Jan 11, 2017· The finish of a ground plastic is extremely dependent on the following factors: Wheel Grit; Wheel grit is the most critical factor in obtaining your desired surface finish. A grinding wheel with a rougher grit will remove more material per pass, but the result is a rougher surface finish.

May 19, 2003· If poor surface finish is not discernible through tool wear and surface patterns, the second item to check is excessive heat. Discoloration of the chips, hole and tool can help pinpoint the cause of poor surface finish. When a drilling process is under control, the chips should be silver.
Surface grinding is used to produce a smooth finish on flat surfaces. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth.
Jul 25, 2015· Surface finishing process 1. MANUFACTURING TECHNOLOGY UNIT – IV SURFACE FINISHING PROCESS 2. Manufacturing Technology Grinding Grinding is the most common form of abrasive machining. It is a material cutting process which engages an abrasive tool whose cutting elements are grains of abrasive material known as grit.
A machining process that uses abrasive grinding wheels to remove surface material in order to meet precision diameter tolerances to ± .0001" and enhance surface finish (microfinish). Mirror finishes are attained via burnishing equipment dedicated for straight pins and shafts yielding 4√.
Aug 21, 2017· Surface Finish is a measure of the overall texture of a surface that is characterized by the lay, surface roughness, and waviness of the surface. Surface Finish when it is intended to include all three characteristics is often called Surface Texture to avoid confusion, since machinists often refer to Surface Roughness as Surface Finish.

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.
Our jig grinding capabilities allow us to grind straight or tapered holes up to " in diameter with tolerances as close as +/" and finishes as fine as 2 microinches. Our CNC jig grinding expertise allows us to process complex geometries to a very high degree of precision.
good surface finish are honing, lapping, polishing and surface finishing. Tolerance and range of surface roughness produced by different processes are given below. Process Tolerance (mm) Roughness (µµµµm) Grinding ± 5 to 75 Lapping ± 2 to 15 Honing ± 4 to 30 Super Finishing ± 1 to 10
Honing is an abrasive machining process that produces a precision surface on a metal workpiece by scrubbing an abrasive stone against it along a controlled path. Honing is primarily used to improve the geometric form of a surface, but may also improve the surface texture.. Typical applications are the finishing of cylinders for internal combustion engines, air bearing spindles and gears.
