First of all, it is necessary to clearly prepare the goal of processing. In general, parts with the following characteristics are suitable for machining in vertical machining centers: Multi-process intensive workpieces refer to the processing of many tools on one workpiece. For example, a workpiece with complicated positioning has a multi-hole process that requires the accuracy of the positioning hole pitch. It is very convenient to use the feature of high positioning accuracy of the machine tool. Workpieces of repetitive production type are suitable for processing a single piece of small batch production. Small batch refers to 1-100 pieces, each batch is not large, but it needs to be produced repeatedly.
In addition, even if the workpiece shape and scale are different, but they are similar workpieces, it is easy to complete the group processing (GT) process of parts. Complex shape parts, molds, aerospace parts and other complex shape workpieces can process various shaped parts on a vertical machining center with automatic programming skills. The box and plate parts are processed on the vertical machining center using a rotary table to process the box parts on multiple sides, such as the spindle box, pump body, valve body, internal combustion engine cylinder, etc. If even the top surface needs to be processed in one clamping, a pentahedral machining center can be used. The vertical machining center is suitable for processing box cover cylinder head, plane cam, etc. The vertical machining center is used to process large box and board parts, such as diesel locomotive cylinder, machining center column, bed, printed wallboard machine, etc.
The selection of the machine tool specifications is based on the determined size of the workpiece to be processed, and the required table size of the machine tool and the travel of the three linear coordinate systems are determined accordingly. The workbench scale should ensure that the workpiece can be clamped smoothly on the workpiece. The machining scale must be within each coordinate stroke. In addition, the limitations of the tool change space and each coordinate interference zone must be considered.
