Product Description

1) CNC gantry machining center;

2) Strong massive machine is absolutely an essential part for gantry machining center. Made of qualified Meehanite cast iron GC-276 and delt with tempering treatment, DATAN machines have high regidity and admirable stability.

3). Structure size with finite element analysis(FEA) bringss static rigidity and shock resistance of machine to a full play, preventing the appearance of cutting resonance, thus enhancing processing accuracy and prolonging tool service life.

4). The spindle box is designed on the base of the most suitable section- coefficient rectangular ratio with ratio 1: 1.15, supporting wonderful rigid processing with longer travel along Z axis;

5). The interlayers with arcuate ribs are adopted within spindle box to solidate structural body, providing the machine with best dynamic rigidity and stability during rapid feeding and heavy cutting.

6). With design of bidirectional balance loop and double N2 cylinders for counter balance, the machine has tightly connected the driving mechanism to Z axis, totally providing precise response system for servo motor on Z axis and need for high thrust processing.

7). With elobrate centro-symmetric main spindle system, the machine have made a reasonable and overall position arrangement for spindle, spindle motor, ballscrews and bidirectional N2 cylinders, avoiding thermal deformation caused by temperature rise and reducing the appearance of unbalanced moment.

8). Standard advanced FANUC or MITSUBISHI controller provides with the machine a stable and efficient numeric control;

9). The machine can be optionally equipped with a powerful functional controller and a more precise closed-cycle control unit based on clients' various needs;

10). RG series linear roller-type guideway on X axis and Y axis and heavy-load and 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 improve dynamic precision; Hard rectangular guideway on Z axis covered with imported low frictional TURCITE-B and delt with accurate scratching treatment ensures motional quality of the machine( low frictional coefficient and low friction resistance) and necessary cutting rigidity;

11). Aside from the design of collision-preventing device, C3 grade precise ballscrews on X, Y, Z axis have set extra pre-pull function at each end of ballscrew, which decrease thermal deformation casued by ballscrew temperature rise

12). The spindle with 7: 24 taper( No 50, main spindel bearing diameter: 100mm) worked with P4 grade angular ball bearing, the spindle speed can reach 6000rpm. Matching with German ZF-DOUPLAN precise low-high gear transmission box, the machine can supply sufficient power and torque output for various cutting processings after adoption of Janpanese FANUCα Series spindle motor or Japansese MITSUBISHI spindle motor.
