What tool is suitable for titanium alloy processing?

If titanium alloy special milling cutters are not used for processing titanium alloys, the CNC cutters will inevitably be easy to collapse and wear, and the processing efficiency is low. Starting from the types of titanium alloys, the characteristics of titanium alloy processing, the selection of milling cutters for processing titanium alloys, and the cutting parameters of processing titanium alloy tools, the titanium alloy processing will be introduced in detail.



　　 One, the choice of milling cutters and cutting tools for machining titanium alloys

　　 Generally choose cemented carbide bar tools for processing titanium alloys, such as tungsten-cobalt cemented carbide, typical grades are YG8, YG6X; when choosing cemented carbide-type titanium alloy tools, you should not choose tungsten-titanium or tungsten carbide tools. TiC and TiN coated tools.

　　Secondly, cobalt-containing high-speed steel, aluminum or vanadium high-speed steel can also be selected for processing titanium alloy tools. However, high-speed steel tools have low production efficiency in processing titanium alloys and are easy to wear.

　　 General large-scale CNC tool brands, such as Swiss Fraisa, and imported DaElement brands have a series of titanium alloy milling cutters. For example, Swiss Fraisa's TX series specializes in processing titanium alloys, and Big Eleven's 7P series specializes in processing titanium alloy. Other large brands have dedicated series of titanium alloy tools.

　　 2. Cutting parameters and knowledge of machining titanium alloy milling cutters

　　 When processing titanium alloys, generally a smaller rake angle should be selected, which can significantly improve the cutting edge strength and chipping resistance; a larger clearance angle can reduce the contact area between the back of the tool and the transition surface and the machined surface; When processing titanium alloy, the cutting speed of the tool can be moderately reduced, the amount of back-cutting can be enlarged, and the feed rate should be appropriate

　　 Machining titanium alloy end mills (hard alloy) cutting parameters;

　　 milling oxide scale; milling speed 18~24m/min, feed per tooth 0.10~0.15mm/z_

　　 rough milling; milling speed 36~48m/min, feed per tooth 0.10~0.15mm/z, side tooling amount 1~4/mm;

　　 fine milling; milling speed 38~70m/min, feed per tooth 0.04~0.08mm/z, side tooling amount 0.5/mm;

　　 Secondly, when processing titanium alloy, you can choose water-based cutting fluid or no cutting fluid. Do not use fluorine-containing cutting fluids, and are not suitable for contact with aluminum, zinc-based alloys, copper, tin and their alloys.

　　 I believe you have read the above text and have a systematic understanding of titanium alloy processing and how to choose titanium alloy milling cutters. You can choose the titanium alloy special milling cutter of Fuyang Zhongrui Electronic Component Factory, or consult related CNC cutters of other brands.
