Effect of rolling oil on the surface quality of annealed aluminum foils;

Experimental research on surface quality in two-dimensional ultrasonic grinding of nano-complex ceramics;

Effects of additives on the surface quality of cathode zinc;

Bye the instance of the U-bending,this paper analyses how the construction of the bending die will impact the surface finish of the bending part,proposes some construction of the U-bending die for improving the surface finish of the bending part.

The effects of α-starch on properties of moulding sand and surface finish of steel casting are studied.

A mirror surface finish on hard and brittle materials is achieved by electrolytic in-process dressing(ELID) grinding,oxide layer on the metal bond diamond wheel surface playes very important role.

The experimental results indicate that the minimum discharge voltage of piercing ascents with the increasing of blank thickness and cross section quality is better when the discharge voltage is higher than the minimum discharge voltage under the same blank thickness.

An analysis was made on the influences of big-clearance blanking to the cross section quality of the parts and to the wear of the dies.

A low temperature environment-friendly glaze formula for wine bottles was introduced, using SrO, B2O3 and BiO as the main fluxes with its fusion range between 900~1050℃, its optimal technical parameters were obtained and the effect of the preparation process on the glazing quality was discussed.
