Thames Ditton-based NCMT Ltd (www.ncmt.co.uk) says MACH 2018 will mark the UK launch of the DA300 five-axis trunnion-type vertical-spindle machining centre from Makino (Hall 19 Stand 640).

The machine on display will include a Cellro robotic system for automatically loading and unloading components.

The DA300 machine is aimed at the five-sided and fully interpolative five-axis production of complex components in one clamping.

Equipped with integral direct-drive motors for the swivelling (+30 to -120deg) A-axis trunnion, and for C-axis rotation of the 340x 300mm table, the machine features a 20,000rev/min 22kW HSK-A63 spindle capable of milling, drilling and tapping.

A 60-tool magazine ensures the availability of an extensive selection of cutters to tackle complex parts or component families.

NCMT says that the table is fitted with pneumatic ports for easy integration of an automated pallet-change system, to provide quick component exchange.

Makino offers two standard workpiece pallet systems that can be factory-fitted or retrofitted: a seven-pallet arrangement, expandable in the field; or a 19-pallet system.

Alternatively, an Erowa chuck-type pallet system for automated component handling can be attached (in a similar way to the Cellro equipment on display).

The Fanuc-based Professional 6 CNC system with optional Super Geometric Intelligence 5 (SGI.5) provides streamlined screen layouts, operator assistance and new macros to increase productivity.

For example, a G-code drilling cycle enables the tool to arc from hole to hole, instead of following a square path, reducing non-cutting time by as much as 15% when drilling typical hole patterns.

Meanwhile, a vision sensor outside the machine’s work zone detects broken tools to ensure cutter integrity without impacting cycle times.

Workpieces up to 450mm in diameter and 400mm high, with a maximum weight of 250kg, can be machined within a 450 x 620 x 500mm working volume at feed rates up to 60m/min.

The rotary A and C axes offer speeds of 100 and 150rev/min respectively. Acceleration and deceleration to and from full speed takes 1.5sec.

Also on the stand will be the EDAF2 die-sink EDM machine, which features integral cooling of the Y- and Z-axis cast components to ensure long-term accuracy.

Table size is 550 x 350mm, while the dielectric reservoir is built into the base casting to further improve thermal stability and minimise the machine’s footprint.

Free access to the working area is provided by a programmable three-sided drop-tank system.

Unattended machining is extended by automatic electrode exchange and automated workpiece delivery and removal options.

Fluid cooling maintains the dielectric at a constant temperature for stable ‘burning’ conditions. A C-axis head is also featured.

The machine uses Makino’s latest Hyper-i control system, with an interface similar to that found on tablets and smartphones.

Moreover, the new on-board programming system, Makino Program Generator, has been designed to simplify use of the control: by providing answers to prompts and inputting basic data, even novice operators can generate efficient and safe burn routines, says NCMT.

The new program generator also allows for the programming of multiple electrodes and multiple burn locations.

One of Makino’s most technologically advanced wire-cut models, the U3 HEAT, will also be presented. This offers X-, Y- and Z-axis travels of 370, 270 and 220mm respectively.

Workpieces up to 770 x 590 x 220mm (with a maximum weight of 600kg) can be machined.

Other features are reduced wire consumption and a choice of two guide configurations (conventional round or split V) for the 0.1-0.3mm-diameter wire, to accommodate most material types and flushing conditions.

HEAT machines (High Energy Applied Technology) incorporate high-pressure, dual digitally controlled flush pumps and a large-capacity four-step filtration system.
