Description

An insert tip grinding method {Insert Tip Grinding Method}

The present invention relates to an insert tip grinding method, and more particularly, to an insert tip grinding method capable of stably and accurately performing insert tip grinding when performing grinding on a plurality of insert tips.

Machine tools such as a lathe, a shaper, a miller, and a boring machine are generally used for machining a workpiece made of a metal into a desired shape by a cutting chip. In a machine tool, It is well known that a cutting tool of the present invention is installed.

The cutting tool may be divided into various types according to the machine tool. For example, a fixed tool type in which a cutting tool is fixed while rotating a workpiece such as a lathe, a shaper, or a flatener, and a fixed tool type in which a workpiece is fixed, such as a milling machine, a boring machine, And a rotary tool type having a shape in which a cutting tool rotates while being placed in a position.

Here, the cutting tool of the fixed tool type is a cutting bite used in combination with a machine tool such as a lathe. Typical cutting tool configurations include a tool holder having a certain length so as to be installed in a machine tool, (For example, a DNMG insert tip, etc.), a grooving tool, a tool holder, and the like, depending on the application and the shape of the workpiece to be cut. It is classified into various insert tips such as for threading.

Meanwhile, the insert tip according to the prior art is manufactured as a blade portion which comes into contact with a workpiece from a cutting tool, and is manufactured in an assembled manner so that it can be easily replaced when it is worn or damaged.

However, the conventional cutting tool has a problem in that it is necessary to manufacture cutting tools separately according to the processing and form of the workpiece. This is not only unnecessarily costly, but also requires a lot of work and low productivity, resulting in an increase in manufacturing cost, because the cutting tool needs to be manufactured differently in accordance with different structures of the tool holder as well as the insert tip as well as the insert tip.

In addition, the insert tip according to the prior art has a mounting surface formed on one side for assembling the cutting tool. The mounting surface of the insert tip must be ground to satisfy the roughness and flatness within a predetermined range to be firmly assembled to the cutting tool.

FIG. 1 is a schematic view showing a state in which an insert tip is ground using a cutting tool according to the prior art.

In the case of a cutting tool according to the related art, an insert tip to be machined is mounted on a tip seating frame 90 formed in a bed part 40, and then a grinding operation is performed using a grinding wheel 110.

However, in order to stably fix the cutting tool according to the prior art to the tip seat frame, a plurality of fixing parts must be separately manufactured and mounted.

FIG. 2 is a plan view, a side view and a sectional view showing an insert tip according to the prior art.

As shown in FIG. 2, the insert tip 10 is formed with the side surface 12 of the inclined structure and has both end portions P1, P2 - P3, and P4 having different heights from the ground surface on the side surface, It can not be stably fixed using a device such as a vise tool of a general rectangular structure.

When the insert tip shown in Fig. 2 is placed on a flat surface, only portions P1 and P2 having a relatively long height are tilted to one side after coming into contact with the ground. As a result, the insert tip needs a separate fixing member to be stably mounted on the ground.

In some cases, when the allowable range of the value of the surface roughness after polishing of the mounting surface 13 of the insert tip 10 is within 1 to 100 micrometers, the insert tip should be more stably fixed.

Therefore, as shown in FIG. 1, only one insert tip was fixed using various kinds of fixing parts, and then the grinding operation had to be performed.

However, such a grinding method has a problem in that it takes a long time to fix the insert tip and perform the grinding operation. Furthermore, when performing a grinding operation on a large number of insert tips, the time required for the grinding operation increases exponentially.

Accordingly, there is a need for a technique capable of solving the problems of the above-mentioned prior art.
