New Nakamura Tome NTRX-300 – the fusion of a lathe and 5 axis!
The latest innovation from Nakamura-Tome is the NTRX-300, a heavy duty multi- tasking machining centre with full 5 axis capability to offer complete component machining in a single set up.
The X and Y axis travel on the machine ensure a machining range of 250mm wide, further enhanced with the X axis having a 125mm travel below the spindle centre to extend the machining range to 250mm square.
The NTRX-300 is available from the Engineering Technology Group in Southam who are exclusive distributors for Nakamura-Tome Machine Tools in the UK and offer extensive engineering and technical support throughout the lifetime of the machine.
Features within the machining envelope include the B axis with a 225º rotation, a maximum workpiece turning length of 1150mmm and the distance between spindle centres of 1350mm.
Because of the 300’s reduced distance from the tool tip to the B-axis centre of rotation, the B axis resists cutting torgues and retains stable machining performance. The X, Y and Z axes are all highly stable, being directly mounted to their respective ball screws to ensure backlash free, high speed and smooth movement.
The NTRX-300 features a robust 18.5kW tool spindle offering 8,000rpm (12,000rpm optional). It is available with either tailstock or twin spindle configurations.
In twin spindle configuration the LH and RH spindles offer 4,500rpm with 15kW powerful motors and up to 30kW cutting power can be available for turning shaft work with the synchronised spindles. High powered motors are also available for large bar capacity versions at 22kW.
All these features in a machine mounted on a uniquely designed bed which maximises thermal stability, creates uniform loads during slide movement and features a highly rigid spindle.
From the operator standpoint, a feature of the NTRX-300 is the ergonomic operating position with the spindle centre easy to reach at 1100mm above floor height and 450mm from the door. Likewise the operating panel offers a range of vertical and lateral adjustments making it easier for the operator to work at the panel.
The machine features Nakamura’s new Smart X control interfacing with the main control based on a Fanuc 31i-B5 5 axis system. It also features a unique in-built load/unload device, a 40 tool Capto C6 ATC as standard (60, 80 and 129 capacities optional) and a standard bar capacity of 65mm with options of 71mm, 80mm and 90mm diameter. Eight or ten inch chucks can be mounted to either spindle.
