Small Size... Plenty of power
Designed for high productivity with precision tolerance is Doosan Infracore’s DNM 400a vertical machining center. Built to fit the most crowded shop floors, it is available for less than $70,000.

The DNM 400a’s rugged, one-piece casting is strategically ribbed to prevent distortion during heavy or interrupted cuts. Fine grain Meehanite is selected for excellent dampening characteristics and the ability to dissipate heat. Widely spaced linear guideways give excellent support to the saddle in all locations, regardless of the table’s load distribution. Each guideway is induction hardened and precision ground. Rapid traverses are 1,181ipm along all three axes.

Powering the DNM 400a is a 15hp spindle motor that drives ISO#40 taper tools at speeds up to 8,000rpm, while delivering 52ft/lb of torque. The cartridge-type spindle is supported by precision-class, permanently-lubricate bearings. A heavy-duty drive belt eliminates slippage, reduces vibration, and contributes to thermal stability.

A 20 station, double-arm ATC changes tools in a quick 1.3 seconds. The Big Plus dual-contact tooling system creates full contact along the spindle taper and the toolholder flange. This assures maximum rigidity for greater precision and longer tool life. Both Big Plus and standard toolholders can be mounted at any ATC station with no need for special adaptors.

The 86.7" x 87.2" footprint is perfect for buildings with standard 8ft x 8ft doors, while maximum part size is 25.0" x 17.1" x 20.1" and 881 lb.

Additional features of the DNM 400a include rigid tapping capability, an auger-type chip conveyor, cooling and lubrication systems, a program and data protection key switch, and a portable manual pulse generator with movement in increments of x1, x10, and x100 to make fixture or part alignments quick and easy. The color controller is a Fanuc Oi-MD.

Closed-Loop Linear Motion Module
The latest product in the M3 Micro-Mechatronics Module family is the miniature M3-L closed-loop linear motion module. With 0.5µ position resolution and a total package size of less than 27.5mm x 13 mm x 7.5mm, the M3-L module is the smallest, highest-resolution closed-loop linear motion control system on the market.

It is ideal for use in fluidics and valve controls; microsurgical manipulation; and precision photonic and optical controls in a diverse array of biomedical products, such as lab instrumentation, portable medical devices, and endoscopic surgical devices. 

All motion and control functions are fully integrated into the M3-L module, including a piezoelectric linear micro-motor, position sensor, guide mechanism, motor driver, control processor, and software. The module runs on 3.3V input for battery-powered operation. The standard serial interface (I2C or SPI) accepts PID closed-loop system tuning parameters, as well as high-level input commands such as ‘move specified distance.’ No external controller is required. The M3-L module is available with a bullet nose for pushing or a hook tip for pulling loads. Typical travel range is 6mm. New Scale also develops custom OEM modules including bi-directional (push/pull) systems, modules with custom travel range up to 20mm, and multi-axis configurations. The M3-L module draws approximately 500mW of power while moving and 200mW quiescent. Weight is approximately 4.5g without tips.

M3-L production modules are customized to OEM specifications. Pricing and delivery depends on specifications and volume. Custom prototypes are available in as little as eight weeks after acceptance of proposal. RFPs can be submitted online atnewscaletech.com/contact_M3-L-RFP.aspx.

Vertical Configuration, Digital Optical Comparator
VisionGauge Digital Optical Comparator is available in a vertical configuration. In the vertical configuration, parts are mounted flat on the system’s X-Y stage and the optical axis is vertical – the lens is looking down on the parts. The most appropriate VisionGauge configuration for a given application – either horizontal or vertical – is typically dictated by fixturing and mounting considerations. For example, early adopters of the vertical configuration of the VisionGauge Digital Optical Comparator include mobile and smart phone manufacturers, as phones can be laid down flat on the vertical configuration’s X-Y stage. Another application appropriate for the vertical VisionGauge is the inspection of cranio-maxillofacial implants in the orthopedics industry – also difficult to fixture in a horizontal system. Standard X-Y travel for the vertical configuration is 12" x 12" and extended 24" x 24" travel is available as an option.

All of the standard options available for the horizontal configuration of the VisionGauge Digital Optical Comparator are also available for the vertical configuration. The list of available options includes:

  • Reflected illumination,
  • Laser module for Z-axis measurements,
  • Motorized rotary fixtures, and
  • A fifth monitor for automatic recall of related documents such as part prints and more.
