METHOD FOR DIAMOND-COATING BOTH SIDE SURFACES OF INSERT AND DIAMOND-COATED INSERT MANUFACTURED BY SAME METHOD

摘要

The present invention pertains to a method for diamond-coating and a diamond-coated insert manufactured by the same, wherein a relatively uniform coating film may be formed on the both side surfaces of an insert for a cutting tool by carrying out the diamond-coating, which has been conventionally carried on one side surface of the insert because of economic problems, on the both side surfaces at low cost such that the utility of the insert may be increased. The method for diamond-coating according to the present invention performs diamond-coating while rotating one or more inserts in a CVD device such that the diamond-coating layer may be formed on the both side surfaces of the inserts.
