Drill Sharpener Helps Shop Hone Competitive Edge
10/14/2009 Modern Machine Shop: Bringing drill sharpening operations in-house saved both time and money at this Chicago-based manufacturer. However, the sharpener itself, Darex’s XPS-16, provided additional benefits—with high accuracy and consistent results, the machine helped the company maintain precision and quality.
Wear Compensation Ensures Accurate Wheel Contours
8/14/2009 Modern Machine Shop: Profile grinder manufacturer Blohm Jung's GEOID system automatically compensates for wear in diamond dressing tools. By removing variables that require operator attention, the system is said to ease wheel dressing, ensure accurate profiles and extend the service life of dressing tools.
Hard Turning and Grinding on a Single Machine
5/29/2009 Production Machining: Combining multiple technologies on a single machine makes the machining process more complex, but the advantages of consistent integration of such functionality can be worth the effort.
Rigidity Required When Grinding Challenging Materials
3/11/2009 Modern Machine Shop: Effective centerless grinding of hard materials requires a machine that is capable of damping process vibration at high wheel speeds and providing the rigidity to withstand very high cutting forces.
Compact Gaging System Allows In-Process Inspection On Small Grinding Machines

Overview Of:
Grinding Equipment

Grinding is a machining process that takes a very light “cut” using abrasive media—typically an abrasive grinding wheel. Grinding wheels with different grit sizes achieve rougher or finer grinding passes, according to the needs of the application. When precise accuracy and/or surface finish are required, grinding is often used as a finishing process after some other metalworking operation. Grinding is also an effective process for machining workpiece materials that are too hard for milling or turning.

Some grinders machine round parts. These machines include cylindrical grinders and centerless grinders. Some grind flat surfaces. These are surface grinders. Form grinders move the work and/or the wheel in various axes to grind surfaces that are precisely contoured.

Still other grinders are dedicated solely to machining the hard materials necessary to produce cutting tools for other types of machining operations. These are referred to as tool grinders or cutter grinders.
