* NEW DNM SERIES:

Building on the history of the well proven and successful DNM and DNM II series, the new version DNM series boasts even greater reliabitily and performance. In addition, the new series includes grease lubrication to the roller  guideways for more environmental friendliness. The design concepts of the DNM 4500, DNM 5700 and DNM 6700 are high speed, high rigidity and suitability for universal applications. Standard features are the largest machining space in its class, direct coupled spindle, roller guideways and thermal error compensation to provide optimum precision.

* FEATURE:

1. A highly versatile vertical machining center offering the largest machining space in its class: While requiring the same installation floor space as the previous model, the new DNM series provides a larger table with increased Y axis travel and maximum table load.

2. Standard Direct -Coupled Spindle for Higher Productivity:

  • The direct coupled spindle reduces vibration and noise, thereby improving the machines performance and environmental-friendliness compared to belt drive type.
  • Higher productivity is achieved by reducing tool change time and improving all axes feed system acc/dec times.

3. An environmental-friendly machine designed for stable and easy operation:

  • Thermal error compensation function fitted as standard optimizes machine accuracy by reducing the effects of heat build-up during extended periods of operation.
  • The EOP funtion can be checked in the pop-up window on the NC main screen for convenient machine operation.
  • Grease lubrication for axis  roller guideways is a standard feature and contamination of the operator’s environment.
