The general treatment method is to use manual handheld polishing equipment to remove the burrs. This operation method is not only inefficient, but also easy to cause work injuries. There is also a method of treating the auto parts with low temperature and then using high-speed sprayed frozen particles to impact the product to remove burrs. This method requires continuous removal and insertion of frozen particles, but when taking out the finished product, the low temperature may not have completely dissipated, which may cause frostbite to the workers. For this reason, we propose a device for abrasive flow polishing of automotive titanium alloy exhaust pipes.
