Metal Finishing Processes Depending upon the movement of spindle or hones a machine may be vertical honing machine or horizontal honing machine. Generally honing vertical honing machines are used. Horizontal honing machines are recommended for finishing internal of long gun barrels. Lapping
Understanding surface roughness symbols. Symbols that indicate the surface texture of machined and structural parts are used in industrial diagrams. The pictorial representation using these symbols is defined in ISO 1302:2002. This section will explain how to write these symbols to indicate surface textures. Terminology explanation
Title: Surface Finish Metrology Tutorial Author: T. V. Vorburger and J. Raja Subject: Mechanical Keywords: roughness,surface finish,surface texture
Surface finish, also known as surface texture or surface topography, is the nature of a surface as defined by the three characteristics of lay, surface roughness, and waviness. It comprises the small, local deviations of a surface from the perfectly flat ideal (a true plane).
Aug 21, 2017· There are many factors that affect surface finish, with the biggest being the manufacturing process (see table above). For machining processes, such as milling, turning, and grinding, factors such as cutting tool selection, machine tool condition, toolpath parameters, feeds, speeds, tool deflection, cut width (stepover), cut depth, coolant, and ...

If you have not read "9 Basic Steps to Reading Welding Symbols" it may be worth taking a look before continuing with this post. The "9 Basic Steps to Reading Welding Symbols" focuses on fillet welds, but goes thru the basics of the welding symbol (arrow, reference .
The principal ISO standard that specifies syrface roughness is ISO 1302 and defines the surface roughness symbology and additional requirements for engineering drawings. The details in ISO surface finish standards relate to surfaces produced by abrading, casting, coating, cutting, etching, plastic deformation, sintering, wear, erosion, and some other methods.

The finish symbol reveals how to finish a weld. For example the following letters are used to convey this information on a symbol: C = chipping; M = Machining; G = Grinding; For example there is a G, as shown below, so the welder needs to grind the weld to create the contour that is needed, and the actual contour is to be ''flush''.
As for machining to iron and steel castings, the surface finish smooth degree is also an important requirement. The following is the conversion chart is from dandong foundry, for Ra (um), Ra (micro inch), Rz (um), RMS and finish degree in China and USA, including the related finish methods.
May 13, 2008· Stainless steel products are used in all parts of our daily life. Certain surface finish expectations must be met, and one of the major challenges in stainless steel treatment is meeting these expectations. The biggest problem has been the time required to rebuild the surface from a weld. While surface finishing of stainless steel still requires a good deal of effort, the proper grinding and ...
