Intertronics launches precision microdispensing
system for jetting liquids and pastes
Adhesives specialist Intertronics now supplies the
Vermes Microdispensing System (MDS)
1560, an easy-to use, cost effective jetting
valve for a wide range of viscosities,
including solder pastes. The product is based
on Dynamic Shockwave Technology (DST), a
revolutionary pneumatic actuator technology, which optimises
the valve’s yield to achieve more precise dispensing. Able to
dispense very small amounts in rapid succession, the consistent actuation
power delivers high precision, even at the smallest dispense stroke. The
Vermes MDS 1560 dispenses small volumes of material at fast speeds with
accuracy and repeatability, including onto 3D surfaces. It offers a high clock
frequency (around 500Hz) and dispensed shot sizes down to around 1nl.

SKF reveals Silent Series ball bearings for spindles

The Silent Series super-precision angular contact ball
bearings have been developed in direct response to key
issues faced by manufacturers of machine tool spindles. They
identified that minimising noise and vibration levels
during operation was key to improving confidence in
the performance of their spindles. Bearing cages in
lower-speed spindles can make rattling noises during
rotation. This is normal, but can be mistaken for a
sign that something is wrong with the spindle or its
components. Rudolf Groissmayr, product line manager
at SKF says: “The SKF Silent Series feature a new
and innovative polyamide cage centred on the balls
that minimises this ‘cage rattling’ during rotation. Their
silent operation increases the confidence of the end-user
in the quality of spindles.”

Size 6 brushless slotted DC
motors for arthroscopic applications

Motors for arthroscopic applications need to be tightly packaged and offer
minimal vibration to achieve lightweight, ergonomic designs – a challenge
answered by the latest cannulated Brushless DC motors from Portescap.
The release of three new cannulated surgical motors for arthroscopic
applications offers engineers a solution with low vibration, high efficiency
and a proven ability to withstand 1,000+ sterilisation cycles – as well as
exposure to saline and other foreign materials. The new Portescap motors
are lightweight with low noise and vibration to maximise tactile response
and surgeon control in the most delicate of surgeries.
