Mill-turn centre has 10kW of milling
power
As well as having two Y-axis turrets, a CNC mill-turn centre to be shown at MACH 2008, offers 10kW of milling power on every tool station for milling bar, billets or blanks.
The Nakamura-Tome WY-250 CNC mill-turn centre will be launched in the UK at the MACH 2008 exhibition by Turning Technologies, part of the Engineering Technology Group The WY-250 provides highly productive machining of complex parts in one hit from bar, billet or blank, using two 'Super Mill' Y-axis turrets with 10kW of milling power available on every tool station

Adding mill-turn value is key to success
Specialising in very high-precision components, a subcontractor says adding value is the key to success, which is why it has invested in a CNC mill-turning centre.
Compact lathe gives maximum turning productivity
Whether it is shaft work, bar work or chuck work, the key to a compact, twin-spindle CNC lathe's productivity is its one-hit machining capacity in an extremely compact space.
Turning Technologies said that the WY-250 offers the reliability and capability required for high-volume 'lights-out production', tand also has the flexibility and versatility required for varied small and medium batch manufacturing.
* Heavy machining - each of the two Super Mill Y-axis turrets can hold up to 24 driven tools and is specially designed to accommodate the heat generated during heavy machining, Nakamura Tome has used larger gears, rigid drives, a large diameter drive shaft and oil mist cooling.
As with all of Nakamura's larger machines, the WY-250 also features box-type slide-ways on all axes, said Turning Technologies.

Achieving productive 'one-hit' machining
Twin-spindle twin-turret CNC lathe fitted with a robot part-loading system has transformed a general subcontractor into a world-leading brand in the mountain bike aftermarket.
Typically, the WY-250 could produce a complex aerospace component in one hit from stainless bar combining the heavy milling of features such as cross-bores and fine details such as oil ways, to the highest levels of accuracy.
With 10kW of power available on any tool and milling speeds of up to 6000 rev/min, the two turrets can work on either spindle individually or simultaneously to achieve high rates of metal removal.
The collet size on the driven tooling is AR32 and the maximum face cutter size is 80mm diameter.
Turning Technologies told manufacturingtalk.com that the WY-250 has been built to the highest Nakamura standards.
It features heavy duty box-way construction, hand scraped for micron accuracy, with temperature control to all major machine elements.
* CNC and probing - the WY-250 is fitted with Fanuc 31i-A control and incorporates as standard software that can reduce the number of fixtures required, cut setup time and avoid crashes.
'Nakamura Navigator' is a material recognition function that uses a piece of plain bar to probe for the component location and orientation.
As soon as the probe touches the component the machine senses the torque variation and determines the position of the component.
This means that the machine can accommodate billets of varying lengths and automatically set up non-round castings, forgings or extrusions.
Thus removing the requirement and cost of a turret mounted touch probe A similar method is used to detect and avoid potential crashes, caused by human error.
With 'Nakamura Air Bag' the servo drive detects the overload and reverses the axis in less than eight milliseconds.
