Heavy Duty CNC gantry machining center machine

Gantry machining center refers to the spindle axis and the table perpendicular to the processing center set, mainly for processing large parts. There are fixed beam (beam fixed, table movement / rotation), moving beam type (beam up and down, (The table is fixed, the gantry movement), the crane type (table fixed, beam moving) is also the above composite form of multi-class gantry machining center. Processing characteristics, ability, for the product processing purposes are not Exactly the same, structural features editor
1 workbench
The workbench of the gantry machining center is basically rectangular. Workstations, beds, columns, beams and rams and other large castings using cast iron or welding parts, casting cavity system of honeycomb composite structure, advanced design, both aging and secondary tempering treatment to eliminate the residual stress to stabilize the material , To ensure the stability of the workpiece processing accuracy and machine life.
2 gantry
The gantry consists of a beam and two columns. Divided into beams fixed, the beam by the positioning block lock section lift and the beam any type of lifting three.
3 ramps
The ram can be divided into two types: open and closed. The open-top ram is clamped to the spindle box by means of a platen, and the cross-section of the ram is large; the ramps of the closed structure are clamped in the main shaft box and the cross-section of the ram is small.
4 magazine
The basic types of the magazine are turret type, drum type and chain type.
5 attached library
Large complex parts usually require a lot of accessory head. Attachment head according to the workpiece processing requirements for special design, generally divided into right-angle head, plus head, special angle head and universal first class.
6 CNC system
CNC system suppliers are now a lot, according to the different needs of the system brand and model have different options.
7 Accuracy
The precision of the machine is the original accuracy of the machine under conditions that are not subject to external loads. Accuracy is usually used with its negative - and the ideal state of the deviation (referred to as error) to represent the smaller the error, the higher the accuracy
