grinding and superfinishing processes

Precision Grinding Services | Western Machine Works | Oregon

Unlike regular precision grinding, superfinishing is done at lower speeds and produces a mirror-like finish. Also known as micro honing, superfinishing creates high geometric correctness (roundness, flatness, straightness) with an accuracy of 2 to 4 microns. ...

Superfinishing | SpringerLink

 · Superfinishing is a process in which a rotating workpiece is finished by a relatively soft stone with fine abrasive oscillating parallel to the workpiece surface. The stone typically oscillates at an amplitude of 1–4 mm and a frequency of 10–50 Hz, and it contacts the workpiece at light pressure, typically 0.1–0.2 MPa.

Surface Roughness Produced by Different Manufacturing Process

 · 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.

Optimized Grinding Processes

Optimized Grinding Processes. Cost savings up to 40%. Having the right abrasive is not enough. All components involved in the grinding process have to be perfectly adjusted as well. Cost savings of up to 40% have proven to be realistic. They can be achieved by reducing the amount of rejects, reducing cycle times and the amount of machine down ...

What Is Superfinishing in Metalworking?

 · Advantages of Superfinishing. There are several advantages of superfinishing, one of which is tighter tolerances. Most finishing processes involve the use of an abrasive to grind and remove material from a workpiece — and superfinishing is no exception. However, it uses abrasives with a finer grain than that of other finishing processes.

Honing, Lapping, and Superfinishing Services

 · Ideally, grinding and superfinishing operations should be synchronized to achieve the common goal of producing consistently good parts at the end of their interrelated processes. The grinder needs to take the workpiece to size within a prescribed semi-rough finish range and then leave it alone.

Isotropic Superfinishing Machines Manufacturer ...

By superfinishing, you can reduce the wear and tear of a product. Churning and grinding is a process done by humans for decades. It is the best way to refine an object. After a mass manufacturing process, the final surface is about 16 Ra (16 microinches). However, a superfinishing process will reduce this texture to as low as 2 Ra.

Supfina

Superfinishing is a chip removing machining process. But not one that is comparable to any other. In contrast to the classic lathe turning and grinding methods, there is full surface contact between the tool and the workpiece. This is precisely the feature that produces the unique characteristics of a perfectly machined surface.

Superfinishing Superfinishing is a variation of honing that is typically used on flat surfaces. The process is: Very light, controlled pressure, 10 to 40 psi Rapid (over 400 cycles/ min), short strokes-less than 1/4 in. Stroke paths controlled so that a single grit never traverses the same path twice Copious amounts of low-viscosity lubricant ...

Norton Microabrasives for Honing Superfinishing

Superfinishing is a high precision process to improve the final geometry and surface finish of the part, and to remove defects generated during grinding operations. Microfinishing is characterized by an oscillation of the stone, and the pressure of the abrasive on the rotating workpiece. ...

Precision Lapping | Precise Lapping | Lapping Process

Although lapping is an abrasive process, it differs from fine grinding or honing because it uses a loose style abrasive instead of bonded abrasives like grinding wheels. Precision Lapping for Harder Materials. The microfinishing lapping process allows for harder materials to be lapped to a more accurate tolerance than softer materials.

Our Superfinishing process takes over where grinding cannot achieve either the roundness/geometry or surface finish requirements. A unique feature of the process is its capability to produce both cylindrical and cross-hatch surface finishes, offering an ideal working compatibility for critical high pressure operating systems and specific seal ...

ATLANTIC :: Through-feed superfinishing

Through-feed superfinishing. In the through-feed finishing process two rotating drive rollers are used to both rotate and transport the rotationally symmetrical parts. This results in a (theoretically) infinite chain of workpieces, which are normally machined with finishing stones positioned above.
