Gantry CNC Machine Center
Double Column CNC Machine Features
Strong Cutting Capacity
►The Machine matched with 7:24 Taper No.50 Spindle,P4 grade angular ball bearing,the spindle speed can reach 6000rpm,Full gear Spindle and 2 swifts gearbox optional for heavy duty machining.the machine can supply sufficient power and torque output for various cutting processing after adoption of Japanese FANUC α series spindle motor or Mitsubishi/Siemens Spindle Motor.
The Excellent Feeding Structural system
►Aside from the design of collision-preventing device,C3 grade precise ballscrews on XYZ Axis have set extra pre-pull function at each end of ballscrew,which decreases thermal deformation caused by ballscrews temperature rising.
The Most Excellent Strength in Structure
►Heavy & Strong machine is absolutely an essential part for gantry machining center,made of qualified Meehanite casting iron GC-276 by tempering treatment,MAXTORS CNC Machines have high rigidity and admirable stability.
►Structure size with finite element analysis(FEA) brings excellent static rigidity and shock resistance,preventing the appearance of cutting resonance,thus enhancing processing accuracy and prolonging tools service life.
The Most Applicable Spindle Box
►The Spindle Box is designed on the base of the most suitable rectangular ratio of cross-section modulus coefficient ,supporting wonderful processing rigidity when Z Axis reach max.travel.
►The interlayers with Circular Arc ribs are adopted inside the spindle box to strengthen structural body,providing the machine with best dynamic rigidity and stability during rapid feeding and heavy cutting.
The Most Excellent Z Axis Response System
►Z Axis design With bidirectional loop counter balance by nitrogen or large size Z Axis motor, has tightly connected the driving mechanism on Z axis,totally meet the requirements of precise response system for Z Axis servo motor & high thrust processing.
►Elaborate centre-symmetric spindle system with Optimum Structure layout for spindle,spindle motor,ballscrews and counter-balance cylinder,avoiding thermal deformation caused by temperature rising and reducing the appearance of unbalanced moment.
The Most Excellent Feeding System
►RG Series Linear roller-type guideway on X Axis and Y Axis,heavy loading precise P grade linear slide guideway with 0.003-0.005 low frictional coefficient make it possible to have a low viscosity and high driving sensitivity and greatly improved dynamic precision,hard rectangular guideway on Z Axis covered with imported low frictional TURCITE-B and by accurate scratching treatment ensures feeding quality of the machine(low frictional coefficient and low friction resistance) and necessary cutting rigidity.Z Axis optional with Linear guideway to meet high speed high precision requirements.
The Advanced Control System
►Standard advanced FANUC or MITSUBISHI Controller provides the machine stable and high-efficiency numeric control.
►The machine can be optional with more powerful functional controller and more precise closed-loop controller unit as requested to meet different demand.
