Tapered and contoured surfaces require both modes of tool feed at the same time, often referred to as ...
A chuck is a specialized type of clamp used to hold an object with radial symmetry, especially a cylinder.In a drill or a mill, a chuck holds the rotating tool; in a lathe, it holds the rotating workpiece.. Chucks commonly use jaws to hold the tool or workpiece. The jaws (sometimes called dogs) are typically arranged in a radially symmetrical pattern like the points of a star.
Lathe chucks are used to accurately clamp a workpiece on a lathe for turning operations or can be used on an indexing fixture for milling operations. Manual lathe chucks manually open or close jaws with a screw or pinion. Power lathe chucks use hydraulics, pneumatic or electricity to close the jaws. They have a high gripping accuracy and are designed for mass production.
compress the material on the outside which will then give the inside more grip. Put a cloth around the top of the visor to protect the material and use Mole grips with the half circle jaws or pliers of the same construction grips to squeeze the area around where the rod enters the visor.
