High quality parts can be produced from superfinishers by preventing grinding problems that undermine superfinishing consistency. These include excessively smooth finishes and thermal damages to the subsurface of parts. These problems be avoided by synchronizing grinding and superfinishing operations. Upstream grinders should also use free cutting wheels and process parameters that adequately prepare parts for superfinishing., Most manufacturers see grinding and superfinishing as separate operations. Unfortunately, the most meticulous superfinishing setup, using the best equipment and the latest abrasives technology, cannot correct all of the problems [...]

Line matrix printer manufacturer Printonix has adopted superabrasive grinding technology in the production of key components. Benefits of superabrasive grinding include increased tolerance and less sensitivity to coolant formulation. Grinding is also performed using a vitrified wheel due to its ability to dress various shapes in the wheel and increased grit depth which allows it to be shaped on the machine., Process parameters using superabrasive grinding for hard materials ore well known. However, this southern California shop hod o stumper of a workpiece that required grinding both aluminum and Inconel in [...]

Single point OD grinding machine, which has two axes of movement used in metalcutting processes, utilizes a wheel with a desired geometric profile dressed into the wheel where the profile is imparted to the workpiece through the machine's slide. Single point grinding accomplishes varied operations such as profiling, plunging and threading through proper control of the grinder's x and y axes. Proper application of single point grinding would be beneficial for machine shops.

Polishing and surface finishing of molds and dies is a very tedious process that requires physical hands-on effort, patience and unique skills that arc inherent with a good bench-hand or [...]

Cam-grinding operations have been adopting different techniques to improve the performance of the automobile engines they handle. One of these is camlobe grinding, an intricate variant of cylindrical grinding that involves grinding of the lobes and journal bearings, and then lapping them with fine-grit abrasive belts to minimize friction during engine break-in. Re-entrant camlobes are also gaining popularity because it allows higher engine torque and horsepower and lower emissions. Another technique is the use of composite camshafts of medium- and high-alloyed powered metal lobes placed on a hollow tube, which can endure high contract stresses and better tribological features. The use of machines with abrasive belts and high wheels speeds are other approaches used to enhance cycle time., Designs, Processes, materials, and more are discussed in this examination of a changing application area. The changing shape and composition of camshafts are challenging those responsible for surface finishing. As [...]

It sounds like a contradiction in terms--between centers and centerless grinding on one machine. But for some categories of workpieces, it's a viable production process that can yield machining time [...]

How To Take Advantage Of Double-Disc Grinding When it comes to the design of parts with flat and parallel sides, designers have been able to improve the performance of many [...]

Creep feed (CF) grinding may be the fastest method to achieve finished parts in production operations. CF is more popular in Europe than in the US because use of CF began there at the grass roots level and because early US experience with CF was less than successful. There are two basic kinds of CF grinding: conventional, in which the wheel is dressed before grinding happens; and continuous dress, in which the wheel is dressed throughout the grinding cycle. Some US machine tool and grinding wheel producers now promote the use of CF grinding technology because of its ability to grind forms or slots from the solid, because they can cut handling and set-up expenses, and because CF tooling costs are relatively low, among other reasons. Brown & Sharpe Manufacturing Co (Kingstown, RI) is one firm which processes with CF equipment, producing turbine blade specimens, barber's shears, and wrenches.

Blow molds and many prototype molds are made from aluminum. Aluminum is a very soft material and requires special polishing procedures. A fine finish can be achieved, although it may [...]

When it comes to mold polishing, every step is crucial. So, hiring the right polishing professional is a must. Mold polishers are indispensible to the life cycle of a mold--finishing [...]
