Abstract

PURPOSE:To prevent troubles caused in removing cut chips so as to permit the full automatization of a machining line by breaking cut chips in small pieces through jetting ultra high pressure cutting oil to portions to be cut, in the case of disposing process of chips cut by a lathe, a drill, etc. CONSTITUTION:In the case of, for instance, a lathe, a nozzle 13 is arranged opposite to the blade tip 12 of a cutter 11 and is connected in continuity to an ultra high pressure generating pump through a high pressure hose 14. Then, in cutting a workpiece 15, cut chips 16 are cut through jetting ultra high pressure cutting oil from the nozzle 13 to a chips producing portion 17 in the direction opposite to the cutting direction. This method is effective in automatizing a machining line. And it is possible to cope easily with changes of cutting conditions by only simple adjustment such as the control of jetting pressure for cutting oil etc. Furthermore, cutting oil used originally for cooling is used for cutting and no other liquid is used, therefore effective use of cutting oil can be accomplished.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for processing a cut H cut by a lathe, a drill, or the like.

[Conventional technology]

In general, cutting operations using machine tools such as milling cutters, drills, end mills, and lathes are becoming more and more fully automated, as FMS (Flexible Manufacturing Systems) are being called for in a wide range of applications.

The cutting chips generated by these machine tools vary depending on the processing method and the material of the workpiece, ranging from fine sludge-like particles to relatively fine curls or large-diameter curls. , having unique dimensions, shapes, and properties.

During cutting, relatively long curled chips and large-diameter curled chips become entangled with each other during conveyance from the place where chips are generated to the place where chips are discharged, to a central coolant filtration device, or conveyed by a dip conveyor. The particles grow into a large dumpling shape, which significantly obstructs transportation or causes damage to part of the structure during transportation, which is a hindrance to automating the entire system.

In such cases, conventionally, a chip breaker is used to mechanically cut off the cutting chips.

[Problem that the invention seeks to solve]

However, since this chip breaker is mechanical, its shape must be changed depending on the cutting conditions, and changing the shape is not easy.

An object of the present invention is to provide an effective method for cutting cutting chips non-mechanically.

[Means for solving problems]

The present invention resides in a cutting swarf processing method that injects ultra-high pressure cutting oil to the cutting swarf generating portion 17 of the workpiece 15 to cut the cutting swarf 16.

[Effect]

The present invention immediately breaks the cutting chips 16 into small pieces by injecting ultra-high pressure cutting oil to the cutting location, prevents 1-rub when discharging the chips, and provides a solution to complete automation.

[Actual drop example]

Hereinafter, the present invention will be explained in detail with reference to the drawings and examples.

For example, in a lathe, a nozzle 13 is disposed opposite to a cutting edge 12 of a cutting tool 11. This nozzle 13 is connected via a high-pressure hose 14 to an ultra-high pressure generating pump consisting of a booster (not shown) or the like. This ultra-high pressure generation pump sucks cutting oil from a cutting oil tank and supplies ultra-high pressure cutting oil of 10 to 15 degrees of pressure per cd or more to the nozzle 13.

Then, when the workpiece 15 is cut by the cutting tool 11, cutting chips 16 are continuously generated from the workpiece 15.
7 to 1000 from the direction opposite to the cutting direction 9 /
Cutting chips 16 are cut off by spraying ultra-high pressure cutting oil of ci or higher.

The injection method may be to continuously inject the ultra-high pressure cutting oil to the chips 16 that are being continuously cut, or to repeatedly inject the ultra-high pressure cutting oil intermittently. Good too. By doing so, the cutting chips 16 are torn off by the jet of ultra-high pressure cutting oil.

In this way, the chips 16 are cut to a size that does not impede the conveyance, and then are fed onto the chip conveyor or forced out, and then transported to the coolant filtration device or an external discharge location, so that this kind of machining line is suitable for this type of machining line. This is effective in achieving complete automation.

On the other hand, the injected cutting oil is regenerated by the filtration device and then circulated back to the suction side tank of the ultra-high pressure pump.

〔Effect of the invention〕

According to the present invention, since ultra-high pressure cutting oil is injected into the part where cutting chips are generated in the workpiece to cut the cutting chips, simple adjustments such as adjusting the injection pressure of the cutting oil can be made. Changes in cutting conditions can be easily accommodated with a chisel. In addition, cutting oil, which is normally used for cooling, is used for cutting chips, and no other liquid is used, so cutting curves can be used effectively, and a built-up edge that gets hot due to cutting process can be avoided. can be held down effectively.
