Products Production equipment Induction heaters with new safety benefits
Schaeffler has improved its Heater range of FAG induction heaters to include several technical innovations, which not only improve the safety and reliability of the devices, but also maximise plant and machine availability for end users. Schaeffler’s heater range includes seven induction heater models, which are suitable for the mounting of bearings – or other circular steel components such as gears, couplings, pulleys and bushings – with a minimum bore diameter of 10mm, up to bearings with outside diam- eters of 1,500mm, with a maximum weight of 1,200kg. High machine availability depends on the quality and
reliability of individual machine components. Prior to mounting, workpieces such as bearings must therefore be heated uniformly. If heat output is too high, this can cause temperature differences between the inside and outside of the workpiece, which in turn, can lead to cracks or distor-
tions in the material. In order to prevent this, Schaeffler’s new redesigned FAG induction heaters are equipped with various new features, including temperature-time (ramp) controls, which prevent overheating of the workpiece. Schaeffler believes no other induction heater currently available is equipped with these controls. An automatic overheating switch-off function is provid- ed, ensuring that the heater’s induction coil never over- heats, which reduces the risk of damage (stress fractures or cracks) to the workpiece. Another safety feature provided is an infrared remote
controller which is useful with regard to health & safety regulations which stipulate an operator must stand at a safe distance from the heater during the heating process. All FAG induction heaters are fitted with a new cooling element/heat sink, which dissipates heat inside the heater
more effectively, providing further added protection against overheating.
For users who may be unsure of the size of induction heater they require, Schaeffler’s FAG Heating Manager software ensures that the correct selection is made quickly and easily. Schaeffler
www.schaeffler.com Steel machining drill triples productivity
Designed for efficient and cost-effective machining of steel and cast iron, the new MEGA-Speed-Drill from MAPAL, a supplier of cutting tools for precision machining applications, enables users to achieve up to three times the productivity of conventional drills without any significant increase in tool costs. The new drills are equally suitable for wet and dry machining, and provide dependable results in
even the most demanding of applications. The new cutting edge geometry featured by MEGA-Speed- Drills, which has an unequal cutting pitch and three guide chamfers, virtually eliminates vibration during machining and also reduces friction. In addi- tion, the drills have highly polished flutes that guar- antee optimal chip flow.
The drills are able to produce bores at more than twice the cutting speed and up to 30 per cent higher feed rate than conventional drills. This allows pro- duction to be reduced by up to 50 per cent compared with the use of standard carbide drills. MAPAL’s new high-performance MEGA-Speed- Drills are offered in standard versions with diame. MAPAL is also able to apply the innovative technolo- gies used in MEGA-Speed-Drills to custom tools. MAPAL

12 Welding innovation Welding wire feeder for robots
ESAB, the welding and cutting technologies specialist, has launched the Aristo RoboFeed 3004HW welding wire feeder that is designed for mounting on hollow-wrist robots. The compact and lightweight feeder does not hinder flip over motions in robots of this type, and the low weight does not restrict the high accelera- tions required for fast cycle times. The feeder is compatible with
ESAB’s SAT (Swift Arc Transfer) technology for high deposition rates. This means the ultimate welding productivity package can be sourced from ESAB, compris- ing an Aristo welding power source, Aristo U82 handheld con- troller and Aristo RoboFeed unit that are all SAT compatible, plus endless MarathonPac bulk drums of high-performance welding wire. Together these products deliver
high productivity, low downtime for maintenance, and zero stop- page time for wire spool changes. Features which help to min- imise downtime include wear parts – such as feed rollers and nozzles – that can be changed in approximately three minutes with no need for tools, and a design that facilitates the exchange of the feed unit, con- troller or cables in just 15 min- utes.

Mobile filter for fume extraction
Flextraction, supplier and manufacturer of Local Exhaust Ventilation (LEV) products for dust and fume extraction, is offering TEKA’s BGIA approved Strongmaster mobile cartridge filter for industrial fume extraction. The Strongmaster comes equipped with a separator, durable, de-dustable, large- surface filter cartridge and PTFE lami- nate. The device was exhibited by Flextraction in the AWD Welding World Village at MACH 2012 last month. The filter cartridge is de-dustable for a long life and reduced operating costs. It stays in the unit during de-dusting, preventing dust from entering the work- room and the unit comes supplied with a visual and acoustic filter monitor, sealing face lifter, hour-meter, direction display, cable reel and castors with brakes. Strongmaster is BGIA-approved for every type of TEKA suction arm and is ready assembled. Features of Strongmaster include 3,000m3/h fan capacity, low 75 dB(A) noise level, maintenance doors for easy access to filter cartridge, dust col- lector and fan. Strongmaster collects dust and fumes by suction arm or suction hose and lead into the filter unit. A large surface spark protection serves as pre-separator and distributes dust particles on the whole filter surface. Flextraction T: 01664 410641
