Abstract

A wet type buffing method is practiced such that a final buffing step is conducted in a buffing liquid having alkality and the remaining buffing steps are conducted in other buffing liquid having acidity. A work buffing apparatus is constructed such that a disconnection preventive member is disposed at the foremost end of a shaft for a work, the outside of a buffing wheel comes in contact with the disconnection preventive member, a tightening nut is threadably engaged with the buffing wheel, and the buffing wheel is tightly fixed to the shaft by displacing the tightening nut along the shaft. In addition, a surface treatment conducting method is practiced such that each surface treatment is conducted after a work is subjected to barrel buffing before or after the surface treatment. Additionally, a work supporting apparatus includes a buffing medium receiving container having a buffing medium received therein and a work supporting arm. Further, a buffing medium employable for a buffing apparatus is composed of grain of soft material or small block of the soft material.

Benefits of technology

[0021] The present invention has been made in order to eliminate the inconvenience inherent to the first conventional technique as mentioned above. Therefore, a first object of the present invention is to provide a wet type buffing method which assures that an operational efficiency of each wet type buffing operation can be improved via a series of buffing steps, and consequently, each work can smoothly be buffed (hereinafter referred to as "a first invention").

[0022] In addition, the present invention has been made in order to eliminate the inconvenience inherent to the second conventional technique as mentioned above. Therefore, a second object of the present invention is to provide a deposition plating method which assures that the thickness of a deposition plated layer can be reduced in excess of the thickness obtained by the conventional deposition plating method, each deposition plating process can quickly be practiced, and consequently, an operational efficiency of each deposition plating operation can be improved for each buffed work in association with the quick execution of the buffing process (hereinafter referred to as "a second invention").

[0023] Additionally, the present invention has been made in order to eliminate the inconvenience inherent to the third conventional technique as mentioned above. Therefore, a third object of the present invention is to provide a work buffing method which assures that dirty foreign matters adhering to the surface of a work to be buffed and an oxide film extending over the surface of the work can easily be removed, thereafter, the surface of the work to be buffed is subjected to dry buffing, and subsequently, the surface of the work can be subjected to dry buffing (hereinafter referred to as "a third invention").

Problems solved by technology

However, with respect to the conventional buffing method as mentioned above, in the case that a buffing agent having acidity is used like the first-mentioned conventional buffing method, the buffing efficiency can be improved but there appears an inconvenience that it is appreciably difficult to smoothly buff each work.

On the other hand, in the case that a buffing agent having alkality is used like the last-mentioned conventional buffing method, each work can smoothly be buffed but an oxide film or the like remaining on the surface of the work can be removed from the work only with much difficulties.

As a result, there appears an inconvenience that it is difficult to improve the buffing efficiency with the conventional buffing method.

However, with respect to the first-mentioned conventional buffing method, since dry type buffing is employed as buffing means, the buffing time can be shortened but the resultant buffed surface of the work exhibits poor surface roughness with a reduced degree of brightness.

Consequently, there arises an inconvenience that the thickness of a deposition plated layer should be increased, and moreover, it is practically difficult to improve the operational efficiency of each deposition plating operation performed for the work.

As a result, the thickness of deposition plating can be reduced but the time required for performing each buffing operation is undesirably elongated.

For this reason, an inconvenience arises in the same manner as mentioned above such that it is practically difficult to improve the operational efficiency attained by the deposition plating process with each buffed work.

However, when the conventional buffing method as mentioned above is employed for the purpose of buffing each work, this work is subjected merely to wet buffing in the presence of an acid detergent liquid.

For this reason, there arises an inconvenience that dirty foreign matters are removed from the surface of the work with some difficulty, and moreover, it is practically difficult to remove an oxide film from the surface of the work due to the substantially intense strengthening achieved for the work in the presence of the acid detergent liquid.

However, when the conventional buffing method as mentioned above is employed, the surface of the work to be buffed is oxidized during each buffing operation, causing an oxide film to be readily formed on the work.

As a result, there arises an inconvenience that it is practically difficult to improve a quality of each buffing operation.

Consequently, there arises an inconvenience that it is practically difficult to improve the operational efficiency attained by the buffing operation.

As a result, there arises an inconvenience that it is practically difficult to determine the position assumed by each buffing wheel 520 relative to the work W.

However, with the conventional barrel buffing apparatus constructed in the above-described manner, since an operational extent attained by the buffing medium is limited within a certain range by the buffing medium, it is required that the buffing medium is replaced with other one in dependence on an object of each buffing operation, i.e., a rough buffing step, an intermediate finish buffing step and a final finish buffing step, and alternatively, it is required that a plurality of barrel buffing apparatuses each including a buffing medium selected in such a manner as to match with a certain object of the conventional barrel buffing apparatus are preparatively arranged.

At any rate, there arises an inconvenience that it is practically difficult to improve an operational efficiency of each barrel buffing operation with the conventional barrel buffing apparatus.

However, with the foregoing conventional technique, each work is subjected to buffing merely by using operator's hands.

Consequently, there arises an inconvenience that an operational extent attained by each buffing operation readily fluctuates, resulting in each coating operation being unavoidably performed with some fluctuation.

In addition, since it is required that burrs formed on the work because of a necessity for correctly performing each coating operation are removed from the work, there arises an inconvenience that it is practically difficult to improve the operational efficiency attained by employing the foregoing conventional technique.

However, with the conventional barrel buffing apparatus, since each work is dipped in the barrel buffing medium received in the buffing medium receiving container while it is seized with the aid of a certain seizing instrument, there arises an inconvenience that it is difficult to hold the work in the immovably seized state.

In addition, there arises an convenience that it is difficult to attach the work to the seizing instrument and detach the work from the seizing instrument.

Especially, in the case of a work having a large mass, the last-mentioned inconvenience appears remarkably.
