Multi-axis Machines Redefine What’s Possible so You Remain Competitive
The versatility and single setup functionality of multi-axis machines supports faster machining cycles with reductions in downtime.
Posted: January 20, 2025
Redesigns and innovations developed by suppliers result in a fresh approach to the precision and productivity of 4-axis and 5-axis machining capabilities.
New 5-axis Milling Machine Expands with Production Needs
To grow as production needs increase, the design features of the new MILL P 800 U S full 5-axis milling machine from GF Machining Solutions (Lincolnshire, IL) provide for easy, seamless automation integration. As a flexible and scalable solution, shops can start with a simple standalone MILL P 800 U S, then expand their production capabilities into fully automated multiple-machine cells.
The MILL P 800 U S is a more compact machine with a reduced footprint and is engineered specifically for automation. The company relocated the electrical cabinet from the back of the machine to its lefthand side, thus allowing for direct robot loading from the rear of the machine. Prior to the design change, a robot would load parts on to one of the pallets of the machine’s two-pallet changer. Now, there is no pallet changer, and the robot arm itself moves into the machine with a pallet of loaded workpieces.
In terms of operator ergonomics and accessibility, having the automation in the back frees up the front of the machine for the operator and makes for a safer work environment. Automating from the back also helps reduce the entire footprint of a cell.
For increased stability and precision, GF Machining Solutions engineered the machine as a unique full twin-ballscrew drive/twin-linear scale gantry machine. The twin drives compensate for any imbalanced cutting forces between the two drive torque motors on each gantry side, while the twin linear scales ensure both gantry axis ends are always synchronized.
The MILL P 800 U S features a torque-motor driven rotary/tilt trunnion-style table that contributes to the machine’s continuous full 5-axis simultaneous movement for smooth part surface contouring. The StepTec spindle features a maximum speed of 20,000 rpm, an HSK-A63 interface, torque rating of 120Nm and power output of 36 Kw.
Next-generation CNC Machine Control
The all-new Okuma America Corp. (Charlotte, NC) OSP-P500 CNC control, an advanced open architecture system, is designed exclusively for Okuma machines. The control system enables numerous market-leading intelligent machining technologies, including:
- Greater processing power with dual-core computer processors.
- Embedded, robust cybersecurity features to protect operations and data.
- On-board energy management green machining capabilities.
- Windows®-based, open-architecture platform for easy integration to applications on the Okuma App Store and beyond.
- Full-color touchscreen in two sizes: 15” screen or 21.5” screen, based on machine model.
The Okuma OSP suite of machine controls offers various technologies that support intelligent manufacturing processes, including the Okuma Connect Plan machine status and performance monitoring software.
At IMTS 2024, Okuma demonstrated the control on the GENOS M560V-5AX (5-axis), which was paired with the new Okuma Robot Loader and Automatic Tool Changer. The GENOS is a fully equipped 5-axis machine with a double column structural design.
Redesigned Vertical Machining Center Delivers Next-level Precision and Productivity
The full simultaneous 5-axis VARIAXIS i-700 NEO Multi-Tasking Vertical Machining Center from Mazak Corp. (Florence, KY) provides accurate single-setup processing of parts with complex profiled surfaces. As part of the NEO family, the machine is enhanced with Mazak’s powerful SmoothAi CNC along with faster machining cycle times, expanded workpiece capacities and more automation options.
The VARIAXIS i-700 NEO features a spacious Y-axis travel of 43.31″ (1,100 mm) and X-axis travel of 24.80″ (630 mm), which easily accommodates workpieces up to 33.45″ (850 mm) in diameter (single table) and 19.67″ (500 mm) high. With 360° of rotation in the C axis and +30° through -120° of tilt in the A axis, its roller gear cam-driven rotary/tilt table is supported at both ends and provides stable high-precision machining.
The design of the VARIAXIS i-700 NEO’s 18,000 rpm, 40-hp (30 kW) 40-taper standard spindle helps increase the machine’s Z-axis stroke to 23.62″ (600 mm) and reduces interference. This allows for optimal part reach without having to use longer length tools. For high-speed and high-torque applications, Mazak offers 16,000-rpm, 62-hp (46-kW); 20,000-rpm, 40-hp (30 kW); and 20,000-rpm, 56-hp (42 kW) spindle options for the VARIAXIS i-700 NEO.
A space-saving 30-tool automatic tool changer provides easy access and allows for unattended machining to boost machine utilization. For additional capacity, there are 40-, 80- and 120-tool changer options available.
For sustained high-speed operation, temperature-controlled cooling oil circulates through the machine’s ballscrew cores, while Mazak’s SmoothAi Thermal Shield system automatically determines and applies compensation according to machine temperature changes.
Horizontal Machining Centers: Productivity, Precision and Sustainability
The new INH 63 and INH 80 horizontal machining centers from DMG MORI Manufacturing USA (Hoffman Estates, IL) set new standards in horizontal machining. In combination with MX – Machining Transformation from DMG MORI, the two models support users on their way to a sustainable, efficient and competitive future of CNC manufacturing. The horizontal machining centers are designed for demanding components in tool and mold making as well as in the energy and green tech sector — including, for example, drive technology for electromobility. The focus is also on complex parts for the aerospace sector. The INH 63 can handle 630 mm pallets, while the INH 80 is designed for 800 mm pallets. With their stability, precision and machining versatility — they are available in a 5-axis version — the two machines act as the perfect foundation at all levels of the machining transformation. They allow a high degree of process integration, can be flexibly automated and are optimally prepared for the DX – Digital Transformation.
Both horizontal machining centers are also characterized by their wide axis ranges, which ensures efficient chip removal. The INH 63 and INH 80 are impressive from light machining to the high-load range. As standard, they have a powerMASTER spindle with a speed of 12,000 rpm and a torque of 808 Nm. Spindles with up to 16,000 rpm or 1,414 Nm torque (8,000 rpm) are optional. In all three cases, a long warranty of 36 months applies with no limit on running time.
In the 5-axis version of the new INH machining centers, the swivel rotary table has large bearings and two high-performance torque motors as the A-axis. This eliminates backlash and ensures maximum precision. The ergonomically accessible work area is so large that it offers sufficient space even for overhanging tools. With the ability to machine negative angles, the INH 63 and INH 80 meet an essential requirement in die and mold making. The table can also be fully swiveled through 180°. This enables “upside down” machining and creates immense advantages, particularly for the use of milling-turning technology.
