Accuway Super Heavy Duty Turning Centre

Slant Bed Design

  • The 45 degree slant bed structural design consists of a one piece bed and box way casting with low center of gravity, large swing diameter, superior rigidity for easy disposal of coolant and chips and longer tool life.
  • Bed structure is internally reinforced with numerous heavy ribs to reduce deformation from shear or tensile stress.
  • Fine grain wear resisting, shock-absorbing Meehanite cast iron is heat-treated, annealed twice and ground to eliminate internal stress as well as naturally seasoned to attain stability and hardness of HRC 53. This ensures the high rigidity with minimum deformation to meet tough demands from continuous heavy duty and/or step cutting.

Powerful Main Spindle Design

  • Power is delivered to the spindle through a two speed geared head allowing stable spindle speed changes as well as powerful torque output..
  • Helical gears are incorporated in the gearbox to reduce noise, increase contact area, and reduce backlash for even high precision cutting.
  • Headstock design, uses symmetrical heat-dissipating ribs, precision-bored and ground to reduce error from heat distortion, maintain circularity and concentricity, thereby ensuringlong-term cutting accuracy.
  • Every spindle is assembled, along with headstock and bearings, in a temperature controlled environment and with precise fitting jigs. Then it undergoes extensive run-in test to eliminate bearing mismatch arising from elevated temperatures.

Special Turret Design and Precision Motion Control

Heavy duty servo controlled turret with 2-piece large diameter Hirth-type coupling provides strong clamping, high stiffness, high loading capacity, and precise positioning accuracy. Bi-directional indexing of the 12-station block type turret top plate allows shortest path indexing for reduced non-cut time.

Tailstock

The high-precision tailstock quill encased in a sleeve is fully programmable. The tailstock body is mounted on box ways to ensure maximum rigidity for greater stability when machining long and heavy components between centers, allowing closer tolerances and better surface finishes.

Heavy Duty Servo Mechanical Power Turret + C-axis index control
To cope with rigorous heavy cutting demands, the power turret features a special driving method that is superior to the VDI design, offering 11 kW of driving power for rotary tools to satisfy versatile heavy cutting process.
