Titanium and its alloys are considered as hardtocut substances based on [13, 17,18,19,20,21]: (1) the low modulus of elasticity; (2) the high temperature strength; (3) a small contact region is generated which results in the high stress on the cutting tool edges; (4) the poor thermal conductivity; and (5) high chemical affinity of titanium to the tools leads to builtup edge on the tools.

A. Never put a soft, ductile weld metal or a workhardening manganese alloy on top of a harder, more brittle hardfacing alloy. Deposits may spall and come loose. The softer alloy should always be applied beneath the harder deposit. Never use 7018 as a cushion or buildup. It does not have the hardness and strength for hardfacing applications. B.

Electrochemical millgrinding (ECMG) combines electrochemical milling and electrochemical grinding in one processing procedure, and can be used for machining difficulttomachine alloys. Flatness of the machined surface is a basic requirement in industrial production, and a higher degree of flatness is always preferable. However, ECMG gives the machined surface a poor flatness, which leads to ...

In Conclusion. While they both involve the physical removal of material from a workpiece, milling and grinding aren't the same. The former machining process is characterized by the use of a milling machine, whereas the latter machining process is characterized by the use of a grinding wheel. No tags for this post.

Simply put, if you want to have the option of a super fine flour, then a burr grinding mill is a good choice. An impact mill, although will get you fine flour, won't produce flour that is super fine. For bread making, a finer texture is useful for whole grains, as this will help give the bread a lighter texture.

Cooling using liquid CO 2. This arrangement as shown in Fig. 2a is made to apply liquid foodgrade CO 2 as coolant. Liquid CO 2 has been applied directly from the cylinder, through a nozzle to the grinding zone. The exit pressure was chosen as 3 kg/cm 2 enabling the CO 2 jet to effectively penetrate the stiff air layer formed around the grinding wheel and to strike the grinding zone.
