REM Polishing Machine

The role of the chemicals during the REM polishing is to corrode the material so the surface becomes a low roughness one. Approximately 0.002 Ra. As a result, the surface of the part becomes smooth with enhanced parts performance.

The REM finishing also reduces the probability of wear and tear which prolongs the parts’ life and improves resistance against corrosion.

One of the perks of the REM polishing is that it can be done with vibratory tumblers or centrifugal finishers. Whether it’s a bowl or a tub, it doesn’t matter.

REM Polishing Machine FAQ Guide

1. What is a REM Polishing Machine?

An isotropic rem polishing machine is a mass finishing machine that uses a unique process to finish a workpiece. The final surface becomes a non-directional low roughness one. Along with the regular vibratory or centrifugal process, it uses active chemicals to accelerate the process.

It’s crucial to use non-abrasive and high-density media in order to get the best results from a REM polishing process. The machine is capable to work on parts below 0.25 µm or nominally 10 µin.

 

2. What are the parts found in an isotropic superfinishing machine?

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

If you think that an isotropic superfinishing machine is something from the future, you’d be wrong. It looks very similar to your regular vibratory finishing machines. In addition, there would be a dosing pump that provides the active chemical to corrode the parts.

The components of an isotropic finishing machine are:

The Machine:

It’s the tub or bowl where the parts are going to be polished. There is a motor that causes the vibration and some other interconnected intricate parts to let the machine do its job.

The Compound:

In most cases, there is a compound added to the mix to help reduce the corrosion of the parts, the machine surface and the media. The chemical is also a compound that accelerates the process and balances the scale.

The Media:

The media is probably the most important component of an isotropic superfinishing machine. The media is a substance of non-abrasive property that rubs against the workpieces to smoothen the surface.

The types of media will be determined depending on your goals. There are a plethora of media that works with different materials.

3. How does the REM polishing machine work?

The REM polishing is a vibratory finishing process but infused with active chemicals. So, you can call it a vibratory finishing process. It uses high-density and non-abrasive media along with the chemical to create a super-even surface on the workpieces.

The isotropic superfinishing process can finish a wide variety of parts. It can be crankshafts, camshafts, medical equipment, valve springs, bearings, aerospace parts, dental parts and basically everything else.

The parts are put on the bowl or the tub of the vibratory finishing machine. It can be a centrifugal disc finishing machine as well. After the parts, the media and the compound are added. It’s a two-step process that is done in the same machine.

First, the parts are chemically coated for a soft conversion coating. Once the parts start rotating or vibrating inside the machine, the coating is ground and bare metal is exposed. Once all of the parts go through the same process, the next phase starts.

In the next phase, an alkaline burnishing compound is released inside the machine. This soap-like chemical helps remove the residue or any other particles from the surface of the parts. After the phases are completely done, you’ll be left with a batch of shiny and polished parts.

4. What can I do with an isotropic superfinishing machine?

The characteristic that differentiates isotropic superfinishing machines is the ability to create the superfine surface finish. Vibratory and centrifugal processes do a decent job but when precision becomes key, there is no alternative to a REM polishing machine.

These machines can do a variety of things to the surface of the parts including polishing, deburring, burnishing, etc. Let’s take a look at them:

Polishing/Burnishing:

One of the primary goals of the REM polishing process is to create an everlasting luster on the surface of the parts. If you manage to use the right media in the right context, you’ll be amazed by the results.

Deburring:

Deburring is a much-required process no matter what the parts are. And isotropic superfinishing machines are widely used to achieve the necessary deburring results. The machine removes sharp edges, smoothens the corners and make the parts smoother before the polishing.

5. Why is isotropic superfinishing machine different from other mass finishing machines?

One important characteristic of the metal is that when two metal pieces come in contact with each other, they create friction, stress and heat. These characteristics are directly related to the performance of the parts.

Over time, the stress and friction weaken the internal bonding of the metal molecules. It’s a massive issue when it comes to delicate parts like aerospace parts, automotive parts or industrial equipment. These parts require high resistance against fatigue to work efficiently.

All these stated issues can be solved with the help of REM polishing. The stress is reduced from the parts and the wear resistance goes higher. It’s also essential to choose machined or ground workpieces for the applications.

With the mass finishing processes conventionally in place, it’s possible to finish surfaces down to 16 microinches. But with the isotropic superfinishing process, it’s possible to go down to 2 RA. It’s a direct impact on the lifespan of the parts.

As a result of the REM polishing, the life of the parts can increase up to a whopping 300%. It’s all thanks to the reduction in friction and enhanced rolling contact.

 

6. What type of workpieces is perfect for the isotropic superfinishing process?

Isotropic superfinishing machines or REM polishing machines are held very high up in the mass finishing industry for their ability to work on a wide variety of products. The machine is packed with modern features that make them the best choice for any mass finishing job.

You can polish motor parts like shafts, crankshafts, gears, transmission parts. You can also process delicate parts like aerospace blades, propellers of boats and compressors. It doesn’t matter what is the size or shape of your parts, you can do REM polishing on them.

 

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

Isotropic superfinishing machines are very versatile. They can reduce the roughness of any metal surface to a significant level. Let’s look at some of the industrial uses of the machine.

Defense and Aerospace:

The defense equipment is a very crucial investment for any country. So, it’s mandatory that the quality of the equipment is top of the line. So, isotropic superfinishing is widely used in defense equipment industry to ensure maximum precision.

The same goes for the aerospace industry. One mistake in the finishing can prove to be fatal. So, the isotropic superfinishing machines are widely used in the aerospace industry as well. These parts include jet engine parts, engine propeller, turbines, etc.

Automotive Industry:

Another huge industry where REM polishing machines are used is the automotive industry. Automotive parts go under tremendous pressure during each cycle. So, it’s crucial to increase the fatigue resistance of those parts.

Parts like pistons, connecting rods, cylinder heads, gears, transmissions, engine heads, etc. are most prone to damage if the polishing isn’t done properly.

Motorsport is a big part of the automotive industry. Parts used in motorsport are very likely to breakdown under heavy load. So, those parts are finished using the REM polishing machines. Parts like hydraulics and pneumatics go in this category.

8. Can I get some tips to maintain the isotropic superfinishing machine?

Whatever equipment you use, it’s essential to take good care of it. Proper maintenance ensures longer life and higher efficiency. Let’s look at some maintenance ideas for your isotropic superfinishing machine.

Accurate media level:

Don’t ever let your machine run low on media. You might think that you’ll save some money but you’ll be ruining the machine in the long run. You’ll slow the processing time, the workpieces will get damaged and the inside of the machine will also get damaged.

 

The health of the vibratory tub or bowl:

All the actions take place in the bowl or the tub of your machine. So, it’s important to take good care of the bowl. Make sure that you take a look at the bowl frequently. Look for uneven wear, holes or anything that doesn’t fit.

 

Don’t rush:

Putting more workpieces than your machine can take is a fatal mistake. You run the risk of damaging the workpieces themselves, damaging the machine and prematurely wearing the media down.

Go through the manual properly and know the limitations of the machine.

 

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

Yes, it’s possible to restore vintage or old engine parts. In most cases, old parts are made from high-quality metal. So, when you isotropically finish them, they become somewhat new parts.

 

10. What is REM in Isotropic Superfinishing?

REM and isotropic finishing are basically the same thing. Isotropic finishing refers to a wide array of applications while REM narrows the list. When you use the machine properly, you won’t notice a difference in results.

 

11. How much material removal am I looking at while using the REM finishing machine?

The material you lose from your parts surfaces is very negligible. It’s not possible to say exactly how much but it’s measured in microns which is one-millionth of an inch. It’s insane how precisely an isotropic superfinishing machine works.

 

12. What are the effects on the parts finished in a REM polishing machine?

If the process is done correctly and with the correct media, there will be no negative effect on the parts.

 

13. What media should I use with these machines?

As long as the media is non-abrasive, you can use any media you want. But unfortunately, it’s not that simple. Each operation requires different media. Inovatec has all kinds of media available for you to buy. You can ask for our assistance as well if you’re not sure which media to use.

Some of the most popular media for REM polishing are porcelain and plastic. You can get it in high-density, cones, pyramids, spheres, cylinders, etc. shapes.
