The new UNIVERSALTURN 50 is a compact and powerful turning entre with a bar capacity of 51 mm, specially developed to meet the growing demands of the market. Based on the proven success concept of the MAXXTURN series,
UNIVERSALTURN 50 combines EMCO technologies with future-orientated developments for maximum efficiency, process reliability and versatility. The highly dynamic drives not only enable fast machining cycles but also ensure the necessary
precision and rigidity when simultaneously machining complex turned and milled parts. Another strength is the integrated Y-axis with a long guideway, which ensures stable turning on the one hand and significantly expands the milling functions on the other.
Depending on the configuration, the machine concept thus offers a scalable and powerful basis for the precise and economical production of complex parts.
Wide range of applications in various industries
Depending on the configuration selected, the manufacturing range includes components for hydraulics and pneumatics, mechanical and plant engineering, automotive and engine technology, as well as applications in medical technology, fastening and transport technology. In addition, the machine is also suitable to produce sliding and rolling bearing parts as well as components in defence technology, where maximum precision and process reliability are required.
Flexibly adaptable automation solutions
Two different bar loading concepts are available for processing bars: Short bar loaders such as the IRCO ILS-MUK offer an economical and space-saving solution for automatic reloading with advantages such as low investment costs and space requirements, low-noise operation and a clean machine room without oil contamination. Alternatively, 3-metre bar loaders from TOP AUTOMAZIONI or FMB enable larger material stocks and thus greater production autonomy. Finished parts are transported from the work area to a parts box or conveyor belt using the proven EMCO parts catcher.
Various automation concepts are available for automatic loading and unloading, which can be individually adapted to production requirements. An integrated mini gantry with double gripper is available as an option. This allows fully automatic loading and
unloading of workpieces beyond the bar passage. All movements are controlled by CNC and executed precisely and quickly by the machine control system. Preformed raw parts can be loaded into the corresponding clamping device in the correct orientation and picked up in the correct orientation.
The highlights of the UNIVERSALTURN series
The Y-axis is fully integrated into the machine structure of the UNIVERSALTURN 50. This guarantees maximum stability and the highest precision when manufacturing complex workpieces. The generously dimensioned guide distances of the Y-axis enable particularly stable turning and at the same time significantly expand the possibilities for complete machining.
Another highlight is the compact counter spindle, which can take over workpieces in the correct position and with maximum precision for rear-side machining. This eliminates an additional machining operation, reducing downtime and significantly increasing productivity and delivery speed.
The high-performance tool turret for 12 quick-change tool holders (VDI30 / BMT45P) allows a wide range of demanding machining operations. With a speed of 5000 or 12000 rpm and a drive power of 4 or 8,8 kW, both powerful drilling and precise milling are possible without any problems.
The UNIVERSALTURN 50 is currently available exclusively with the modern SINUMERIK ONE control system from Siemens. This offers an intuitive, dialogue-based programming system and seamless integration into digital manufacturing processes. From 2026, a version with FANUC 0i plus control will also be available to offer customers with a preference for this control system the optimum solution.
Technical details / The machine concept of the UNIVERSALTURN 50
Machine base:
The machine bed of the UNIVERSALTURN 50 is designed as a highly rigid, vibration- damping cast iron construction and forms the central basis for the exceptional stability,precision and durability of the entire machine. The solid design ensures optimum
power absorption combined with high thermal stability – a decisive factor for reproducible machining results over long operating times.
The combination of high inherent rigidity, excellent damping properties and sophisticated geometric design effectively suppresses vibrations and vibration influences. This not only significantly improves the surface quality of the workpieces but also reduces tool wear and thus increases the cost-effectiveness of machining. In addition, the specially designed structure of the machine bed contributes to high positioning and repeat accuracy and provides an optimal basis for the integration of dynamic axis systems and automated loading devices.
Main spindle in UT50 M + MY versions (belt drive):
The UNIVERSALTURN 50 M and MY are equipped with a powerful main spindle (30 kW) with belt drive. High drive power and an optimised torque curve enable both economical machining of bar stock and workpieces in chucks. Large precision ball bearings with maintenance-free lifetime lubrication ensure smooth running and a long service life. A brushless AC drive allows a wide speed range with excellent rotational characteristics. For maximum precision in milling operations, a high-resolution encoder is mounted directly on the spindle – ideal for exact positioning tasks.
Main and counter spindle in UT50 SMY version (direct drive):
The integrated spindle motors (ISM) of the UNIVERSALTURN 50, mounted in large precision bearings, offer a wide speed range and excellent concentricity – ideal for economical machining of steel and high-speed cutting of aluminum. Symmetrically
designed spindle stocks, temperature sensors at the bearing points and liquid cooling ensure high thermal stability and process reliability.
The counter spindle is mounted on a separate roller guide and moves automatically over 510 mm. A stroke-monitored, coolant-flushed parts ejector ensures reliable removal of the workpieces. A hollow clamping cylinder with 50 mm passage is available as an option – ideal for unloading long shafts through the counter spindle.
Tool turret in UT50 M + MY versions (belt drive):
The UT50 M+MY tool holder is equipped with a 12-fold VDI30 system, which has an integrated tool drive for drilling and milling operations. Naturally, the turret always switches to the next tool via the shortest swivel path without lifting. The concept, which has been tried and tested for many years, is extremely reliable, robust and effective. Thanks to the option of accommodating driven tool holders with DIN 5480 couplings at every second station, this turret is a compact yet powerful solution for multi-technology
machining.
Tool turret in UT50 SMY version (direct drive):
The tool turret of the UT50 SMY, designed for machining operations with a high proportion of milling, has a BMT45P interface with 12 positions and integrates dual motor technology: one servo motor drives the swivel movement and another water- cooled motor, integrated in the turret disc, drives the tool holders directly. The operator can influence the swivel speed at any time using the feed override switch. Each position can accommodate driven tools, thus offering maximum operational flexibility
combined with the widest possible speed range (0-12,000 rpm) at 100% duty cycle.
C-axis
The C-axis is part of the standard equipment. Thanks to a direct, contactless encoder, it guarantees an angular resolution of 0.0001°, ideal for high-precision contour milling. The absence of belt drives reduces mechanical losses, while standard holding brakes
ensure reliable position holding.
Y-axis (depending on model)
The optional Y-axis is integrated into the machine structure and inclined at 60° to the X-axis, minimising overhang lengths and ensuring rigid machining without geometric interference. Perfect for complex turning and drilling work as well as for safe milling.
Feed drives
Highly dynamic three-phase drives in all linear axes with preloaded recirculating ball screws ensure high feed forces and repeatable positioning.
Measuring system
Absolute measuring systems for linear axes. No reference point approach required.Positioning accuracy according to VDI3441 in X/Y/Z: 0.003 / 0.003 / 0.003 mm.
Clamping device
The clamping system with a bar clearance of ø 50 mm (2”) is equipped with clamping stroke monitoring via direct sensors, which can be programmed in teach-in mode. The clamping pressure can be finely adjusted and, if required, also programmed to ensure
maximum gripping reliability.
Lubrication
The UNIVERSALTURN 50 is lubricated by an automatic central lubrication system with consumption-optimised impulse lubrication thanks to integrated pressure and quantity monitoring
Cooling
Central cooling system with standard pressure of 15 bar via the turret tool interface and flushing of the working area is included.
Hydraulics
The hydraulic system is a compact high-pressure device with a pump and fine filtration in the delivery circuit. Thanks to its compact design, it requires only a small installation area.
Machine cover
Complete cladding with an electronically monitored front door and a large window made of laminated safety glass. Certain covers can be easily lifted or removed for optimum serviceability and maintenance.
Pre-finished part pick-up device (optional)
The pneumatically operated pick-up device is used to remove the finished parts from the main or counter spindle. The parts are gently transferred to a finished parts box outside the working area. Max. finished part length: 120 mm; max. ø: 51 mm; max.weight: 2 kg.
