Vertical multi-process grinding with integrated automation and thermal stabilization

The Vertical Mate 55 2. Generation is a CNC vertical multi-process grinding machine designed for high-accuracy processing of internal diameters (ID), outer diameters (OD), and faces within a single chucking operation. It is engineered for precision-critical sectors including aerospace, automotive, semiconductor manufacturing, and machine tool production.

Enhanced thermal stability and mechanical precision
To address the requirement for consistent dimensional accuracy in high-mix production, the machine base structure was redesigned using Finite Element Method (FEM) analysis. These structural optimizations, combined with vibration testing, have resulted in a 60% reduction in the influence of heat on dimensional changes compared to previous models.

The system achieves a roundness accuracy of 1.0 µm. This precision is maintained through the standard inclusion of an automatic in-cycle part measuring device and a Z-axis scale. The integration of these components allows for real-time compensation and verification of technical tolerances during the grinding process.

Spindle performance and energy efficiency
The machine utilizes the speedMASTER grinding spindle, which provides a maximum power output of 18.5 kW and a torque of 36.8 N·m. With a maximum rotation speed of 18,000 min⁻¹, the spindle supports diverse grinding applications while improving processing efficiency.

Total power consumption has been reduced by 21% compared to the first-generation model. This gain in efficiency is attributed to the combination of the speedMASTER spindle and the implementation of inverter control for the coolant pumps. Furthermore, the transition to a 400V specification removes the requirement for external transformers in many international markets, including the European region, simplifying the digital supply chain for global equipment procurement.

Vertical Mate 2. Generation Series with PH Cell 

Automation and process reliability

For applications requiring extended unmanned operation, the machine can be integrated with the PH Cell automation system. This modular pallet handling solution utilizes side-loading pallet transfer to maintain operator accessibility to the work zone. The PH Cell accommodates various pallet sizes and stockers, enabling the system to manage high-mix, low-volume production cycles during nights and weekends.

Reliability is further supported by a double-layer coolant tank design that improves fluid cleanliness and extends the intervals between coolant replacements. For environmental and maintenance standards, a zeroFOG mist collector is available to capture fine particles down to 0.3 μm, preventing the accumulation of airborne residues within the automotive data ecosystem and industrial environment.

Digital interface and security
The control system has been updated to the ERGOline X interface, featuring a large-screen touch panel. This digital platform integrates with the my DMG MORI service portal and uses DMG MORI Messenger for the visualization of machine operating conditions. Security is managed via whitelist-type software to provide protection against external digital threats without compromising system latency.
