THIS WEEK’S HIGHLIGHTS

Mazak launches laser automation cell

Yamazaki Mazak unveiled its latest laser automation cell at Blechexpo in Stuttgart last week. The OPTIPLEX 3015 DDL 4.0 kW laser processing machine features Direct Diode Laser technology unique to Mazak, complete with a new robotic automation system. Those requiring ultra-fast cutting and high-quality edges are set to benefit most.

According to Mazak, the OPTIPLEX DDL series can cut thin material 20% faster than fibre lasers, and thick materials with high surface quality. The machine has an axis acceleration of 1.8 G and benefits from rapid traverse rates of 120 m/min. Positioning accuracy is maintained to within ±0.05 mm per 500 mm in the X and Y axes, and to within ±0.01 mm per 100mm in the Z axis. The machine also offers repeatability accuracy of ±0.03 mm in the X, Y and Z axes.
Crucially, the OPTIPLEX DDL is a machine capable of a wall plug efficiency of 40-50%, compared with 10% for a CO2 resonator, 15-20% for a disc resonator and 30-40% with a fibre resonator.
At Blechexpo, the machine on display was shown as part of a new automation cell that incorporates a robotic arm mounted to rails adjacent to the cutting table, to load and unload workpieces. The arm can quickly change between sorting tools – which are mounted directly to the robot’s base – depending on application and the size and weight of the workpiece. To deliver fast and accurate machining, the cell’s laser table is equipped with an automatic clamp to secure the workpiece’s position on the table. This is especially useful for cutting thin vinyl-protected material.

Best ever EMO for Walter Ewag

Walter Ewag UK is reporting the “best ever EMO” after orders valued at more than €30m were placed at the show for Walter and Ewag tool grinders/eroders, and Walter tool measurement machines. The record order intake for more than 100 machines does not include orders taken for the other United Grinding Group brands exhibited.

Included in the host of new developments and machines shown at EMO by Walter was the Helitronic Vision Diamond 400L two-in-one tool grinding and erosion machine – for PCD, carbide, HSS, ceramic, cermet and CBN tools from 3 to 315 mm diameter and up to 420 mm long – and the Heliset Plus manual measuring device which is said to help optimise the erosion (machining) times of complex tools by up to 30%. Ewag’s display included the new six-axis Ewag Compact Line for the grinding (including peripheral grinding) of inserts in tungsten carbide, cermet, ceramic, PCBN and PCD.

Workholding system improves productivity

When Chick Workholding launched its One-Lok clamping system seven years ago as an alternative to the conventional machine vice, the company made available more precise workpiece positioning and a time-saving ratchet mechanism to adjust the position of the moveable jaw quickly. New lightweight versions have now been unveiled, offering users additional benefits. Availability in the UK is through sole agent 1st Machine Tool Accessories.

The latest One-Lok comes in two sizes rather than one, 400 or 500 mm long, offering maximum gripping lengths of 180 and 280 mm respectively. Further improvements include a lowering of the clamp profile from 150 to 134 mm, which allows longer spindle travel in the Z axis and halves the unit’s weight for easier handling. With this in mind, an ergonomic hand grip has also been added at either end.
Sometimes, machinists turn a vice through 90° so that it lies transversely across the machine table. This strategy can bring the part closer to the operator, but has the disadvantage that there is no clearance for the handle. With the new One-Lok, workholding in this orientation has been made easier by using a ratchet handle.
The moveable jaw on One-Lok systems can be adjusted quickly and conveniently, as it can now be slid using one hand rather than two over the QwikSlide ratchets. A few turns of the handle move the jaw in the same direction over the last few millimetres to complete the clamping action. The existing BoltFast interface for the 152mm wide, interchangeable hard and stepped steel jaws and aluminium soft jaws, has been retained. A quarter turn of the locking screw is all that is required to exchange them, promoting productivity when machining small batches of components.

ETG taps into girl power

A UK machine tool supplier is benefitting from ‘girl power’ after its newest technical co-ordinator marked a major milestone. Chloe Reeve, 23, has just completed her 25th training course for Engineering Technology Group (ETG) clients, just four years after joining the business as an apprentice. She has played a key role in the firm’s roll-out of its Technical Academy Network and her latest course involved putting three employees from tool manufacturer Guhring through their paces on the new Hardinge Bridgeport XR760.

“2017 has been a great year for me and I’m really enjoying the new role, where I’m interacting a lot more with customers to make sure they receive the right technical advice and training on some of the new technology we are supplying,” she says. “During my own development, I’ve learned a variety of different CNC Programming languages, including Fanuc Turn and Mill, Siemens ShopTurn, Shop Mill and Heidenhain’s 530, 620 and 640 controls.”

Open Mind expands UK team

Open Mind Technologies, which last year posted record sales figures, has employed three new staff to help underpin the CAM software specialist’s growth levels. Karl Oram has joined after spending 25 years as a CADCAM specialist in Canada. Appointed as an application engineer, he will apply his experience to conducting demonstrations, on-site support and training for end users. In support, Joshua Harper and Cory Jamieson have also joined Open Mind, as application engineer and junior application engineer respectively.

Adrian Smith, managing director at Open Mind Technologies UK, says: “To underpin our continual growth, we have a strategy in place to employ more sales engineers and application engineers. It is the application engineers that will support new customers beyond the post-sales process with assistance for all technical queries. Our new recruits will enhance customer experience and service while supporting the sales engineers.”
