We all know that grooving is a more complex machining process in the cnc machining process, and the main thing to understand about grooving is the type of grooving. What are the common types of grooves? It is mainly divided into external groove, internal hole groove and end groove. Although the difficulty of groove processing is high, but shenzhen cnc machining factory reasonable operation of the machining center, then you can effectively complete the groove processing, before this must understand the type of groove processing.
What is grooving? Grooving is practically all cutting of tools, whether they are made of metal or non-metal tools, whether the workpiece is rotated or the tool is rotated in a machining mode, as long as the groove is removed from the workpiece using a grooved tool, it can be called grooving.
External groove machining is the easiest, and the machining form of external groove cutting is easy to evacuate chips under the action of love gravity and cooling. In addition, external circular groove machining can complete the lesson for the operator, who can directly check the quality of the relatively simple machining. However, it is also important to avoid potential obstacles in workpiece design or clamping.
However, when performing internal hole grooving, the tool blade is positioned slightly above the centerline to achieve the best machining results. When machining endface grooving special, the tool must move in the direction of the axis, and the back tool radius must be consistent with the machining radius. End face grooving tool tip position slightly higher than the center line when the best processing results.
In any groove processing, cnc machining center model design and technical conditions are also the basic elements that need to be considered. cnc machining center's main performance is as follows:
1, with a strong enough machining efficiency, a high-speed spindle can ensure that the tool runs in the correct speed range and does not drop speed or jitter.
2, CNC machining center must be required to have a high enough rigidity to complete the required cutting process, will not chatter caused by the surface finish of the workpiece damage.
3, CNC machining center needs a high enough coolant pressure and flow rate to help chip removal machining center spindle center out of the water function design can meet this processing requirements.
CNC machining center in a large number of slot processing, must pay attention to the choice of tools. Hong Wisheng precision technology recommends the use of forming tools. The disadvantage of non-blade forming tools is that if one of them breaks or wears out more quickly, the entire tool must be replaced, substantially reducing machining efficiency and affecting machining accuracy. Forming tools can cut off all or most of the groove shape with a single grooving process, vacating the tool and condensing the cycle time of the process.
In fact, the design and machining process of a single-round program for slot machining is not particularly difficult. The complication is the irregular shape of the workpiece and the consequent continuous testing to achieve the difference in processing method applied to the proper selection of tools is able to complete the cutting process efficiently.
