Linear rail of X/Y/Z axis, composite and intergrated machining center
Advantages of the product
This type of machine can be considered as the “Aircraft carrier” of the vertical machining center; the machine tool body weighs 14 tons which is not at the same level as those of common 1265 and 1370 type machine tools; four 45mm heavy-duty roller type guide rails are applied to Axis Y, thereby making the table very stable during large-area machining displacement, without easy deformation.
55mm super-wide guide rails with 6 huge sliding blocks are applied to the Axis X and Axis Z; in this way, the machining rigidity is greatly improved; therefore, the machine tool is able to cut anything.
Structure introduction of the machine tool body
Four guide rails are applied to this machine; specifically four 45mm guide rails are used on the Axis Y, and 55mm super-wide rails are used on the Axis X and Axis Z, and 6 sliding blocks are also taken; in this way, the machine is very stable during large-area machining, and the table has super-strong bearing capacity, without easy deformation. The table is equipped with 7 slots, to facilitate machining and clamping. BT40 type spindle and BT50 type spindle are available for the customers.
