● high rigidity thick beam structure, effectively improve the shape of the track across the stepped beam, increase the distance, and provide the best axial movement of the y-axis Straightness and heavy cutting rigidity. ● Y-axis adopts heavy-duty roller slide rail, which can increase the rigidity of ball type by more than 40%, providing higher cutting load and higher service life. ● the base is supported by three (roller) guide rails. The left and right two rails are designed with large-span symmetrical workbench load center of gravity, and the middle rail is designed with The transmission screw is designed with the minimum span and symmetrical motion center, so as to achieve the most true straightness of the whole stroke. ● full stroke track support design, thick and ultra wide design size of the base structure, with high rigid structural foundation, greatly improve the load capacity of the workbench and the dynamic horizontal accuracy of workpiece movement, and achieve the stability and seismic resistance of cutting. ● one piece cast column structure, with thick column section size, can effectively connect the rigidity transmission between the beam and the base, and greatly improve the cutting rigidity of YZ axis. ● the base, workbench, column, beam, saddle and spindle head are all made of high-quality cast iron.
