Unless the spindle is thrashed, I'll betcha you can grind a 3" x 3" x 1" block parallel and flat within 0.0005" even if it's pretty worn. For a lot of guys and a lot of jobs, that's plenty good enough. I have the opportunity to acquire a Brown and Sharpe 510 Surface grinder. it is a manual machine as many should know, but I have never owned a ...
Surface grinding . Surface grinding uses a rotating abrasive wheel to remove material, creating a flat surface. The tolerances that are normally achieved with grinding are ±2 × 10 −4 inches (5.1 μm) for grinding a flat material and ±3 × 10 −4 inches (7.6 μm) for a parallel surface.
According to DIN 8589-11, surface grinding is classified as a face-peripheral-longitudinal grinding process, which is widely used in industrial applications to produce flat surfaces. According to the position of the grinding wheel in relation to the surface to be processed, this process is divided into: Face-peripheral-longitudinal grinding
1. Horizontal Spindle Surface Grinder (with Reciprocating Table) Your Horizontal Spindle Surface Grinding Machine consists of a base on which a bed made of high tensile strength cast iron (for better vibration damping and …
Bonus footage! Title says it all, though this is specifically about grinding wheel wear.FYI, my go-to general purpose wheel is a Norton 5SG.
Tool and cutter grinder; 1. Cylindrical Grinder. The surface which has been made plain by shaper or plainer are grinded with this grinder. The cylindrical surface is grinded with a machine in which grinding wheel is fitted on the shaft of a free electric motor.

Above: Grinding wheels with different grain sizes. The grain size in your grinding wheel is classified as coarse 8-30, medium 30-60, fine 70-180 and very fine 200-600.The material removal rate will be more for your grinding …
....peripheral surface grinding operations on medium size machines with drive motors in the above mentioned 5- to 12-hp range, reflect common practices and are intended for general information only: (1) The work speed results from and is equal to the speed of the reciprocating table movement.
1. Horizontal Spindle Surface Grinder (with Reciprocating Table) Your Horizontal Spindle Surface Grinding Machine consists of a base on which a bed made of high tensile strength cast iron (for better vibration damping and shock absorption) is assembled.
Typically surface grinders can grind within .0001 - .0002 but not all surface grinders are created equal. The less expensive models may not hold up to tool room accuracies but could be used effectively to sharpen punches, dies or do repair shop work.
Above: Grinding wheels with different grain sizes. The grain size in your grinding wheel is classified as coarse 8-30, medium 30-60, fine 70-180 and very fine 200-600.The material removal rate will be more for your grinding wheel with coarse abrasives and less for a wheel with fine abrasives; also grinding wheels with fine or very fine abrasives gives a better finish …
Machining surface finish chart, comparator, method, degree, Ra, Rz, RMS As for machining to iron and steel castings, the surface finish smooth degree is also an important requirement. The following is the conversion chart is from dandong foundry, for Ra (um), Ra (micro inch), Rz (um), RMS and finish degree in China and USA, including the related finish methods.
Advent of advanced grinding machines and grinding wheels has elevated the status of grinding to abrasive machining where high accuracy and surface finish as well as high material removal rate can be achieved even on an unhardened material. The bulk grinding wheel – workpiece interaction as given in Figure 2 can be divided into the following

Surface grinding. Surface grinding uses a rotating abrasive wheel to remove material, creating a flat surface. The tolerances that are normally achieved with grinding are ±2 × 10 −4 inches (5.1 μm) for grinding a flat material and ±3 × 10 −4 inches (7.6 μm) for a parallel surface.
Surface grinding services can also be used on rods, although not to make the outside diameter of a rod round; for that task, OD grinding (also known as cylindrical grinding) is used. However, surface grinding can make the two ends of a rod perfectly perpendicular to the outside diameter. Here, V-blocks are used to position rods for grinding.
Figure 1. Chevalier Surface Grinder. Dressing the Wheel. 1. Place the diamond wheel dresser onto the bed. 2. Keep the diamond dresser ¼ of an inch to the left of the center of the wheel. 3. Lock the dresser onto the bed by turning the magnetic chuck on. 4. Turn on the machine power by turning the switch to the "ON" position.
1.Factors related to grinding wheel affecting the surface roughness of grinding Mainly the grain size, hardness and the dressing of the grinding wheel The finer the grain size of the grinding wheel, the more abrasive grains per unit area of the grinding wheel, the finer the scratch on the grinding surface, and the smaller the surface roughness value.
Modern rotary surface grinders like those from DCM Tech can reliably achieve tighter dimensional tolerances, flatness, parallelism, and surface finish in much less time. DCM Tech With regard to production efficiency, the advanced rotary surface grinders are also much faster than reciprocating grinders because the units can get much closer to the required …
