Drones might one day be fully capable of operating autonomously in complex, confined spaces and legal requirements and regulations must be modified to allow for far-range civilian drone use.

Aerotech QNP-Z series piezo nanopositioning stages provide the resolution, linearity, repeatability and high dynamics required for applications ranging from microscopy to optics alignment, according to the company. The stages offer resolution to 0.15nm, linearity to 0.007 percent and repeatability to 1nm. With high dynamics (resonant frequency and stiffness), users can achieve higher throughput in exacting processes, and a variety of travels (100μm to 600μm), feedback options and vacuum versions are available.

Kipe Molds’ patented micro injection molding system integrates an injection system directly into a cold runner system, allowing the system to be used on any machine or as part of a two-shot platform, according to the company. As a result, Kipe can produce and sample or run flash free silicone micro parts in its Class 100 clean room.

A new whitepaper from Aerotech, titled “Laser Raster-Scanning Patterns on Cylindrical Workpieces Using CADFusion and PSO Bitmap Tools,” is now available. The paper examines the tendency of cylindrical laser processing applications to program the laser writing campaign as if the two axes (linear and rotary) are both linear in nature, effectively “unrolling” the cylindrical pattern to make the shape a more typical flat workpiece. The paper examines shortcomings of this approach, as well as some alternatives.

Master Bond LED401LV is a one-part LED type system that will cure when exposed to a light source emitting 405nm wavelength and where the presence of any UV light is minimal or incidental. When exposed to the light, LED401LV will cure completely tack-free in sections 1/8" thick or more. The system can be used as an adhesive, sealant, coating and encapsulant, according to the company.

The De Beers Group of Companies has acquired a 33.4 percent equity stake in Synova SA, a Swiss-based supplier of laser micro jet (LMJ) technology. The technology has the potential to help diamantaires achieve higher yields, reduce the risk of damage to stress stones and generate higher throughput due to faster cutting time and easier processing.

Microcut's 140-page catalog of microscale cutting tools is available for download at its website. Items include 3-flute, long-shank endmills from 0.015" to 0.125" in diameter and carbide microdrills from No. 92 to 0.125". Included is a full selection of amorphous diamond-, CVD- and PCD-coated endmills, high-performance endmills and specialty cutting tools. A large inventory ensures same-day shipment of stocked items.

Aerotech piezo nanopositioner thumbAerotech Inc. says its QNP-XY series piezo nanopositioners provide the resolution (0.15nm), linearity (0.007 percent), repeatability (2nm) and high dynamics required for demanding applications, such as microscopy and optics alignment.

Hassay Savage cobalt rotary broaches thumbHassay Savage Co. offers M-42 cobalt rotary broaches in inch and metric sizes. They are effective for difficult-to-machine high-alloy workpiece materials. The broaches are suitable for all CNC and Swiss-style machine tools, according to the company.

Albright Technologies Inc. provides silicone micromolding services. According to the company, it has developed the in-house capability to complete 3D CNC machining at a microscopic level, allowing for the design of aluminum mold tools for microparts.

Mold tools, prototypes and production microparts are all manufactured at the company’s Leominster, Mass. facility, with a standard turnaround time of 15 business days for micromolds and engineering samples.
