Dugard has strengthened its portfolio of turning centres with the arrival of the Pinacho brand of conventional and CNC flat-bed lathes. Dugard will be aiming to sell the SE series of user-friendly intuitive CNC lathes, the ST series of precision flat-bed lathes and the SH series for heavy-duty roughing.

Dugard sales director Colin Thomson says: “The Pinacho brand has more than 70 years of pedigree in building high-quality machine tools. With the company manufacturing its machines in the Basque region of Spain, an area synonymous with many of the world’s leading machine tool brands, we’re delighted to bring such a prestigious name into the Dugard portfolio. The Pinacho range will complement our existing offering of turning centres, which ranges from the compact Hanwha sliding-head turning centres through to the robust SMEC range.”

Leicester-based JWA Tooling has recently invested more than £2.5m in an additional factory, three new FANUC EDM machines, three new automation-ready Mazak machining centres, a Doosan Lynx turning centre and a Colchester Harrison Alpha 1400XC lathe. The link that is increasingly tying these machines together is work holding and clamping technology from Hainbuch.

Says company founder John Wood: “If you analysed our company, you’d see that we have lots of machines and lots of set-up time, which means the machines can be stopped for longer than they are running. We have chosen to address this issue by investing in new work-holding systems.”

For instance, when JWA Tooling invested in a Colchester Harrison Alpha 1400XC manual and semi-CNC turning centre, the decision to invest in a Hainbuch Torok 65 manual chuck was influenced by the ability of the chuck to offer fast and precise changeovers. The flexibility of the Hainbuch Torok 65 also permits fast changeover from ID clamping to the OD jaw clamping of components.

More recently, when the company decided to install a Doosan Lynx 2100LY turning centre, the subcontract manufacturer once again opted for work-holding technology from Hainbuch with the Top Plus 65 combi pull-back collet chuck.

“The reason for picking this particular design of chuck is quite critical, as we have been well established with round collets over the years,” says Wood. “However, if you look at modern machines with live tooling and C-axis configurations, you need to index accurately and know where the component faces and locations are. So, with the Hainbuch system and its hexagonal fitting, you can identify your mark on the chuck and the collet and put the collet back in the identical position.”

A new, high-precision, electrically actuated vice for securing workpieces on vertical, horizontal, five-axis and mill-turn machining centres is now available from Roemheld UK. It is possible to integrate the operating functions of the Hilma AS 125 E into the machine’s CNC system or regulate them via a separate control.

The Industry 4.0-compatible vice is equipped for automatic jaw change, making it suitable for unattended machining involving the robotic loading and unloading of components, as is often found in series production environments. Users can manufacture entire families of parts without manual intervention.

Roemheld’s AS 125 E lowers operating costs by eliminating the need for hydraulics or pneumatics, and by retaining the holding force without the power supply connected thanks to the self-locking mechanical spindle. The motor precisely adjusts the tightening torque, so the holding of thin-walled components and other delicate workpieces can take place without damage. The vice is also suitable for applications where the risk of contamination by hydraulic oil must be avoided.

Guido Born, the product manager in Germany responsible for the launch, says: “Beta tests in production applications have shown that the electric vice lends itself well to the accurate retention of parts, as the pressure may be finely controlled to suit the workpiece material and geometry.

“The automatic jaw change has been particularly impressive,” he adds. “One user told us that the system paid for itself quickly and plans further investments. Electromechanical designs are now being developed for other proven clamping systems in the Roemheld range and will be released in the near future. Additionally, we are planning further innovations such as using sensors in our hydraulic work-holding systems to help determine clamping force.”
