The latest Goodway 26kW CNC turning centres have a low centre of gravity on the 30 deg slant bed design that gives a rigid foundation for the headstock, turret and sub-spindle.
Yeovil, UK-based YMT Technologies, said that the Goodway GS-2000 Series of CNC turning centres' major structural components have been combined into one solid platform The platform gives a low centre of gravity on the machines' 30 deg slant bed design.
The design provides a rigid foundation for the headstock, turret and sub-spindle.
Finite Element Methods (FEM) have been used for optimal positioning of the reinforcing ribs, which are cast directly into the FC35-Meehanite one-piece cast iron bed structure.
This increases mechanical rigidity by more than 40%, allowing the GS-2000 Series to perform heavy-duty turning while maintaining high precision accuracy for extended period.
Extra wide hardened and ground box ways are directly formed onto the machine bed during the casting process.
They are precision machined and widely spaced to provide the rigidity needed for interrupted turning applications.
This rigidity also significantly increases tool life, said YMT.
The GS-2600YS turning centre features the following.
* A high precision 26kW built-in spindle motor, providing 40-4000 rev/min with full C-axis control.
* A 15kW sub-spindle provides a speed range of 60-6000 rev/min.
* The X- and Z-axis rapid feeds are 30m/min and travels are 280mm and 800mm respectively.
* A 100 mm Y-axis (+/-50mm over the centreline) on the 12-station tooling turret allows milling, drilling and tapping operations to be carried out on even the most complex components.
* A Hydrafeed bar feed unit.
"Compared to other similarly specified and capable turning centres, we offer a cost saving of around 35%," said YMT company director, Howard Mancey.
YMT told manufacturingtalk that with a 10in main chuck and a 6in chuck fitted to the sub-spindle, and 65mm diameter bar capacity, the GS-2600YS provides exceptional turning possibilities.
It has the ability to automatically transfer parts from the main to the sub-spindle.
Its live tooling turret carries milling, drilling and tapping tools allowing complex prismatic machining to be performed.
An integrated 5.5kW heavy-duty driven tool motor on the turret can accept ER40 collets and offers cutting speeds of 60-6000 rev/min.
YMT is also able to provide the Algra range of high precision driven tooling, which increases the tooling available for turning and milling operation for maximum productivity.
Using twin tooling units with front and back end working, the 12-station turret can potentially be expanded to hold 48 tools.
This productivity is supported by the tooling turret itself with has an integrated servo motor achieving a station-to-station indexing time of just 0.2s.
* CNC system - the control for the turning centre is the Fanuc 18i-TB with CAP conversational programming to simplify data inputting.
Advanced canned cycles allow complex machining to be carried out automatically.
Alternatively, YMT offers the turning centre with the Mitsubishi 720L with its powerful NAVI LATHE conversational programming system.
Mancey, said: "The GS-2000 Series is modular and customers could specify a turning centre that precisely matches their needs.
However, the reduced investment required to purchase such a capable machine means that engineering companies can add more functionality and performance and still achieve a saving on the investment made".
Mancey concluded: "We see customer support for the transition from straightforward 2-axis turning to the multi-axis turning that is available on the Goodway GS-2600YS as crucial.
To aid our customers with this process 'leap of faith' we have employed two new applications engineers, both of which have extensive multi-axis turning experience.
We feel it is this back-up and attention to detail that makes YMT Technologies stand out.".
