The drilling machine is defined as a machine which is used to make a circular hole, a tool used to drill the holes of different size and other related operations using a drill bit.. The drilling machine is one of the most important machines in a workshop. As regards its importance it is second only to the lathe machines.Holes were drilled by the …

The chuck is a mechanism used to grip the tool tightly enough to stop the tool from slipping during drilling operations. A drill chuck typically has three jaws whose position can be adjusted to account for different drill bit diameters. When adjusted, these jaws move either radially inwards or outwards to account for different diameters. 9.

It is used for holding the bars of small sizes (below 63mm). Magnetic chuck: They are of permanent magnet type or electrically operated. In lathe it does not have a widespread use. Feed Rod: Feed rod is a power transmission mechanism used for precise linear movement of the carriage along the longitudinal axis of the lathe.

What is a Gear Grinder? Gear grinders are finishing machines that use a grinding wheel rotating at high speed to grind the surface of the gear (workpiece) teeth. ... together with a mechanism for exchanging the workpiece as soon as grinding is complete (see Fig. 14). Indexing is the preliminary setup to ensure that the phase of the grindstone ...

A grinding machine is machine tools which is used for removing of rough surface of a workpiece with the help of rotating abrasive wheel that acts as a tool. or An …

Such wheel is used in grinding machine. The grinding effect of wheel periodically releases individual grains of abrasive. The wear in this process is predictable and measurable for good performance in metal surface finishing. ... Scotch Yoke Mechanism: The scotch yoke mechanism is a reciprocating motion mechanism, is …

Explanation: A quick return mechanism converts the circular motion into reciprocating motion (repetitive back-and-forth linear motion).; This mechanism is mostly used in shaping, planning, and slotting machines.; In slotting, the rotary motion of the drive is converted into the reciprocating motion of the ram by the mechanism housed within …

Abstract. Grinding of metals is a complex material removal operation. Research on cutting process of a single abrasive grain is the basis of further understanding of grinding mechanism. In this ...
