THE MAXXTURN 45: Best Performance – Best Price

With the high-performance MAXXTURN 45 lathe, EMCO offers the perfect solution for cost-effective complete machining off the shelf, which can be used to achieve significant increases in productivity. This is ensured by highly dynamic drive systems. A pleasant side effect: the required precision and rigidity for the production of complex turned and milled parts is also guaranteed.

Hallein – The MAXXTURN family now consists of five members: the MAXXTURN 25, 45, 65, 95 and 110. While the smaller three high-performance turning centers with the counter spindle represent the perfect solution for the economical complete machining of bar and chuck parts the MAXXTURN 95 and 110 focus on the machining of shaft and flange parts. Equipped with a Y-axis, driven tools, a high-precision C-axis and very fast rapid traverse, the MAXXTURN series has everything the customer needs to produce complex turning and milling parts perfectly.

Comprehensive range of parts
Depending on the version, the MAXXTURN 45 provides the basis for the rational manufacture of precision and turned parts. The range of manufactured workpieces ranges from hydraulic / pneumatic components to machines, engine and vehicle parts to elements of medical technology or fastening and conveyor technology. Also slide and roller bearing parts and much more. can be produced.

Individual automation
A swivel loader is available for automatic loading and unloading. This extremely compact and integrated loading device is controlled by the machine control. A swivel movement and a linear movement driven with servomotors guarantee simple and quick set-up. Preformed raw parts can therefore also be inserted into the clamping devices in a position-oriented manner. ¤ After finishing, the finished parts are transported out of the machine and stored using the parts catcher.

For bar processing, EMCO offers two different loaders: the swivel loader as a universal loading device for preformed blanks of all types and the short bar loader SL1200 as the perfect solution for the automatic feeding and reloading of cut bar material.

The highlights of the MAXXTURN series
 The Y-axis is integrated in the machine structure of the entire MAXXTURN series. This guarantees maximum stability and the highest precision of all manufactured parts. The extremely wide guide distances of the Y axis ensure stable turning and give the user even more options for complete machining.

Another highlight is the compact counter spindle, which can take over workpieces in a position-oriented manner and with maximum precision for machining the rear side. A second set-up and associated downtimes are avoided. This leads to significant increases in productivity and shorter parts delivery times.

The tool turret with single-motor technology has space for 12 VDI25 tool holders. Each station can hold powered tools. A servo motor drives the driven tools or the swiveling movement. The tool holders equipped with EMCO alignment plates enable simple, repeatable insertion of the tools without time-consuming adjustment effort.

As part of the modular structure, the customer can choose between a SIEMENS (including ShopTurn dialog interface) or a FANUC (with Manual-Guide-i programming interface) control.

Technical details / The machine concept of the MAXXTURN machine bed

:
The heart of the machine is the 72 inclined bed. The very stiff and compact welded steel construction forms an extremely solid basis for manufacturing that is as precise as it is economical. The advantages of steel compared to machine casting are, on the one hand, the higher rigidity, on the other hand, the better thermal behavior of the lathes during the warm-up phase. The machine bed of the MAXXTURN 45 is filled with vibration-absorbing special material to optimally dampen the vibrations and resonances that occur during machining. The result is a perfect image and the best roundness values.

Reinforcements provide additional stiffness in heavily used areas. The MAXXTURN 45 is equipped with wear and play-free roller guides. These are supplied with the highest possible preload and screwed onto high-precision, ground contact surfaces. Perfect guiding properties without stick-slip effect guarantee the best surface quality on the finished workpiece. Covers on the guideways and additional telescopic covers made of stainless steel increase operational reliability and service life.

Main spindle
The high drive power of the spindle, combined with optimal torque curves, ensures cost-effectiveness both in steel machining and in high-speed machining of aluminum. These enable a particularly large speed range combined with extremely good concentricity. A symmetrical headstock with attached cooling fins ensures optimal thermostability. 

Tailstock
On the MAXXTURN 45 with tailstock, this is mounted on the roller guide track and can be moved automatically over a length of 510 mm. The rolling center with MK4 shaft is inserted directly into the tailstock and can be removed using a push-off wedge.

Counter
spindle On the MAXXTURN 45 S with counter spindle, the counter headstock sits on its own roller guide track and can be moved automatically over a length of 510 mm. A stroke-monitored parts ejector, flooded with coolant, ensures that the finished parts are transported away safely.

Tool carrier
The tool carrier consists of a 12-way VDI25 radial turret with single-motor technology and quick-change system. All 12 stations can hold driven tool holders. A servo motor drives the driven tools or the swiveling movement. The machine operator can influence the swivel speed at any time using the feed override switch. The turret can be used on both spindles and is interlocking with directional logic, so it always swivels over the shortest path to the next tool. The tool holders, equipped with the EMCO alignment plate and DIN 5480 coupling, enable simple, repeatable insertion of the tools without time-consuming adjustment work ¤

C-axis / main spindle (depending on the version)
The C-axis is part of the basic machine equipment. It allows the spindle to be positioned within a resolution of 0.001 °. A directly attached, non-contact rotary encoder without belt drive guarantees a precise C-axis and guarantees precise milling. In addition, the position of the main spindle can be clamped for drilling and milling operations using a spindle brake.

Y axis (depending on version)
The Y axis is integrated in the basic machine structure and set at 90 ° to the X axis. Extremely short projections are the basis for solid turning and drilling operations and milling operations without interference contour.

Feed drives
Highly dynamic three-phase drives in all linear axes with preloaded ball screws ensure high feed forces and repeatable positioning.

Measuring system
Incremental measuring systems in the feed motor are installed in all linear axes.

Clamping device
The clamping device is a hydraulic hollow clamping system with bar passage up to ø 45 mm including programmable clamping stroke monitoring and direct measuring system. The time-consuming changeover with the tool is thus replaced by simple teaching in teach-in mode.

Lubrication
The MAXXTURN 45 is lubricated by an automatic central lubrication system with consumption-optimized pulse lubrication thanks to the integrated pressure and quantity monitoring.

Coolant system
A central coolant supply through the VDI interface on the turret and through the tool holder guarantees optimal cooling and lubrication of the machining process. In addition, an additional coolant line for cleaning the clamping devices and the work area is installed.

Hydraulic
device The hydraulic device is a high-pressure compact hydraulic system with a pump and fine filtering in the pressure line, with which the clamping pressure can be adjusted more sensitively. This is the prerequisite for clamping delicate workpieces on the main and counter spindle. Thanks to its compact design, it only requires a small footprint.

Machine cover
The cover of the machine includes a closed machine paneling with chip guard door monitored at the end position on the operator side and a generously dimensioned viewing window made of laminated safety glass. Finished parts pick-up device

(option)
The pneumatically operated pick-up device is used to dispose of the finished parts from the main or counter spindle. The parts go gently into a precast box outside the work area. Maximum finished part length 120 mm; Max.
ø 45 mm; Max. Weight: 2 kg

EMCONNECT
EMCONNECT stands for connectivity and networking of the production environment and is a digital process assistant for the comprehensive integration of customer and system-specific applications related to machine control and the production process. The focus of the operating procedures is on the user and his requirements: the work processes should be designed more efficiently and the usual high reliability of the machines should be maintained in all operating modes.

With EMCONNECT, the user has access to important additional functions directly on the control panel. This means that access to all important information, data and systems takes place directly and centrally on the machine. With the modular system from EMCO, project and customer-specific applications can also be implemented with great flexibility. EMCONNECT is therefore the key to optimal work processes and increased productivity.

The selection of available apps is constantly being expanded. For example, the Shopfloor Data option for machine and operating data acquisition (MDE / BDE) is now available. It provides comprehensive monitoring of all machines and organization of processes in the production area. This product particularly distinguishes itself from machine and manufacturer independence as well as mobile access to the machine status via smartphone or tablet. The EMCONNECT Data Service is in preparation for targeted, preventive maintenance to reduce machine downtimes to a minimum. We will also be happy to show you this application and the associated new possibilities to increase further optimization potential in the production process in a first version at our booth.
