The method of machining center to efficiently complete grooving

Grooving machining is a relatively complex machining procedure. To do grooving machining, we must first understand the type of groove. The common types of grooves include outer circular grooves, inner hole grooves and end grooves. Although the machining is more difficult, the reasonable operation of the machining center can effectively complete the grooving machining. Before that, we need to have a clear understanding of the type of groove machining.

What is grooving? In fact, in all tool cutting, regardless of metal and non-metal tool machining materials, regardless of the machining method of workpiece rotation or tool rotation, as long as the tool is used to cut grooves on the workpiece, it can be cut. Slot machining. External groove machining is the easiest. As shown in the figure below, the machining form of external groove cutting is convenient for easy chip removal under the action of gravity and coolant. In addition, the machining of the outer groove is visible to the operator in the whole process, and the operator can directly and relatively easily check the machining quality. But some potential obstacles in workpiece design or clamping must also be avoided.

Machining center grooving

For internal hole grooving, the best machining effect will be obtained when the tool tip position is slightly higher than the center line. The machining end face groove is more special, the tool must be able to move in the axial direction, and the flank radius of the tool must match the radius to be machined. The best machining effect is when the tip position of the face grooving tool is slightly higher than the center line.

In any grooving machining, the model design and technical conditions of the machining center are also basic elements that need to be considered. The main performance requirements of the machining center include: with sufficient machining power, a high-speed spindle can ensure that the tool runs in the correct speed range, and no speed drop or jitter; it has high enough rigidity to complete the required The cutting process will not cause chattering to cause damage to the surface finish of the workpiece; it has a sufficiently high coolant pressure and flow rate to help the function design of the spindle center of the chip removal machining center to meet this machining requirement.

When grooving in large quantities, the choice of tools has to be taken seriously.  China Cnc Machine Tool recommends using forming tools. Because the disadvantage of non-blade forming tools is that if one of the teeth breaks or wears faster than the others, the entire tool must be replaced, which greatly reduces the machining efficiency and affects the machining accuracy. The forming tool can cut out all or most of the groove shape through one grooving machining, which can free up the tool position and shorten the machining cycle time.

In fact, it is not difficult for the grooving machining to design and process the program. The complicated part is the irregular shape of the workpiece and the continuous debugging. The difference in machining methods applied to the reasonable selection of tools can efficiently complete grooving machining.
