Machining Centre built in Taiwan matches Japanesse quality and performance

Machining Centre built in Taiwan matches Japanesse quality and performance

Added to MTDCNC by Whitehouse Machine Tools on 09 January 2013

Anyone looking to produce high precision components within a nominal one-metre cube machining envelope would do well to consider the new, low cost Akari HS-630i horizontal machining centre. This is the view of Whitehouse Machine Tools, Kenilworth, sole UK agent for the Taiwanese manufacturer, Averex Automation (www.averexcnc.com).

Incorporated into the 4-axis, twin-pallet machine are components similar to those used by leading global machine tool manufacturers. They include THK roller guideways, Tsubaki ballscrews, a Tsudakoma full 4th axis rotary table, and 30-bar coolant delivery through a BT 50 BIG-PLUS face-and-taper-contact spindle.

Artificial intelligence contour control with 200-block look-ahead and jerk control within the Fanuc 31iMB Nano CNC enable accurate and very productive, high-speed profiling. Users will also appreciate the rigidity of the 18-tonne machine, which is built around a single-piece casting, and the 600 Nm of torque delivered by the 47.5 kW / 10,000 rpm spindle motor. An optional spindle provides 1,309 Nm / 55 kW / 6,000 rpm.

Rapid traverse at 50m/min in each of the 1,050 x 900 x 1,020 mm linear axes, acc/dec at up to 1.4g and 2-second exchange of BT 50 tools from the 60-station (optionally 120- or 220-station) magazine all help to minimise non-cutting time.

The flexible manufacturing centre allows prolonged periods of unmanned machining. Large batches, small-lot multiple-part runs, and even ones and twos may be produced cost effectively. Thermal control of the ballscrews and nuts, thrust bearings, Y-axis servo mounting and spindle cartridge by means of recirculating, chilled oil ensures high precision metalcutting.

Field expandability by retrofitting a 6-station automatic changer for 630 mm square pallets is an option for OEMs and subcontractors wishing to minimise capital outlay initially and expand their operations later on.

The Akari HS-630i horizontal machining centre joins a smaller HS-450i model launched during the first half of 2012. The first one in the UK has been sold to Nisan Engineering, a subcontractor in Leicester, which takes delivery of the machine in January 2013. The firm works for a variety of different sectors, such as medical, motorsport, rail, marine and specialist vehicles, manufacturing precision components in small to medium batch quantities, mainly in steels.

The decision to select the Akari machine was partly down to its comprehensive specification, but also due to the willingness of the Whitehouse applications team to develop a manufacturing process that minimises set-up and changeover times
