The various technological solution offered by C.O.S.M.A.P. for the automatization of the grinding, deburring and satin finishing processes, are based on the employment of the rotary table and its great efficiency when interfaced with our various models of working unit, or when integrated into a robotic isle.
Milling Machine Definition: The milling machine is a type of machine which removes the material from the workpiece by feeding the work past a rotating multipoint cutter.The metal removal rate is higher very high as the cutter has a high speed and many cutting edges. It is the most important machine in the tool room as nearly all the operations can be performed on it with high accuracy.
These grinding machines are designed to sharpen milling cutters, reamers, taps and other machine tool cutters. The general-purpose cutter grinder is the most popular and versatile tool-grinding machine. Various attachments are available for sharpening most types of cutting tools. Jig grinding machines.
OBJECTIVE :To study the characteristic features of lathe. OUTLINE OF PROCEDURE i) Run the machine at low speed and observe the motions, which control the shapes of the surfaces produced. Note particularly the features, which control the geometrical form of the surface. ii) Learn the names of the major units and the components of each machine.
automatic machines usually yield better-quality, faster, more reproducible results. Manual grinding allows better control of grinding depth than au-tomatic grinding, which could be important when the cross section at a specific depth is of interest. Automatic equipment is much more expensive than manual machines.
In grinding, abrasives are held rigidly by hard (solid) bond material, whereas in AFM abrasives are held by semisolid bond (or medium). In all these abrasive finishing processes, the grain-workpiece interaction involves one or more of the basic modes of material deformation, i.e., cutting, ploughing and rubbing.
