Cutting Edge CNC Machining Centers

Computer numerical controlled machining centers have quickly become the go to method for producing complex mechanical components to exacting standards. Machining centers interface with computers to make finished parts that are nearly identical to the designer’s original vision. In addition, these parts can go from nothing more than a good idea to a tangible product in as little as a matter of days.

The very same factors that allow for such accelerated production also allow for product updates on the fly in much the same way as the accepted digital software paradigm. This means additional fiscal savings; seeing as a design flaw is constrained to a much smaller stock of units as opposed to a massive production run. In many cases, goods can be constructed from raw materials on a made to order basis, which lowers the often-prohibitive investment costs and encourages innovators to, well, innovate.

Early CNC Machines

The first CNC machines were mills that were constrained to operating only in the X and Y axis, and although revolutionary in the nineteen fifties, two axis mills would prove to be child’s play compared to the five axis mechanical monsters available today. Both the Makino D800Z 5-Axis Machining Center and the Ajax V700i 5X represent the cutting edge, no pun intended,  in CNC machining, but for distinct reasons.

CNC Machining Centers

Two New Amazing CNC Machining Centers

Beginning with the smaller and less expensive of the pair; the Ajax V700i 5X sports an 18 kilowatt ten-thousand rpm spindle, two-hundred liter coolant system, twenty-four tool magazine, a twenty-centimeter rotary table with an eighty kilo weight capacity, as well as an automatic 8-station turret, tailstock, automatic speed range change and Fanuc drives with the intent of pairing the Fanuc OiTD Mate touch interface with Turnmate i software. “[Its] the easiest to use on the market today, where a beginner is quickly able to pick up the use of the different cycles”

The V700i 5X is fitted with high specification iTNC 620 Heidenhain control and boasts a 12,000 rpm/20 bar coolant option, chiller, a 200 mm diameter rotary/tilt table, 24-tool magazine, has a table size of 800 by 400 mm and axis travels of 700 mm in X, 400 mm in Y and 550 mm in Z with the option of greater Z-axis travel of 650 mm.

Additional Machine Tool Features

In addition to the touchscreen feature, the machine, with full ISO programming, also has the ability to be used in manual cycle mode through the electronic hand wheel.  In terms build specs; the machine range is built on heavy-duty beds each with hardened and ground ways, and spans centre heights from 180 mm on the Evolution 3 AJEV 180 to 500 mm on the largest AJEV 500.

With the largest machine in the series weighing in at 10 tonnes and Bed lengths ranging from 750 mm to 5,000 mm there is a model in this series to suit most light industrial applications while maintaining a price point that proves neither to be prohibitive, nor restrictive, to small independent ventures

For larger applications something like the Makino D800Z is ideal for satisfying one’s 5-axis milling needs. “Large-part 5-axis machining presents numerous challenges, due to the size, weight and range of features found on large components,” says Bill Howard, VMC product line manager at Makino. “The D800Z 5-axis machine provides new levels of sustained dynamic accuracy, achieved through technologies that are very productive, yet minimize thermal influences and maximize volumetric accuracy.”

Improved machine Efficiency

What this all means for the end user is; higher efficiency, lower cost, increased surface precision,  and very low potential for collision damage. A number of spindle options ranging from 12,000 to 20,000 rpm offer adaptability for increased utility. Much like the aforementioned Ajax V700i 5x, Makino’s offering provides the unparalleled stability that is crucial for meeting precise specifications for machine parts. In fact, the entire system remains rock solid up to its 1,200 kilogram load capacity.

The Makino D800Z 5-Axis Machining Center and the Ajax V700i 5X are both testament to the wide range of options available to the modern machinist. It is truly a thrilling time to be a modern engineer with such a wealth of technology available at your fingertips. Since its inception in the aerospace sector CNC industrial technology has only proven that the sky is, in fact, far from the limit.
