FANUC cnc 1165 price and selection and matters needing attention:
In the technological transformation of enterprises, in order to improve competitiveness, machining centers are always given priority, and they all hope to obtain high-precision, powerful, and reliable machine tools with the least investment. Due to the large one-time investment and complex technology of the machining center, it causes a lot of inconvenience for users to select and order; at the same time, price, function and precision are an opposite unity. Therefore, how the user chooses a suitable machine tool is very important. Machine tool selection is not only a practical comprehensive application technology based on machine tool technology and processing technology, but also an application technology constrained by its own economic strength. The selection of machining center is much more expensive than ordinary machine tools, so it is subject to more restrictive factors, and whether the machine tool selection is reasonable or not is more prominent. The correct selection is the key to making good use of the machining center and making the machining center effective. 1 Selection procedure Correct and comprehensive understanding of the machining center is the basis for selection and ordering. It is necessary to have a comprehensive and detailed understanding and mastery of the performance, characteristics, types, main parameters, functions, scope of application, and deficiencies of the machining center. On the basis of full understanding, it can be carried out according to the following procedure.
Correct selection of processing objects Select typical processing objects among the many parts produced by the enterprise, that is, part family selection. The processing center is suitable for multi-variety, small batch production. The batch formation is not only determined by the geometric size and quantity of the parts, but also the maturity of the process should be considered. The use of group technology can effectively increase the processing batch of similar parts to approach the efficiency and benefit of mass production, and realize medium and small batch production. Whether the selection of the part family is appropriate or not has a very important impact on giving full play to the investment benefits.
Develop process plan Perform process analysis on typical parts (main samples) of the determined part family, and formulate process plans. Select machine tools with specifications, accuracy, and functions that meet the requirements, and consider the future development of the enterprise to determine whether or not functions are reserved. At the same time, the processing time of the machining center is high. When considering the process load, not only the possibility of machine tool processing, but also the economics of processing must be considered.
2 Selection
The type selection considers the processing technology, the best processing object of the equipment, the scope and the price and other factors, and selects according to the selected part family. For example, the processing of workpieces with more than two sides, or the processing of pores and surfaces arranged radially around, such as various boxes, should choose a horizontal machining center; single-sided processing of workpieces, such as various plate parts, etc., A vertical machining center should be selected; when processing complex curved surfaces, such as air guide wheels, integral impellers on engines, etc., a five-axis machining center can be selected; the position accuracy of the workpiece is required to be high, and a horizontal machining center is used. When multi-face machining needs to be completed in one clamping, a five-face machining center can be selected; when the workpiece size is large, such as a machine bed, column, etc., a gantry machining center can be selected. Of course, the above-mentioned points are not absolute, especially as CNC machine tools are developing in the direction of compounding. In the end, the decision must be made under the conditions of process requirements and capital balance.
Parameter selection The most important parameters of the machining center are the size of the worktable, etc., which are selected according to the typical parts of the determined part family.
Worktable size This is the main parameter of the machining center, which mainly depends on the outline size and clamping method of typical parts. A workbench slightly larger than typical parts should be selected to leave the space required for the installation of fixtures. The load-bearing capacity of the worktable should also be considered. If the load-bearing capacity is insufficient, the size of the worktable should be increased to increase the load-bearing capacity.
The stroke of the coordinate axis The most basic coordinate axes are X, Y, Z, and the stroke has a corresponding proportional relationship with the size of the worktable. The size of the workbench basically determines the size of the processing space. If the size of the individual workpiece is larger than the machine coordinate stroke, the processing area of the workpiece must be within the stroke range of the machine tool.
Spindle motor power and torque It reflects the cutting efficiency of CNC machine tools, and also reflects the rigidity of the machine tools from one side. For different machine tools of the same specification, the motor power can vary greatly. Comprehensive consideration should be made according to the workpiece blank allowance, the required cutting force, machining accuracy and tools.
Spindle speed and feed speed When high-speed cutting or ultra-low-speed cutting is required, the speed range of the spindle should be paid attention to. Especially for high-speed cutting, it is necessary to have a high spindle speed and a feed speed that matches the spindle speed.
