At the Coalville facility of Terex, a mobile crusher machine manufacturer, a large-capacity Doosan DBC160 horizontal borer from Mills CNC has been installed.

Used to produce the high-accuracy bores, holes and threads found in the fabricated sections of Terex’s mobile crushers, the DBC160 accommodates sections that can weigh up to 30 tonne. Machining operations can be relatively long and, such is the need to maintain productivity, that high removal rates are an ongoing requirement. Up to 70 mobile crusher machines are manufactured at Terex’s Coalville facility every month.
Jason Toon, operations and facilities manager, says: “The machine specification we’d drawn up included the requirement for a large 3 m Y axis. We didn’t realise at the time that the new Doosan DBC160 borer could be supplied with such a large Y axis, although when we found out, we were naturally interested. The DBC160 is a new machine and we were going to be the first customer in the UK to buy one. This, plus the performance-critical nature of the investment meant we had to get it right first time.”
The DBC160 is a large-capacity, moving-column type borer equipped with a 160 mm diameter boring spindle (45 kW/2000 rpm). Workpieces measuring 3400 mm in diameter, and up to 20 tonne in weight, can be accommodated on the machine’s B-axis rotary table.
“We have been delighted with the DBC160 machine’s performance, and cannot speak highly enough about Mills CNC’s dedication and commitment, which have been first-class,” concludes Toon.

The huge growth in fish farming in recent years is proving good news for a small precision engineering company based near Spalding.

A one-off job 10½ years ago has turned into a major stream of business for Channing Engineering, which employs eight people at its workshop in the village of Pinchbeck.
Run by Colin Channing, the company makes parts that are in high demand for fish farming businesses in Norway, the Faroe Islands and Canada. As a result, more than half of its work is now exported and, unlike many, the firm has no worries about the implications of Brexit with all of its main sales destinations outside the EU.
With business continuing to grow due to its reputation for quality and reliability, Channing and his team have decided to replace one of the company’s Bridgeport machining centres, working with the Engineering Technology Group (ETG) to purchase a new Hardinge GX710S.
“The previous machine was a highly reliable piece of kit, so it made sense to get another Bridgeport,” points out Channing. “It’s been a while since we’ve had to replace a piece of equipment and it was the first time we had worked with ETG. Everything went very smoothly and, when any issues did crop up, we received a rapid response, which is just what you want with a significant investment.”
The Bridgeport Hardinge GX710S is a three-axis vertical machining centre with 20 tools on an ATC carousel and a single spindle speed of up to 12,000 rpm. Table size is 800 x 400 mm, while travels in the X, Y and Z axes are 710, 400 and 430 mm respectively.
