#0183;#32;This may not be the quot;standardquot; way surface grinding wheels are checked for balance, but it seems to work for me. Since the 1960''s I''ve had a quot;Magna Matic mower blade balancer. Mine is the original version which according to the spec sheet is supposed to be able to detect an out of balance situation as small as 2 grams.
1, first of all, balance the equalizer bar of the grinding wheel with horizontal level, Then,mount the grinding wheel on the mounting sleeve, Fix special shafts for balancing grinding wheels in the mounting sleeve. Arranged the balance shaft on the balance frame of the grinding wheel;
#0183;#32;Surface Grinding Wheel Balancing. To craftsmen who do work with tiles, wood, stone and others, grinders are precious to them. Surface grinding wheel must maintain its balance to keep its safety and good functionalities. There are some selected balancing devices used to balance the wheel by using balancing weights connected to the outer part and determine the best balance position.
#0183;#32;In this video I balance a surface grinder grinding wheel on the balancing frame and arbor from the previous videos.
Grinders are invaluable to craftsmen who work with wood, tiles or stone. To maintain safety and proper functionality, the grinding wheel must be kept balanced. A balancing arbor can be used to balance a grinding wheel. A balancing arbor uses a pair of collars between the grinding wheel in which balancing weights are

In recent years we have seen an increase in the rotation speed of grinding machine spindles, along with the capacity of achieving superior levels of surface finish. With such levels of performance the vibrations caused by the imbalance of mechanical parts and the grinding wheel

#0183;#32;I think I have a easier way by using only 2 balance weights. 4. Place the wheel and arbor on the balance stand with out the balance weights. The heavy side will end up at the botton. Mark the light side (top) with a marker pencil. 5. Remove the wheel and arbor and place two balance weights half way between the light and heavy side at 90 degrees apart. 6.
#0183;#32;I just spoke w/ a guy who has 40+ years in a machine shop doing a ton of surface grinding and he assured me that whatever the dimension of the wheels if you want micron finishes you must balance the wheels (not that you are saying not to, just saying this for others)... but he also informed me that I can balance by just remove a little material off of the side of the heavy side of the wheel
#0183;#32;A surface grinding process is performed on an aluminum part. The grinding wheel with 100 grit size and outer diameter of 250 mm moves at tangential velocity of 1500 m/min and removes a layer of the aluminum at a depth of mm. Whilst the workpiece moves at velocity of 30 m/min.
Surface grinding produces flat, angular, or contoured surfaces by feeding work in a horizontal plane beneath a rotating grinding wheel. Work is most often magnetically attached to the table, and may be ground by either a traversing or rotating movement of the table. Most surface grinding
Mount a wheel on the arbor shaft and secure with the washer amp; arbor nut (do not over tighten the nut on the arbor, it can induce wobble). Spin the wheel slowly by hand. Notice the amount of side to side wobble. If it looks minimal, turn on the grinder and observe the side to side wobble at high speed.
In the dressing of the grinding wheel, it is essential to effectively reduce the vibration, avoid leaving dressing scratches on the surface of the grinding wheel, colliding and damaging the dressing tool. This means that the balance of the grinding wheel is determined by the structural features of the grinding wheel

A combination of cotton laminate and aluminum oxide abrasive creates a smoother surface than other grinding wheels with similar grits. Grinding Bits Made of aluminum oxide, these bits are well suited for use on most metals and materials that are not heat sensitive.
