To go over from the parameter h to contact ratio, the following expression should be used:
They eliminate axial thrust, prevent tilting moments and ensure silent running owing to the larger contact ratio of meshing teeth, improved distribution of heat in the tooth area.
The contact ratio is defined as the ratio between the spreading contact area of liquid over solid surface and the surface area of the spherical drop before spreading.
They have the capacity to more cost-effectively deploy the number of highly trained specialists required and the call center technology to achieve a higher right-party contact ratio.
In addition the small cutter has a smaller contact ratio with the part, reducing the tendency for chatter.
Increased contact ratio, data reporting by lead source and an online calendar system are just a few of the features that are including in the Verified Franchise Leads Program.
