Introduction to Universal Grinding Machine



Grinding:
Grinding is a process carried out with a grinding wheel made up of abrasive grains for removing very fine quantities of material from the work piece surface. The required size of abrasive grains are thoroughly mixed with the bonding material and then pressed into a disc shaped of given diameter and thickness. Grinding process is used for two reasons
(i)        Higher value of surface finish and accuracy that cannot be provided with the machining process.
(ii)      Hard and brittle materials that cannot be machined or it is uneconomical to use machining 
Grinding wheel
A grinding wheel is made of abrasive grains held together by a bond. These grains cut like teeth when the wheel is revolved at high speed and is brought to bear against a work piece. The properties  of a wheel that determine how it acts are the ginding parameters including the kind and size of an abrasive matereial, how closely the grains are packed together and the type and amount of the bonding material.

Operations Performs on Lathe Machine

Image
Facing Facing is the process of removing metal from the end of a workpiece to produce a flat surface. Most often, the workpiece is cylindrical, but by using 4- jaw chuck we can face rectangular or odd-shaped work to form cubes and other non-cylindrical shapes. When a lathe cutting tool removes metal it applies considerable tangential (i.e. lateral or sideways) force to the workpiece. To safely perform a facing operation the end of the workpiece must be positioned close to the jaws of the chuck. The workpiece should not extend more than 2-3 times its diameter from the chuck jaws unless a steady rest is used to support the free end. Straight turning In this operation the work is held in the spindle and is rotated whole the tool is fed past the work piece in a direction parallel to the axis of rotation. The surface generated is a cylindrical surface. Taper Turning A taper may be defined as a uniform increase or decrease in diameter of a work piece measured along its length...

Tool Holding Devices in Drill Machine

Image
Tool-Holding Devices: Drill press spindle provides means of holding and driving cutting tool.End may be tapered or threaded for mounting drill chuck. Most common devices are used in Drill presses:       Drill chucks       Drill sleeves        Drill sockets Drill Chucks: Most common devices used for holding straight-shank cutting tools. Most contain three jaws that move simultaneously when outer sleeve turned. Hold straight shank of cutting tool securely. Two common types               Key   Keyless     Drill sleeves:                        Used to adapt cutting tool shank to machine spindle if taper on tool is smaller than tapered hole in spindle   Drill sockets: ...

Parts of Vertical Milling Machine

Image
Parts of Vertical Milling Machine The vertical knee mill is the most common milling machine found in machine shops today. Therefore it will be used as an example to describe the general parts of all mills. Head                The head (drive) is that part of the drive system that transforms electrical power from a motor to mechanical power in the spindle. The drive system also allows the machinist to change the speed of the spindle (RPM) and therefore the cutting tool. The quill moves vertically in the head and contains the spindle in which cutting tools are installed. Column                The column is the most important part which is mounted on the base and acts as a support and holding device for all the other parts of a milling machine. It acts as a support for table and all feed mechanisms. The column should be rigid enough to sust...
