Isotropic Superfinishing Machine

During the REM polishing process, active chemical always corrodes micro-pitting, leaving the surface with low surface roughness (0.02 Ra).

The process creates a uniform, non-directional surface while improving parts’ overall performance.

Also, the isotropic finishing process reduces parts’ friction and wears, increases parts’ life, and also increases corrosion resistance.

Isotropic Superfinishing Machine FAQ Guide

1. What is an Isotropic Superfinishing Machine?

An Isotropic Superfinishing Machine subjects workpieces to a unique process that leads to a non-directional low Ra surface.

It employs mass finishing equipment in conjunction with accelerated refinement chemistries that are non-hazardous and environmentally friendly.

By using high-density, non-abrasive media with isotropic superfinishing chemistry, the machine finishes your workpieces below 0.25 µm or nominally 10 µin.

2. What are the components of an Isotropic Superfinishing Machine?

Isotropic Superfinishing Machines are quite similar in form to the vibratory finishing machines.

Only that Isotropic Superfinishing Machines give parts a unique result.

Its components therefore include:

The Machine – This comprises the vibratory work tub or chamber, the motor, and various other interconnected parts that make the Superfinishing machine work.

 

The Compound-These are dry or wet substances added to the mass finishing machine.

It helps to reduce the corrosion of the machine and the media.

In addition, this chemical compound enhances the superfinishing process to meet the desired result.

 

The Media – This is the loose, non-abrasive substance that kicks at the workpiece, in the machine.

In other words, the constant rubbing of the substance against the workpieces aids in finishing parts’ surfaces to satisfaction.

The type of media introduced in an Isotropic Superfinishing Machine depends on the type of finish anticipated.

3. How does an Isotropic Superfinishing Machine work?

The Isotropic Superfinishing Machine deploys a chemically-accelerated vibratory mass finishing process.

It uses conventional vibratory finishing methodology and high-density, non-abrasive media to produce an isotropic super finished surface.

Notably, Isotropic Superfinishing Machines are capable of generating surface finishes with a 0.02 μm Ra.

Now, to achieve the required superfinishing, the workpieces are placed into the vibratory bowl or tub.

Such workpieces include automotive camshafts, valve springs, gears, bearings, rings/pinions, etc.

The chemically-accelerated refinement process consists of two steps that are sequentially conducted within the same machine.

Initial processing uses chemicals that react with workpieces’, producing a soft coat on the workpiece’s surface.

As the workpieces roll in the machine, the coating is wiped from them.

With this, we produce a good as new metal.

Once the underlying defects are removed and the improved micro-finish achieved, a mildly-alkaline, soap-like burnish chemical is released.

The chemical helps to neutralize and remove any residual coating remaining on the workpieces from the prior refinement step.

This finally yields a mirror-like final finish on the workpiece.

4. What functionalities does an Isotropic Superfinishing Machine offer?

Isotropic Superfinishing Machines help enhance and fine-tune the surface quality and outlook of workpieces.

Such surface refinement includes polishing, burnishing, deburring, and descaling.

rem process discription

Polishing/Burnishing:

This involves the processing of a workpiece to produce a luster finish on its surface.

To achieve this desired refinement, the appropriate media must be used

Deburring:

This is one of the most common usages of the isotropic superfinishing machine.

It involves the removal of edges and burrs on workpieces, left after machining. A common example of deburring is smoothening a sharp corner in a workpiece, into a rounded corner.

5. In what way is an Isotropic Superfinishing Machine different from other mass finishing machine processes?

When metal parts come into contact, contact stresses and friction occur which directly impact performance.

In time, this compromises the health and usability of such a component.

This is of particular concern with aerospace gearing applications, in which high contact stresses are present and high fatigue life is a requirement.

By improving surface finish with the superfinishing process, stress concentrations and wear can be significantly reduced.

To achieve optimal surface finishes on workpieces, machining or grinding of workpieces has historically been the chosen manufacturing process.

With these mass finishing manufacturing processes, resulting surface finishes typically hover around 16 RA, or 16 microinches.

But with the isotropic superfinishing process, surface finishes are reduced to as little as 2 RA.

This has a direct benefit on the life of the parts. In fact, such a huge surface finish reduction can increase the life of parts up to 300%.

This is because of the friction reduction caused by the product.

6. What type of workpieces are Isotropic Superfinishing Machines best for?

Isotropic Superfinishing Machines are widely noted for the special effects they have on workpieces.

These excellent functionalities make them a perfect and most preferred choice for superfinishing metals.

Suitable components for this treatment include motor shafts, gears, turbine vanes, blades for aeronautics, impellers for compressors, etc.

In addition are power transmissions, toothed joints, punches for dies, aerospace turbine blades, crankshafts, camshafts, valvetrain components, and many more.

7. What are the industrial applications of an Isotropic Superfinishing Machine?

As industrial machinery, Isotropic Superfinishing machines are special, as they are versatile.

They are used in a wide variety of special industries that lay emphasis on reduced roughness average (Ra).

Some of its industrial usage scenarios include:

Aerospace and Defense: Usually, metal smoothness and strength are usually a crucial requirement for aerospace and defense workpieces.

Their manufacturers thus use Isotropic Superfinishing Machines to optimize and make products conform to industry standards.

Some of the parts that benefit from this process include jet engine, turbine blades, and many more.

8. What are the necessary maintenance tips for an Isotropic Superfinishing Machine?

If one desires to make the most use out of the isotropic superfinishing machine, it’s important to take good care of it.

Some maintenance checks include:

Restore the media level:

The literal rule is to never allow the tumbling media level to drop, for whatever reason.

Some reduce it to save money or create room for mass finishing more workpieces.

Its consequence includes slow process time, machine or workpiece damage, non-qualitative finishing, etc.

Check the Vibratory Bowl or Tub:

The machine’s vibratory motion causes a lot of wear and tear in the superfinishing process.

Make sure that there are no holes in the tub or the chamber.

Don’t be tempted to put in too many workpieces:

Putting in too many workpieces at a time wouldn’t go down so well.

It could make workpieces impact on each other, damaging them.

Ensure to read and understand the manufacturer’s manual to know the machine’s capabilities.

9. Can vintage engine parts be Isotropically super-finished?

Yes. Matter of fact, vintage parts are usually manufactured from high-quality base metal types.

This will give them an outstanding “brand-new” look when isotropically super finished.

10. What is REM in Isotropic Superfinishing?

REM is an acronym for a specific isotropic finishing.

When an isotropic superfinishing machine is used appropriately, the results are the same.

11. How much material does an Isotropic Superfinishing Machine remove during processing?

Material loss during Isotropic Superfinishing is on the minimal side.

The loss is thus measured in Microns or one-millionth of an inch.

12. Are there side effects to workpieces that are super finished with an Isotropic Superfinishing Machine?

If the machine is used appropriately and correctly, a workpiece should suffer no detrimental effect(s).

13. What are the most appropriate media material for Isotropic Superfinishing Machines?

Isotropic Superfinishing Machines make use of several non-abrasive media that enhance metal workpieces’ surfaces.

Depending on the type of finishing needed, some popular media composition includes porcelain media, high-hensity media, etc.

Finishing shapes could also be of varying types including Cones, Pyramids, Cylinders, Sphere, Wedges, Tetrahedrons, and many more.

14. What are the actual technical merits derivable from an Isotropic Superfinishing Machine?

Lesser Friction

Isotropic Superfinishing Machines improve the structure of inserted metals to reduce their Roughness Average (Ra).

Such reduction varies substantially from machine to machine.

What’s most important, however, is that it makes the workpiece resistant to fatigue failure or easy wear-out.

This is because lesser friction translates to reduced wear & tear, high fuel efficiency, and lower heat generation.surface roughness of metal parts

Corrosion Resistance

An Isotropic Superfinishing Machine also helps minimize micro-notches, defects, and roughness, in a workpiece.

This gives a workpiece greater resistance against rust and other types & forms of metal corrosion.

Essentially, an isotropic-finished workpiece has a lesser probability of developing cracks and other imperfections.

Polished Finish

Not only is an isotropic-finished workpiece stronger, but it also gets a glistening look.

Isotropic Superfinishing Machines effectively remove visual defects by polishing the surface to give it a more appealing outlook.

15. Honing vs Lapping in Isotropic Superfinishing

Honing is a finishing process that produces an even surface on a metal workpiece, along a controlled path.

It is useful for improving the geometric form of a surface. Sometimes, it could be useful for surface texture improvements too.

Lapping, on the other hand, refers to a machining process in which two surfaces are rubbed together with an abrasive between them.

This is done to achieve some element of surface refinement and improvement while cutting down on process time.
