Electrical Discharge Machining (EDM) | Modern Machine Shop
2021年7月10日 · Electrical discharge machining, or EDM, is a non-contact process that can machine parts regardless of their hardness. It involves placing an electrode or wire and an electrically conductive workpiece into a circulating dielectric fluid. The fluid acts as an insulator until a specific spark gap and voltage ionizes it and enables a spark to ...
Choosing The Right Grinding Wheel | Modern Machine Shop
2000年12月15日 · Another factor that affects the choice of wheel bond is the wheel speed in operation. Usually vitrified wheels are used at speeds less than 6,500 surface feet per minute. At higher speeds, the vitrified bond may break. Organic bond wheels are generally the choice between 6,500 and 9,500 surface feet per minute.
Properly Reading Dial Indicators | Modern Machine Shop
2021年5月6日 · Properly Reading Dial Indicators. Dial indicators provide useful readings about tolerance ranges at a glance — but new users need to know how to set up these indicators before using them. Dial indicators have been around since the early 1900s, and, while digital indicators may be gathering more attention recently, dial indicators are unlikely ...
How to Correctly Measure Surface Finish | Modern Machine Shop
2021年12月21日 · When measuring surface roughness, the first step is to filter out the waviness component from the roughness component. This is done by breaking the total measuring length of the surface finish measuring stroke into small segments, called cutoff length. Typically, the default cutoff length is set at 0.8 mm. When using this cutoff length on these ...
Machining Centers | Modern Machine Shop
2024年10月2日 · Machining Centers. The term “machining center” describes almost any CNC milling and drilling machine that includes an automatic toolchanger and a table that clamps the workpiece in place.
