A special department of MasterTurbo is the in-house workshop, where our specialists perform turbo overhauls for customers every working day. The specialists have a lot of knowledge and experience when it comes to turbochargers, so together with the right tools they can get a turbo back up and running in most cases. In this blog, we discuss a few elements of the workshop that make a big difference in the operation and performance of a turbocharger.

The Bio-Circle machine

After taking the parts apart for overhaul, they are cleaned in our Bio-Circle machine to remove all grease and oil. This way of cleaning is not harmful to the environment and is a sustainable solution. The liquid used does not smell, contains no cold degreaser and has no fire hazard. In addition, the container contains a filter system where dirt and metal residues are removed from the cleaning agent, allowing the agent to be used again.

By choosing this sustainable solution, parts are cleaned in an environmentally conscious manner. After time, they are also completely rinsed, washed and dried to be completely free of particles and other debris. Then they go to the next step: the blast chambers.

The blast cabinets

Our blast cabinets come from Hengelo and are from the Leering company. These machines ensure that parts are completely clean and ready for further observation of the turbo problem and the rebuilding.

There are two machines in our workshop, the DI12 and the DP12. The DI12 contains a fine ceramic agent that is used as a kind of post-radiation to give the turbo a shiny effect. In addition, the DP12 is there for coarser pretreatment, where an aluminum oxide steel agent is used to get for example rust or paint off a part.

The machines are used manually and our specialists choose how hard the radiation is based on the amount of air added. Anyway, important and sensitive areas are protected or sealed to prevent damage or a change in size. Extra care must be taken in the case of certain materials, for example, aluminum. Cleaning in one spot for too long can cause damage in this case.

After using these blast cabinets, one more time the part is drilled and cleaned where necessary to remove the last remnants of dirt and dust. Then turbo parts are repaired, replaced and reassembled. Then they are ready to go to the balancing machine.

Balancing machine

One of the final steps in the overhaul process is balancing. Parts are also balanced at the manufacturer. This can be seen by a notch in the part, however, due to damage or overheating, parts can later become unbalanced. At MasterTurbo, this is therefore tested in precision at the end of the overhaul process to ensure a properly functioning turbo. Where necessary, the shaft is sharpened in order to properly adjust the turbo again.

Our balancing machines come from the company Cimat. Brands such as BorgWarner, Garrett and MAHLE are customers of the Polish company and the machines therefore stand for a high quality standard and technical innovation. We have two different machines.

The first is the CMT 48 Twin Big. This orange balancing machine consists of two workstations, where both passenger cars and heavier applications can be measured.

Our other machine is the Flowbench Turbo Test, which allows a large number of different turbos to be tested and multiple data measured, such as the performance of the turbo at minimum and maximum speed to ensure perfect operation in all conditions. Currently, our machine database contains as many as 2087 turbos!

At the end, reports are also printed out from the balancing machines, so the customer receives proof with the results and data. If the turbo is balanced and the correct values are achieved, it passes the test. Then the turbo is assembled, checked and prepared for shipment.
