Remember if a bench grinder is a brush-type motor you could use a rheostat or a dimmer circuit to control the speed on a pro-brand tool. Should you get a 6 or 8-inch table grinder? Most commercially available grinders have disk or wheel sizes of 6", which run at regular speed, and 8", which is better suited for a slow-speed operation.

KR804 with Sweet burrs. I do around 23g a grind and it takes 3 seconds I would guess or less. If I just cleaned the burrs, retention is around .3 to .4g for first few grinds. Then it is .2g to .3g for a month or so. Ground coffee collects around the burr screw heads, empty space in middle of lower burr and on one side of the fins that throw ...

This less severe over-speed condition can cause the wheel to be damaged, and the damage may result in breakage after further use. For example, operating a reinforced, 9-inch diameter, Type 27 wheel rated for a maximum speed of 6,600 rpm on a 7-inch angle grinder with a speed of 7,700 rpm can cause the wheel to crack.

Jan 19, 2018. #1. I am in the process of building a 2x72 belt grinder. All welded construction, using many components available online. Main question is motor speed.

Most bench grinders run at about 3,450 rpm, although there are more and more variable speed grinders on the market these days. If you're careful and keep the wheel dressed, a high speed grinder will work fine for you. However, for sharpening blades, a low-speed grinder running at 1,750 rpm is a much better choice.

If the grinder has an induction motor rather than a universal motor (with brushes and a communtator) the speed is fixed by the stator configuration and can't be changed. Those old grinders are real work horses in removing iron but too fast for sharpening tool steel.

From what I've read (and my own experience), I definitely wish this grinder to have a variable speed motor. I also know from experience that I want a motor rated around 1.5 to 2 hp (roughly 1 to 1.5 kW) and my preference would be the 2 hp motor. This desire partly comes from numerous posts on the web concerning knife grinders, for which this ...

"Motor starter capacitor" tells me that it is an AC motor in there. The fan-speed controllers "work" as the goal is less airflow, where torque is not so much of an issue. As noted by previous posters, those controllers typically reduce the torque, which can lead to stalling in a grinder.

The speed of a motor is important but can be compensated for by using the VFD to increase the motor speed or by using a larger diameter drive wheel to make up for lack of speed. Pulley, shaft and belt arrangements can also be used to compensate for motor speed. However, not all grinder designs will accept these extra moving parts.

Motor speed. Motor speed is another excellent way to judge the bench grinder performances. This is the number of wheel rotations per minute. High motor speed equals faster grinding. Motor speed varies from one bench grinder to the next. It can start from a low of 2000 RPM to a high of 3000RPM. Make sure you consider bench grinders with higher ...
