The company is offering an option for its model RG rolling ring linear drive assemblies; the end stop assemblies are fitted with specially machined v-shaped cams to decrease the linear speed of the drive prior to reversal without using electronic controls or reducing motor speed. After reversal, the cams permit smooth ramp up of the drive speed, eliminating whipping action of tools, such as spray heads or cutting blades. Uhing Co.http://rbi.ims.ca/4911-612
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
