Abstract

The frictional forces arising on the contact of press tool with deformed metal are causes of press tool wear. Glass lubricants are used to reduce frictional forces on contact surfaces. The technological properties of glass lubricants are characterized by ability to form a lubricating layer that can withstand high loads. The article presents the results of investigation of effect of glass lubricants particle size on effective lubricating layer formation. The investigations were carried out on contact of shell inner surface with needle, on contact shell outer surface with container walls, and on contact between shell outer surface and matrix. Obtained data analysis allows to conclude that on each contact surface a certain granulometric composition of glass lubricant is required.
