Classification and difference of vertical machining center!

Classification of vertical machining centers. 

Classify according to guideway. 

Hard rails and wire rails can be divided into hard rails and wire rails according to the form of each axis guideway of vertical machining center. 

The hard rail is suitable for heavy cutting, and the movement of the line rail is more sensitive. 

Classification according to rotational speed. 

The spindle speed of vertical machining center is 6000-15000rpm is low speed type, and 18000rpm above is high speed type. 

Classify according to structure. 

According to the bed structure of the vertical machining center, it can be divided into C type and gantry type.

The difference of Vertical Machining Center. 

Vertical type. 

Vertical machining center refers to the machining center whose spindle is vertical, its structure is mostly fixed column, worktable is rectangular, indexing rotation function, suitable for machining disk, sleeve, plate parts, it generally has three linear motion axes, and can install a turntable rotating along the horizontal axis on the worktable to process spiral parts. 

The vertical machining center is easy to install card, easy to operate, easy to observe processing, easy to debug program, and widely used. 

However, due to the limitations of the column height and tool changing device, parts that are too high can not be machined. When machining the cavity or concave surface, the chip is not easy to discharge. In serious cases, it will damage the tool, damage the machined surface, and affect the smooth progress of the machining. 

Horizontal type. 

Horizontal machining center refers to the machining center whose spindle is horizontal, usually with a rotary worktable with automatic indexing, it generally has 3-5 motion coordinates, the common is three linear motion coordinates plus a rotary motion coordinate, the workpiece after once loading, complete the processing of the other four surfaces except the installation surface and the top surface, it is most suitable to add box parts. 

Compared with the vertical machining center, the horizontal machining center is easy to remove chips, which is beneficial to the processing, but the structure is complex. the price is higher.
