Compact hexapod

The 6 degrees-of-freedom (DOF) positioning system provides precise translation in the X, Y, and Z directions and rotation around each of these axes within a compact, stiff platform. It is suitable for addressing space constrained, multiple DOF applications that require fine positioning resolution.

Features include:

• Minimum incremental motion of 20nm in X, Y, Z and 0.04 arc sec in ?X, ?Y, ?Z

• Payload lift capabilities up to 7.5kg; back-driving resistance to 100N

• Ample range of motion for simple integration into complex applications

• Multi-axis (servo, stepper, piezo, & more) motion coordination using Aerotech controllers

• Easy to control, program with virtual pivot point adjustment

Automated deep hole drilling machine

Nagel/TBT DM 50 twin spindle deep hole drilling machines now come with several automation upgrades. Consisting of two completely independent stations, it can be tended manually or with a fully enclosed integral robot housed inside the machine base. The machine can drill bores from 0.6mm to 12mm diameter, includes spindle speeds up to 24,000rpm, and features servo part counter rotation and torque sensing for automatic detection of contact between part and drill bushing.

The Nagel/TBT DM 50 with integral robot is specifically designed for automating low-volume, high-mix production requirements. With a robot overhanging from a bridge on top, the machine uses little additional floor space. Finished trays can be removed and green trays loaded when the machine is running to improve productivity. The machine can be run in manual mode, bypassing the robot for very low volume applications.

Protect, seal medical electronics

Three new low-pressure molding (LPM) materials – Loctite PA 6732, Loctite PA 6682, and Loctite PA 6951 – seal and protect medical devices from moisture, temperature extremes, chemicals, vibration, impact, and other environmental concerns.

LPM hot melts allow manufacturers to produce complex and intricate assemblies by customizing par t geometry, surface texture, color, and opacity. These materials form an adhesive bond with the entire component being encapsulated, becoming part of the component’s three-dimensional form and creating a water-tight, chemically resistant seal. The cost-effective LPM process involves three steps: placing the bare component into a custom mold set, heating the polyamide material and injecting it at low pressure into the mold, and allowing the material to cool rapidly for 10 to 50 seconds before removing for immediate use.

Loctite PA 6732 is an amber material that performs well in temperatures from -40°C to 140°C. Clear Loctite PA 6682 is designed for use in temperatures between -25°C and 105°C. Loctite PA 6951 is a colorless material that performs well in temperatures from -40°C to 100°C.
