Description

Cutting oil a self-oiling arrangement of a small size machine tool

The present invention relates to an automatic cutting oil supply device for a small machine tool, and more specifically, to improve the quality of products processed in the machine tool by continuously supplying the cutting oil to remove heat and residues generated during the operation of the machine tool, Accordingly, the present invention relates to an automatic cutting oil supply device for a small machine tool, which can shorten working time and is easy to install.

In general, the machine tools commonly seen around us include drilling machines, (milling) milling machines, grinding machines, grinding machines, cutters, tapping machines, etc. in various shapes and sizes.

However, such a machine tool was provided with an automatic cutting oil supply device which is installed integrally with the machine main body and can continuously supply the cutting oil to the machining part of the workpiece. However, such an automatic cutting oil supply device is fixed and requires a minimum space to be installed. As a possibility, the equipment cost was high and the economy was greatly reduced.

That is, among the machine tools, when the size is large, the cutting oil supply device was provided separately, but there was no difficulty in working, but small work places such as pipe cutters, cutters, grinding machines, etc., used in narrow or limited locations. In the case of the machine tool of the separate coolant supply was not provided.

Therefore, products working on small machine tools not only have poor quality, but also require a lot of work time.

so. Applicants have found that there is a need for an automatic cutting oil supply device that can extend the life of the tool, clean the product, reduce the working time, and is easy to install and move while considering the above various matters. This led to a proposal.

Therefore, the present invention has been devised to solve the conventional problems as described above, by continuously injecting cutting oil into a small machine tool to facilitate the work, easy installation and movement can be easily mounted through the machine tool Its main purpose is to provide an automatic cutting oil supply device for small machine tools.
