roll forming machine selection and installation
(A) is processed in accordance with the size of selected parts
Specifications of the movements of smaller desktop CNC milling machine, the table width of 400mm and more in the following, it is the most appropriate machining small and medium-sized and complex-shaped surface profile milling tasks.
Specifications, such as large gantry milling machine, 500-600mm in the table above, to address the complexity of large-size machining needs.
(B) According to the precision machining parts selection
China has established the accuracy of the standard CNC milling machine, which lifts CNC vertical milling machine milling machine has professional standards. Standard coordinates of the linear motion of the positioning accuracy for 0.04/300mm, repeat positioning accuracy of 0.025mm, milling round precision 0.035mm. In fact, there were considerable precision machine tool factory in reserve than the national standard of Tolerance value about 20% compression. Therefore, the accuracy of selection, the general CNC milling machine to meet the needs of the majority of parts machining. The relatively high precision components, consideration should be given the choice of precision CNC milling machine.
(C) processed in accordance with the characteristics of the processing components to choose
The processing site is flat or box-shaped contour level at all levels, then the choice of point system --- a straight line if the processing of CNC milling machine can be part of the surface profile, should be based on the geometry surface decided to choose the two-axis and Coordinate linkage system. Parts can also be processed in accordance with the requirements of the CNC milling machine in the general on the basis of the increase in CNC dividing head or rotary table CNC, machine tool system at this time for four of the numerical control system coordinates, you can spiral groove processing blade parts and so on.
(D) Based on parts of the bulk or other requirements to choose
For high volume users may be a dedicated milling machine. If it is small quantities and is often cyclical repeat operation, then the use of CNC milling machine is very suitable, because the first batch of workers to prepare a lot of fixtures, stored procedures can be reused. From a long-term considerations, a high degree of automation in place of an ordinary milling machine milling machines, reducing the amount of labor of workers to increase productivity trend is inevitable.
Second, the installation of CNC milling machine
CNC milling machine is a general mechatronics design, delivery from the factory to the user, are whole shipment, without the disintegration of packaging. After the machine tool so that users receive, just to the provisions of Statement. Attention to the following areas:
Box
Machine out of the box, the first signs in accordance with the packaging to find random technical documentation, technical documentation in accordance with the packing list in Annex inventory, tools, spare parts and so on. If the box with the packing list does not match in kind, should be associated with the factory. Then, carefully read the prospectus, in accordance with the guidance of the installation manual.
Lifting
In accordance with the manual lifting of the map, in place of wood or thick cloth pad to prevent the wire rope and processing face paint bumps. In the lifting process, should be the focus of as much as possible to reduce machine tool. If the power of CNC machine tools is the separation of the tortoise, the counter top electric rings are generally used for lifting.
Adjustment
The CNC milling machine, the host is the machine shipped, the factory have a good adjustment, the user should pay attention to the installation: a hydraulic adjustment of the adjustment of self-lubricating and inspection to prevent the decline in vertical lifting platform installation, such as whether the work.
