Among them will be the company’s latest DMC 80 FD DuoBlock universal machining centre (equipped with a pallet changer), which offers improvements of 30% in the core characteristics of precision, performance and efficiency, says DMG Mori.
The DMC 80 FD DuoBlock is capable of performing heavy-duty cuts on rotational parts – for instance in aerospace applications – with its HSK100 B-axis interface and PowerMaster 1000 spindle, which provides power of 77 kW, a maximum speed of 9000 rpm and torque of 1000 Nm. Additionally, DMG Mori offers the integration of grinding technology for the DMC 80 FD DuoBlock, guaranteeing surface finish to Ra <0.3 µm. For further information www.dmgmori.com

Hydrafeed: More than meets the eye

A recognised manufacturer of barfeed systems for CNC lathes, Milton Keynes-based Hydrafeed is also a subcontract machinist for the aerospace, special purpose machinery and tobacco machinery sectors. To meet the machining demands of both sides of its business, the company has extensive machine shop capacity, ranging from manual machines through to CNC machining and turning centres. Sitting central to this capacity are four XYZ ProtoTrak-controlled machines.

Hydrafeed has been in operation for almost 50 years as a family-owned business with current managing director Martyn Page joining the company as a toolmaker 35 years ago. In 2012, along with his wife and son, he took the opportunity to buy Hydrafeed and maintain that family-owned tradition. Along the way, the barfeed element of the business has grown, with around one unit per day being dispatched. In addition, robotic automation for machine tools is now part of the Hydrafeed portfolio.
The company’s barfeed systems are sold mainly through OEM machine tool suppliers, such as XYZ Machine Tools. However, the resulting ongoing investment in machining capacity to meet the needs of barfeed production, meant that machines were sometimes underused. With this in mind, Hydrafeed expanded its operations to offer a subcontract machining service.
“Our subcontract work is tightly controlled and we manage the type of business we take on quite closely; focussing on regular customers with none of them dominating our capacity – the old 80/20 rule applies here,” explains Page. “Over the years we have continued to invest in machining technology, but like many, we have faced the skills challenge. Helping to overcome that are the four XYZ machines, which sit perfectly between our manual capacity and our CNC machining and turning centres. The ProtoTrak controls on the XYZ mills and lathes are straightforward to use and we have been very pleased with them. They are perfect for one-offs and smaller batch work.”

The XYZ machines installed at Hydrafeed are an SLX355 ProTurn lathe, an SLX 1630 ProTurn lathe and two SMX 2000 ProtoTrak turret mills. All four feature the ProtoTrak conversational control system, which is said to be notable for its ease of use. According to XYZ, operators who are new to CNC can be programming fairly complex parts with just a few hours of tuition.
On the SMX 2000 turret mill, the control is available as either a two- or three-axis system, with canned cycles to produce features such as various shaped pockets (including pockets with islands), thread milling, bolt-hole patterns, drilling, tapping and boring. ProtoTrak SMX also features its novel ‘guess’ button. If a dimension is missing from the drawing, the user can simply estimate the approximate position of a point or intersection, press the ‘guess’ button, and the control performs the calculation. Further advantages include 3D surfacing with on-board DNC, and the capability to handle virtually unlimited program size.
For its ProTurn lathes, XYZ uses the SLX variant of the ProtoTrak control, which also has many benefits in relation to ease of use. As with the mills, the control allows both manual and full CNC operation, with a key feature being the ‘Traking’ facility that is standard on all XYZ ProTurn lathes. Traking is one of a number of ways that the ProtoTrak control allows the verification of a program. Using this feature, the operator can work through the program using the two hand wheels. Traking can be used in such a way to go through the entire program or, up to a point where the operator is confident to stop the feature and press cycle start. Traking can be re-engaged at any time during the cycle. In addition to conversational, at-machine programming, which is said to allow even complex parts to be programmed in a matter of a few minutes, CAD drawings can be converted into programs using the optional on-board DXF file converter.

“Our sub-contract work continues to grow, and we occasionally need to call on others to help with over-capacity issues,” concludes Page. “This is where the value of our customer/supplier relationship with XYZ Machine Tools comes in. Talking with our XYZ area sales manager, he was able to point us in the direction of another XYZ customer, DJM Engineering, who had similar machines and skill sets to Hydrafeed, and this gave us the confidence to place work with them in the knowledge that they could maintain the delivery and quality which we expected. This is a great example of networking between businesses with similar work ethics to ourselves: being good at what we do and enjoying it at the same time.”

Edmo Group boosts productivity with mitre saw

The Edmo Group – specialists in aluminium extrusion profiles, aluminium fabrication and powder coatings – has recently purchased a Mecal SW453 Reverse double mitre saw from Addison Saws.

Edmo operates out of two locations – Ross-on-Wye and Wednesbury – and it was the need to further increase and improve upon its current mitring process that prompted the purchase of the new double mitre saw.
“The amount of mitring operations we have to apply are extensive,” states managing director David Ashton, “and looking at key ways in which we can improve that process, as well as increase productivity, is key for us as we look to further our impact on a competitive market. We were highly impressed with the capabilities of the Mecal and saw for ourselves how the machine handled complex operations, which in turn led us to make the purchase. In addition, we were very pleased with how smoothly the installation and commissioning of the Mecal proved to be.”
The Mecal is a double mitre saw with pneumatic positioned inward/outward tilting heads that offer a range of -22.5° to +135°, together with mechanical stops for intermediate angles. A large sector plate ensures accurate angle settings, with default positions set at 90° and 45°. The control system with graphical display and its USB data storage is easy to use for either quick random cuts or pre-programmed cuttings.
“Edmo’s strength lies in its ability to project manage complete turnkey supply solutions and, although it’s early days, we are confident that the Mecal will no doubt lead to increased productivity across our aluminium extrusion division,” says Ashton.

Automatic straight-cutting bandsaw released

Meba Saw has introduced the MEBAmat 330, an automatic straight-cutting bandsaw with 330 mm capacity. Available in the UK from ADS Precision, its carbide-compatible power package means the saw is designed for cutting solid bar, tubes and profiles, even from hardened, difficult-to-cut materials.

The saw runs continuously for single or multi-shift operations, whether operating two shifts, or unmanned three-shift operations. This fully enclosed saw is compact and practical. It saves space, has a larger machine door with a gas damper to keep it safely open, and allows easier access to faster blade changes and bandsaw maintenance. What’s more, Meba says that it does not sacrifice operator safety. The Plexiglas cut-outs allow safe observation and monitoring of the sawing process, while swarf and chips are prevented from exiting the machine envelope.
According to the company, a key feature of the saw is its ease of use. There is a material database in the controller which produces cutting values. With its search function, the material can be selected (length, width and other dimensions) before a saw blade and optimal cutting values are recommended. The operator can store cutting jobs with the saw’s memory function, while the machine can also import sawing programs from CAD.
The MEBAmat 330 is designed to offer solid, smooth, accurate cutting with its ball leadscrew feeding and latest linear ball guideways. Additional options include laser-monitored height detection and material width collision detection.
