Groofing by turning | Tasks and countermeasures for efficient grooving

This is some text inside of a div block.

The grooving process is one of the turning processing that processes a groove by applying a knife to the rotating work. There are types of grooving processing, such as "outer diameter grobean insertion", which puts grooves on the outer periphery of the work, "ender groove insertion", which puts a groove on the end of the work, and "inner diameter grooving insert" that puts a groove in the inner diameter of the work. 。 In this article, we will explain the issues generated by the lathe and the points that you want to keep for efficient grooves.

Issues generated by grooving processing

In the case of a lathe, a task of poor processing surface dignity, a decrease in chips, and a defective cut -powder processing.

Processed surface quality occurs

Groofing processing may reduce the accuracy of the processing surface. In particular, when high productivity is required, techniques such as one -shot groove processing may be taken, and in that case no finishing is performed. Also, when adding a deep groove, the amount of the part -time job protruding becomes longer and it is likely to cause chattering.

There is no life of chips

Since the grooving process is restrained, both sides of the bytes are restrained, so it is difficult to discharge cutting heat and the chip tends to be hot. If you continue to process with a hot chip, the load on the chip will increase and you may have less life than expected.

Poor cutting processing occurs

With a deep groove processing, the drainage of the powder cannot be done well. When using an external coolant to increase the emission of the powder, it may be difficult to reach the coolant in the groove and may not be able to drain the cut powder well.

Countermeasures for grooving processing by processing

We will organize the issues that occur when performing grooving processing by assignment and introduce each measure.

To improve the processing surface

In order to prevent defective processed surface quality by applying grooving, the following measures are considered. Select a chip with a chip breaker that uses a short -standing byteid ​​= "" to adopt a wiper chipSeparate the process between rough processing and finishing

Select a chip with a chip breaker

Chips are classified for finishing, medium -rough processing, and rough work, depending on the purpose and conditions of processing. In order to improve the processing surface quality, it is effective to select a tip bra with a chip breaker that promotes the drainage of the powder.

Use a short protruding byte

One of the factors in the processing surface of the processed surface product, the longer the bite protruding amount is more likely to occur. Therefore, it is important to select a short -priced part -time job. In particular, in the "inner diameter grooves", the amount of protruding tends to be longer, so care must be taken.

Adopt a wiper chip

The wiper chip is a tool that uses a wiper, a finishing blade, in the part where the corner of the blade is in contact with a straight line and a straight line, and is also called a wiper insert. It is effective especially when high productivity is required or when the sending speed is fast.

Divide the process between rough processing and finishing

By dividing the grooving process into two processes, "rough processing" and "finishing processing", it is possible to achieve both processing time shortening and quality stabilization by performing cutting -powder discharge for each process. For grooving processing used as rough processing, there are "plunged grooves", "horizontal turning processing", and "running processing".

To improve the life of chips

This section explains measures to improve the life of the chip used in grooving processing.

Considering the discharge of powder

It is effective to adopt a cutting path that takes into account the drainage emission, as the cut powder during the turning is entangled with the chip. Changing the cutting path also affects processing time and processing accuracy, so it is necessary to set a balanced setting.

Select a tool that supports high -precision coolant

For grooving processing, which is difficult to reach and tips tend to be hot, it is effective to select high -voltage high -precision coolant compatible tools. By supplying coolant as much as possible on the processing surface, the heat generation during cutting can be reduced and the chip life can be improved.

Select a tool with high wear resistance

In order to improve the life of the chip, it is important to select a coating chip that enhances wear resistance and a chip breaker to enhance wear resistance. Since the cutting performance changes depending on the chip, the point is to select an appropriate chip according to the necessary processing accuracy and work material.

To improve the defective cutting processing

In order to improve the effects of defective cutting processing, it is effective to adjust the cutting conditions and select a tool that supports high -precision coolant.

Adjust the cutting conditions

In order to properly handle the cut powder, it is effective to adjust the rotation speed, sending speed, and cut amount of the main axis. Especially by setting it to a high feed, cutting powder approaches the ideal state. On the other hand, if the sending speed is large, the load on the chip increases, so chipping may occur, so it is necessary to adjust it so that it is not too large.

Select a tool that supports high -precision coolant

Coolant is effective not only for cooling tools, but also for removal of cut powder. By selecting high -voltage high -precision coolant -compatible tools and supplying coolant on the processing surface, the defective cut powder can be improved.

Summary of issues and countermeasures for efficient grooving

In this article, we explained the issues generated by the lathe and the points that you want to keep for efficient grooves. In measures for grooving processing, it is important how to balance productivity and processing accuracy, as most measures are contradictory.
