StarragHeckert Introduces New 'Athlete', the HEC 1600
Ultimate sporting achievements are rewarded with the accolade "world-class
athlete". For machining centers, too, it is only the outstanding results which count: they are required to produce even faster, more powerfully, more exactly and with greater cost-efficiency. The latest generation of large-scale machining centers - HEC 1000 Athletic, HEC 1250 Athletic and HEC 1600 Athletic - addresses precisely these demands.
The manufacturing of large and heavy workpieces with edge lengths of up to 3,000 mm and weights of up to 13,000 kg is now even more economical and flexible. Features of the new HEC Athletic Series are:
o Increased interference ranges (to 3,000 mm)
o Optimum work space conditions with improved traverse end positions of the workspindle (225 mm before pallet center)
o Rapid traverse rates up to 40 m/min
o Higher spindle power (up to 53 kW) and speed (up to 7,500 rpm)
o Suitable for tools up to 800 mm in length
o Optimum coolant preprocessing and swarf disposal
Flexibility and modular construction are characteristics of tool and workpiece handling, as well as the main spindle design. It is possible, for example, to choose between a horizontal main spindle with AC motor or motor spindle, an extendable NC quill and a swivelling horizontal / vertical head for 5-sided machining. This enables the machining center to be matched ideally to customer requirements.
Whether as a stand-alone machine, as a production cell with additional pallet storage, or integrated into flexible manufacturing systems, the HEC machining centers of the Athletic Series guarantee cost-efficient and highly accurate production.
The HEC 1600P is especially versatile, starting with its compact footprint (14,500 x 9,800 x 5450 mm) with optimized subassemblies in crossbed design for tailor-made solutions. X-axis travel is 2,800 mm, Y-axis is 2,000 mm and Z-axis, 2,100 mm. The interference range is up to 3,000 mm, and the extendable NC quill stroke is 500 mm. High dynamic response in the displacement axes at rapid traverse rates up to 40 m/min in the linear axes is through digital servodrives
The work spindle is powered by a 50 kW AC motor with a stepless speed range of 20..4,000 rpm. The toolholder taper is HSK-A 100 (SK 50, CAT 50). Outstanding machine accuracy of linear axes - positional deviation of <0.007 mm, repeatability of <0.004 mm and max. backlash of <0.004 mm - translates to greater precision of complex parts.
Adding to the flexibility and versatility of the HEC 1600 is an NC quill, which provides a quantum leap in machining large gearbox housings, torque support and planetary gear carriers (think aerospace and power generation: very large components.) The NC quill has the following productivity parameters: Torque, 2,150 Nm; drive output, 56 kW; speed, 4,000 rpm, with a 5 sec warm-up time; NC quill travel, 750 mm and rapid traverse, 1,000 mm/min.
The NC quill's accuracy is largely the result of automatic temperature compensation for thermal influences and thermal stability of the quill by cooling the quill and the quill bearing with a separate cooling unit.
The HEC 1600's NC rotary table has a clamping area of 1250 x 1600 mm, a backlash on reversal of 3°, a resolution of 0.001° and an interference range to 3,000 mm. Maximum table load is 13,000 kg and maximum workpiece height is 2,200 mm.
The HEC Athletic Series of precision machining centers offers different variants of automatic pallet changers - either a double pallet changer (standard on the HEC 1600) or triple/quadruple changers as an option. This kind of flexibility is critically important as business demands grow and parts proliferate.
The automatic tool changer (ATC) handles tools to 325 mm in diameter (340 mm with tower) and 800 mm in length. Maximum tool weight is 35 kg (50 kg with tower). Tool handling with chain magazine has 60 or 80 magazine locations for tools up to 325 mm in diameter (T-type tools up to 500 mm in diameter). Tool change: 12 sec. with a tool weighing 15 kg. An optional tower magazine has up to 240 tool locations.
The HEC 1600 offers optimum conditions for dry and wet machining. Contributing factors include extraordinarily fast swarf disposal thanks to two swarf conveyors, minimal quantity lubrication for dry machining, external coolant supply via nozzles at 120 l/min and internal supply through the spindle center at a pressure up to 60 bars. The coolant reservoir is 2,500 l. Flexible coolant preprocessing at the cutting material either with a reversible flow filter, turbo filter or fleece gravity filter. Low maintenance through grease lubrication for workspindle, ballscrew and sectional rail roller guides.
State-of-the-art process control and monitoring with Sinumerik CNC 840 D (Fanuc 31i optional) and integrated PLC. Tool life monitoring, 3D sensing probe and direct tool breakage monitoring through laser light-barrier. Tool gauging is via laser, in addition to tool speed monitoring, power and the torque monitoring and tool coding and remote diagnosis.
The HEC 1600 provides a high degree of user-friendliness through a swing-type operator panel, good accessibility at the load-unload station, a completely closed work space paneling, wave shower in the work space for workpiece cleaning and work space emissions extraction.
This new HEC Athletic Series machine also provides the potential for expansion of your fields of application through a mold kit for the tool and die industry, as well as through the existing control options, such as shaping, milling of cylinder paths and spline interpolation. Further, a highly increased degree of automation is possible through the attachment of semicircular magazines with five or six locations for workpiece pallets and linear magazines in one or several planes which facilitates the seamless expansion into flexible manufacturing systems.
