To choose the right oneCNC vertical lathe, we must carefully read the following three points, the following small series for you to introduce in detail how to correctly choose the right CNC vertical car?
1. The selection of the processed object determines the purchase object
First of all, we must clearly prepare the object of processing. Generally speaking, parts with the following characteristics are suitable for CNC vertical lathe processing: multi-process intensive workpiece refers to the need to use many tools for processing on a workpiece. For example, a multi-hole machining with a positioning hole spacing accuracy requirement is convenient to implement by using the high positioning accuracy of the machine tool. Repeated production of workpieces suitable for processing a single piece of small batch production. Small batch refers to 1-100 pieces, each batch of numerical control vertical lathe, but need to repeat production.
In addition, even if the workpiece shape size is different, but is a similar workpiece, easy to achieve group machining (GT) process parts. Complex-shaped parts such as molds and aviation parts can be used to process various special-shaped parts on CNC vertical lathe with the help of automatic programming technology. Box, plate parts in the horizontal CNC vertical lathe use of rotary table, multi-faceted processing of box parts, such as spindle box, pump body, valve body, internal combustion engine cylinder, etc. If even the top surface needs to be machined in one clamping, a five-sided CNC vertical lathe can be selected. Vertical CNC vertical lathe is suitable for processing box cover cylinder head, plane cam, etc. Gantry CNC vertical lathe is used to process large boxes and plate parts, such as diesel locomotive cylinder block, CNC vertical lathe column, bed, printing wall board machine, etc.
2. The selection of machine tool specifications According to the size of the workpiece, the size of the table of the machine tool and the stroke of the three linear coordinate systems are determined accordingly. The size of the worktable should ensure that the workpiece can be clamped smoothly on it, and the processing size must be within the stroke of each coordinate. In addition, the limitation of tool change space and coordinate interference area should be considered.
3. The precision of the selected numerical control vertical lathe of machine tool precision is classified into ordinary type and precision type. The main precision items are shown in the following table: the main precision items of numerical control vertical lathe are ordinary type (mm) precision type (mm) linear positioning accuracy 0.01/whole process 0.005/whole process repeated positioning accuracy numerical control vertical lathe 0.006±0.002.
