Since hardness is the same as resistance to wear, natural diamond (ND) wears in certain directions. When drawing wire in tools using ND, carbon atom layers are stripped o the surface of the diamond in the “softer” directions. The cylindrical part of the drawing die geometry becomes oval while the atomic surface stays solid and smooth. In contrast, the random orientation of diamond grains in a PCD die suggest the material’s hardness to be isotropic. The paradox is that wear of a PCD is higher by weight, but its service life is longer.

reels up to 50 tons and with a diameter of 6m. The advantages of having a high- performance lithium battery, rather than a lead battery, are related to the duration of its charge and lifecycle. The lithium battery is also completely free of polluting substances, and therefore is safer for the operator and the environment. In addition to being moved in a straight line, a reel might need to change direction without requiring the worker to use brute force in order to rotate it. Reel Turner is an accessory specially designed within the Moviroll range for rotating and reorienting anged reels, with a load force of 8 tons. Moviroll MRE L can lift the drum onto Reel Turner, and then discharge it after rotation to the correct position. Renova Srl www.renovainnovations.com

The technical standard ISO 11228 – ‘Ergonomics – Manual handling’ – speci es the risks and the recommended limits for pushing and pulling activities carried out by an adult worker in an upright position, who applies force with both hands to move or stop an object. The standard takes into consideration a series of variables, such as strength, posture, distance travelled, characteristics of the object, individual characteristics of the operator and the work organisation, allowing evaluation of the health risks for workers deriving from manual transport. In general, manual handling of loads that represent a potential danger for workers should always be avoided. If the recommended limits are exceeded, measures should be taken to avoid performing the task manually. In the wire and cable industry, operators might need to manually move reels across the plant, if there is not enough space for forklifts or other material handling systems to move freely. Moviroll, from Renova Srl, allows the operator to e ortlessly and safely manoeuvre large or small reels on a at surface where forklifts cannot operate. Compact and handy, while also being heavy-duty, it has both forward and reverse gears, and can operate even when there is limited space between reels. With the tilting handle the operator can work alongside the load by turning the handle and pulling the load instead of thrusting it.

Because the mechanical polishing of diamond (eg supported with ultrasonic sound) can only be done using diamond powder, making this endeavour nothing but guided wear, the surface diamond grains’ points are smoothed o , but the crystalline structure remains. It is yet to be settled whether these depressions on the surface – the softer anks of the formerly single crystals – have a bene cial impact on the e ect of the lubricant, perhaps like “lubri cation pockets”. As to the choice of which material – ND or PCD – would be better suited, apart from the question of price, the following is true in practice: wire drawing dies with natural diamonds provide the best wire surface, but with higher likelihood of non-circularity; and wire drawing dies with PCD give a rougher wire surface, but longer tool life. With the achievable smoothness of PCD wire drawing dies made with MANT with a grain size of 1µm, it is possible in practice to set up multi-die drawing machines without ND wire drawing dies. The period of use of PCD MANT wire drawing dies, eg for end-dies with 0.15mm, is claimed to be around two to four times higher than that of wire drawing dies with ND.
