Precision gear profile grinding is an essential requirement for gears which are components of high-speed gearboxes and critical aerospace applications. Er Makina manufactures precision gears that have optimal gear profile accuracy and high precision surface finish. We achieve the quality class 3 DIN 3961-3962 in spur and helical gears by using Höfler Rapid 800 LK and Höfler Viper 500. We are also able to grind worms with our grinding machine including worms with profile Zk, Zn and Za. Höfler Rapid 800 LK is capable of generating dressing programs that automatically dress the correct forms on wheels. Grinding operations are all performed in a separate clean and environmentally controlled room which allows us to hold tight tolerances​
