Rotor of turbine of main shaft of report of turbine rotor wind is used more wait for material for steel of stainless steel, alloy steel, carbon or cast steel. But to lower hear rate, turbine vapour pressure and temperature are higher and higher, because high temperature alloy has good high temperature strength, thermal stability and heatproof and fatigue special property, the network of look forward to of more and more extensive search that because alloy of this high temperature is in turbine and gas turbine,uses, this raised taller requirement to cutting tool. Solution: Outside turning of round end panel -- turning of CNMG190612-ER profile modeling -- RCMT2507MO grooving machines -- of small squirrel series 1) outside round turning cutting tool: PCLNR4040R19nextpage razor blade: CNMG190612-ER 2) of of RCMT2507MO of of copy travel turning 3) grooving is machined -- small squirrel series to generating electricity the special grooving treatment of the industry uses cutting tool, can design a concept to measure a body to have something made to order for the client according to small squirrel cutting tool!
