High-precision, modular gundrilling machine

Designed for drilling deep holes with smaller diameters, the UNE6 compact gundrilling machine is well suited for medical components such as bone screws and surgical instruments that require small-diameter, deep holes in high strength titanium or surgical-grade stainless steel. Featuring a counter-rotating-workpiece headstock for small parts, the machine offers enhanced concentricity. Hole diameters with the UNE6 can be drilled as small as 0.039" (1mm) with diameter-to-depth ratios of more than 100 to 1.

The UNE6 has a cast iron headstock and chip box components, cartridge spindles with premium quality bearings, and a high precision preloaded ball screw feed.

Modular UNE series gundrilling machines are available in a variety of configurations with up to four spindles, a single drilling module, dual spindle-spindle modules, and as single- or dual-module machines. The compact construction of the UNE6 allows for quick installation.

UNISIG provides customers with training for machine operation, process optimization, and gundrill tool sharpening.

Micro-universal hydraulic chucks

Precision hydraulic chucks from WTE Präzisionstechnik GmbH, a unit of the MAPAL Group, offer high radial accuracy and vibration damping. The chucks deliver improved surface quality, reducing microstructure cracking on the tool’s cutting edge and increasing productivity. The hydraulic chucks are manufactured with axial and radial adjustment in the most common shank forms. Using WTE reducing sleeves or hydraulic chuck extensions offers flexibility in the clamping tool as well.

Offered in the hydraulic chuck line are micro-universal chucks developed for high speed micro-machining up to 60,000rpm, delivering concentricity of <0.005mm. Chucks offer a clamping range from 0.2mm to 6.4mm.

AT-A-GLANCE

• Low interfering contour
• Safe, fast clamping
• Handles easily
• Wide range of shanks available
• Modular system
• Cylindrical extensions

10W DC-DC converters

The AEE10W-M series, 10W DC-DC converters provide OEMs with solutions for industrial and medical instrumentation equipment that requires a certified supplementary or reinforced insulation system to comply with industrial or medical safety standards.

Encapsulated in a 2" x 1" industry-standard package, the AEE10W-M series offers up to 92% efficiency and covers input voltages from 9VDC to 75VDC with three 2:1 input voltage ratings (9V to 18V, 18V to 36V, and 36V to 75V).

The series has fully regulated, single-, or dual-output voltage models.

The reinforced insulation system, critical for medical equipment applications, is rated for 300VAC working voltage and 4,200VAC RMS. The AEE10W-M series is certified to the 3rd Edition UL/CSA/EN/IEC 60601-1 medical safety standard and is rated for 2x means of operator protection (MOOP). This converter family has a calculated MTBF to MIL-HDBK-217F of greater than one million hours.

AEE10W-M specifications

• 5V and 12V single-output models
• +12/-12V and +15/-15V dual-output models
• Operate from -40°C to 75°C
• Full power is available to 60°C; power derating at higher temperatures
• Available in low-leakage current
• Protection from overvoltage
• EMI characteristics meet EN 55022, class A, and FCC level A
