MAXI - Travelling column grinding machine

Product catalog summary
Overview: The MAXI line of surface grinding machines is engineered for high production capacity and precision, featuring advanced technology and a modular design. These machines utilize a travelling column architecture (T-line) to ensure consistent geometric precision.
Specifications: The machines offer maximum transversal grinding dimensions of 750, 775, and 1000 mm, and longitudinal dimensions of 1200, 1500, 2000, 2500, and 3000 mm. They are constructed with thick ribs in stabilized Meehanite cast iron for enhanced stiffness and stability.
Design and Engineering: Optimized through finite element analysis with the Politecnico di Milano, the machines feature hydrostatic lubrication on all axes, eliminating sliding friction for smooth, wear-free operation even at low speeds.
Spindle and Drive System: The spindle is powered by a variable-speed motor (15-18 kW) and supported by a no-wear hydrodynamic bearing at the front and precision ball bearings at the back. Precision ground ball screws with preloaded double nuts ensure stable axis positioning.
Automation and Control: The CN unit manages operations, allowing easy programming of automatic grinding cycles, including rough and finish grinding, spark out cycle, and automatic dressing. A CNC control unit is available for higher automation, facilitating wheel shaping and enhanced operational control.
Ergonomics and Safety: The machines feature an ergonomic design with a low-profile platform for easy loading and unloading. An integrated ecological enclosure ensures safety and provides a clear operational view, while centralized controls on an adjustable console enhance operator ease and safety.
Control Systems: The CNC unit offers superior automation, facilitating wheel shaping. The software simplifies programming of automatic grinding cycles through a guided menu, allowing parameter modifications during the cycle.
Operational Phases: The grinding cycle includes roughing, finishing, sparking, automatic dressing with real compensation for wheel consumption, and table and axis clearance at the end of the cycle. A self-diagnosis system provides control and visualization of potential anomalies through alarm messages.
Accessories: Accessories include a hydraulic oil cooling system, electric-box air conditioner, vertical grinding attachment, halogen lamp, industrial diamond, mechanical cleaner, dust extractor, grinding wheel, electronic wheel balancing, and more.
Technical Features: Detailed dimensions and specifications for different models are provided, including maximum grindable surface, table surface, work speeds, spindle rotation speed, spindle motor power, and machine mass. Technical data and features may change.

MAXI - Travelling column grinding machine-2

MAXI sono interamente costituite da strutture a doppia camera rinforzatecon nervature di grosso spessore realizzate con fusioni di ghisa Meehanite stabilizzata e caratterizzate da un elevato coefficiente di smorzamento per conferire la massima rigidezza e stabilit al sistema. Le guide della testa portamola appoggiano per tutta la loro lunghezza e lungo tutta la corsa verticale su quelle del montante; quest ultimo rimane per tutta la corsa a completo contatto con il basamento tra- sversale. Lo stesso discorso vale per le guide della tavola portapezzi che, anche a pendolamento longitu- dinale massimo,...
