CNC surface grinding is most proficient at producing tight tolerances and mirror finishes on flat, square, and parallel surfaces. Using form grinding (shaped wheels) or fixture grinding can achieve curved or angled geometry. A common application of CNC grinding is die sharpening, as it removes only the necessary material to produce a sharp edge.
A grinding wheel removes material in a similar way to a micro-milling cutter. In micro-milling, the cutting tools are identical in shape. The situation is quite different in grinding. The cutting tools in a grinding wheel are the grains, and material removal depends on their shape and position.
Resin bond diamond grinding wheel was divided into two parts, diamond working layer and aluminum matrix, working layer was combination by diamond powder and resin bond (resin powder and other mixed powder), and after fillers pressed under heat and pressure, solidify, then, firmly combined aluminum matrix, with a certain shape of diamond grinding tool.
Surface grinding is often used to achieve parallelism and squareness in cubic parts or to make the two ends of a metal rod perpendicular to the rod's outside diameter. As an alternative when turning or milling is simply not precise enough, surface grinding can achieve micron-level tolerances and surface finishes down to Ra 8 µin (0.20 µm).

Cylindrical Grinding is a process where you use a grinding wheel rotating in a horizontal axis to cut or grind a cylindrical work-piece mounted on a chuck or between centers rotating in an axis parallel to the grinding wheel axis, in the same plane. Abrasive particles on the grinding wheel do the cutting of material.

Plungecut grinding 7. Feed the wheel to the Work by hand and take a light cut, noting, that the wheel starts to cut approximately at the high point of the work. 8.
1A1 Resin bond grinding wheel is a kind of parallel grinding wheel. The grinding effect is very good, the working life is long, the self-sharpness is good, the calorific value during grinding is small, and it is not easy to block. It is very suitable for grinding hard alloys, ceramic materials and semiconductor materials.
Cross and parallel grinding modes are two typical general grinding modes for aspheric surface in vertical wheel spindle grinding system. In this paper, roughness, surface profile, form accuracy, and wheel wear of the ground aspheric surface utilizing the cross and parallel grinding methods are compared and investigated. Firstly, the maximum undeformed …
1:40 or 50 (depending upon the grinding wheel) and is used for grinding the following materials. oCast iron or hardened steel oSoft steel oConnected carbide tools (using silicon wheel) In India we use IOC Servocut oils as cutting fluid. There is a special grade oil manufactured by IOC for grinding alone. It is called Servocut - clear.
the wheel on the part tends to deflect the quill & wheel away from the surface of the bore. So the surface of the wheel is never entirely parallel to the surface it is grinding. This slight deviation from parallel may cause unacceptable taper in the bore where the quill/wheel is …
Fine grinding GPK wheels are used in the production of parts requiring perfect parallelism and high surface quality. The wheels, which utilize premium diamond or cBN grain require low pressures and feature long sharpening intervals allowing for long wheel life. Fine Grinding GPK wheels work by grinding parts while they are
To improve the performance of conventional cylindrical plunge grinding processes, this paper introduces parallel grinding which employs an extra grinding wheel opposite to the original one, simultaneously cutting workpiece. Depending on the relative location of the two wheels, the cutting areas are divided into non-overlapped and overlapped zones. In …
Double-Disc Grinding is a highly efficient grinding method that reduces pre-machining costs up to 50% and provides dimensional tolerances, parallelism, and flatness to ±.0002". Double-Disc Grinding uses two opposing abrasive wheels to simultaneously grind two sides of a blank.
The high material removal rates result of an angled grinding wheel surface by which the total radial infeed a e is reduced to an effective infeed a e,eff. Such grinding wheels feature a roughing zone with an angle of α = 12° and a cylindrical finishing zone parallel to the workpiece contour.
Mostly we use are silicon carbide(GC) dressing wheel while diameter is 205mm, grit 180#. Moresuperhard supply full series vitrified diamond and CBN grinding wheels for the top and bottom grinding. This flat grinding can achieve very high precision in height and parallelism, so it best choice for your PCD,PCBN and other materials cutting inserts.

Wheel truing is defined as act of restoring the cutting face of a grinding wheel by removing the abrasive material from the cutting face and sides of the wheel, so that it will run true with respect to the axis of rotation and produce perfect round or flat work. It also includes the altering of the cutting face shape to produce special contours.
Centreless grinding is an OD grinding operation where the work piece seeks its own axis of rotation between the grinding wheel and a regulating wheel. The key components in the process are the grinding wheel, the work rest blade (used to support the work) and the regulating or "feed" wheel (the drive mechanism for the work piece).

The grinding wheel, rotating in the same direction as the workpiece, grinds when contact is made: this allows for a smoother operation and mitigates the risk of jamming. ... When both sides of the workpiece are being worked on at the same time, higher accuracy and better parallelism is achieved and stress on the part is reduced, making it ...
In this type of grinding operation two grinding wheels are fitted parallel with a little 5-10 degree angle, this angle is provided to get a longitudinal motion of the workpiece. A cylindrical rod is entered between the two grinding wheel due to the tilted angle the workpiece is automatically pass through the wheels, and we got a smooth surface.
between tooth flank and grinding wheel. Due to the plunge movement of the grinding wheel in the axis direction, the grit path runs in parallel to the tooth base and the surface structure runs in the tooth width direction. Grinding grooves running in parallel to the tooth base emerge. The grinding direction is from the ring gear toe at the
