Abstract
The paper shows the results of the research of opportunities to increase the durability of the end coated mills when machining titanium alloys due to bedding. To this purpose the existing methods of improving the durability of tool materials are analyzed. It is noted that for the cemented carbide hardening before coating, the methods of surface hardening are widely used. In order to further improvement of tool durability by the example of milling alloy BT6 using carbide cutters, vibroabrasively machined before TiAlN coating. The possibility of further durability increase of the instrument due to bedding in «Promoledge 9 %» technological environment is examined. It was supplied to the cutting zone with minimum lubrication method. Bedding was carried out under the following conditions: Sz = 0,03 and Sz = 0,05 mm/tooth, t = 1 mm; V = 10 m/min., V = 15 m/min., V = 20 m/min., V = 25 m/min. The research shows that the recommended speed to further increase of the durability of end mills is V = 20 m/min. In this case, there is a durability increase when applying Sz = 0,03 mm / tooth to 1,5 times and at Sz = 0,05 mm / tooth – 2 times.
