The machining 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 EMCO Maier VT 160 and VT 250, when linked with one of three basic conveyor options -- oval, meander, and crossover-meander designs -- provide 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. Each option footprint is only 21 m2.
The VT 160 and VT 250 "Duo" solutions can each perform complete machining of a workpiece (two face machining with the OP 10 and OP 20). In addition, the production of two different workpieces is possible (part A on machine 1, part B on machine 2).
With the VT 250 and 160, the user can opt for different versions and additional. 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.
“The automation solution available with Duo supports a variety of customer-specific solutions - with or without a workpiece carrier (or pallet). The implementation of the Duo cell is compact and space-saving, and it offers unrestricted access for loading and unloading workpieces,” said a company spokesperson.
Multiple machine operation and short set-up and retooling times reduce wasted time. Optimized production processes and short chip to chip times for the vertical machines create ideal conditions for complete machining with high quality and efficiency.
The machines feature steel-welded construction of the rigid, vibration-damping machine bed and 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 can handle even 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 Ř 40 mm with lash and maintenance free 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 eliminate telescopes; guideways and seals are protected against swarf. The fully enclosed guarding permits economically and ecologically meaningful part removal, as the machine door stays closed even when picking up the workpiece.
Salzburg-based EMCO is one of Europe's leading machine tool manufacturers. Its two commitments "Made in the Heart of Europe" and "Design to Cost" are the main factors in the success of the international company, which represents excellent production quality and functional design. EMCO is part of Kuhn Group and currently employs around 800 staff at a total of 4 production facilities in Austria, Germany and Italy.
