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. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.
Fine grinding produces a surface with little deformation that can easily be removed during polishing. Because of the drawbacks with grinding papers, alternative fine grinding composite surfaces are available, in order to improve and facilitate fine grinding, A high material removal rate is obtained by using grain sizes of 15, 9.0 and 6.0 µm.
This section reports a summary of the available information that can be found on technical literature about the fit tolerance between shafts and holes. The aim is to help the designer to choose the appropriate and preferred fit tacking into account the standard uses for mechanical applications. ISO and ANSI Standards The following tables report the preferred metric fits and …

Weld symbols are used to indicate the welding processes used in metal joining operations, whether the weld is localized or "all around", whether it is a shop or field weld, and the contour of welds. These basic weld symbols are summarized below and illustrated in figure 3-3. b. Arc and Gas Weld Symbols. See figure 3-3.

Complete Guide to Surface Finish Symbols, Charts, RA, RZ, Measurements, and Callouts Definition of Surface Finish. Before we get on with Surface Finish Symbols, let's understand how Surface Finish is defined. Engineering prints call out a great many things in their attempt to make sure the part that gets made matches the designer's intent.
• Interpret wheel shape and size markings together with five basic symbols of a wheel specification into description of the grinding wheel. • Given several standard, common grinding jobs, recommend the appropriate abrasive, approximate grit size, grade, and bond. The Surface Grinder is mainly used in the finishing process.

Shaft tolerances should be within ±0.05 mm (±0.002 in) and where PTFE wedge packings are used must be round within 0.01 mm (0.0005 in). Shaft surface finish should be better than 0.8 μm Ra (32 μin cla) except where PTFE wedge packings are used which require better than 0.4 μm R a (16 μin cla) and preferably a corrosion resistant surface ...
Read the label on the grinding wheels. Usually,there are items on the lables. For example use a wheel marked A36-L5-V. The A refers to the abrasive material which is aluminum oxide. The 36 represents the grain size. The L shows the wheel grade or also called degree of hardness, which is medium.

7. REPLACE grinding disks or sand-ing sleeves when worn. 8. NEVER work on more than one item at a time. 9. ALWAYS disconnect the machine from the power source before changing grinding disks, sanding sleeves, or tool bits 10. ALWAYS test run the machine before starting any work. 11. DO NOT use the flex shaft with a tight bend.

A diameter symbol (⌀) signifies a diametric zone (cylindrical tolerance zone). To specify a spherical zone, the symbol is the letter 'S' followed by the diameter symbol (⌀). In the absence of a symbol, we assume a total wide zone. The second symbol in the 2nd block gives the value of the tolerance zone in mm.
