JPH10264036A - Impregnation agent used for high speed cutting and grinding wheel of metal material - Google Patents

Abstract

PROBLEM TO BE SOLVED: To make possible a high speed cutting and grinding work in which the ignition by a friction heat and the surface oxization of a cut end are remarkable in a dry method, in the case of the high speed cutting and grinding of a light alloy such as magnesium and aluminum. SOLUTION: An impregnation agent consisting of an uniform mixture of a vegetable wax (or solid paraffin.polyethylene) with the minute powder of a natural graphite (or artificial graphite.carbon black) is created. By soaking this impregnation agent to the high speed cutting and grinding wheel on the market, the high speed cutting and grinding work of a light metal alloy is possible in a dry method.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to wax (or solid paraffin polyethylene) and natural graphite (or artificial graphite).
The present invention relates to an impregnating agent used for a high-speed cutting and grinding wheel for a metal material made of carbon black).

[0002]

2. Description of the Related Art Conventionally, there is no technique for impregnating a high-speed cutting and grinding wheel of a commercially available metal material or the like, and no impregnating agent is used.

[0003]

This has the following disadvantages. Among metal materials and the like, particularly in the case of high-speed cutting and grinding of light metal alloys, ignition by frictional heat and surface oxidation of cut edges are remarkable in the dry method, so that high-speed cutting and grinding work were impossible.

[0004]

SUMMARY OF THE INVENTION In order to solve this drawback, the present invention has created an impregnating agent comprising a homogeneous mixture of wax (or solid parahin polyethylene) and natural graphite (or artificial graphite / carbon black). . The problem could be solved by impregnating a commercially available high-speed cutting and grinding wheel with this impregnating agent.

[0005]

Next, an embodiment of the present invention will be described. 100 parts by weight of wax, natural graphite fine powder 30
Put parts by weight in a suitable container and heat to around 90 ° C.
After the wax is dissolved, mix well with a small electric stirring mixer. While maintaining this state, a commercially available grinding wheel is placed in a container and immersed so as to penetrate the pores of the wheel.
After several hours, the wheel is raised and allowed to cool. Thus, the grinding wheel is impregnated with the impregnating agent of the present invention. If this impregnation operation is performed in a vacuum of about 10 triceries, the immersion time of about 15 minutes is sufficient. Thus, when the grinding experiment was actually performed using the impregnated grinder, high-speed grinding was possible by the dry method. It was also found that the wet method significantly increased the grinding speed compared to the conventional method. Regarding this mechanism, the cutting / grinding wheel generally has a large number of pores and has a porosity of about 50 to 60% depending on the product, and it is easy to impregnate with the impregnating agent of the present invention. The high efficiency graphite fills the holes in the wheel, increasing the thermal conductivity of the wheel itself, synergistic effect of dissipating and absorbing frictional heat on the machined surface and lubrication by wood wax, graphite, etc. Was inferred.

【The invention's effect】

1) Light metal alloy materials can be cut and ground at high speed by a dry method. 2) Even in the conventional wet method, the use of this impregnant significantly improves the working efficiency. 3) The same effect can be obtained by using a dry belt sander. 4) When using a hand drill,
By applying this impregnating agent, the tip of the drill is not kicked.
