Graphite Electrode Machine : Features 1.The major structures are manufactured from Meehanite cast iron, stress relieved and combined with scientific rib reinforcement to ensure deformation-free operations. 2.Increase width on the column bottom with box-type structure provides maximum stability especially when performing high speed cutting. 3.Linear ways on three axes assure high feed rates and extremely smooth motion. 4.Extra wide span between linear ways greatly increases machine stability. 5.The structural parts are analyzed and designed by the advanced Finite Element Analysis. It provides a detailed analysis for structural stress/strain conditions, and ensures excellent machine rigidity and lifetime stability. 6.Linear guide ways: The machine employs 45mm wide ball-type linear guide ways. (Optional) 7.Precision ball screw: Three axes are transmitted by high precision C3 grade ball screws, preloaded, hardened and ground-assuring dependable feed accuracy. 8.Choice of 30,000 rpm high speed spindles are designed for high speed machining requirement. 9.Extra wide column bottom and base ensure simplified machine structure for space saving. 10.The three axes ball screws are directly coupled to servos through backlash-free couplings. This ensures dependable positioning accuracy. High precision class C3 ball screws are preloaded to eliminate thermal strain.
