Ajax compiles ‘ideal UK spec’ AJV 700 vertical machining centre package
Ajax Machine Tools International is offering a ready-to-run vertical machining centre package for under £50,000. This is based on a 700 by 400 by 550 mm (or 650 mm Z-axis option) capacity AJV 700. It features a 10 kW spindle delivering up to 15,000 rpm, a high speed 48 m/min rapid traverse and Heidenhain TNC 620 control. Ajax is also including a starter tooling package.
Ajax worked with Semco for over 25 years then bought out its machine tool operation some five years ago. This, UK the supplier says, has enabled it to influence an 'ideal' UK specification for the latest vertical machining centre. The result is high rigidity, a 1.9 by 2.2 m compact footprint machine that is able to provide high orders of spindle utilisation under the Heidenhain control system.
The Ajax AJV 700 is built on heavy duty cast iron bed and column reflected in its net weight of some 3.7 tonne. High performance linear roller guides support a rapid traverse rate of 48 m/min. Chip-to-chip time with the 24-tool magazine of 3.6 sec is achievable over the full standard axis travels.
The direct drive 40 taper spindle is powered by a 10 kW motor and can be specified with speeds of 10,000 or 15,000 revs/min with the arm style tool changer capable of a 1.6 sec tool-to-tool time. Tool sizes can be up to 80 mm diameter (150 mm with adjacent tool pockets left empty) and up to 250 mm in length weighing up to 2 kg. Machine specification includes a spindle chiller and an oil skimmer.
The Heidenhain TNC 620 contouring control provides programming versatility for workshop-orientated single component and series production, says Ajax. It provides DIN/ISO program input through soft keys or via USB or RJ45 network interface. Program memory is 2GB. Fixed cycles are included for drilling, tapping, thread cutting, reaming and boring with additional cycles for linear and circular hole patterns, multi-pass milling of plane surfaces, rough and finishing of pockets, slots and studs.
To facilitate extended uninterrupted metal removal efficiency, full in-cycle wash down through two high pressure jets aids clearance of swarf into the spiral chip conveyor. A flat style chip conveyor is available as an option as well as through-the-spindle 20 bar coolant feed and mist collection. Also available as options are fourth and fifth axis tables and Fanuc Oi D control. Renishaw auto measuring, tool measurement and probing systems can also be optionally supplied.
