CNC vertical machining center refers to the spindle axis and the table vertical set of machining center, mainly suitable for processing plate, plate, mold and small shell complex parts. Vertical machining center can complete milling, boring, drilling, tapping and cutting thread and other processes. Vertical machining center is at least three axis two linkage, generally can achieve three axis three linkage. Some can carry out five axis, six axis control.
Vertical machining center column height is limited, the box type of workpiece processing range to reduce, this is the disadvantage of vertical machining center. But vertical machining center workpiece clamping, positioning convenient; Easy to observe the motion track of the cutting tool, convenient to check and measure the debugging program, and timely find problems, stop processing or modification; The cooling condition is easy to establish, and the cutting fluid can reach the cutting tool and machining surface directly. The three coordinate axes are consistent with the Cartesian coordinate system, which is intuitive and consistent with the visual Angle of the pattern. Chips are easy to remove and fall, and avoid scratching the processed surface. Compared with the corresponding horizontal machining center, the structure is simple, the footprint is small, the price is lower.
CNC VMC classification standard:
Classification by guide rail
According to the form of vertical machining center axis guide rail can be divided into hard rail and line rail. Hard rail is suitable for heavy cutting, and line rail movement is more sensitive.
Classification by speed
Vertical machining center spindle speed 6000-15000rpm for low speed type, 18000rpm for high speed type.
Classification by structure
According to the structure of vertical machining center bed can be divided into C type and gantry type.
