Optimizing grinding and dressing with ‘dressing speed ratio’ parameter

To achieve the quality and productivity requirements for most precision grinding operations, it is necessary that the grinding wheel is trued and dressed prior to grinding and periodically during the grinding operation. The truing process is initially performed to correct for any wheel runout, create the required profile on the wheel and condition the grinding […]

Grinding with a taper

Dear Doc: We cylindrical-traverse-grind long steel parts. We must follow a specification from 1970 that stipulates “traverse maximum one-eighth of the wheel width per workpiece revolution,” which is contrary to what you preach regarding using almost the entire wheel width during rough grinding. Is there something we can do? Our cycle times are eight to […]

Up-grinding vs. down-grinding

Dear Doc: I took your course, and you said that in 99% of grinding operations there’s no significant difference between up-grinding and down-grinding. But I think that our case falls in that 1%. Due to centrifugal expansion, we have to cylindrical-plunge-grind our workpiece at the speed it runs in its actual application, which is 3,000 […]

Learn the ins and outs of centerless grinding

Anyone who earns a living at a machine shop probably has heard about centerless grinding, but it is an obscure process often only familiar in name. The three basic types of centerless grinding are through-feed, in-feed and end-feed. In each case, the fundamental configuration of a machine is identical. The three primary components of a […]

In-feed centerless grinding

Abrasive treatment where the workpiece is first placed in its working position, and a grinding wheel is then applied radially against the workpiece. Typically used to create a complex surface. The process A cylindrical workpiece, usually of non-axial symmetry, is held for processing by a grinding wheel which is fed in towards workpiece. The workpiece […]

Grinding Machine: Definition, Types, Parts, Working & Operations

In the manufacturing process grinding operation is also an important operation to make a finished product, so let’s start the topic. Grinding Machine Definition: A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the material. It is a process of metal cutting by using a […]

Cylindrical Grinding Machine: Types, Process & Working Principle

Cylindrical Grinding Machine: Types, Process & Working Principle :- Cylindrical grinders are employed to slice or cut very precise and subtle finishes on materials such as aluminum, carbide, steel or other metals. They are especially used to work on cylindrical surfaces, rods or other cylindrical work pieces. The cylinder lays in the middle of tow […]

Grinding Techniques – Your premium metal fabrication partner

Since the beginning of time, man found value in utilising various materials to produce products related to self-sustainability. These materials evolved over time as technology and expertise increased, right from the humble beginnings of the copper age to the current highly sophisticated alloy age. As technology and manufacturing methods advanced, iron and iron tools became […]

Helping Your Parts Shine On

Avoiding the drudgery of deburring and finishing operations The deburring and finishing of machined and fabricated parts is a necessary but often disregarded step in the manufacturing process. As a result, some shops still approach this task much as they did in the previous century, relying on manual deburring and polishing methods over more modern, […]

Surface grinding large plates

Dear Doc: We surface-grind large (0.6 m × 1.2 m, or 2’×4′) tungsten-carbide plates, removing around 1 mm (0.04″) per side with a 180-mesh, resin-bonded diamond wheel. We don’t true the wheel but just let it self-dress. It’s an ugly process. The machine moans, cycle times are long, and surface finishes are bad. What can […]
