How to Select a Spindle In The Loupe

24-10-2019  If you are considering using a 1 inch end mill in a material like Inconel or Titanium, a CAT50 would be a more appropriate choice. The higher the taper angle is, the more torque the spindle is capable of. While choosing the correct tool for your application is important, choosing a tool your spindle can utilize is paramount to machining success.

Speeds And Feeds For Milling With End Mills

When choosing the right parameters to run, most people focus on the speed which relates to the machine RPM. This is a mistake! Focus on on the proper feed per tooth (FPT), and then adjust the speed. Often when a part is programmed, and is being proven out for production, the programmer will choose conservative parameters and encounter chatter.

How it Works: Crushers, Grinding Mills and Pulverizers

Autogenous grinding (AG) and semi-autogenous grinding (SAG) mills use the material to be ground as the grinding media. Autogenous grinding mills use larger rocks to impact and break smaller rocks as the mill rotates. Semi-autogenous mills are basically the same autogenous mills, but with the addition of balls, similar to those in ball mills.

Modelling the influence on power draw of the slurry

01-04-2016  If one looks back over the last 70 years or so there is a fairly common theme to most of tumbling mill power draw models (Bond, 1961, Hogg and Fuerstenau, 1972, Arbiter and Harris, 1982, Austin, 1990).This is that the models used the charge shape shown in Fig. 1 in which it was assumed that all particles moved with same rotational rate and that the slurry phase was not explicitly considered.
