Grinding techniques – moving the automotive industry forward

Global warming is playing a major role in climate change, wreaking havoc in parts of the world with out-of-control veld fires, severe floods and droughts. The main contributing factor is the high level of carbon dioxide released into the atmosphere by gas emissions from internal combustion engines. Renewed focus on climate change and tougher policies are changing the way motor vehicles will be produced in the future. Manufacturers are reducing engine size but increasing engine capacity by adding turbochargers, which places great emphasis on the quality and surface finish requirements of engine components. Reducing the weight of the alloys and materials chosen poses a great challenge in the machining of these components.

Grinding Techniques, a Tyrolit company, has the local experience and expertise in providing cost-effective grinding solutions to meet the needs of the automotive components and automotive remanufacturing market of Original Equipment Manufacturers (OEMs), by especially the grinding of crankshafts. Our local research and development (R&D) center allows us to provide the best possible product specifications while achieving low machining costs per unit.

When looking at the entire grinding process, business development specialists are able to offer support on all technical issues considering the grinding solution, machine, grinding wheel and favorite dressing tool. One of the main challenges encountered in grinding crankshafts is the “out of balance” of the wheels, especially due to the lack of training on safety checks, assembly and balancing procedures, as well as on crankshaft wheels having larger outer diameters and smaller widths, which accentuates any “imbalance” condition. With proper operator training, this problem can be eliminated. Grinding Techniques can provide the necessary training.

With our local range of ANDOR grinding wheels, we can produce grinding wheels up to 1015 mm in diameter.

The shift to light alloys and higher surface finish requirements on engine components has led to a dynamic evolution in the production of conventional and super abrasive grinding wheels. By utilizing the latest in high quality aluminum oxide technology, the challenges of CBN grit and bonding systems experienced with issues related to ground parts and insufficient tolerances, are minimized and further utilized in the automotive remanufacturing market, earthmoving equipment and armored vehicles.

Specific to the automotive reconditioning market, we have products available for crankshaft and camshaft grinding, polishing, valve seat and rod end grinding as well as the brake and engine industry. clutch, among others. We also use the latest CNC machining which allows us to produce wheels for the gear industry with a range of modules, pressure angles and starts required for continuous generation and grinding of gear profiles. By adding sintered aluminum oxide to various products, we are able to reduce the overall production cost per unit, while achieving cool cutting and good form retention on the wheel.

A partnership with Grinding Techniques offering bespoke products with competitive lead times and custom grinding solutions will go a long way in moving the automotive industry forward.
