Meet the team – Dave Whitmell revisited

London Swim 2011

There is an ulterior motive to repeating my ‘meet the team’ which I will explain at the bottom of the page.

A lot has happened since 2003. Although my work position at Micromech has not changed I have achieved a certification in IPC/WHMA-A-620 as reported in the Micromech web news in June 2011 (click for details).

Peter and Robert who were then 12 and 8 when I did my last ‘meet the team’ have of course grown up. My eldest Peter has now graduated From Warwick University and is working as a Teacher in Cambridge. Robert is now doing his A levels in the 6th Form. In the summer he is helping out at the Olympics, and lucky me, I have managed to get a ticket for the events where he is working.

            Pete’s Graduation 2011           

Frances and I have now celebrated 26 years of married bliss. She is now a Teaching Assistant, which is something she has wanted to do, and she loves.

Things have changed as far as my swimming is concerned as I have stopped the Masters but I am working to get back to it by swimming at a local gym. When I gave up the Masters swimming, my waistline increased, the weight just pilled on. I am now ‘trying’ to address this little problem through the Slimming World.

With my water colour paintings, I have given a few away; to family and work colleagues, hopefully they have hung them in prime position in their homes.

Over the years I have lost both a good friend and my father in-law to cancer, and now my stepfather is recovering after having surgery to remove part of his liver. In addition to this, my father died of a heart attack 30 years ago at the age of only 49, I have therefore decided it is time to do some fund raising.

The event’s I have chosen are:

British Gas Great swim London on the 26th May
British Gas Great swim Manchester on 30th June
Annual Walk in Wales weekend of 16-17th June.

The annual walk has been taking place over the last ten years; it started when a group of dads at a local football club decided it would be a good idea to taken their sons on a weekend hill walking. Over the years we have climbed Snowdon, Ben Nevis and many other Mountains. Peter, one of the dads who organised the walks, passed away last year. It was appropriate that this years walk is dedicated to him. His sons will also be taking part.

The Charities I have chosen are:

The British Heart Foundation
Helen Rollason Cancer Charity

I guess by now you have easily figured out my ulterior motive for a ‘meet the team’ update. Clearly I am too late for my first event but if you would like to sponsor me for one of the events or perhaps both of them, please click on the links on the events to make your offer.

Many thanks

The machine that machines the parts for precision machines often uses a direct drive or frameless motor

Manufacturing the gears or any other parts that go into a precision machine requires a machine that needs to operate at the very pinnacle of precision. If the parts produced are less than perfect then clearly any number of manufacturing businesses suffer the consequences.

Consisting of a rotor, stator and high-resolution feedback device, the DDR cartridge motor uses the machine’s bearings to support the rotor. An innovative compression coupling engages the rotor to the load and the frame of the direct drive mounts to the machine with a bolt circle and pilot diameter just like a conventional servomotor. This saves space and design time and simplifying the overall system.

The KBM is directly coupled to the machine’s load offering exceptional direct drive rotary benefits over traditional mechanical transmission systems. By eliminating the compliant components of the system, such as gearboxes, timing belts and pulleys, KBM motors increase machine throughput, reduce noise and reduce maintenance requirements to extend a machine’s useful life. These benefits are provided in a compact, yet high-performance, footprint, which allows OEMs to design smaller, more cost effective machines.

Direct Drive for the Perfect Cut Direct drive technology allows gear grinding tools, precision lathes and other machine tools to operate with the greatest possible precision and repeatability. By completely eliminating the need for transmission components, direct drive motion makes a machine simpler while reducing maintenance. And direct drive eliminates transmission backlash, chatter and compliance, so that every cut is exact, every time.
Maximum Performance with a Minimal Footprint Direct drive technology allows the motor to be located directly in the machine head, applying the required velocity and torque directly to the cutting tool. To meet the space and weight constraints of this approach these motors offer the widest torque range in the smallest possible package with the greatest installation flexibility. For this reason Kollmorgen developed the Cartridge DDR® technology to simplify things even more, enabling a simple five-minute installation process for mounting the motor and coupling directly to the load.

The Cartridge DDR™ direct drives and the KBM frameless motors consistently wins this business because it provides significant value to the customer due to greatly reduced parts count, resulting in improved simplicity and reliability. This also means reduced maintenance with the added advantage of increased accuracy for market leading registration.

SPYRAFLO ON TARGET WITH WEAPONS TRAINING SYSTEM

A leading supplier of integrated live fire and virtual weapons training systems for unmanned land and sea vehicles, aerial targets and electronic scoring devices turned to Spyraflo to help with their latest project. Given the mission-critical function of these systems for military security forces there is an overriding need for reliability, consistency and high-level system performance. To that end they have been designing Spyraflo bearings both into its individual stationary infantry target system and its stationary armoured target battle target systems. These are articulating mechanisms that achieve the long-term durability required, meeting and even exceeding their customers’ demands in respect of reliability.

Some 10 years ago this manufacturer selected Spyraflo’s flange-mounted, self-aligning bearings for one of its systems for the purposes of small arms training in the military. This was their most popular small arms training unit in the world, with over 30,000 units fielded to date.  After experiencing continued success with the Spyraflo bearings they felt confident enough to replace the bearings with another one of our important products, which was used for live fire training and qualification programmes.

The original bearings in the equipment were not sealed in any way and contamination in harsh and difficult environments led to poor bearing performance. The answer, it transpired,  was simple: a custom-designed 60mm diameter bearing from Spyraflo. After discussing the problem with Spyraflo engineers the solution was to use the self-aligning, fully sealed, flange mounted, Teflon Bronze bearing.

These leak-proof bearings are produced with corrosion-resistant aluminium housing and zinc plated steel components. The bearing also incorporates a ±5° self-aligning capability that provides the necessary shaft alignment when dealing with welded fabrications. This patented feature translated into ease of motion, while increasing the bearing’s durability and in addition enabling an extended product lifespan. A further benefit of the Spyraflo bearing is that there is no pre-assembly greasing and other preparation work is no longer required.

Micromech is the UK and Eire distributor for these intelligently designed bearings, if you would like more information about them or if desired, a sample, then contact Alan Spinks on 01376 333333 or email alan@micromech.co.uk

‘A revolution in bearing Solutions’

Direct Drive Motors on winder machines results in ‘less is more’

The Kollmorgen’s Cartridge Direct Drive Rotary™ (DDR) motors offers a rotary direct drive system solution that allows OEMs and end-users of winding machines to achieve significant competitive advantages. Consistently, the system enables 20% higher machine uptime and 30% more throughput than motor-gear solutions. At the same time, it features 40% fewer components and on average, generates a 20% lower service cost.

Significant improvements can also be achieved in acceleration and positioning accuracy, reliability, smooth running, servo drive properties, energy efficiency, and noise development. Over the entire life cycle, the Cartridge DDR motor can generate cost savings of up to 50%. They also offer further numerous advantages, not only compared to motor-gear solutions, but also in comparison with other rotary direct drives with no housing. Since they represent a standard solution, which is also extremely variable and flexibly adaptable, no individual components have to be modified to each other, then integrated in the development and production of the machine.

Consisting of a rotor, stator and high-resolution feedback device, the motor uses the machine’s bearings to support the rotor. An innovative compression coupling engages the rotor to the load and the frame of the direct drive mounts to the machine with a bolt circle and pilot diameter just like a conventional servomotor. This saves space and design times and simplifies the overall system.

Furthermore, no additional costs are incurred which are typical of other special solutions, given their significant time-consuming and labour-intensive assembly and more expensive test phase. At the same time, the risk of technical incalculability is also lowered.

Combining Cartridge DDR motor with Kollmorgen’s versatile AKD™ servo drive can improve the machine performance even further. The motor data stored in the AKD as well as sophisticated control algorithms permit greater precision, optimised energy usage and more productivity. Due to pre-configured motor data and feedback device data, the installation and commissioning is further facilitated and accelerated.

A sophisticated modular system enables the Cartridge DDR to be tailored precisely to customer requirements. Five frame sizes, 17 different lengths and 52 standard windings are available, while the nominal torque values range from 4 to 510Nm, reaching a peak torque of up to 1,090Nm, and speeds of up to 1,500RPM.

The Cartridge DDR motors combine the space-saving and performance advantages of a frameless motor with the ease of installation of a full-frame motor making them ideal for winding machines. Besides these machines, the Cartridge DDR motors are used in numerous other applications such as material punching and forming, printing, moulding and sealing.
