when machining parts with cnc machining center manufacturers, the machining process is relatively concentrated. not long ago, eight functions of cnc machining centers were introduced. most or all processes can be completed in a single clamping process. according to the drawings of the machined parts, it is necessary to consider whether the machining of the parts can be done in the cnc machining center. if not, the machining process of the parts should be separated. the division of program processing at the cnc machining center manufacturer should be considered from the two aspects of processing accuracy and efficiency. different tools and cutting parameters are required to process different surfaces in one process. for more complex programs, the work steps can be divided in detail. work the principle of step division is described below.
1. the processing of the same surface of the machined part should be completed in the order of roughing, semi-finishing and finishing, or separated according to the principle of roughing before finishing;
2. when using cnc machining centers to process parts with milled surfaces and drilled holes, the surface can be milled first, and then drilled. this method can improve the drilling accuracy by dividing the work steps. since the cutting force in the milling process is relatively larger, the workpiece is prone to machining deformation. milling the surface first and then drilling will allow it to recover for a period of time and reduce the effect of deformation on hole accuracy.
3. according to the tool for dividing work steps of the present invention, since the rotation time of the cnc machining center table is shorter than the tool change time, the work steps can be divided according to the tool, thereby reducing the number of tool changes and improving the processing efficiency.
according to the specific structural characteristics and technical requirements of the parts, comprehensive consideration should be given to how to divide the processing procedures and working steps of the cnc machining center.
pay attention to safe operation in cnc machining
1) try to install the card stock first and then the card tool to prevent your hand from touching the tool when installing the card stock. if the tool is already installed, cnc machining center manufacturers recommend that the table should be moved outside first to ensure that it does not interfere with the tool when loading material, thereby avoiding injury or damage to the tool.
2) when removing the tool, you must first observe whether the spindle stops rotating.
3) when unloading the knife, do not hold or clamp the blade with your hands to avoid scratching the blade.
4) the wrench should be placed in the tool storage area after use, and it is not allowed to be placed on the y-axis shield or beam.
5) during the machining process of the cnc machining center, the operator is not allowed to observe the cutting position at close range to prevent the chips from falling into the eyes.
6) before turning on the oil pump switch, check the position of the nozzle to avoid spraying to other positions when flushing the oil.
7) make sure to move the table away from the cutting position when pausing for observation during machining gaps.
8) cnc machining center manufacturers remind us that after processing and before disassembling the workpiece, we must first conduct a preliminary inspection of the necessary dimensions or appearance, and the workpiece can only be disassembled after passing the inspection to avoid the positioning problems of secondary processing and scrap of workpiece after disassembly. the disassembled workpiece needs to be further checked for some key dimensional data to finally meet the machining requirements.
