How to choose the processing center

1. The selected to determine the object before the choose and buy of the object being processed


The first thing to clear preparation processing object.In general, have the following characteristics of parts suitable for machining center, more working procedure refers to the intensive workpiece on a workpiece need to use many of the cutting tool machining.Positioning tedious artifacts such as a certain pitch accuracy of porous processing, advantage of the characteristics of machine tool positioning accuracy high, easy to implement.Repeat and machining is suitable for production of sheet small batch production.Small batch refers to the 1-100 pieces, each batch quantity is not much, but need to repeat the production. 


In addition, even if the shape of workpiece size is different, but it is similar to the workpiece, easy to implement group machining parts (GT) process.Complex shape parts mould, aviation parts such as complicated shape workpiece, can use the automatic programming technology in machining center processing various special-shaped parts.Enclosure, plate parts using rotary table on the horizontal machining center, to polyhedral box body parts processing, such as the spindle box body, pump body, valve body and internal combustion engine cylinder block, etc.If the top surface also want a clamping in processing, can choose pentahedron machining center.Vertical machining center for machining lid cylinder head, planar CAM, etc.Gantry machining center for machining large enclosure, plate parts, such as diesel engine cylinder block machine, machining center, lathe bed, printing the post wall, etc. 
 
2. The machine specifications of the selected according to determine the size of the machining size, determine the corresponding machine tool table size and three linear coordinate system.Should guarantee the workpiece on the workbench dimension can smooth the clamping workpiece, processing size must be within the coordinate travel, in addition to consider change the coordinates and space interference zone limits. 
 
3. The machine tool selection of precision machining center in classification accuracy for normal and precise, see table of the project: the main precision machining center main precision accuracy of project project type (mm) precise (mm) linear positioning accuracy of + / - 0.01 / full/full repeat positioning accuracy + / - 0.006 0.005 mm + / - 0.002.
