This is Vladimir Ramirez R&D Engineer, on the output shaft drawings appear the next roughness parameters: symbol used: Material removal by machining required Rz 16 RHSC (8) 5/cm This information came on the hole diameter of 3.5 mm with Tol: -0.013mm / -0.025 mm depth of 11 mm I need ...
Over the years the method of calculating Rz has changed, but the symbol Rz has not. As a result, there are three different Rz calculations still in use, and it is very important to know which calculation is being defined before making the measurement. In today's global economy, machined ...
If the customer actually put a microfinish symbol on the cast surface, it sounds like a design error. If the customer calls out a default finish spec for a part, it should apply to machined surfaces, only. It sounds like your profilometer is not able to measure a surface roughness greater...
aIt can be seen that the Al surface becomes quite rough (surface roughness Ra is about 3 mm) and develops mountain-like structure when the sample is anodized in a 15-wt% sulphuric acid for 2 h (Fig. 5a). 它能被看见Al表面变得相当粗砺(地面粗糙度镭是大约3毫米)并且开发山象结构,当样品在...
