The Role of Bench Top Tribometers in Metal Working Fluids Research

The Role of Bench Top Tribometers in Metal Working Fluids ResearchThere are several manufacturing techniques like bending, deep drawing, drilling, grinding, milling, punching and cutting used for shaping the metals. The productivity of any manufacturing process will depend on the tool life and surface integrity of the finished workpiece. Therefore, metalworking fluids (MWF’s) are used in the process to reduce the tool wear and improve the surface finish of the workpiece. This is due to the performance of MWF’s as lubricants, coolants, and carriers of the wear debris. Figure 1. Images representing different manufacturing processes like cutting and drilling (left to ... Read More

Accurate evaluation of friction using Metal Forming Tribometer (MFT)

Application Notes

Accurate evaluation of friction using Metal Forming Tribometer (MFT)Automotive industry continues to develop cars that are lighter, stronger, and cost effective to manufacture using advanced high strength steels (ex. 22MnB5). Hot stamping is used to manufacture vehicle components by pressing steel blank (Al-Si, Zn-Ni coatings) above 900o C between closed dies (H13 steel) to get the final shape (Figure 1A). It is known that Volvo has approximately 40 % of its vehicle weight made of hot stamped steel. High temperatures cause excessive friction and wear between the workpiece and die tools driven by adhesive, abrasive and oxidative wear (Figure ... Read More
