Mazak upgrades VMC: Medical Manufacturing

Not satisfied with a popular five-axis vertical machining center in its lineup, a major machine builder came out with an enhanced version that reportedly offers an improved CNC, shorter cycle times, increased workpiece capacities and more automation options.

Main selling points of the Variaxis i-800 NEO VMC from Mazak Corp. in Florence, Kentucky, include the Mazatrol SmoothAi CNC. Relying on artificial intelligence, Mazatrol SmoothAi features a function called Smooth Machining Configuration for process optimization. SMC allows real-time operator control of numerous cutting parameters, according to Mazak.

With the launch of Mazatrol SmoothAi, the company introduced its optional Smooth Project Manager Gateway software. Working in concert with external CAM software, Smooth Project Manager Gateway gives CAM programmers access to internal machine data, allowing them to query the machine to download information, such as machine models, offset data, stroke limits and tooling configuration. (The last of which can be modified at the CAM workstation and sent back to the machine so operators can accurately complete a setup.)

With the downloaded information, Mazak points out that users can create more precise machine programs that take into account the capabilities and limits of each machine. In addition, the company notes that realistic program simulations with real-time setup information can be produced so even less experienced operators can have confidence when running complex machining programs.

Another enhancement based on artificial intelligence is Ai Thermal Shield. To maintain machining accuracy, this feature uses algorithms that learn from and adapt to environmental changes to compensate for heat-related displacement.

The Variaxis i-800 NEO can handle tool lengths up to 400 mm (15.75″) in magazines with capacities of 30, 40, 80 and 120 tools. The 80- and 120-tool magazines are equipped with a servodrive that can significantly reduce tool wait times, according to Mazak.

“We’re seeing as much as 10% shaved off tool-to-tool and chip-to-chip time because of the servo,” said Chuck Birkle, vice president of sales and marketing.

Other capabilities of the Variaxis i-800 NEO touted by Mazak include traverse rates of 42 m/min. (1,653 ipm) in the x-, y- and z-axes, which reduce cycle times, and increased axis strokes — to 730 mm (28.74″), 849.9 mm (33.46″) and 560.1 mm (22.05″) in the x, y and z directions, respectively — to accommodate larger workpieces.
