HIGH PRECISION GRINDING MACHINES LG HIGH PRECISION GRINDING MACHINES The LG cylindrical grinding machine has been developed for high precision component grinding, such as hydraulic components, automotive parts and cutting tools. The grinding machine’s natural granite base and the linear motor driven slides provide the high accuracy and thermal stability required for these high demanding applications. These specifications also allow the grinding of non-round components. The use of electric-spindle makes possible the combination of conventional and high speed grinding. This produces a maximum peripheral wheel speed of 140 m/s and covers the range necessary for grinding with conventional abrasive (60 m/s) or super abrasives (up to 140 m/s) with maximum torque. In addition the cylindrical high precision grinding machine is versatile and flexible with the direct driven B axis and the use of multiple wheels. Requirements of completely automated manufacturing processes are fulfilled with incorporation of customized automatic loading systems developed by DANOBAT, e.g. integrated gantry or robot solutions, guaranteeing minimum loading and unloading time (2-6 s. depending on applications).

Highlights • New grinding processes. • High productivity. • Short changeover times. • Complete part finished in one set up. Machine configuration • Machine main bed made of natural granite: thermal stability. • Moving table configuration. • X and Z axes driven by means of linear motors and controlled by linear scales: Repeatability and precision / Maintenance benefits • Grinding cutting speeds up to 140 m/s: Different CBN technologies: plunge, peel grinding, etc. • Built-in motors in workspindle, wheelspindle and “B”axis. • Customized user-friendly software. • Non-round and thread grinding capability. •...
