Cut unit costs with workpiece holders and baskets designed for optimum cleaning

29 01 2016

These days, defined cleanliness specifications are common in component production across virtually all sectors. To comply with these specifications, some companies are investing vast sums in systems engineering and process technology. However, one major factor is often not considered: the cleaning basket. This is very critical as the cleaning basket influences effectiveness of the costly process technology significantly, and thus the costs of cleaning.

By the optimum positioning of components in the workpieces holder critical areas such as specific bore holes and undercuts can be treated specifically.

In most cases, adapting or optimising a cleaning process revolves around systems engineering, process technology and the cleaning media. What tends to be forgotten is that process technology such as ultrasonics, spray jets and cleaning media may only work to best effect on parts to be cleaned when they can reach those parts properly – and it is the cleaning basket used that determines the level of effectiveness. Incorporating baskets and workpiece holders into the considerations at an early stage is therefore worthwhile.

Accessibility from every angle
The optimum cleaning effect is achieved where the workpieces in the basket are easily accessible from all sides for the process technology and the media. To facilitate this, Metallform produces workpiece holders and baskets for bulk parts from stainless steel rounds. In contrast to boxes from perforated sheets that are still often used, these baskets have no enclosed surfaces, corners and edges. Therefore, ultrasonics and spray jets have unfettered access to parts and can take maximum effect. At the same time, the open design ensures an effective exchange of media. On the one hand, removed contaminant is flushed from the basket quickly and can be removed by the filter and the accumulation of contamination in the basket is inhibited. On the other hand, the carry-over of cleaning media is minimised, resulting in longer periods between bath changes and thus improved system availability. In addition an open basket design allows cost savings in the drying process, as the easy accessibility of parts reduces the drying time required.

Optimum adjustment of workpiece holders to parts
Early integration of cleaning baskets also enables these to be adapted effectively to the cleaning machine and the workpieces to be cleaned. One consideration in this context is the optimum positioning of components in the workpiece holder. To achieve this, Metallform uses CAD technology. The optimum positioning of components enables the process technology being used to access critical areas such as specific bore holes and undercuts. In this way, particles and film-like contamination are quickly and reliably removed and the effective, resource-efficient drying of parts is assured. Another design feature is the minimising of contact points between the component and the workpiece holder. This also helps to ensure cleaning of consistent quality within a short time.

Stainless steel for long lifetime and maximum security
Metallform produces all workpiece holders and baskets from stainless steel rounds with electrolytic polished surfaces. With good reason: This high quality, durable material is suitable for all cleaning media and prevents components from being recontaminated by the workpiece holder and baths from being contaminated by corrosion and zinc separation. Aside from the design and material, the workmanship of the cleaning baskets is equally convincing. All joints are completely welded and there are no sharp corners, edges or wire ends that could cause injury.
A basket designed for optimum cleaning may not improve the cleaning machine, but it ensures that process technology (which is generally expensive) can work to maximum effect.

BIG KAISER lightweight angle head increases accuracy and productivity

21 01 2016

BIG KAISER, a leader in premium high-precision tooling systems and solutions for the aerospace, automotive, energy, medical and watch-making industries, today announced the AG90 Light Weight Type with BT30 (BIG-PLUS) taper, a fixed 90-degree angle head.

blogBIGKAISER-Angel-head-Lightweight-type---Cutter-head-adjustable-360-(1)

Angle head lightweight type, cutter haed adjustable 360

Part of the BIG KAISER family of angle heads, new AG90 Light Weight Type weighs less than 2kg. This makes it one of the lightest angle heads in the world, and it is therefore compatible with the automatic tool change of small machines.

By allowing vertical, horizontal and angular operations without repositioning the workpiece, BIG KAISER angle heads increase accuracy and productivity. Being able to use just a single set-up, and to easily change the angle of the cutter over a 360 degree range, speeds up production and eliminates errors due to multiple set-ups.

Angle heads enable users to benefit from new capabilities without replacing their current machining center, saving the cost of a new machine.

“The new AG90 combines advanced design features and high quality components, while keeping its weight down to the absolute minimum,” says Peter Elmer, CEO of BIG KAISER. “It complements our existing range of angle heads, which enable customers to find the right solution for almost any application.”

The AG90’s compact design minimizes overhang, which adds rigidity and strength. The minimized overhang also helps to eliminate interference with the ATC and adjacent storage pockets in the tool magazine.

An advanced non-contact seal prevents coolant and particle contamination better than other sealing methods. A unique coolant jacket efficiently directs coolant coming through the stop block to the tool cutting edge, while simultaneously cooling the angle head.

To minimize noise and vibration, the AG90 is made from superior quality components, including hardened and ground chrome-nickel steel spiral bevel gears, super precision hardened and ground spindles, and high precision angular contact ball bearings.

BIG KAISER provides many different types of angle heads such as the AG90 family for milling and drilling or the AGU30 with adjustable angle. In addition, numerous special options can be ordered, and the angle head is available in a wide range of tapers, lengths and designs.

Delcam adds robot for additive manufacturing research

18 01 2016

Delcam has added an ABB robot fitted with a Fronius CMT Advanced welding head to the range of manufacturing equipment at its Birmingham site. The new unit will be used mainly for research into the programming of robots for the additive manufacturing of metals with Delcam’s PowerMILL Robot software.

BlogAdditive-robot

The ABB robot at Delcam will be used for research into metal additive manufacturing.

Cold Metal Transfer welding was initially developed by Fronius to join materials with different properties, in particular for welding aluminium to steel. The process uses very high frequency movement of the wire to give a clean, spatter-free material transfer. It provides a stable, reproducible deposition of material that Delcam believes should have great potential in metal additive manufacturing.

The ABB robot arm offers six axes of movement, with an additional two axes, tilt and rotation, provide by the table holding the material. This additional flexibility allows parts to be oriented into the optimum position as they are being built so enabling complex shapes to be created with less need for extra support structures.

PowerMILL Robot makes it as easy to program a robot for machining as it is to program a five-axis machine tool. As a fully-associated application inside PowerMILL, users have access to all the multi-axis machining strategies within PowerMILL and can use all the system’s project management options to manage, store and retrieve data.

As well as making it possible to program robots for additive manufacturing, PowerMILL Robot can be used for tool-to-part applications, especially for machining large parts, such as composite panels that need to be trimmed, or for part-to-tool applications, such as grinding or polishing.

Schuler opens Hot Stamping TechCenter

15 01 2016

Schuler today opened its new research and demonstration center for hot stamping at its home base in Göppingen, Germany. At the so-called Hot Stamping TechCenter, the company will be showing its customers innovative applications for the future of lightweight vehicle construction. Schuler has invested some 6.5 million euros in the line, which is equipped with hydraulic press, roller hearth furnace, and automation. It was developed at the company’s Waghäusel site.

blog2016_01_14_hot_stamping4

In the hot stamping (or press hardening) method, sheet steel is heated to 930 degrees Celsius, and cooled and thus hardened in the subsequent forming process. This enables the production of extremely light but highly rigid vehicle parts. Schuler is the global market leader for hot stamping equipment. Due to the growing requirements for passenger protection and the need to reduce CO2 emissions, demand is expected to grow in the coming years.

“Hot stamping is an important method for producing lightweight car bodies and plays an important role in Schuler’s product spectrum,” stated CEO Stefan Klebert. “Our new Hot Stamping TechCenter is proof of both our innovative strength in the field of fully automatic, networked production lines and of our firm commitment to Germany as a high-tech manufacturing location.”

Increased productivity and decreased energy consumption
The 1,600-metric-ton press at the Hot Stamping TechCenter already boasts Schuler’s PCHflex technology. “PCHflex allows a flexible and economical production of hot stamped parts with up to 40 percent higher output performance and consistently high quality, combined with maximum process reliability and availability,” explained Dr. Martin Habert, Managing Director of Schuler in Waghäusel.

The press line is also equipped with EHF technology (Efficient Hydraulic Forming), which drastically reduces energy consumption. Thanks to its condition monitoring system, the wear and tear of machine components can be precisely anticipated.

First line in Schuler’s new machine design
The press line is also the first to feature Schuler’s new machine design, which the company will gradually roll out across its entire product range. The new design aims to symbolize Schuler’s technological lead and ensures a high degree of recognition.

The Hot Stamping TechCenter will mainly be used for the ongoing development of machine technology and lightweight vehicle construction processes. However, Schuler also plans to use the center for customer presentations and training.

Apart from Göppingen, Schuler also has demonstration and reference centers at its German sites in Erfurt, Gemmingen, Göppingen and Hessdorf, as well as in the USA. In contrast to trade shows, TechCenters are open all year round and enable customers to receive individual support and run their own tests. In spring 2016, a further TechCenter will go into operation in the North Chinese coastal city of Tianjin. It will feature a 1,600-metric-ton press with TwinServo Technology (TST).

3rd Edition of the 3D Printing Materials Conference

8 01 2016

On January 26-27, 2016, the 3rd Edition of the 3D Printing Materials Conference will take place at MECC Maastricht, in The Netherlands.

Logo-Materials

Insights from speakers’ presentations at the conference:

  • Theo Salet, Professor, Technical University of Eindhoven, about “3D Printing of Sustainable Concrete Structures – From a Black and White Printer towards a Colour Printer”: “Printing of concrete structures saves on the costs, improves productivity and could above all seriously limit the environmental impact. This lecture explains the digital design of printed concrete structures, using evolutionary tools to minimize the amount of material needed. It also shows the development of a large scale concrete printer, able to print different types of concrete at the same time amongst structural – and innovative insulating types of concrete.”
  • Tristan Mes, Manager, SupraPolix, about “3D-Printing of Self-Healing Supramolecular Materials”: “Supramolecular polymers, based on hydrogen bonding are eminently suitable for FDM 3D-printing. The thermo-reversible nature of hydrogen bonding favors the interplay between the intrinsic processability and the mechanical properties of the polymer and is therefore lowering its printing-temperature while retaining its mechanical performance. Furthermore, the specific rheological profiles of supramolecular polymers may lead to unique dynamical properties like self-healing behavior.”
  • Stijn Lambrechts, Business Development & Innovation Additive Manufacturing, SIRRIS, about “Guide to optimize print parameters for an LBM process”: “If we want additive manufacturing to become more cost effective, one key enabler will be to open up the market for material supply to AM. For quality and process stability reasons, many suppliers of AM machines try to organize the material supply for their machines by sourcing the materials and distributing them to the machine users. For powder bed AM machines however, supply of suited powders is broadly available on the market at more cost effective prices.”
  • Johannes Overvelde, Harvard University, about “Embracing compliance in robots to achieve function”: “In coming years, the fast developing field of 3D printing will likely result in completely soft robots that do not require any assembly.”
