VERTICAL LATHE FOR DEMANDING APPLICATIONS

 May 2012   News, Presse  

EMCO's VT 400 offers numerous benefits for large workpieces

The new EMCO Vertical 400 extends the capacity of the company’s successful series of vertical lathe machines. The Vertical 400 enables users to alternate lathe work with additional drilling and milling. It fits chuck parts with up to 400 mm clamping diameters and 450 mm swing diameters, 200 mm length and 40 kg weight. Combined with its compact design, its small footprint and automated operation, it offers a cutting edge solution in its class.

The automation concept enables customer-specific solutions. Since the pick-up system removes the need for additional loading systems for workpieces, machine linkage and technical adaptation are easily made to fit any customer’s individual needs. The main spindle carries out the movements in the X-and Z-axes, and the workpiece arrangement ensures a free chip fall. High user requirements are fulfilled by the welded steel construction of the rigid vibration absorbing machine bed. This also applies to the headstock thermo-symmetrical construction. High rigidity allows large distances between the guide tracks of the slide system and the size 55/45 linear carriage.

The digitally controlled synchronous motor of the main spindle provides a drive power of maximum 36 kW, a speed of 4000 rpm and a torque of 600 Nm, ideal for high-duty works. Direct driven ball screw spindles from Ø 40 mm with backlash and maintenance-free claw couplings enable speeds up to 45 m / min. The travel distances are X = 960, Z = 400 and Y = +/- 90 mm. In case of Z-axis power failure, mechanical weight compensation prevents the Z-axis from falling.

Both the inner and the outer machine casing are designed for low maintenance. For the stainless steel covers and wipers do not require telescopes; guides and seals are protected from flying chips. The completely sealed casing allows an economical and ecological suction system since the machine door stays closed even when picking up a new workpiece. And all these functions of vertical lathe and complete processing machine lay in a compact 6.2 m2 footprint.

With the VT 400, the user can choose two versions and additional options. In addition to the basic version without Y-axis, a version with the moving turret axis and driven tools is provided offering the advantages of complete processing. Optionally, a multi-function panel can be selected, as well as stationary or driven tools. This also applies to long drill and perforating tools. Finally, the user can choose to implement the VT 400 linear optical measurement systems, process monitoring and electronic analysis.


EMCOTURN E45: WITH NEW INTERNAL AND EXTERNAL “VALUES”

 September 2013   News, Presse  

Y-axis, Z stroke of 510 mm, automatic tailstock and a new design – the “enhanced“ version of the EMCOTURN E45.

Driven tools, powerful digital drives and a fully-equipped Siemens or Fanuc control system - customers are left wanting for nothing, including a reasonable price. That is what "Design to Cost" means - offering customers the maximum benefit at a minimum cost.
HALLEIN - All components affecting the performance, precision and product life expectancy of the machines are optimized while simultaneously focusing on the essential functions for the customer. That's what "Design to Cost" means. And the EMCOTURN E45 meets this EMCO requirement in full. 
The E45 – for manufacturing medium-sized workpieces with top European technology
With a speed of up to 6300 rpm, a main spindle drive power of 13 kW and a tool turret with 12 VDI 30 stations, 6 of which are driven, this compact universal lathe with a bar capacity of 45 respectively 51 mm is ideal for dynamic machining of workpieces such as fittings, plungers, piston rods or connecting shafts.
Uncompromising quality right down to the last detail
The machines are developed and produced exclusively in Central Europe, true to the EMCO’s "Made in the Heart of Europe" commitment, in co-operation with European brand-name manufacturers who meet the highest standards regarding quality, productivity and efficiency.
The technology in detail 
Despite its comprehensive equipment, the EMCOTURN E45 takes up very little space: a very solid cast machine base, a thermosymmetric headstock with high-precision spindle bearings, preloaded roller guideways in all axes and a rapid-indexing SAUTER tool turret ensure maximum dynamics and precision. Customers can choose between a Sinumerik 828D and Fanuc 0iTD control system – including dialogue programming with ShopTurn or ManualGuide i.
The Y axis is integrated in the standard build of the machine. This guarantees maximum stability as well as the highest degree of precision of all finished parts. The extremely wide guide distances of the Y axis ensure stable turning and give the user even more opportunities for unilateral complete machining.  
Tailored automation
A swing loader is included for automatic loading and feeding out of the machined parts. This extremely compact and integrated loader is controlled via the machine control. The exceptional combination of a swivel movement and a linear movement, driven by servomotors, guarantees simple and fast setup. As a result, preformed raw parts can also be inserted position-oriented into the clamping device. After machining has been completed the finished parts are transported out of the machine via the parts catcher.
For rational machining the bar loader package with the short rod loader EMCO COMPACT LOAD, parts catcher, alarm lamp and interface or the EMCO TOP LOAD 8 42 or 8 50 for the fully automatic loading of bar material up to a diameter range of 8 to 50 mm and a length of up to 3.2 meters are available. For more information about the new Emcoturn E45 click here >>


HYPERTURN 65 POWERMILL – FOR GREATER PRODUCTIVITY IN COMPLETE MACHINING OPERATIONS FOR COMPLEX WORKPIECES

 September 2013   News, Presse  

ore clearance, more power, more possibilities: with a spindle distance of 1300 mm, a powerful counter spindle which also allows 4 axis machining, a B axis with a direct drive for complex 5-axis simultaneous milling operations, an additional Y axis for the lower turret, and all proven, high-quality features of the Hyperturn series, the Hyperturn 65 Powermill is a powerful addition to every machine range.

The HYPERTURN series was conceived to gain considerable increases in productivity during series production. Complex as well as costly turning, drilling, milling and gear cutting operations can be carried out in only one work process. Additional clampings and the temporary storage of parts are no longer necessary and workpiece precision is greatly improved. Total production time, fixture and personnel costs, as well as floor space requirements can be drastically reduced by choosing to work with the HYPERTURN.
With a spindle distance of 1300 mm, the Hyperturn 65 Powermill has significantly more clearance for simultaneous machining works on the main and counter spindles than comparable models. With 29 kW and 250 Nm the counter spindle now has enough power to machine the workpiece simultaneously with two tools. This "4 axis machining" is a further aspect to improve productivity. A further benefit is the milling spindle, which with 29 kW, 79 Nm and 12,000 rpm, stands for high productivity in the complete machining of complex workpieces. The B axis direct drive gives the Hyperturn 65 PM good dynamics and contour capabilities with 5 axis simultaneous machining, alongside shorter ancillary times spent changing tools. The additional Y-axis on the lower turret makes extensive milling work possible at the same time as machining with the milling spindle. 
20, 40 or 80 piece tool magazines with HSK T63 give the user more possibilities for complete machining operations of complex workpieces, with simultaneously low set-up times for individual parts manufacturing and high stability for turning and milling works. The frontal arrangement is easy to set up and ergonomic.
As an alternative to the VDI30 or VDI40 12 position tool turret, EMCO offers a new generation of turret with BMT interface and direct drive. Higher stability and precision, and performance data similar to a milling machine, enable the complete machining of turning/milling workpieces.
The machine versions with a milling spindle and turret including milling drive (SMBY/SMBY2) have a cross slide underneath with a 12 position radial turret for 12 driven tools working up to speeds of 5000 rpm.
The automatic bar machining and/or delivery of unit loads via a robot solution or the EMCO gantry loader offer excellent potential for increased efficiency in automation. 
In addition to mechanical and electrical performance values, control systems and software are increasingly determining the productive efficiency of machine tools. Emco has therefore fitted the Hyperturn 65 with the SINUMERIK 840D sl control unit from Siemens. The new user interface enables an intuitive and significantly easier programming of the machine.
Utilizing the machine to its full capacity as far as possible is a crucial aspect for increasing productivity - the EMCO CPS Pilot can generate time and cost savings during machining as the software enables customers to plan, program, simulate, and optimize production runs on their PCs using a 3D model of the machine. The combination of the HYPERTURN with the new EMCO CPS Pilot results in extremely positive multiplier effects: the perfect interplay between CPS Pilot and the HYPERTURN means significant cost and time savings can be achieved (see also the press release on EMCO CPS Pilot). 
The HYPERTURN 65 Powermill is particularly interesting for the serial production of workpieces, for example in the automotive industry, the fields of mechanical engineering and materials handling, but also for the aircraft industry.


VERTICAL DUO FOR DEMANDING APPLICATIONS

 September 2013   News, Presse  

VT 160 and VT 250 with right and left machine as a Duo cellThe machine concept of vertical pick-up machines as a modular system meets manufacturing companies' requirements for more quality, while simultaneously maintaining high flexibility and reducing cost. The right-hand and left-hand versions of the VT 160 and VT 250, and three basic conveyor versions - in oval, meander, and crossover meander designs - give operators a complete machining solution for workpieces with diameters of up to 250 mm, a workpiece weight of 8 kg, and a workpiece height of 150 mm with 30 workpieces (oval) or 50 workpieces (meander). The integration of a cross-over allows the use of different pallets or different workpieces.

The VT 160 and VT 250 "Duo" solutions give the user decisive system and technology advantages. Both final machining of a workpiece (2 face machining with the OP 10 and OP 20) and the production of two different workpieces is possible (part A on machine 1, part B on machine 2). Thus the automation solution supports a variety of customer-specific solutions - with or without a workpiece carrier (or pallet), the implementation as a Duo cell is compact and space-saving, and it offers unrestricted access for charging and discharging.
Multiple machine operation and short set-up and retooling times reduce waits. Optimised production processes and short chip to chip times create ideal conditions for complete machining with high quality and efficiency. 
The machines both fulfil stringent user requirements - e.g., thanks to the steel-welded construction of the rigid, vibration-damping machine bed. This also applies to the thermo-symmetrical construction of the headstock. Excellent rigidity is also ensured by the large distances between the guideways of the carriage system and the size 45 linear carriage. 
The digitally controlled synchronous motor on main spindle offers sufficient reserves, even for heavy-duty machining, with maximum outputs of 29 (VT 250) and 21 (VT 160) kW power, speeds of 5000 rpm or 7000 rpm and 280/150 Nm of torque. Directly driven ball screws of Ø 40 mm with lash and maintenance free claw couplings achieve speeds up to 60 m/min. 
The traverse strokes for the VT 160 are X = 620, Y =  65 mm, Z = 310 mm, and for the VT 250 520 /  90 / 310 mm. To prevent the Z axis dropping in case of a power failure, it features mechanical weight compensation. 
Both the inner and the outer machine panels are designed for low maintenance. The stainless steel covers and strippers do without telescopes; guideways and seals are protected against flying swarf. The fully enclosed fairing allow for economically and ecologically meaningful extraction, as the machine door stays closed even when picking up the workpiece. And for all of these functions, the Vertical Duo VT 160 and VT 250 in the meander version with a crossover and turner need a footprint of just 21 m2. 
With the VT 250 and 160, the user can opt for different versions and additional options - see the version descriptions for details. Beyond the basic version without a Y-axis, the version with the moving turret axis and driven tools leverages the benefits of complete machining. A multi-function platen is optionally available. It can accommodate additional fixed or driven tools. This also applies to long drills and piercing tools. Also optionally, operators can add a linear measuring system, process monitoring and electronic evaluation to their VT 250/160.

COMPLETE PRODUCTION IN A SINGLE CLAMPING CYCLE.

 March 2014     

The specialists at Weico Mechanical and Metal Engineering in Feldthurns, South Tyrol, have seen how the MAXXMILL 500 has met and exceeded this expectation. A shorter production time and machining in a single clamping cycle result in greater efficiency and precision.

Complete production in a single clamping cycle.

Flexibility with lots of options
Based on their intensive use of the machine in practise up to
now, the two founders of the company feel fully vindicated in
their choice. „It has enhanced our flexibility, both in that we
can now choose from a wider range of cutting tools and can
perform machining over five axes in a single clamping cycle.
This machine has enabled us to achieve the short lead-times
that our customers expect,“ points out Hubert Weissteiner, the
engineer. And Christof, the „economist“, also highlights the
competitive costs of the finished parts.
Efficiency for SMEs
MAXXMILL 500 users can manufacture complete workpieces with
edge lengths of 500 x 500 x 475 mm along five axes, efficiently
and with precision, and in a single clamping cycle. Machining on
five sides without having to reclamp brings about financial and
quality-related advantages for small and medium-sized enterprises.
Small or medium-batch series, ideally between 15 and 300
units, can be manufactured efficiently and to a high standard of
quality. The tool magazine holds 30 tool stations ready for use.
