What Is The Lapping And Define The Process

A very passive form of grinding (low pressure, low speed, low removal rate) requires the use of micronsized abrasive particles (not mesh or grit sized abrasive) some amount of movement is required on the part of the tool (lap plate), the workpiece or both; in most cases, lapping is utilized on flat surfaces, not spherical shapes or contours.

Freeform optics used in highprecision imaging requires tight tolerances for form, waviness, and roughness. microroughness needs to be less than s q 1 nm at (150 150) m 2 . to account for deviations in form and waviness, tolerances for the permitted surface deviation are split into spatial wavelength bands ranging from 1 to 16 mm with.

Grinding is a technique of finishmachining, utilizing an abrasive wheel. the rotating abrasive wheel, which id generally of special shape or form, when made to bear against a cylindrical shaped workpiece, under a set of specific geometrical relationships, will produce a precision spur or helical gear.

Specific Grinding Energy And Surface Roughness Of

Grinding, which is part of processing finishing approaches, is used to remove materials with abrasives. therefore, workpiece surface quality should be precise. grinding depth is smaller, resulting in larger specific grinding energy, compared with that of cutting and milling1,2. thus, the lubrication of the grinding surface should be considered.

In the precision grinding process a rotating abrasive wheel is used to smooth the surface of a workpiece which is typically a flat plane. parts made of ceramic, metal or plastic materials are well suited to this process which produces and extremely smooth and flat surface by removing a very thin layer of the material with each pass of the abrasive wheel.

Mechanical components such as gears and bearings operate with the working surfaces in intimate contact with a mating part. the performance of such components will be influenced by the quality of the working surface. in general, a smoother surface will perform better than a rougher surface since the lubrication conditions are improved. for example, surfaces with a special nearmirror quality.
