HIGH PRECISION MACHINING T
Sophisticated solutions from Hidelius for efficient and accurate machining of components in diverse industry sectors is now available in the UK through YMT Technologies
he Hedelius range of high precision machining centres is now available
from exclusive UK and Eire agent YMT Technologies. Renowned throughout Europe for precision and reliability in every industrial engineering sector, each CNC machine tool is produced in-house and completely orientated toward the requirements of the customer. Hedelius provides sophisticated solutions for efficient and accurate machining of components in many industry sectors, specifically aerospace, mould and die and motorsport. The high performance vertical spindle moving column product range covers 3-, 4- and 5-axis machining in pendulum and combination designs. The semi-gantry design with heavy- duty overhead roller guides on the Y-axis is designed for vertical machining. The short overhang and solid machine bed are said to guarantee perfect milling results. The fixed grey cast iron table is suitable for precise clamping of large and heavy workpieces. The chips fall from the machine table directly into the chip conveyor below. Designed for easy workpiece loading/unloading and ease of setting up and control, every detail is geared toward the efficient production of small batches or one-off components. With a large X-axis traversing range
loading and unloading of workpieces in parallel to machining cycle in pendulum operation means optimum use of the machine’s capacity. This increases the machine’s output level so that cost- effective medium to large batch production is possible. Direct NC travel measurement systems
with optical scanning, digital drives and stick-slip-free recirculating roller guides work in all linear axes of Hedelius machining centres. Powerful integral Celox motor spindles offering up to 24,000 rpm are efficient and thermally stable for increased precision. A hydro- mechanical tool clamping system with HSK 40 or 50 tapers is said to guarantee maximum system stiffness and true running quality even under extreme conditions. Fluid cooled direct drives are used for the rotary and swivel axes of the 5-axis machining centres of the RS 505, RS 605 and RS 805 (RotaSwing) Kombi range. These torque motors work without mechanical transmission elements and are virtually wear-free. Simultaneous

5-axis machining is a standard feature and these drives position the workpiece dynamically and noiselessly in any programmed angular position. All machining centres of the RotaSwing
range provide a combination of fixed machine table and rotary/tilt table unit. Designed for 6-sided complete machining, it is possible to produce even the most complex, cubic components on the rotary/tilt table units with no more than two set-ups. Tiltenta T7 machines cope with all the tasks encountered during machining. The generous workspace with an infinitely pivoting main spindle enables 3- or 4-sided face machining of long workpieces while precise 5-sided machining in pendulum operation is possible with the integrated NC indexing table and a workspace divider plate. Its design opens up new applications in the processing of single items and series. Whether end machining of long work pieces or 5-sided complete machining with integrated NC rotary table, the T7 crossover concept solves many processing tasks in mechanical engineering, tool making and vehicle production. The combination of an infinitely adjustable main spindle and long machine table with integrated NC rotary table allows the mixed production of large workpieces and precise 5-axis machining in one machine. As the smallest in the range the T7 1600 features a compact footprint and suitable for single-part and small batch production of machinery and tool making. The large machine table allows 5-axis machining of

workpieces with a swing diameter up to 1100 mm and maximum of 1200 kg clamped weight; machining of workpieces up to 1600 mm long is possible. “With every machine tool used to produce aerospace components, mould and die element or motorsport components capacity is a consideration,” explains company director Howard Mancey. “The 3-axis machines from Hedelius offer X-axis ranges of 1,800 up to 6,500 mm and Y-axis from 510 to 1,250 mm; spindle speeds go from 4,500 rpm up to 24,000 rpm with hybrid bearing spindle motors offering power up to 60 kW. The 5-axis machines feature virtually wear-free direct drive rotary and tilting tables with diameters from 420 up to 1,000 mm.” Control options include the Heidenhain
iTNC530 and Siemens 840D. A recent development from Hedelius to support extended machining operations and ‘lights out’ production is the Skyloader range of pallet systems which are fitted to the RS range of Kombi machines. These offer a capacity range of up to 41 pallets with additional tool storage of up to 190 tools, keeping set-up times to a minimum. Setting the benchmark in automation, loading and unloading of the tools and pallets is fast and easy thanks to the ergonomically designed and operator-friendly pallet set-up area.
