Simultaneous 5-axis vertical machining center with roller-gear trunnion table.
Featuring a rigid tilting/rotating trunnion table, the MEGA 20VT allows job shops to process complex multi-sided parts in a single setup (done-in-one). Ideal for medical implants and compact aerospace fittings.
Provides absolute rigidity, dampens vibration during heavy metal removal, and ensures lifelong structural stability.
Proprietary dynamic error correction checks thermal expansion in real-time with ±0.1 µm resolution. No warmup cycles needed.
Dual contact spindle with hybrid ceramic bearings reduces spindle vibration, heat growth, and yields superior surface finishes.

DYPEC® (Dynamic Y-axis Predictive Error Compensation) is Micro Dynamics' proprietary real-time thermal compensation system. Embedded sensors monitor structural temperature gradients across the casting, spindle housing, and ballscrews, feeding corrections to the CNC controller every microsecond.
Thermal drift is eliminated before it affects part accuracy. No warmup cycles needed at shift start, and consistent micron-level tolerance is maintained across 24/7 production runs.
Learn About DYPEC®
Every Micro Dynamics machine is built on an FC300-grade Meehanite® casting—a premium class of gray iron with controlled graphite microstructure. The casting undergoes FEA-optimized ribbing to create a high-rigidity base that absorbs cutting vibration.
Superior vibration damping for finer surface finishes, thermal stability to prevent geometric drift, and long-term structural integrity throughout decades of heavy use.
Explore Casting Engineering
The Micro Dynamics HMI runs on a Windows-embedded 15" touchscreen console powered by Mitsubishi M830VW CNC control. Combines conversational programming, Renishaw probing, tool data management, and real-time diagnostics.
With a 5,400-block look-ahead buffer and EtherNet/IP networked I/O, the controller executes complex multi-axis toolpaths with zero hesitation.

The Lightning Automatic Tool Changer delivers 1.2-second tool-to-tool swap times with a bidirectional random-access carousel. A servo-driven magazine arm ensures precise tool pot positioning.
Standard with a 40-tool magazine (expandable), featuring integrated LED lighting for instant tool verification and manual control panel for diagnostics.
ATC Technology Details
Every Micro Dynamics machine is engineered around the operator. Wide double doors provide unobstructed access for fast part loading. The optimized table height of 43.6 in minimizes operator strain during extended shifts.
Full chip enclosure with safety interlock, centralized coolant and air gun stations, and intuitive control panel placement for a fatigue-reducing workflow.
Ergonomic Design Philosophy
The direct-drive built-in spindle delivers 15,000 RPM with 41.6 HP peak power and 104 ft-lb cutting torque. The motor is thermally isolated from the spindle housing, eliminating heat transfer that causes Z-axis growth in belt-driven designs.
Equipped with hybrid ceramic bearings (2.8 in mm inner diameter) and dual-contact 40-taper tool clamping (1,200 kgf), the spindle achieves superior surface finishes at high RPM while maintaining rigid heavy cutting capability.
Spindle Engineering
The MEGA 20VT trunnion is built for high-accuracy simultaneous machining with torque-motor drive technology.
