VERTICAL TURNING CENTER
Machine Features :
The one-piece column made by Meehanite cast iron with wide span ribbed box structure provides strong stability and rigidity. It dramatically decreases vibration, thermal expansion, and deformation caused by cutting stress. The over size box sliding ways are heat treated to Rockwell 55 degree and stress relieved. All contact surface on all casting components are hand scraped to ensure the tightest fit and highest accuracy possible. The result of the intensive details put into this assembly is ultimate damping, which provides longer tool life and improvements in part surface finishes.
Massive Hydraulic Clamps Lock Cross Rail
The height of cross rail is adjustable according to different geometric part’s dimension. The total 800 mm stroke of rail travel has evenly divided by 5 positions. Every position is locked by four strong independent hydraulic clamping cylinders plus large taper lock pins. It strengthens the rigidity of the cross rail, tooling, and also provides excellent positioning as well as repeatability. The 15 degree slant bed cross rail design dramatically decrease the overhang problem of tool RAM. The heavy duty one piece casting also increases damping character as well as machine stability.
Slant Bed Cross Rail Design
The 15-degree slant bed designs to reduce overhang problem and increase rigidity of machine.
Octagon RAM Design
Because of the unique structure design, a revolutionary octagon RAM design provides excellent straightness and thermal expansion control. From experiment, this special octagon RAM provides superior damping characteristics, excellent thermal expansion control, and stronger rigidity than traditional square RAM. The octagon design provides minimum through-hole capacity and allows better clearance to bore a deep hole. It increases about 23% more clearance than same size of square RAM.
Work Table & Gear Box
The floating hydraulic bearing design using heavy duty taper roller bearing; it is built in onepiece base casting. The enormously table load capability is more than double compare to peer model. The high torque, 2-speed gearbox incorporates with Fanuc 40/6000i spindle motor provides extremely up to 23,270 N-M cutting power to overcome all tough jobs.
