SC introduced the M6132 face mill, a product designed for coarse, stainless steel turbine housing. The positive geometry of the tool provides smoother cutting, which helps the machine shop to eliminate vibrations. In turn, higher metal removal rates are reported to be achievable, shortening the cycle. The geometry and the quality of the edges also help to ensure the reliability and the number of components added to each insert.
“In the traditional cast iron, stainless steel is a kind of more popular material choice, because of its material properties can help improve the exhaust temperature to 1300 degrees Celsius, and corrosion,” Jacques Gasthuys said, he is sandvik comair’s car application engineer. “Annual production of about 50 million turbocharger iron and stainless steel, but the cost of processing stainless steel up to 20 times, because of the characteristics of these operations is very short and irregular insert tool life, and uneven wear.” Our goal is to develop a powerful cutting tool that can help reduce component costs.
In the crude turbine exhaust, the main challenge is the complex shape of these thin wall parts and its complex clamping force, making it an easy to vibrate operation. The new M612 face milling cutter is designed specifically to solve this problem. Its positive geometry provides smooth cutting motion, reduces energy consumption, and eliminates the vibration of rough operation. This allows greater metal removal and faster cycle time, combined with 12 cutting edges, with six on each side to help reduce the cost of each component. The round insertion option also increases the flexibility of the machine shop, while the inserted indexation interface provides both accuracy and repeatability.
Use level in user stories GC43240 insert rough stainless steel exhaust turbine housing, using M6132 face mill instead of rival knife allows shaft speed increased from 212 to 273 rev/min, the cutting speed increased from 70 to 90 m/min (230 to 295 feet per minute) and feed increased from 0.13 to 0.18 mm (0.005 to 0.007 inch). In the same 2.5mm (0.098-inch) deep cut, the test results showed that M6132 face3mill reduced the processing time of each component by 27%, while tool life increased by 172%.
