Five axis MC optimised for mould and die
work
High precision, rigidity and full five-axis interpolating capability are features of a machining centre optimised for mould and die, aerospace and complex surface machining work.
High precision, rigidity and full five-axis interpolating capability are features of the new Toyoda FH80S machining centre, which has a table capacity of up to one tonne The design has been optimised for die and mould work, production of aerospace components and other applications requiring machining of complex surface geometry on medium to large components

Universal grinder a major step for Toyoda
Toyoda has announced the GU4x100, the first universal grinder ever built by the Japanese manufacturer.
Toyoda's UK first for cylinder head production
A travelling-column machining centre linked to a space-saving pallet pool system for storing 10 pallets on two levels has increased cylinder head production capacity at Ruston
The machine is based on Toyoda's established horizontal machining centre design that includes double ballscrews on the Y-axis, but with the addition of a trunnion-mounted table to provide A-axis and B-axis rotary movement of the workpiece.
This format is said to offer maximum rigidity for five-axis machining, as trunnion mount and bearings can be sized without compromise.
For ease of program development and maximum rigidity, the surface of the rotary (B-axis) table is along the same line as the axis of trunnion rotation (A).

Spindle speed options up to 40,000 rpm and cutting feed rates up to 30 m/min are notable features of the new Toyoda FH63M horizontal machining centre developed for mould and die machining.
M-C designed for mould and die machining
During a recent Open House, Toyoda Machinery and Engineering Europe demonstrated its FH63M machining centre, which is purpose-built for mould and die work.
The fifth axis is either driven from one side, in which case maximum payload is 600kg; or the dual drive version provides the maximum 1,000kg table capacity.
The dual drive tilt / turn table is also more accurate, offering positioning repeatability of +/-1 arc seconds compared with +/-3 arc seconds for the single drive arrangement.
The table is capable of supporting a 800 x 800mm pallet and offers tilt movement of +15 to -100 degrees of arc in A, combined with 360 degrees of rotation in B.
Linear axis movements available are 1100mm in X by 1150mm in Y by 1150mm in Z.
Rapid feedrates are 15m/min in X, 24m/min in Y and Z, 2 rpm in A and 4 rev/min in B.
A range of BT 50 taper spindle options is available according to the application.
They include a 22kW/14,000 rev/min spindle with ceramic bearings for aluminium machining, a 30kW / 6,000 rev/min spindle for general ferrous work, and a 30kW / 15,000 rev/min spindle for high speed ferrous machining.
Spindle refrigeration is available as an option.
Standard tool storage is 40, but magazines of up to 240 tools capacity may be specified.
Maximum tool weight is 35kg, and ATC time is two seconds for a 15kg tool.
Control uses Toyoda's 'AI nano' contouring software running on a powerful Fanuc 16i CNC system.
The software has been developed to offer high accuracy at high speed through a 180-block look-ahead capability.
Options available include NURBS interpolation.
Linear machining feed rates up to 15m/min are programmable and accuracy-enhancing options include linear scales and high resolution rotary encoders.
