  • Frequent problems during grinding grindaix GmbH

    The most frequent problems during grinding include: Overly high infeed. When grinding parts (workpieces), the process generates a great deal of heat, which is ideally led away with the chips and the coolant lubricant. However, it is impossible to avoid some of the heat entering the part. As long as the heat input into the part is not too great, this poses no problems to the production process.
