Grinders

 

Do you buy a Silicon Carbide or a Diamond wheel?  They both do the same job and the end results are identical.  Silicon Carbide wheels are much cheaper to buy or replace than Diamond wheels, but Diamonds last many times longer.  If weight is a factor then Diamonds are the best pick.

 

What size of wheel should I buy?  The most common sizes of grinders are 4”, 6”, 8” and 10”.  The larger the grinding wheel the heavier the machine needs to be in order to stabilize the additional weight of the wheels.  Usually the larger the wheel is in diameter, the wider it becomes.  This makes it easier to work with.  As a rule, the better they are built the longer they will last.  Again, if weight is a factor then smaller is better.

 

Grinding wheels come in many grits.  Grinders are usually sold with the type of wheels assembled on them to accomplish the task they are designed for.  As an example, a four-station grinder will allow for a course grind, a medium grind, a sanding drum and a polishing unit.  The more stones on a unit, the easier it is to move from one grit (grinding wheel) to another.  A unit with two stations will require changing the wheels more frequently to finish a stone, while a grinding unit with six stations already has all the grinding stations set up and is much more convenient to use.

 

Why does the speed of the grinding wheel make a difference?  Some stones are softer than others and will wear away too fast if the wheel is turning very fast.  A smaller wheel turns faster then a larger wheel so it needs to be slowed down.   Remember, it is very important to make sure to run the grinder at the right speed and use lots of water to keep everything cool.

Why should I buy a combination saw and grinder unit?  When space is at a premium, the way to go may be a combination unit.  Everything is driven by one motor and it is all built as a single piece of equipment.  If space is not at a premium then use a grinding unit and a separate saw unit, else you may need to get the combination saw and grinder.
