Different Types Of Connecting Rods Supported For Polishing

Titanium connecting rods are well known for its strength and performance. The light weight and durable features of the titanium metal makes it the best choice for making connecting rods. They are used in engines of many sports vehicles.

The vibratory tumbler finishing machine or the tub vibratory finisher machine can be used to finish the titanium connecting rods. Use the right type of tumbling media to get the best results.

The cast steel connecting rods will have less strength when compared to the stainless steel connecting rods. It is due to the low carbon content in the cast steel connecting rods. The low manufacturing cost of cast steel makes it attractive to many customers.

The vibratory tumbler finishing machine along with a suitable vibratory tumbling media can be used to deburr and finish cast steel connecting rods. You can get high quality finish on cast steel connecting rods with the help of the right tumbling media.

Different types of metal or metal alloys can be used in the machined connecting rods. They undergo a lot of stress inside the engine. So, proper finishing is essential to ensure that they don’t break down during the stress. Proper deburring and surface smoothening is required for the machined parts as it will have lots of imperfections.

The high energy centrifugal barrel finishing machine or the centrifugal barrel finishing machine can be used to polish the machined connecting rods. You can also make use of the standard vibratory tumbler finishing machine to polish the parts. Make sure to use the right media that match with the material type.

The forged connecting rods are stronger than the cast steel one. It is due to the strong interlinking bonds inside the connecting rods. The surface of forged connecting rods will not be smooth after the manufacturing process. So, deburring and polishing is essential to get the final finished part

A vibratory polishing machine or a centrifugal disc finishing machine can be used for deburring and polishing forged connecting rods. You can use the matching tumbling media of right shape and size to get the desired finish

There are many benefits of using aluminum connecting rods over the standard cast steel connecting rods. The strength of aluminum connecting rods is less than the forged ones. But, they provide more shock absorbing capabilities. It will help to remove the excess force on the crankshaft.

The centrifugal machine or the vibratory tumbler machine can be used to clean and polish aluminum connecting rods. Use plastic tumbling media for finishing aluminum connecting parts as they exert vey less pressure on the parts for polishing.

The connecting rods of boosted engines are known to have high fatigue life. They are made up of different types of metal or metal alloys.

So, polishing is essential to remove all the weak spots from the connecting rod. We recommend to use the vibratory tumbler finishing machine for polishing and cleaning the boosted engine connecting rods.

Connecting Rods Polishing Media

Different types of metals and metal alloys are used to manufacture connecting rods. So, different types of media need to be selected for each of these material types. Inovatec machinery manufactures different varieties of mass finishing media which can be used for cleaning and finishing connecting rods. The ceramic media is useful for finishing connecting rods made of cast iron.

The porcelain media is useful for polishing connecting rods. These media will not have any abrasive content in them. The plastic tumbling media can be used for surface preparation of connecting rods. Other organic media alike corn cob granules and walnut grit can also be used to polish connecting rods.
