Grinding Techniques – a trusted partner to the foundry industry

The foundry industry has undergone a major transformation in recent years, yet despite the stagnation in steel and iron casting it is generating steady growth with more than 100 million tons.

Meanwhile, non-ferrous metals such as aluminium and magnesium alloys are increasingly coming into focus with foundries servicing an extremely diverse range of markets. Automotive manufacturers account for approximately 55% on the ferrous side and over 84% on the non-ferrous metal casting side with the second most important customer sector for foundries being general machine construction with around 40 different industry segments.

Innovative developments in cast lightweight components for electromobility and the requirement for improvements in thermomechanical properties demand constant growth and flexible adaption of the cutting and grinding processes.

Grinding Techniques, a company of the Tyrolit group, provide cutting and grinding solutions through seamless monitoring of the manufacturing process, from the raw material to the finished end product, this enables us to produce consistently high tool quality and at the same time increase the process stability with the growing degree of automation for cutting and grinding applications.

Cut-off grinding for removing risers and sprues
Cut-off grinding is the most frequently used process for removing risers and sprues. Owing to its high efficiency and productivity, cut-off grinding is used in many areas of cast iron and steel production.

Locally manufactured Superflex cut-off wheels impress with exceptional longevity and an attractive price-performance ratio. Our special production processes and comprehensive safety testing ensure maximum work safety and minimum noise levels during application.

When it comes to fettling, high demands are placed on the ergonomics and performance of hand-held grinding tools. All our Andor rough grinding wheels are manufactured to deliver the best high-performing results in every rough grinding application.

Grinding Techniques’ range of pendular grinding wheels ensure that fettling work can be performed with reduced exertion and higher stock removal rates. In this type of machining, one of the greatest challenges is vibration during application. Through intensive and ongoing development, Grinding Techniques are able to supply product into the market with significant reduced vibration levels enabling operators to work more efficiently. Working with an angle grinder is one of the most important processes in foundry sectors for machining all types of metals. When it comes to grinding large and heavy components, Grinding Techniques recommends the use of cup wheels, as they are exceptionally robust and durable. The composition of the cup wheels makes them suitable for large area machining of welding lines as well as fast material removal.

When working with cup wheels, it is particularly important to ensure that cup wheels are used only on angle grinders with diameters of 178mm. Smaller machines tend to rotate too fast, while larger ones rotate too slow. In addition, a special protection cover is required to ensure sufficient levels of working safety.

Straight grinders are always in high demand when precise results are required for difficult-to-access areas. Their versatile application options make them a popular tool.

Grinding Techniques’ vitrified and resin bonded Superflex mounted points offer you solutions for the highest quality requirements. The wide range of applications also requires ceramic points that strike a perfect balance in terms of chip performance, surface finish and longevity. Ceramic points are often used in foundries and mould making.

Apart from versatile mounted points, Grinding Techniques also stock a range of tungsten carbide burrs that are made from tried and tested, high-quality cemented carbide types on the most modern CNC grinding machines. Grinding Techniques’ Superflex tungsten carbide burrs are used on a wide range of handheld, pneumatic and electric machines as well as on industrial robots. Thanks to their versatility, they can be used on a variety of materials. To provide a solution at hand for the full spectrum of applications, Grinding Techniques, offers a wide selection of premium quality tungsten carbide burr shapes. The range easily meets the general demands of economic efficiency, high stock removal rates, simple handling and excellent longevity. Grinding Techniques has been the preferred precision grinding partner for decades. With constant innovation, development and research, we are able to offer a complete bespoke abrasive solution to suit your application

All Grinding Techniques’ products are manufactured and tested in accordance with International OSA and ISO Standards.
