CNC driller/miller performs hard
machining
The latest version of the high productivity Fanuc Robodrill introduces the 16iMB CNC control and Alpha i servo control and increased tool capacity to 21 tools, and rapid traverse of 54m/min.
With the launch of the latest version of the high productivity Fanuc Robodrill through 600 Centre of Shepshed, Loughborough in Leicestershire, Fanuc introduces its latest 16iMB CNC control and Alpha i servo control, increases tool capacity by a third to 21 tools, and increases rapid traverse rates to 54m/min with an acceleration rate of over 1.2G The Robodrill series has been an international top- seller, initially as a fast cycling machining centre but then with the development of higher rigidity became popular in the mould and die sector for highly efficient electrode production and hard metal machining

VMC replaces special-purpose machines
By changing the manufacturing process for its bearing cages from two special purpose machines to a fully automated cell, based on a VMC, Danly (UK) has cut change-over times by up to 300 per cent.
In the latest guise, the Robodrill Alpha T21iC once again moves the boundaries in productivity, repeatability and accuracy by adding Z-axis thermal compensation software, on board tool life management software and A1 nano contouring software for high speed milling type applications.
Available in standard 'C' format with X-axis stroke of 500mm Y-axis of 400mm and Z-axis of 330mm, the range also covers a wide stroke 'CL' where the X-axis is extended to 700mm and the ultra-compact 'CS' which is just 980mm wide and ideal for installation as a bank of machines for service by a single operator.
High levels of auto-intelligence has been built into the Fanuc 16iMB control with easier programming using menu-based operation with minimum key strokes and PC-like software for program editing.

Robotised machining cell set up inside 14 weeks
When diesel engine and automotive components specialist secured a major new order to produce front wheel hubs it moved quickly to set up a robotised machining cell inside 14 weeks.
Machining time is reduced using bell-shaped acceleration and deceleration curves giving 1.2G to maximum traverse rate of 54m/min.
There is also immediate switching between feed and rapid traverse through the advanced preview and HRV control which eliminates servo lag and maintains 'least tracking error' when high speed milling.
A further feature that improves cycle times is that a milling cutter will not cut the workpiece when traversing the return path of a cut.
The A1 nano contour control option utilises a 180-block look ahead for smooth and predictive motion generation via the digital servo system.
This system operates in nanometres regardless of whether the program command is in microns.
Meanwhile, with the A1 tool monitoring and life management software, any disturbance to the normal load of the spindle motor is detected and compared against preset limits to initiate a sister tool change from the 21 tool magazine.
Spindle speeds are 8,000 revs/min as standard from a 5.5kW motor or 15,000 revs/min is available as an option from a 3.7kW direct drive.
High speed rigid tapping can be performed up to 5,000 revs/min or 6,000 revs/min respectively.
Meanwhile, a 'quick extraction' tap cycle further reduces tapping cycles and a high pressure, through tool coolant supply option allows drilling speeds and feeds to be further increased.
The Robodrill is now available with various options including simultaneous four and five-axis machining, a high speed 80,000 revs/min auxiliary spindle, twin pallets, robot loading, a Renscan 400 high speed digitising package, mist separation system and vacuum dust collection for dry machining.
