We use cylindraulic grinder to grind. The part is located between one end in internal diameter chamfer and centre hole made at the blocked end. The surface finishing our customer requested is between Ra 12 to 18 microinch without grinding defect (such as feed line, barber pole etc.). Currently we can only achieve surface finishing is Ra10-12 ...
Read OnWhat is mirror finish grinding? Mirror grinding is a grinding that the surface roughness of the workpiece is Ra< 0.01μm, and the light is like a mirror after grinding, so it can be clearly photographed. The flatness of the grinding surface is not greater than 3μm /1000mm. The surface machining of high precision and high added value parts ...
Read OnFinishing. Join Discussion. When using cutting wheels, hold the tool at a 90-degree angle, perpendicular to the workpiece. This enhances safety and helps improve wheel life and cut rate. Getting the best results in metal cutting, grinding, and finishing applications is a balance of numerous factors, including choosing the right abrasive product ...
Read OnIf the goal is to improve the current surface finish from 20 microinch Ra to 17 microinch Ra, then simply increasing the wheel speed and/or reducing the feed rate slightly might be sufficient. However, if a finer surface finish is required, then these five factors should be addressed. 1. Grinding Operational Parameters.
Read OnIt is a means of altering material surfaces through processes involving adding, removing, or reshaping the metal surface. Three (3) major characteristics can define the surface finish. They are surface roughness, waviness, and lay. The measure of the total space irregularities on the surface metal is known as Surface Roughness.

Read OnGrinding Factors If the wheel is fed into the work piece deeper than the exposed diamond length (i.e., if D c > D L), damage to either the grinding wheel or the work piece will result.In cases where D c = D L, a considerable amount of heat is going to be generated due to the rubbing that occurs between the work piece and the wheel bonding material.Coolant used …
Read OnFinish Grinding. In the finish grinding, clinker is mixed with gypsum and other minerals, such as blast furnace slag, according to the specifications of desired end products and are ground, or milled, to achieve required particle fineness. Finish grinding accounts for nearly 40% of the electricity use in cement production.
Read OnFine Grinding (flat parts – single or double-side) is the abrasive machining process for removing material using a bonded Superabrasive wheel at low speed with a liquid to keep the part cool. The fixed grain of a geometrically …

Read OnGrinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.
Read OnUse 40-, 60-, or 80-grain belts in a belt grinder to grind down the weld. Then use a coarse, medium, fine, or ultrafine conditioning belt to blend the surface.
