SMOOTH AND RELIABLE COMPONENT PALLETISERSIEF Werner component palletising systems have proved hugely popular in mainland Europe and now they are available from us in the UK. They are designed to provide orderly and gentle transfer of the work pieces to and from modern assembly lines, often integrating end of line processes such as part marking and test. Four basic and fully programmable models complete the range, each with its distinctmerits, but allwith the abilityto be tailoredto suit theprecise needsof theapplication.This can rangefrom simplethree-axis,pick and placeto a multi-axishandling andcompleteturnkeysolution.

Yourchoices are:- varioSTACK, 1m2 footprint and the ability to load from the front or side

PSM, slimline system for integration into assembly lines and robot systems

PSO, flexible loading and unloading for customised pallets

PSU, highly popular system for carriage or belt pallet loading

All are fundamentally designed to fill - or unfill - a tray with small components. The tray is then indexed down the stack and a new tray presented, a process that is smooth andreliable. Most applications require bespoketray designs and gripper technology but we can also supply a wide range of standardaccessories to optimise the handlingprocess.

PCS products perform well and look good. So when specifying components for its tribology test equipment and laboratory instruments, the company needs to satisfy both performance and appearance criteria. And for two of its popular models this need is ably met by our Werner domiLINE linear motion system. The PCS Mini Traction Machine is a flexible general purpose instrument for measuring the frictional properties of lubricated and unlubricated contacts under a wide range of rolling and sliding conditions. And domiLINE is responsible for the linear motion and focus adjustment of the RGB colour camera and microscope system. domiLINE has a similar job in the company’s EHL Ultra Thin Film Measurement System. This is a computer controlled instrument for measuring the film thickness and traction coefficient of lubricants. The domiLINE assembly specified for this product focuses a spectrometer and monochrome camera.

THE BENEFITS OF REALI-SLIMAs the world’s largest manufacturer of thin-section bearings, KAYDON® sets the industry standard with its Reali-Slim range. These are characterised by their low profile, light weight, small cross-section, simplified design, long life and reduced manufacturing costs. These products are ideal for applications in aviation, aerospace, robotics, machine tools, semi-conductor manufacturing and medical equipment – indeed anywhere that needs a lighter, thinner bearing. They are available in different radial sections up to 40 inches diameter ex stock and larger on a made-to-order basis.

With increasing demand for complete linear sub-assemblies to reduce installation time, a new easyLINE linear motion system is now available. The package comprises the linear axis with toothed belt drive, stepper motor, controller, amplifier software

and clamping system. The carriage plate itself utilises four recirculating linear ball bushings to guarantee both high speed and smooth motion.

This new plug-and-play system allows for the easy programming of up to 16 positioning points and provides

stroke lengths from 100mm to 5.5 metres. Positioning speed is 830mm/sec with

repeatable accuracy to ±0.05mm.A Profibus or CAN interface is

optionally available.

have to be ultra-reliable

and ready for action at

a moment’s notice. These products are characterised by their compact nature, light weight and ease of use and a recent decision to include a Framo Morat Compacta slip-on geared motor has certainlyenhanced this reputation.

LINEARACTUATIONFOR TURBO COMPRESSORS

Howden Donkin integrally geared turbo compressors rely on the effective actuationof two sets of vanes that influence the air flow according to process performance. This is an operation that requires high forces at slow speeds and for this reason the Mini range of actuators, from Framo Morat were selectedfor the job.

OFFSHORECREDENTIALS

Selecting the right bearing for demanding

offshore applications depends on load, stiffness, speed and more critically safety factors and environmental protection. These factors combined with KAYDON®’s wealth of experience in providing slewing bearings with different coatings for harsh environments has resulted in a considerable increase in demand for these components in the growing offshore and related sectors.

SPACE-SAVING MACHINE TOOL BEARING

For very high volume production the Curtis VECTOR machining centre is now available with a twin spindle workhead which allows concurrent loading and grinding. It also makes a range of other applications available including in-cycle gauging. At the end of the grinding cycle the workhead drum rotates through 180° alternating the positions of the two spindles. Critical elements of this mechanism are KAYDON® thin section bearings. Curtis chose a precision class 3 KAYDON® four-point contact bearing and a radial contact bearing for this application. This is a classic combination selected by designers seeking dependable performance. Pre-load on the bearings is factory-set, minimising assembly time and assuring its consistency. The KAYDON® four-point contact bearing can accept a combination of radial, thrust and moment loads. This is thanks to the unusual

“We needed a precise, low friction bearing that occupied minimum space but was still stiff. R. A. Rodriguez fully understood what we needed to achieve and have supplied a quality product that is working well in the field. The KAYDON® bearing was ideal and gives us accuracy better than 1 micron.”

Rick Curtis, Chairman of Curtis Machine Tools

geometry of the ball grooves that creates a ‘gothic arch’ configuration making it possible for two grooves to contact the ball at four points. High thrust and moment capacity is obtained in a four-point contact ball bearing by its deep raceway grooves. These allow high initial contact angles between the balls and raceways and increase the thrust and moment capacity. The deep grooves also accommodate the contact angle increase which results from ring stretchand ball deflection under load.

SMALLERMODULE GEARSOur KHK range of metric gears is already considered to be one of the most comprehensive with 80 standard gear products and more than 3,500 individual items. KHK has however found room for even more variation. Its product programme has recently been boosted by 570 configurations of fine pitch gears. Now available ex-stock are 0.5 and 0.8 modules gears in the most popular sizes, all are manufactured to ISO/JIS gear standard. The company’s continued high investment in its manufacturing techniques ensures these products are of consistently high quality as well as being competitively priced. The KHK ranges that are extended by the smaller module gear additions are spur gears, racks, pinions and worm gears.

FLEXIBLE HELPINGHAND

The recent introduction of the Universal Robot into the production process of a Danish engineering company has allowed better use of manpower and significantly increased production capacity. The robot’s ability to serve a variety of automation tasks is particularly important to Linatex as it provides a specialised

manufacturing service that involves small production runs. Linatex processes engineering plastics and rubber for a wide range of industrial sectors. Its products are found in everything from artificial hips to aeroplanes and wind turbines. “The operator used to feed parts piecemeal into the CNC turning centre, wait for the machine to complete its cycle, then remove the part,” explains Kenneth Midjord from Linatex. “Now the machine can operate unattended until the store of plastic parts is empty. The robot really is a helping hand.” He continues, “It is an

advanced robot, yet extremely simple. It can be easily moved around the plant to do different jobs. And although some employees were initially nervous of the new tool, its user-friendliness quickly softened their scepticism.” Although the Universal Robot has only been installed for a short time Linatex

expects the investment to pay for itself in just four months.
