CNC Turning Centers

We’ve been known for CNC Turning Centers for over four decades and have installed tens of thousands in North America and around the globe and A.W. Miller Technical Sales has been providing service from each of our technical centers located in Buffalo, NY | Toronto, Canada | Montreal, Canada | Pittsburgh, Pa. The range of applications seems endless, from small part turning to jumbo heavy-duty cutting. Production quantities from thousands per week to single pieces. Below, we’ve arranged our CNC turning products by series, with an explanatory paragraph about each one’s capabilities and solutions. Multi-Tasking capabilities are part of many of these CNC turning products. Please click on the photos to learn more about each family.

On-machine programming is based on question-and-answer dialogue between the operator and control – in English. The Mazatrol CNC already contains a database of recommended cutting speeds and feeds, tool management, tool path checking and 3-D solid simulation of the cutting program, making programming intuitive even for less experienced operators. As cutting tool performance is improved, new parameters may be easily incorporated into the tool database and applied across all programs.
Mazatrol is the fusion of CNC with PC to allow networking of a machine, or an entire plant. This offers opportunities to program off-line, schedule production, monitor each machine remotely, receive alarms, schedule maintenance, and more.

Hyper Variaxis NEW

The HYPER VARIAXIS 630 incorporates the most advanced technology available to provide unparalleled performance
The HYPER VARIAXIS 630 is an advanced 5-axis Multi-Tasking machining center that continues the company’s philosophy of Done-In-One manufacturing. The machine is the first to incorporate a revolutionary design by Ken Okuyama, a world-famous industrial designer.
The HYPER VARIAXIS 630 incorporates the most advanced technology available to provide unparalleled performance. Linear roller guides are used on the X-, Y- and Z-axes, ensuring high-accuracy positioning and rapid traverse rates of 262.5 ft/min. A 150-degree tilting trunnion (A-axis) carries a full 360-degree rotating table (C-Axis) to enable complete machining of parts in a single setup.
The new Mazak MX Hybrid Roller Guide System is integrated into the HYPER VARIAXIS 630 to deliver levels of durability and reliability that result in long-term accuracy. The Mazak MX Hybrid Roller Guide System increases vibration dampening to extend tool life, handles higher load capacities, accelerates and decelerates quicker to shorten cycle times, consumes less oil for “Greener” operations, and lasts longer with less required maintenance.
The sixth-generation Mazak MATRIX CNC is capable of full five-axis machine control and of processing the massive amounts of data associated with sculptured surfaces and fine details. It provides high computing speed from its 64-bit, twin-engine CPU to support sub-micron resolution and program sizes up to 8MB. A popular option is MAZACC-3D software for generating the finest, most accurate surfaces on critical parts. This extensive look-ahead feature in Mazak MATRIX recognizes severe changes in machining direction on-the-fly and optimizes the acceleration and deceleration parameters to maintain accuracy and surface finish integrity.
