Latest machining news from the milling and turning teams at Ultra
Ultra Precision recently completed the machining of twelve of these discs. The set comprised six off left and right hand versions. Initially within our turning department they were machined on one of our 3 chucking CNC lathes, before transferring to our CNC milling department, which comprises 12 CNC mills.
The part features 2 millimetre wide 'O' ring grooves in stainless steel 316, as well as a variety of milled features including blind tapped holes and pockets.
Our prototype and tooling department then produced a fixture so that the parts could be held on one of our three rotary axis and then had the grooves milled around the outside.

Ultra success on innovative large scale assembly project
We were delighted to have recently won and completed an order for 1000 assemblies. The assembly consisted of 10 parts manufactured by us in house and a number of fixing parts sourced by us.
The 11 parts were machined over nine of our thirty six CNC machines. This highlights the extensive flexibility that our array of machines allows us to have.
Seven of the parts were manufactured from stainless steel and four from aluminium. Three of the aluminium parts needed different surface finishes. We accompanied these with a number of out sourced items such as bearings, screws and washers – some of which were sourced at our discretion and some from the customers chosen source.
We utilised all three of Citizen M32 sliding head machines to produce four of the parts. One of these allowed us to use the extra x axis it has to mill a feature in one of the faces to a 0.1mm tolerance. These sliding head machines allow you to turn and mill parts complete using turning tools and driven milling tools in both a turret and on a platen above the main spindle. The machines also have a sub-spindle which allows the machine to produce features on the second side in one single cycle. We also utilised two of our 20mm size sliding head machines to produce two of the parts.
Five of our parts were machined on our large mill turn centres. These machines have two spindles – a main and a sub-spindle. These are served by two turrets with driven tools that allow us to turn and mill complete parts in one cycle. Four of these were machined from lengths of bar and one from billets. Our Doosan Pumas allow us to switch from bar up to 65mm, to billets up to 8 inch diameter. We also utilised on Doosan Lynx and our Miyano 65.
After assembly in our dedicated assemble room, the parts are tested on an electronic test rig to prove functionality
The order was completed by specialist packaging that was sourced to house the completed part before it is sent to China.

New Haas machine joins our Milling section – See it in action!
Ultra Precision recently took delivery of a new Haas VF-2SS CNC milling machine. This impressive machine is one of 11 CNC milling machines and our third super speed machine. The super speed refers to the 12,000 rpm spindle as well as rapid feed rates and quick tool changes
With a travel size of 762 mm in X, 406mm in Y and 508mm in Z. The through spindle coolant also allows for faster material removal rates. Built in Renishaw probes assist with more accurate part loading.
