The new UNIVERSALTURN 50 from EMCO.
With the new high-performance UNIVERSALTURN 50 turning machine, EMCO presents the first model in a forward-looking machine series for the efficient, complete machining of bar and chuck workpieces. With its dynamic drive systems, it offers increased productivity, accuracy, and machine rigidity for turning and milling of complex parts.
The compact UNIVERSALTURN 50 features a bar capacity of 51 mm. The integrated Y-axis with a long guideway enables stable turning and expands milling functions. The compact counter spindle can take over workpieces in the correct position and with high precision for rear-side machining. This eliminates an additional machining operation, reducing downtime.
Depending on the configuration selected, applications include components for hydraulics and pneumatics, mechanical and plant engineering, automotive and engine technology, as well as applications in medical technology, fastening and transport technology. The machine is also suited to produce sliding and rolling bearing parts as well as components in defense technology, where maximum precision and process reliability are required.
Two different bar loading concepts are available: short bar loaders, such as the IRCO ILS-MUK, offer an economical and space-saving solution for automatic reloading. Advantages include low investment costs and space requirements, low-noise operation, and a clean machine room without oil contamination. Alternatively, 3-m 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 EMCO parts catcher.
Various automation concepts are available for automatic loading and unloading and 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.
Additional Highlights of the UNIVERSALTURN Series
The high-performance tool turret for 12 quick-change toolholders (VDI30/BMT45P) allows a wide range of demanding machining operations. With a speed of 5,000 or 12,000 RPM and a drive power of 4 or 8.8 kW, drilling and precise milling are possible.
The UNIVERSALTURN 50 features the modern SINUMERIK ONE control system from Siemens. This offers an intuitive, dialog-based programming system and seamless integration into digital manufacturing processes. A version with FANUC 0i plus control is also available.
Technical Details
The machine bed of the UNIVERSALTURN 50 is designed as a rigid, vibration-damping cast iron construction and forms the central basis for the stability, precision and durability of the entire machine. The solid design offers optimum power absorption combined with high thermal stability. The specially designed structure of the machine bed provides an optimal basis for the integration of dynamic axis systems and automated loading devices, the company reported.
The UNIVERSALTURN 50 M and MY are equipped with a powerful main spindle (30 kW) with belt drive. High drive power and an optimized torque curve enable economical machining of bar stock and workpieces in chucks. Large precision ball bearings with maintenance-free lifetime lubrication provide smooth operation and long service life. A brushless AC drive allows a wide speed range with enhanced rotational characteristics. For increased precision in milling operations, a high-resolution encoder is mounted directly on the spindle.
The integrated spindle motors (ISM) of the UNIVERSALTURN 50, mounted in large precision bearings, offer a wide speed range and enhanced 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 help 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 helps ensure reliable removal of the workpieces. A hollow clamping cylinder with 50 mm passage is available as an option-it is especially suited for unloading long shafts through the counter spindle.
The UT50 M+MY toolholder is equipped with a 12-fold VDI30 system, which has an integrated tool drive for drilling and milling operations. The turret always switches to the next tool via the shortest swivel path without lifting. According to the company, the option of accommodating driven toolholders with DIN 5480 couplings at every second station means the turret is a compact yet powerful solution for multitechnology machining.
The tool turret in the UT50 SMY version (direct drive) is designed for machining operations with a high proportion of milling. It features a BMT45P interface with 12 positions and integrates dual motor technology: one servo motor drives the swivel movement; another water-cooled motor, integrated in the turret disc, drives the toolholders 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 a wide speed range (0-12,000 RPM) at 100% duty cycle.
The C-axis is part of the standard equipment. Due to a direct, contactless encoder, it offers an angular resolution of 0.0001°, ideal for high-precision contour milling. The absence of belt drives reduces mechanical losses, while standard holding brakes enable reliable position holding.
The optional Y-axis is integrated into the machine structure and inclined at 60° to the X-axis, minimizing overhang lengths and enabling rigid machining without geometric interference. It is suited for complex turning and drilling work as well as for safe milling.
Dynamic three-phase drives in all linear axes with preloaded recirculating ball screws offer high feed forces and repeatable positioning.
Absolute measuring systems are used for linear axes. No reference point approach required. Positioning accuracy according to VDI3441 in XYZ: 0.003 mm/0.003 mm/0.003 mm.
The clamping system with a bar clearance of o50 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 help ensure maximum gripping reliability.
The UNIVERSALTURN 50 is lubricated by an automatic central lubrication system with consumption-optimized impulse lubrication due to integrated pressure and quantity monitoring.
Central cooling system with standard pressure of 15 bar via the turret tool interface and flushing of the working area is included.
The hydraulic system is a compact high-pressure device with a pump and fine filtration in the delivery circuit. With its compact design, it requires only a small installation area.
The enclosure features 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.
The pneumatically operated pick-up device (optional) 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. dia.: o51 mm; max. weight: 2 kg.
EMCONNECT (only available with UT50 SMY) offers connectivity and networking in the production environment and is a digital process assistant for the comprehensive integration of customer- and system-specific applications for machine control and production processes. The user and their requirements are at the heart of the operating procedures: the aim is to make work processes more efficient and maintain high level of reliability in all operating modes.
MCONNECT gives users access to important additional functions directly on the control panel. This means that all important information, data and systems can be accessed directly and centrally on the machine.
EMCO's modular system also allows project- and customer-specific applications to be implemented with a high degree of flexibility. EMCONNECT is therefore the key to optimal workflows and increased productivity. The selection of available apps is constantly being expanded.
