IPC: B21J3/00
Filed: 1989-10-04
Abstract: PURPOSE:To improve the adhesive property of lubricant and to prevent a die from being clogged with the residue by tumbling the stock coated with solid lubricant and adjusting an adhered quantity of lubricant on the surface of the stock. CONSTITUTION:The lubricant 4 is adhered to the ground coating film 3 formed on the work base 2 of a work 1. The surface of the lubricant adhered is ground to adjust the adhesive quantity of the lubricant to a specified quantity by tumbling the stock 1 coated with lubricant 4.

The residual lubricant adhered by friction between the works to the surface is removed. In this way, a quantity of lubricant excellent in adhesive property and necessary and sufficient for working can be adhered. Further, as the die is prevented from being clogged with the lubricant residue, the adhesive quantity of the lubricant can be adjusted in accordance with draught and the adhesive property can be improved.
