2D CNC Machinery introduces the Reiden BFR 2 range of multi-axis heavy duty machines

Each of the Reiden BFR 2 series of machines has identical Y and Z-axis travels of 1,200 and 1,500 mm but X-axis bed lengths of the BFR 22, BFR 23 and BFR 24 are 2,000, 3,000 and 4,000 mm respectively. 2D CNC Machinery is able to supply a choice from three direct mounted spindles depending on the type of components the machine range is likely to produce and the need to optimise production cycles. These range from a heavy duty 45 kW, 5,000 revs/min unit delivering 1,576 Nm of torque and either 6,000 or 7,000 revs/min units powered by 42 kW drive but still able to deliver a torque of 1,135 Nm and a high speed 15,000 revs/min unit with 310Nm of torque. Spindle taper is ISO 50 as standard with an optional HSK 100 also available. There are also three types of table that can be specified with a 1,000 mm square as standard. CNC rotary units are available between 1,000 and 1,700 mm diameter and combination single plane and integrated rotary table versions of 1,000, 1,250 or 1,600 mm diameter. The maximum rotary diameter is 1,800 mm as standard or 2,100 mm as an option. The maximum table loading on the BFR 24 is 11 tonnes. The machine base and column of the Reiden BFR 2 machine range is constructed from heavy duty cast iron with the various chambers in the corners of the column being strategically filled with polymer concrete to optimise mechanical and thermal stability. Stability is further enhanced with the positioning and construction of the saddle/column beam that carries the automatic ±180º B-axis swivel head. Electro-hydraulic compensation is employed to minimise any possible deflection of the Y-axis beam which is able to maintain a maximum deviation of ±0.010 mm over a distance of 1,200 mm. The tool magazine is positioned for direct change via 2-axis movement under Heidenhain iTNC 530 or Siemens 840 control. There are 64 positions as standard but options up to 240 pockets can be specified for tools up to 250 mm diameter by 600 mm in length. According to the type of work being machined, the control panel position at the front of the machine can be moved and tilted along a linear rail. A second integrated control can optionally be installed at the side of the machine. Wide opening double doors facilitate crane access. The gap on the smallest BFR 22 is 2.1 m. This increases to 4.1 m on the largest BFR 24. A separate sliding door gives additional access to the rear working area of the machine. A two-pallet system is available with either 1,400 by 1,200 mm or 1,700 by 1,200 mm pallets and each pallet is able to support loads up to 4 tonnes. Pallets are positioned using four zero-point clamping to achieve a repeatability of ±0.01 mm. A linear storage system is also available.
