Instructor Ramesh Singh Notes Profs. Singh/Melkote/Colton Grinding Ex. 1-1 You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW.
2017 10 27 Used when cutting off stock or when milling deep thin slots Disadvantages 1 Cannot be used unless the machine has a backlash eliminator and the table jibs have been tightened 2 Cannot be used for machining castings or hot rolled steel since hard outer scale will damage the cutter Grinding Grinding is the most common form of abrasive
Higher capacity than A-G mill grinding Primary, coarse grinding (up to 400 mm feed size) Grinding media is grinding feed plus 4-12% ball charge (ball dia.100- 125 mm) High capacity (short retention time) Less sensitive to feed composition (critical size material) Semi-Autogenous Mill Note the size of the mill Why does the diameter need to be so big? image (135-6-2)
Grinding is the most common form of abrasive machining. It is a ... multipoint cutting tool with a cutting action similar to that of a milling cutter except that the cutting points are irregularly shaped and randomly distributed over the active face of the wheel. Those grains at the surface of the wheel that actually perform the cutting
8-3 Centrifugal force outward Fc mp 2 Dm 2 (8.1) is the angular velocity, mp is the mass of any particle (media or charge) in the mill and Dm is the diameter of the mill inside the liners. Gravitational force Fg mpg (8.2) The particle will remain
Grinding Process Grinding is a surface finishing operation where very thin layer of material is removed in the form of dust particles. Thickness of material removed is in range of 0.25 to 0.50 mm. Tool used is a abrasive wheel Grinding machine is a power operated machine tool where, the work piece is fed
The main uses of grinding and abrasive machining 1. To improve the surface finish of a part manufactured by other processes Examples (a) A steel injection molding die is machined by milling the surface finish must be improved for better plastic flow, either by manual grinding using shaped grinding tools, or by electro-grinding.

Working principle of Grinding Machine The working principle of a grinding machine is quite easier to understand.. In a grinding machine, there is an electric motor which supplies the motion power to the grinding wheel with the help of a belt and pulley.. So when we start the electric motor the motor rotates at a certain rpm (150-15000 RPM, it may change according to the

The hammer head should be firmly fixed to the shaft by a wedge. 2. A hammer with a worn out face should not be used. 1.3.6 Chisels Chisels are tools used for chipping or cutting metal. They are made from a good grade of tool steel and have a hardened cutting edge and bevelled head.
Lathes, milling machines, drilling machine is dependent on operator skill and training. Also a lot of time is consumed in workpart setting, tool setting and controlling the process parameters viz. feed, speed, depth of cut. Thus conventional machining is slow and expensive to meet the challenges of frequently changing product/part shape and size.
