Machining small bores into small parts presents production challenges, due to the difficulty of ensuring the stability of both tool and component. Accuracy and tool life are dependent on the process having more finesse than is the case for larger bores in larger components. As a result, the MPM has been designed with separate drives to each of its spindles, offering the ability to program the speed of the individual tools. In addition, torque feedback for each spindle monitors tool performance.
The diamond bore finishing tools used on the MPM are specified individually for the material and component being machined.Engis MPM offers micro-bore finishing on small parts
Engis’ Micro Precision Machine (MPM) single-pass bore finisher is for small components with bore sizes from 1.4 to 10 mm in diameter. Using Engis diamond-plated bore finishing tools, the MPM can achieve bore geometries to within 0.5 micron in standard and semi-blind bores.
