CNC machining center efficiently completes the method of grooving.
The grooving process is a relatively complicated machining process. To do the grooving process, first understand the groove type. Common groove types are outer circular grooves, inner hole grooves and end face grooves. Although it is difficult to process, it is possible to effectively perform the grooving process by properly operating the machining center. Before that we need to understand the type of groove processing.
What is a slot? In fact, in all tool cutting, regardless of the metal and non-metal tool materials, regardless of the workpiece rotation or tool rotation processing, as long as the groove cutter is used to cut the groove on the workpiece, it can be cut Groove processing. The outer circular groove is the easiest to machine. As shown in the figure below, the outer circular groove is cut to facilitate easy chip removal under the action of gravity and coolant. In addition, the outer circular groove machining is visible to the operator, and the operator can directly and relatively easily check the machining quality. However, some potential obstacles in the design or clamping of the workpiece must also be avoided.
For the inner hole grooving, the best machining results are obtained when the tool tip position is slightly higher than the center line. The machining of the end face groove is special, the tool must be able to move in the axial direction, and the radius of the flank face of the tool must match the radius to be machined. The end face grooving tool has the best machining result when the tool tip position is slightly higher than the center line.
In any grooving process, the design and technical conditions of the machining center are also essential elements to consider. The main performance requirements for the machining center include: large enough machining power, a high-speed spindle to ensure that the tool runs in the correct speed range, and no speed or jitter occurs; there is enough rigidity to complete the required The cutting process does not cause damage to the surface finish of the workpiece due to chattering; it has a sufficiently high coolant pressure and flow rate to help the center of the main shaft of the chip removal machining center to meet the processing requirements.
When performing large-scale grooving, the selection of the tool has to be taken seriously. Chenghai Machine Tools recommends the use of forming tools. Because of the disadvantage of non-blade forming tools, if one of the teeth is damaged or worn faster than the other teeth, the entire tool must be replaced, which greatly reduces the machining efficiency and affects the machining accuracy. The forming tool can cut all or most of the groove shape by one grooving process, which can free the tool position and shorten the processing cycle time.
In fact, the sipe processing single-program design and processing process is not difficult, the complexity is the irregular shape of the workpiece and the ongoing debugging. The difference between the processing methods and the reasonable choice of the tool can be done efficiently.
