Nakamura-Tome has now added the JX-200 multi-tasking mill/turn centre to its line-up. Launched in the UK by the
Engineering Technology Group (ETG), the JX-200 features Nakamura’s new NT Smart Cube — the world’s shortest tool spindle in its class which provides a compact footprint, spacious work area and unrivalled kinematics which significantly improve machining performance.
Nakamura has recognised the increased need of industry to manufacture smaller batch sizes with higher flexibility. With customers wanting ‘more flexible machining’ and ‘higher part production’ rates with a single machine, which is where the JX-200 comes into its own. It can accommodate a larger number of tools and this delivers unrivalled flexibility for handling multiple types of low-quantity production.
The JX-220 is a twin-spindle machine with an upper tool spindle that swivels +/-95deg to provide exceptional flexibility. This unit has an impressive 15/11kW power output and a 12,000rev/min spindle with an 18,000rev/min spindle as an option. Moreover, the upper tool spindle has an 80-position tool carousel as standard with 40 or 120 tools as optional extras.
On the lower tooling turret, as standard, is milling capability and also Y-axis machining. The lower turret provides a 6,000rev/min milling spindle with 8,000rev/min optional and both upper and lower milling capability is extremely rigid and robust for heavy duty material-removal applications.
Simultaneous machiningIn combination with the upper tool spindle and the lower turret, the JX-200 is ideal for a multitude of different machining methods such as simultaneous machining with both left and right spindles, engaging both upper and lower tool positions simultaneously, and even machining with centre support mounted on the lower turret. With the facility for operations such as turning, milling, drilling and gear cutting, this ‘all in one’ machine will appeal to manufacturers in a variety of industry sectors.
This flexibility is underpinned by a new heavy-duty column structure that has now been introduced to the JX-200. To create the most stable and robust platform for machining all material and component types, the new design has an optimised centre of gravity design that gives unparalleled strength and stability against loads from any direction.
The machine has a 65mm bar capacity with 51 and 80mm diameter options. The 65mm machine has a maximum turning diameter of 325/255mm with a maximum turning length of 1,058mm. All this is crammed into a compact floor area of only 2.9 x 5.2m.
