely used in many aspects such as body structure, engine parts, wheels, suspension systems, heat exchangers, body outer panels and so on in the automotive industry. It is One of the key materials driving the development of the automotive industry. The aluminum alloy gearbox housing is an important part of the automobile transmission system. Its role is to protect and support key components such as gears, shafts, and bearings inside the gearbox.
Customer pain points
During the mass production of gearbox casings, aluminum chips may get stuck between the tool holder and the spindle, causing changes in tool length or runout, resulting in product quality risks. The customer urgently needs to reduce its quality risks and improve the stability and reliability of mass production of gearbox housings.
Solution
By applying the UJ-RCS tool holder chip abnormality monitoring system , product quality risks caused by changes in tool length or runout caused by chip jam in the tool holder are avoided. Principle of the UJ-RCS toolholder chip abnormality monitoring system: In aluminum alloy processing, aluminum chips may adhere to the tool holder. The spindle usually blows air when changing the tool, but occasionally there will still be problems with aluminum chips getting stuck between the tool holder and the spindle, causing the tool length or The runout value changes and creates a quality risk. The purpose of chip jam detection is to detect the status of the tool after starting the spindle for tool change and before cutting into the workpiece. If it is determined that the chip is jammed, an alarm will be issued immediately and the machine tool will be stopped to avoid scrapped products caused by tool processing with chip jam problems.
On-site execution effect
Chip monitoring
After chip jamming occurs, the abnormal monitoring system for chip jamming in the tool handle can control the machine tool to stop. There is an alarm pop-up window on the monitoring terminal, which can promptly remind people to clean the aluminum chips on the tool handle.
Customer value
The detection accuracy of chip monitoring is 0.02mm
Product quality risks caused by changes in tool length or runout caused by chip jamming in the tool holder are avoided.
Real-time monitoring
Monitor chip jamming abnormalities in tool holders to reduce quality inspection costs.
