An XYZ 1000 LR vertical machining centre from XYZ Machine Tools has been installed at Eclipse Magnetics, a manufacturer of magnetic chucks and lifting equipment, as well as magnetic filtration and separation systems.

A recent review of the company’s in-house machining capacity identified the need to replace an ageing vertical machining centre that had 25 years of service and was seen to be on “borrowed time”. Due to the nature of the work, with a mix of standard catalogue and bespoke systems, any new machine had to be versatile, easy to set-up and program, as well as provide the Y-axis travel needed to accommodate taller parts in the product range.
“In addition to the size of machine, the price/performance ratio was a major driver in our decision making when it came to the new machining centre,” says John Parker, design engineer at Eclipse Magnetics. “We looked at lots of options, but after discussions with one of our subcontractors, Impact Toolroom Services, who use XYZ machines, we settled on the XYZ 1000 LR vertical machining centre.”
The type of machining undertaken includes light milling, drilling and tapping in materials from stainless steel to aluminium, so the use of linear rail technology in the XYZ machining centre range provided the cost-effective solution Eclipse Magnetics sought. Choosing the XYZ 1000 LR also delivered the table size and Y-axis travel required, as well as the overall performance in terms of traverse rates and spindle speed, these being 20 m/min in all axes and 8000 rpm, respectively.

At the Leeds facility of the LoneStar Group, investment has been made in work-holding equipment that reduces job changeover times and increases production efficiencies.

LoneStar Leeds specialises in the manufacture of products such as valve gates, stems, seats and metallic seals for the oil and gas, petrochemical, power generation, and renewable energy markets. The facility houses 13 machining centres, consisting of vertical, horizontal and twin-pallet machines with capacities up to 2,300 by 800 mm.
The managing director at LoneStar Leeds, Jon Collinge, says: “Having invited Thame Workholding to visit our site and assess a series of soon-to-be-manufactured thin walled parts with challenging specifications, the InoTop jaw system was recommended. The system proved to be ideal for securely holding the parts without causing deformation or compromising roundness. In addition, the use of InoTop accelerated production in this potentially problematic area. Given the elimination of scrap and the significant time savings we now achieve, our InoTop jaw system is ahead of schedule on its projected ROI.”
Operating on the principle of centring the workpiece on its outside diameter without the application of pressure, then clamping from the inside diameter, InoTop prevents unwanted polygon formations in the clamping process.
“The great success of the InoTop jaw system means that we have since invited Thame to look at several of our other machine tool applications,” says Collinge. “Their recommendations and our subsequent purchases of additional Thame Workholding products have enabled us to achieve further efficiencies and helped us to uphold our demanding quality standards.”

When Tecomet, a manufacturer of products and services for the medical device, aerospace and defence sectors, needed a secure and flexible work-holding solution for its machine shop, the company turned to Hainbuch and its Manok stationary clamping system.

At the company’s Sheffield facility, where component precision, quality and surface finishes are critical, Hainbuch provided the most suitable and flexible solution. Tecomet’s first investment in Hainbuch equipment was the 65 mm Manok stationary chuck for its DMG DMU 50 machining centre.
Product manager Stephen Jackson says: “What we used to do here is hold the job in a two-jaw chuck, but this gave us a lot of issues with vibration and positional accuracy. So, we opted for the Manok 65 from Hainbuch and it solved our issues. The positional accuracy is spot-on and there are no more scratches or issues with surface finish. Furthermore, it’s saved a lot of reworking and secondary finishing.
“The rigidity of the Manok has improved our tool life dramatically and reduced our tooling costs,” he continues. “Furthermore, we’ve been able to push the tools harder and run the machines faster than before, and this has improved our cycle times while reducing tool consumption. On a particular femoral knee job, we’re looking to maintain a precision level of ±10 µm. One key point is that we have numerous five-axis machine tools on-site and we can interchange the Hainbuch system, easily placing it on another machine if necessary. It’s simple, quick and easy to use, and the support from Hainbuch has been very good.”
Following the success of the Manok, Tecomet purchased a pneumatic fixture plate with six Hydrok 42mm collet chucks from Hainbuch.

The Vero-S NSE-A3 138 automation module from Schunk is specifically for automated machine-tool loading, as well as applications in handling, assembly and automation technology.

For process-reliable workpiece and clamping device changes, the automation component is equipped with a blow-off function, which cleans the interface surface during changeover. In addition, a spring-actuated cone seal prevents chips or dirt from penetrating the interface.
Pull-down force of 8,000 N or 28,000 N, along with activated turbo function and high dimensional stability of the module body, benefit the rigidity of automated quick-change solutions. Thus, even high tilting moments and shear forces can be reliably absorbed. Depending on the application, the modules can be combined in any quantity.
Centring inserts featuring flexible elements ensure positional orientation with a high repeat accuracy (<0.005 mm) and process reliability in automated operations, says Schunk. Due to the conical fitting, the clamping pins can also be joined into the modules eccentrically, simplifying the process. The actual clamping is done without any external energy supply via spring force; it is form-fit and self-retaining. This design attribute means that workpieces remain safely clamped in the case of a sudden drop in pneumatic pressure. A pneumatic system pressure of 6 bar is enough to open the module. When the modules are used individually, a standard, integrated, anti-twist protection device ensures a stable position. By means of the integrated media transfer unit, fluids with permissible system pressures of up to 300 bar can be transferred. As a part of the Vero-S modular system, the automation module benefits from a variety of combination options, from standard plates to Schunk Tandem clamping-force blocks, to mechanical vices from the company’s Kontec series.

New to the UK from RARUK Automation are two Robotiq innovations designed to make automated, and even lights-out production, easier.

The first, Force Copilot, is an intuitive software development for applications that need force torque feedback, while the other is the Hand-E gripper, which is designed specifically for collaborative robots.
Sensing functions on the Robotiq Force Copilot increase flexibility and reliability in machine-tending, assembly, finishing, and pick and place applications. A suite of set-up tools allows the user to hand-guide the robot on complex trajectories. The software makes it easy to place objects precisely in jigs, trays and chucks, and facilitates assembly applications through alignment, indexing and insertion functions. Finally, the intuitive interface unlocks finishing applications, with adjustable adaptive compliance and constant force for all robot axes.
Robotiq’s Force Copilot is now a standard feature of the FT 300 force torque sensor that can be seamlessly integrated into the second of the additions to the RARUK Automation range: the Robotiq Hand-E gripper. With its compact and ergonomic shape, the Hand-E gripper is said to make collaborative robot hand-guiding safe and easy.
This latest product in RARUK Automation’s line-up of adaptive grippers, is the first UR+ electric gripper to be developed that takes full advantage of the Universal Robot e-Series. High accuracy and 50 mm parallel stroke make the Hand-E gripper suitable for precision assembly tasks, while its sealed design ensures reliability in tough manufacturing conditions. Hand-E gripper comes with a three-fingertip kit, so automation engineers can easily integrate the gripper in their application.
