Versatile CNC miller machines dies too
The portal design Hermle C1200 can be specified with either a rigid table or NC swivelling rotary table to cater for complex aircraft type components or mould and die work.
The portal design Hermle C1200 can be specified with either a rigid table or NC swivelling rotary table to cater for highly sophisticated aircraft type components requiring five-axis machining in small and medium batches or die and mould machining In either case, a choice of 10,000, 16,000 or 24,000 rev/min spindle is available and high acceleration rates of 4m/sec2 in each axis to 30m/min rapid traverse minimise lost spindle machining time due to repositioning

Grinding wheels and nozzles changed automatically
Developed to achieve the most cost-effective grinding, the latest Schutte WU 305 five-axis universal tool and production grinding machine is equipped with an automatic wheel changer.
Now available from Traub Heckert UK of Brackley, the C1200 V has a 1,400mm by 900mm table and a machining volume of 1,200mm in X, 900mm in Y and 500 mm in Z.
Meanwhile, the C1200 It has been developed to provide five-axis simultaneous machining for which seven have just been installed in the UK.
The machine features an 800mm diameter NC rotary table with + 15deg to -97deg swivel and axis travels of 1,200mm in X, 800mm in Y and 500mm in Z.

High speed machining for die and mould industry
Developed for high accuracy, up to 40,000 revs/min, three-axis, simultaneous 3-D profiling, the OPS high speed vertical machining centre is very compact, stable and cost-effective
The extremely rigid, closed back portal design of bed and column structure is manufactured from a mineral casting, which has low thermal conductivity and high vibration damping qualities.
It provides the ideal platform to optimise contour machining accuracy and surface finish while providing the basic criteria to achieve high levels of tolerance and repeatability.
Here, through direct linear scale measurement, the resolution is qualified as being 0.0001mm.
The standard spindle on both machines is 25 kW giving 20 to 10,000 rev/min.
It has water cooling and options of SK40 or HSKA63 taper.
Torque is high at 159 Nm and, as standard on both this and the 16,000 rev/min optional spindle, collision protection is fitted to the Z-axis.
The 16,000 rev/min spindle develops 130 Nm of torque at 1,100 rev/min from the 15 kW AC drive while the optional high speed machining 23 kW drive powers a 20 to 24,000 rev/min spindle.
Tool magazines are of a ring design with 30 pockets which are mounted under the cross beam of the main mineral cast portal frame.
In addition, by using additional magazines these can be expanded to 87 tools.
All tools are protected from the working area and automatic change takes 6.5 secs via a spindle pick-up process which avoids the use of toolchange arms.
Maximum tool size is 300 mm long by 80mm diameter or 125mm diameter with adjacent pockets vacated.
A laser system enables precise automatic tool length and size measurement and provides tool breakage monitoring.
Control is by Heidenhain TNC 430 contouring system with integral hard disk, 3-D interpolation and real time graphical simulation or Siemens S840D with NURBS- Interpolation.
