We offer custom-made stainless steel spiral augers for meat grinders based on drawings or samples. We can evaluate solutions for silica sol precision casting, shaft end CNC machining, and mass delivery by considering factors such as spiral outer diameter, pitch, shaft end interface, coaxiality, material, and purchase quantity.
Machining allowances in precision casting are not fixed values. This article explains how to determine the machining surfaces and allowances for stainless steel castings from blank to CNC finished product, starting from machining datum, casting structure, dimensional tolerances, deformation risks, and clamping methods.
In procurement drawings, quality reports, or surface treatment requirements for precision-cast and CNC-machined parts, terms such as Ra, Ry, Rz, and polishing levels are frequently seen. While all related to surface finish, they are not the same concept. Choosing the wrong indicator may result in parts that, although "appear shiny," fail in sealing, fit, wear resistance, or coating adhesion. This article, starting from the practical applications of stainless steel precision casting and CNC machining, compares surface roughness indicators, common polishing conditions, metal wear risks, and subsequent surface treatment selection strategies. I. Surface Finish…
