VMC-855T
VMC-855T Vertical Machining Center
T series high-speed vertical center with 36 m/min rapid feed, BT40 spindle and 24-tool magazine for complex workpiece processing.
Product Description
Application
The VMC-855T is the entry model of the T series vertical machining centers, built for fast feed rates and high spindle speeds on complex parts. Three-axis P-grade roller tracks, a box-shaped base and C3-grade pre-tensioned ball screws keep the accuracy stable. This model is part of our T Series Vertical Machining Center range; see the series page for the full model list.
