Lathe – parting off (and grooving) Parting is the process whereby a part that has been made, or is wanted for another operation, on the end of a bar is cut off from the rest of the bar, which is, usually, being held in the chuck. This is a very common way of holding a component whilst it is being made and so parting is a very common operation.
In parting and grooving, process security and productivity are two important aspects. With the correct setup and choice of tools, there are many difficulties that can be avoided when parting-off. Difficulties such as pips and burrs, tool breakage, chip jamming, poor surface finish on components with complex grooves, incorrect coolant pressure ...
If a machinist places an important feature on the wrong side of the parting line, it could lead to serious issues with the whole injection molding process. This article will fully explain the formation process of parting lines, the different types of parting line in injection molding and how to consider them while designing your part.
During the grinding process the workpiece material undergoes localized deformation, with this deformed material being displaced later. The localized deformation between the workpiece and the abrasive is called plowing. The plowed material slides — more on that later — on the grinding wheel surface prior to leaving the grind zone.
The wet grinding process occurs when a product is transformed from solid to liquid, regardless of its viscosity: paints, inks, enamels, nail varnish, among others. In this process, agglomerates that were not separated in the dispersion phase (due to the electro-physical bonding of some components) are broken by applying extra energy.. This wet grinding process uses beads or …
Thai Kin has a variety of processes to machine those features. Undesirable by-products of the cast like parting line and burr are removed via grinding process. Surfactants from the cast that are not desirable are then buffed away to a finish matching the final product prior to plating. Liquid and Powder Coating.
Parting and grooving inserts are inserts for cylinder parting and grooving, including to the outer circular, the inner hole groove, the cutter withdrawal groove, and the end face groove. The groove shape includes the narrow, wide, and forming groove. The process features of these inserts are as follows:

Grinding uses fixed abrasives—the abrasive particles are bonded to the paper or platen—for fast stock removal. Polishing uses free abrasives on a cloth; that is, the abrasive particles are suspended in a lubricant and can roll or slide across the cloth and specimen. A book edited by Marinescu et
The process involves the part being supported on a workpiece rest blade that sits between two rotating cylinders: A regulating wheel, which controls the part's rotational speed and feed rate (for in-feed grinding) or linear travel (for through-feed grinding) A larger abrasive grinding wheel
Grinding flat or plane surfaces is known as surfaces grinding. Two general types of ... The manufacture of these wheels is a precise and tightly controlled process, due not only to the inherent safety risks of a spinning disc, but also the composition and ... Cut off or parting wheels are self-sharpening wheels that are thin in width and often
Removing the burr will probably improve the situation. This effect might also indicate that a lighter touch should be used in the grinding process. Sharpening symmetrical-bevel parting tools. This includes the rectangular and diamond parting tools as well as the much wider beading/parting tool.
Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams.
Notching is a sheet metal cutting process that involves the removal of material from a work piece, starting at the edge and cutting inward. The objective of notching is to create a sheet metal part with a desired profile. Notching is often performed as a progressive process, each operation removing another piece to make the correct contour.
Even so, this little tool is tempting, because grinding a parting tool from a tool blank is a pain - since so much metal must be ground away - and parting tools get dull and break easily. This tool, and similar larger ones, use pre-formed cutting tools. If you break off …
This results in a much more stable, silent and vibration-free cutting process that gives better surface finish and allows higher feed rates and longer tool overhang. CoroCut® QD for Y-axis parting is the first choice for parting off in turning centres and multi-task machines with Y-axis.
You can process that part later to add to ground venison. Now, you have St. Louis style ribs. Use the bone saw to remove the remainder of the ribs. An extra set of hands comes in very handy on this step. A pro tip is to use your knife to cut through the muscle to the bone before starting to cut with the saw. ... Tricks for Grinding Venison.
Surface Roughness Produced by Different Manufacturing Process. Knowing what manufacturing process can produce surface finishes that desired on a surface can be an added advantage while making the designs. Here is a table showing maximum and minimum Ra values can produced on each production methods. Elect. Discharge Machining. Perm. Mold Casting.
The grinding ball is a grinding medium used in ball mill and material used in grinding mills, widely used in metallurgical mines, cement building materials, thermal power generation, flue gas desulfurization, magnetic materials, chemical industry, coal water slurry, pellet, slag, ultrafine powder, fly ash, calcium carbonate, quartz sand, and other industries ball mill.

Grinding process control balances these three interactions to achieve the desired parameters. These interactions feed into three major commercial grinding processes: rough grinding, precision grinding and ultra-precision grinding. Rough grinding maximizes the metal removed at the cost of surface finish.
Parting A parting tool is deeper and narrower than a turning tool. It is designed for making narrow grooves and for cutting off parts. When a parting tool is installed, ensure that it hangs over the tool holder enough that the the holder will clear the workpiece (but no more than that).
This applies to the part in process. Remember that as you pull the tool out to go incrementally deeper in a large diameter the tool also goes uphill and above centre. Try these suggestions and you should be parting like it's nothing. **With the 1/16 wide tool don't try grinding a side angle on it so the cutoff nub stays with the stock in the lathe.
