Of travelling-column floor-type design, the Union P/PC range of horizontal live spindle boring and milling machining centres from exclusive UK agent, Ward CNC of Sheffield, are believed to be the most flexible and universally applicable machines for processing large workpieces accurately and consistently. This is courtesy of features such as auto head and tool changers (up to 80 tools) and the optional NC facing head, pick-up system and NC rotary table - coupled with Union's established build principles of cast iron construction for rigidity and up-to-date linear guideway technology that promotes both high specification and performance. Between them, the P/PC 130 and 150 variants have X axes travels from 4000mm up to 10m and larger, Y axes from 2000mm up to 3500 mm and Z axes of 800mm.

W axis (boring spindle) is 750mm and the 50/60kW motor produces maximum speeds of up to 3,000 revs/min.

The machines are constructed with heavily-ribbed beds featuring backlash-free compact roller guides of the table saddle and column infeed motion for precise, stick-slip free motion.

The column assembly is of rigid box-type cast iron construction, again with precisely machined faces for the preloaded, compact roller guides.

Of solid cast iron construction, the headstock accommodates a high-precision main spindle system by means of preloaded spindle bearings with lifetime lubrication.

Boasting hardened and ground gears for automatic speed range changes, the gearbox is thermally stabilised.

Backed by Union's over 140 years' of manufacturing know-how in Chemnitz, Germany, the P/PC machines are being offered alongside Union's latest generation table- and cross bed-type CNC horizontal live spindle boring and milling machining centres by Ward CNC, a company with vast experience of the brand in the UK.
