WHAT’S NEW Brushless DC motor
How to fit 170W of power in a 40 x 80 mm, palm-sized housing is demonstrated by the new brushless direct current motor from maxon motor.
Its new EC 40 has a neodymium permanent magnet, stainless steel
housing and welded flanges. It boasts flat speed/ torque gradient (approximately 3.6 rpm/mNm), mechanical time constant 2.1 ms, permissible speed of 18000 rpm and 89% efficiency. The ironless winding reportedly offers extra quiet running and high stall torque. The motor can be combined with numerous components such as encoders or gears. The AB 32 permanent magnet brake has been added to maxon’s modular system. This is designed for operating temperatures of -40 to +100°C and is perfect match to the EC 40, says the company. A range of compatible controllers, from 1-quadrant and 4-quadrant servo amplifiers to programmable positioning controllers, make the EC 40 a multi-talented high-power unit, states maxon.

New coatings facility in Galway
Metal Improvement Company has opened a new parylene coatings facility in, Galway, Ireland. Ben Hayes, its UK and Ireland Regional Sales Manager explained that the facility will specialise in the application of parylene PVD coatings. The company already has many years’ experience of providing this type of coating through its existing Parylene Coating Services Division in Texas, USA. The facility will initially provide employment for up to 20 people and will be the base for more expansion and introduction of other material treatments into Ireland’s manufacturing sector. A one-day seminar marked the official opening of the plant in March. At this, Professor Liam Hunt of the University of Huddersfield spoke about development and measurement of biofunctional surfaces.

Package strength burst tester
The Mark 5 version of the Medical Engineering Technologies’ Mini Burst Tester has now been released. It is specifically designed for verification of sterile barrier seal strengths in cleanrooms and quality assurance laboratories. It performs burst tests as described in ASTM F2054 and ASTM F1140. Packs are inflated and the peak pressure achieved is displayed and recorded. The equipment now features an RS232 data output and a sensitive flow control to adapt the inflation rate to the volume of the package. With a test cycle time of approximately 10 seconds, validations and qualifications can be rapidly completed.

Accurately picking the spot
The new version of Gillard’s Servo- Torq rotary cutter is specifically designed to cut cuffed, corrugated,
taper and bubble medical tubing. The machine uses
a digital camera system to locate the transition points along the tube to ensure that every cut takes place where it is supposed to. Depending on the type of tube, this is normally in the middle of the cuff or equidistant between two bubbles. The company says that many tube products contain a mix of good cut lengths and scrap pieces. Special software has been developed to allow the operator to program in the exact sequence of good cuts that are required. The latest AC brushless servo motors are controlled by a digital Siemens three-axis drive system. This allows cut point accuracy to be held to within ± 0.25 mm, according to Gillard. The integral Accra-Feed caterpillar infeeder/puller belt unit can also be used to draw the tube from the extruder. Gillard claims that linespeeds of up to 250 m/min can be handled.

Inspection software options
Inspection and measurement company, Vision Engineering has introduced two new software options for its Mantis Elite-Cam stereo microscope. The system comprises a standard Mantis Elite
with a factory integrated and sealed USB2.0 digital camera that allows simultaneous optical and digital viewing. Both software options, ViFox and ViAxos, enable images
to be stored as JPG, BMP, or PNG files, and provide 2D measurement of features including lines, circles, areas and angles. The intuitive ViFox software allows users to easily set critical parameters whilst viewing the live image and in this way provides fast, precise imaging of samples and components. ViAxos offers advanced 2D measurement options such as feature-to-feature measurement and a digital zoom option so that individual features can be inspected in greater detail.
