14 13 Lifting magnets Magnetic lifters are quicker, easier and safer to use than slings, chains, hooks and grabs, and do not mark the load. Onboard switching and permanent magnet technology mean installation and operation could not be easier and running costs are non-existent. Access is only required to the load's top face, allowing for more efficient storage and handling. Ultralift Plus The world's safest lifter Lifts up to 2000 (flat) 800 (round) 3 safety features: Locking switch handle mechanism Unique 'Safety Shim': pre-test any load to ensure a 3:1 safety factor Locking eye mechanism: magnet cannot be switched off while holding a load B C D A E F 3:1 SAFETY FACTOR The patented 'safety shim' allows pre-testing of the load to be lifted, irrespective of weight, material type, material thickness and surface condition.

22 21 Magnetic workholding Premier range magnetic chucks Eclipse Magnetics invented the first permanent magnet chuck in 1934 and we continue to set the benchmark for quality workholding with today's Premier Range. Premier range chucks are fully serviceable and can provide many years of service. Rectangular The all-metal top plate is extra thick to ensure maximum accuracy after frequent re-grinding Chrome plated side and end stops for packing and positioning The chucks can be partially magnetised to allow part positioning in set up Removable, ergonomically designed handles allow easy switching Supplied with clamps Custom sizes are available. Please call for details Length Width Height Pole pitch AX47/P AX510/P AXS612/P AXS614/P AXS618/P AXM824/P dimensions are reference only See page 14 for service and repair details Circular The unique top plate configuration concentrates the magnetic energy on to the face of the chuck. The chucks can be partially magnetised to aid the correct positioning of the workpiece. Grooved rings in the top plate assist in visual positioning to aid quick changeover in set up. Excellent for holding thin ring-shaped components that can be subject to radial distortion. Removable handles allow easy switching. Radial pole Radial pole configuration concentrates the entire magnetism of the chuck into the workpiece ideal for a wide range of operations from precision grinding to heavy turning. Dynamically balanced to enable use at high rpm. All metal top plate and a rugged, industrial build ensures accuracy and longevity. Through-bore (except the NR100C) allows through-flushing of coolant during machining.

24 23 Guide to magnet materials When choosing a magnet material for an application you should take the following factors in to consideration: Flux requirement of the application Maximum operating temperature Likely exposure to corrosive conditions Magnetic stability Size / weight limitations What strength/flux of magnet do you need? This table (right) shows the comparative magnetic strengths of the same volume of the four main magnet materials in terms of their maximum energy products (BHmax) in CGS or SI units and their typical pole face flux densities. Neodymium is the most powerful magnet material available. It is ideal for applications where high flux density is required or where space is at a premium. Ferrite Alnico Samarium Cobalt Neodymium Max energy product: CGS units 3.3 MGOe 5.2 MGOe 26 MGOe 35 MGOe Max energy product: SI units 26 Kj/m3 42 Kj/m3 208 Kj/m3 279 Kj/m3 Flux density 1000 gauss 1300 gauss 3500 gauss 4500 gauss What temperature will the magnet be operating in? In most applications operating temperature is not a consideration but extreme temperatures will have an effect on the magnetic performance. Each material has different temperature characteristics and these must be reviewed to ensure that the correct material is used for the application. Using the wrong material could lead to loss in magnetic performance. Ferrite Alnico Samarium Cobalt Max working temp. C Effects of sub zero temp. Large irreversible losses below 60 C Permanent losses no more than 10% expected down to 269 C Minimal losses down to 269 C Reversible effect of temp. 20 C 150 C 0.19% per degree C 0.02% per degree C 0.003% per degree C Neodymium 80* No irreversible losses down to 196 C 0.12% per degree C Other factors to consider *N35 grade only. Other grades are available up to 180 C. Corrosion Another potential cause of performance loss is a breakdown of the magnet s composition due to corrosive environmental effects. Ferrite Corrosion resistance uncoated Excellent Resistance to demagnetisation High The table shows relative corrosive resistance for each material when uncoated. As neodymium s corrosive resistance is poor it is usually sold with a protective coating, normally either nickel or zinc. External Demagnetising Fields/Magnet Stability Temperature has the greatest effect on magnet stability but high external magnetic fields can influence them. Alnico Samarium Cobalt Neodymium Fair Excellent Poor Low Very high Very high The table shows the relative demagnetising effect on each material. A world leader in magnetic technology

25 24 Magnetic field flowing across an air gap? Use a magnet with 1 pole (bar, block, disc and ring magnet) When a depth of field is required for attracting, switching or actuating across an air gap use a single pole magnet. N S Single pole operation Magnet flux crosses a gap but has a diminishing strength field. Clamping, holding or lifting? Use a magnet with 2 poles (horseshoe, button or pot magnet) Two pole or multi-pole magnets are designed for holding, clamping or lifting when in direct contact with a ferro-magnetic surface. N S 2 pole operation Magnet flux does not travel as far but is stronger. Pot magnets Both north and south pole are on one face of the magnet, similar to button and horseshoe magnets. Steel pot North pole Non-magnetic material Magnetic material South pole The magnet material is encased inside a steel pot. The pot is part of the magnetic circuit. The poles are concentric. The depth of the magnetic field is shallower than magnets with poles further apart, e.g. horseshoe magnets, but grip in intimate contact is generally superior. Max temp. of pots is lower than the magnet material used because of the different thermal expansion rates of the material and the pot. Exposure to temperatures higher than the recoended max. can cause units to come apart. Button magnet North pole South pole Horsehoe magnet Other features No stray flux as magnetism is retained in a closed circuit. Pot screens magnet material from demagnetising effects. Pot is machinable. Can be inserted into steel without adverse effects (not the case with unscreened magnets) Please note this guide provides general information only, for specific information on bespoke products or applications please contact us on +44 (0)

26 25 Glossary Coon terms used in magnetic applications Air gap Any non-magnetic gap in a magnetic circuit (i.e. the distance between magnet and ferrous object). This gap often includes other materials such as copper, brass, aluminium and paint. Effect on working temperature gradient This is the loss (reversible) in Flux per increase in degree C. Flux density Magnetic strength measured in Gauss or Tesla. The total magnetic induction over a given area in an open circuit. This value is quantified as E.M.F. (electromotive force). Flux leakage Loss of magnetic flux caused by saturation of the magnetic circuit or an air gap within the circuit. Gauss / Tesla Unit of measure of lines of magnetic flux Gauss = 1.0 Tesla. Anisotropic A magnet that has a preferred magnetic orientation i.e. magnet strength is superior in the direction of orientation. Maximum energy product (BH max) The product of magnetising force H and induction B reaches a maximum. This maximum value is called the Maximum Energy and is measured in Mega Gauss Oersted, MGO or KJ/m3 Maximum working temperature This is the maximum working temperature of the magnet material before permanent losses occur. Closed Circuit When the magnetic flux path outside the magnet is confined within the attracted material. Open circuit When the magnet is not assembled in any magnet circuit and the magnets leakage field is used. Newtons / Kilograms In this case unit of measure of lifting capacity Newton s = 1.0 Kilogram. Reversible temperature coefficient A measure of the reversible changes in flux caused by temperature. Isotropic A magnet that has no preferred magnetic orientation i.e. magnetic strength is the same in any direction. A world leader in magnetic technology
