machining
Described as being 'ultra fast, a vertical machining centre offers an optimal balance between high speed machining performance, rigidity and accuracy.
YMT Technologies in Yeovil, UK has introduced the YCM NSV102A ultra fast vertical machining centre (VMC) designed to meet high speed machining needs It features a powerful 22kW IDD spindle design, which runs through ceramic angular contact bearings to provide superb axial and radial cutting rigidity at up to 12,000 rev/min

Additional functionality is available with the new Goodway GLS series of CNC turning centres from UK agent YMT Technologies
CNC lathe rigidity increased by 40%
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.
Combined with roller-type linear guideways and a heavy-duty frame, the NSV102A is ideal for work that requires high chip removal rates.
Equipped with oversized linear bearings on all guideways, the NSV102A offers an optimal balance between machining performance, rigidity and accuracy.
The NSV102A has rapid feedrates of 48m/min in all three axes and axial acceleration up to 1G (10m/s2).

Five-axis vertical machining centre from YMT technologies has an extended Z-axis and a swarf system that ensures removal of swarf without manual intervention.
Vertical machining centre is more precise
For precise machining of larger components, YMT Technologies has introduced a powerful vertical machining centre, which has its spindle within a symmetrical headstock that avoids thermal deformation.
5-axis vertical machining centre has large Z-axis
Machine tool builder has invested over 1000 man-hours in developing a high specification, 5-axis continuous path operating, 22.5kW, 700mm X-axis vertical machining centre with a generous Z-axis.
The heavily ribbed cast body structure has been designed using the latest finite element analysis software to absorb cutting forces and reduce vibration.
Larger than standard spans are used on the NSK roller-type guideways to ensure stability, with the Y-axis bearings set 850mm apart and the X-axis using six bearing truck to increase the workpiece load on the table to 1000kg.
Generous axis travels are provided with 600mm in Z- and Y-axis, while the X-axis is denoted by the machine identifying number, at 1020mm.
The worktable is 1120 by 650mm and is able to accommodate very heavy parts.
For the efficient evacuation of the large volume of chips that the NSV102A can generate the machine is equipped with a very effective swarf management system.
Dual screw-type chip augers are fitted one each side of the Y-axis, which feed the chips into a slatted-type swarf conveyor.
This can be specified by the customer to exit to the right- or left-hand side of the machine.
* Exceptional surface finish - the Isolated Direct Drive (IDD) 22kW spindle design provides low spindle vibration and optimal heat isolation, resulting in an exceptional surface finish.
It also maximises spindle and cutting tool life under hard milling conditions.
A spindle chiller and oil-air mist lubrication are fitted as standard for extended operation up to 12,000 rev/min (or 15,000 rev/min as an option).
Surface finish is further aided by the use of a BBT40 spindle taper for rigid face and taper contact.
Productive machining is supported by a high speed 30-station automatic tool changer (ATC) serviced by a swing-arm mechanism that changes tools up to 125mm diameter by 300mm long in just 2.5s.
An optional 48-station ATC is also available for increased flexibility and extended operation with sister tooling.
Through tool coolant at up to 20 bar also comes as standard.
Company director, Howard Mancey, said to manufacturingtalk: "In terms of accuracy and surface finish, the NSV102A is one of the best machines currently on the market.
It has generous travels and offers a 1000kg load on the worktable that allows either large parts to be single loaded or the multiple loading of smaller components.
And, the spindle is fast and powerful enough to machine a wide range of materials".
He added: "We offer the NSV102A with the high performance Heidenhain iTNC 530 as standard.
This controller comes with the innovative smarT.NC software which has a number of functions that improve the machine operation and safety.
The major benefits come from Dynamic Collision Monitoring (DCM) which helps prevent damage to the machine and workpiece, and Adaptive Feed Control (AFC) which optimises the contouring feed rate depending on the performance of the tool spindle and other process data".
With the Heidenhain controller, the YCM NSV102A has been very well received in the mould and toolmaking markets, said YMT.
Toolmakers require intricately detailed contours with high quality surface finishes.
In this niche market sector most of the key companies know one another very well, and sales based upon recommendations have been seen by YMT.
Mancey concluded: "The nature of the mould and toolmaking markets satisfied successfully by the YCM NSV102A - complex profiles and difficult to machine materials - are also present in the aerospace and automotive sectors.
It really is a complete machining package, the only options are a 4th axis, which is preconfigured in the CNC system, and tool and workpiece probing.".
