7. Keep flexible electrical cords clear of oil, grease, machines and sources of heat. 8. Be aware of flying sparks. Hold grinder so that sparks fly away from you, other people and flammable materials. 9. Do not leave the angle grinder running & only use the grinder when hand held. 10.
Linear encoders for numerically controlled machine tools Linear encoders from HEIDENHAIN for numerically controlled machine tools can be used nearly everywhere. They are ideal for machines and other equipment whose feed axes are in a servo loop, such as milling machines, machining centers, boring machines, lathes and grinding machines.

Ultrasonic machining, or strictly speaking the "Ultrasonic vibration machining", is a subtraction manufacturing process that removes material from the surface of a part through high frequency, low amplitude vibrations of a tool against the material surface in the presence of fine abrasive particles. The tool travels vertically or orthogonal to the surface of the part at amplitudes of 0.05 to 0 ...
Study of Machine Tools – Grinding Machines Page 3 4.5 Grinding machine operations The process of grinding is the operation of removing excess material from metal parts by a grinding wheel made of hard abrasives. The following operations are generally performed in a grinding machine. 1. ...

By designing machines in a modular fashion, an engineer can assume power w ill be provided in a certain manner. The engineer can th en proceed with the design of the modules and elements that will transmit and uti-lize the power. This also al lows some flexibility in opti-mizing the power source as the design precedes. For
chine tool can be produced on a computer numerical control machine tool, with its many advantages. The machine tool move-ments used in producing a product are of two basic types: point-to-point (straight-line movements) and continuous path (contouring movements). The Cartesian, or rectangular, coordinate system was devised by
rotating elements of the machine Tie up long hair or wear protective hair covering to prevent hair from getting caught in the rotating elements of the machine Always hold the work piece firmly when operating this machine. Never grind loose work. Make sure to keep hands far enough away from the grinding .
A grinding wheel consists of three elements: abrasive grain, bond and pore, as shown in figure 1. As the wheel turns in high speed, its innumerable grains quickly grind workpiece to beautiful finish and precise measurement. Mechanism of grinding whetstone This process is called grinding process.

HISTORY In 1775, John Wilkinson- cannon boring machine (lathe). In 1881, Eli Whitney- milling machine. In 1947, Mr. John Parsons began experimenting for using 3-axis curvature data to control the machine tool motion for the production for aircraft components. In 1949, parsons- first NC machine. In 1951, MIT was involved in the project. In 1955, after refinements NC became available in
As with all other types of machine elements, it is important to understand the FUNdaMENTAL operating principles of different bearings in order to select the right bearing for the intended application. Indeed, the FUNdaMENTAL principles of design discussed in Topic 3 are of particular impo rtance to the proper use of bearings in machines.
