From job shops to tool and die makers surface grinding is an important machining technology no matter what you make.
Whether its used to square up a punch sharpen a cutting tool or precisely shape tool steel for a fixture every shop has at least one surface grinder. Perhaps you have a fully automated model with all the bells and whistles. Or maybe you are working with a hand-me-down grinder from the 70s Either way it would be impossible to perform many everyday shop tasks without these much-needed machines.
Despite their familiarity however are you sure that youre taking full grinding advantage of this machine shop companion Heres a primer on how to get the most out of your surface grinding operation.
Lets start with the wheels A bewildering variety of grits abrasives bonding mechanisms and shapes exist and some shops might settle for a general purpose wheel rather than investigate which of the many combinations will work best for a specific application. Heres what you need to understand to make surface grinding an efficient and effective process.
A relatively soft Grade H wheel is preferred for grinding harder workpiece materials while a Grade J or K which are harder could be more suitable for soft materials. Taking a few minutes to switch from one to the other might make a huge difference in the number of parts sitting on the bench at the end of the day.
When removing large amounts of material using a 120 or coarser grit will get the job done more quickly than say a 150 grit wheel. And while vitrified bond aluminum oxide wheels are the go-to for general purpose work shops grinding hardened tool steel and other difficult materials should consider investing in a resin bond ceramic or CBN wheel.
These examples are a gross simplification as the performance of any grinding wheel depends on a variety of factors including the type of abrasive the material being cut and how much of it is being removed. The point is to research your available options and not settle for second best during the grinding wheel selection process.
Once you have the right wheel cutting fluid and a rigid setup here are a few more tips to have you grinding successfully
Its important to remember that surface grinding works by tearing away small bits of metal and the cutting fluid is responsible for providing lubricity as well as pulling heat away from the work zone. Water-soluble or synthetic cutting fluids do a great job at cooling things down but provide less lubricity than straight oil. Still water-based coolants are probably the first choice for general purpose use and certainly for roughing operations where heat is a major concern.
