A new concept in machine tools that is able to combine multiple simultaneous processes within its single compact modular design structure is to be installed on the Citizen Machinery-Miyano stand at EMO 2013 in Hannover.

According to Citizen, this ‘breakthrough’ in non-traditional machine-tool design, which comprises three independent machining units, would be able to carry out a range of production cycles, including turning, milling, grinding and measurement from either bar, billet or forged materials.

The next-generation MC20 concept will be an open invitation to visitors to discuss productivity benefits with the development team on the stand, which will also incorporate several new European machine launches and prototype machines from both Citizen and Miyano stables.

EMO 2013 will take place on 16–21 September.

Also on show at EMO 2013

  • Citizen will launch fourth-generation M-Series machine — the M16 Vlll CNC sliding-head turn-mill centre — which can reduce cycle times by a further 20 per cent. It introduces a third Y-axis for the back tool post and a 135deg B-axis able to carry four tools for front and back machining.
  • A new Citizen L12 will be unveiled that is able to be quickly set for both long and short lengths of work by fitting or removing the guide-bush assembly. The machine has a 35m/min rapid traverse with fast acceleration, a 27-tool capacity configured around a high-speed 15,000rev/min spindle and 10,000rev/min backspindle, all under the Citizen Cincom seven-axis control.
  • Visitors will be able to view the prototype of the next-generation, 39-tool, 20mm-capacity Citizen L20-XII, which introduces further levels of versatility with a B axis in addition to the Y axis. Simultaneous machining using the gang and opposite tool posts is enabled, which now carry six fixed and rotary tools in two rows of three.
  • Miyano will launch the latest 10-axis-plus-three-auxiliary-axes BNA-42GTY, a 42mm-capacity CNC turning centre that incorporates Citizen’s Cincom software. The machine is able to reduce non-cutting times by up to 27 per cent with up to three tools cutting simultaneously.
  • A prototype of the forthcoming Miyano twin-turret BNE-51MSY 51mm-capacity turning centre will be shown, again utilising the latest Citizen control functions and introducing third axes (X3 and Z3) to service the second spindle giving for simultaneous machining. In addition, axis strokes have been extended for both turrets.
  • Developed for the fuel injection and hydraulics sectors, new machining cell is to be launched by Miyano. The LZ -01RY2 has fully integrated high-speed auto-loading to service the machine configuration, which includes traversing main and secondary side-by-side spindles and the options of a 10- or 12-station Y-axis driven tool turret.

Citizen Machinery

Citizen is the world leader in CNC sliding head ‘one-hit’ turn-milling technology. It has a range of machines having a maximum bar capacity between 4 mm on the compact micro-machining capable Citizen R04 to 32 mm on the top of the range Citizen M32-VII which has the added capability of two Y-axis cross-feeds.   

The M32 can carry up to 80 tools, of which 20 can be driven, and can cut with three tools simultaneously giving low cycle times and high levels of productivity.  Also, fully automated unmanned cycles can be utilised through an integrated gantry option and conveyor system that helps ensure damage free parts during uninterrupted batch production.  A high pressure 2,000 psi CoolBlaster coolant system is a further option to optimise swarf control, tool life and machining difficult materials.

Following the acquisition in Japan in 2008 of 65 per cent shares in Miyano, the fixed head turning centre specialist, the two companies are maintaining their separate high profile brand names utilising a single sales operation.  However, turn-milling solutions from bar up to 64 mm diameter can now be provided.  In addition, with the Miyano range of turning and turn-milling machines for chucking operations, cell-type applications can now be accommodated with a wide range of automation options.
