Description

Insert tip regeneration device for face grinding {REGENERATION EQUIPMENT OF INSERT TIP FOR SURFACE CUTTING}

The present invention relates to an insert tip regeneration device for face grinding to reuse an already used insert tip, and more particularly to reshape the cutting portion of the already used insert tip to achieve the same cutting effect as a new insert tip. It is for.

In general, the insert tip is inserted into and fixed to a cutting bite shank or a milling cutter of a lathe to produce a product by cutting a workpiece such as a metal material.

In addition, the shape of the insert tip is a polygon, a cutting portion is formed at each corner is fixed to the shank of the milling cutter or bite when the used cutting edge is worn, switch to the cutting portion of the other corner and fixed, the same operation It is configured to continue.

However, the workpiece is machined using a cut formed at each corner of the insert tip, which is a polygon, so that when the cut at all the edges is worn out, the insert is replaced with a new insert tip, and the replaced existing insert tip should be discarded. Therefore, there is a problem in that the manufacturing cost of the product according to the replacement of the expensive insert tip is increased, and the environment is additionally contaminated by the disposal of the insert tip.

In order to solve this problem, Patent Application No. 1995-53295 discloses a method for reusing closed insert tips, the contents of which are as follows.

A method of reshaping and reusing worn edges after use of an insert tip having a cutting portion formed at a plurality of edges, the waste insert tip being worn in a groove of a fixing portion having a groove corresponding to the waste insert tip therein. After inserting the fixing part to the main shaft of the shelf, the tailstock provided on one side of the shelf is moved so as to be located in the center of the end of the insert tip, when the tip of the tailstock is pressed in the center of the end of the insert insert Rotating the main shaft of the lathe by operating an operation switch of the lathe, moving the tool post to a closed insert tip fixed to the main shaft when the main shaft is rotated, and downwardly from the worn cutting edge of the cutting part toward the center Characterized in that it comprises a step of grinding and reshaping with a diamond wheel, which is a cutting tool to achieve a sharp cutting angle The.

However, the method of reusing the above-mentioned waste insert tip has a problem in that it is impossible to reshape a plurality of waste insert tips in one molding process.

In addition, there is a problem that easy remolding is difficult because the molding process for reuse of the waste insert tip is complicated.

In addition, there is a problem that the risk of safety accidents are increased because the fixing of the tip for reuse of the waste insert is unstable.

The present invention has been made to solve the above problems, an object of the present invention, to enable the re-molding of a plurality of waste insert tips in one molding process.

In addition, another object of the present invention, the molding process for reuse of the waste insert tip is simple to enable easy remolding.

In addition, another object of the present invention is to secure the fixing of the tip for reuse of the waste insert tip, there is no risk of safety accidents, it does not require a high level of technology so that the non-skilled person can easily reshape the tip. .

In addition, another object of the present invention is to reduce the manufacturing cost of the product due to the reuse of the waste insert tip.

In addition, another object of the present invention is to prevent waste of resources and pollution of the environment due to reuse of the waste insert tip.
