The RX12 which is available in the UK through 2D CNC Machinery, incorporates Reiden’s patented double-drive spindle technology (DDT) with the new machine developed around Hydropol, a highly rigid specialised concrete and steel composite for the bed and column that can be completely recycled.
The machine is demonstrated in cell form with a two-pallet system and has axis travels of 1,300mm in X, 1,450mm in Y, and 1,000mm in Z with rapid traverse rates of 50m/minute. In addition, the A-axis for the spindle is 0 - 90° to enable horizontal and vertical cutter positions with the 1,200mm diameter rotary table which has a swing of 1,200mm and rotates through a programmable gearless drive at up to 400rpm.
The construction of the Reiden RX12 around its Hydropol composite provides high orders of inherent stability. It absorbs vibration and has significant levels of dynamic stiffness. In producing the composite against a normal cast iron frame, 30% less primary energy is used and CO2 levels are 66% lower.
As a result of the construction, both 5-axis milling and turning operations can be integrated into a single machine setting and benefit from Reiden’s patented spindle DDT development. The spindle is able to swivel between horizontal and vertical planes within one second and the slim head design has pneumatic clamping to hold position when used for turning cycles in conjunction with the direct drive rotary table. This table has automatic imbalance detection and counterweights to minimise vibration.
The DDT spindle concept uses two separate motors built into the same housing which are connected via a bevel gear drive coupling arrangement. According to the machine program, hydraulic power is used to engage or disengage the higher torque system which also enables the unused drive to freewheel.
Control is via either Heidenhain TNC 640 or Siemens 840D sI. A two-pallet system is being exhibited but machines can be supplied with options of five pallets each 1,200mm by 1,000mm or a linear storage system.
