Alprobotic delivers first resist-mask-free sanding and microbead polishing unit for dental implant surface finishing

Alprobotic, the global expert in surface finishing processes for high-added-value parts, announced today that it delivered a completely robotic resist-mask-free microbead polishing unit to Spanish dental-implant market leader Klockner Implant System.


Each day, the Alprobotic unit will process 50 different products for total throughput of 1,000 implants per day. The unit was designed to meet the medical industry’s particularly stringent biocompatibility, repeatability, and quality requirements.

Klockner Implant System chose the Alprobotic microbead unit for its unique capacity to support a resist-mask-free process. Previously, Klockner Implant System manufacturing processes included making resist masks to protect the implant flange; human operators had to position and remove the masks. The Alprobotic unit eliminates these steps, substantially reducing sand consumption. ROI is expected within two-and-a-half years.

A repeatable, programmable process
Alprobotic’s precision unit ensures optimal surface-roughness (Ra) consistency and a level of quality that far exceeds what can be achieved using manual processes. The unit is also easy to program, for total control of sanding distance from nozzle, pressure, impact speed, and particle trajectory. The robotic unit automatically changes tools when switching from one type of implant to another.

Comprehensive production-order management
The resist-mask-free sanding unit is compatible with 24/7 plant operations, offering total throughput of 1,600 implants per day. It can also be integrated with quality control, laser marking, and anodizing processes and can handle the various stages of the qualification process (IQ, OQ, and PQ). Additionally, the unit can export end-of-production-order data, for seamless integration into fully-computerized plants.

Medical industry accounts for 80% of Alprobotic’s business
The medical industry—mainly orthopedic, spinal, and dental implant manufacturers—accounts for 80% of Alprobotic’s revenue, with customers around the globe. Alprobotic is currently in advanced-stage negotiations with manufacturers in Switzerland and Germany for turnkey spinal implant finishing shop projects.

AMB 2016: Robots on the rise

Expert interview with Professor Dr.-Ing. Thomas Bauernhansl / Robotics and automation technology on the rise

Robots are taking the production halls by storm and are being integrated in machine tools and automation systems to create plug-and-play modules. The increasing networking and platform connection leads to completely new control architectures. In brief: The world of machine tools is experiencing dramatic development. This will trigger plenty of discussion between exhibitors and visitors at AMB, the international exhibition for metal working, which takes place in Stuttgart from 13 to 17 September. Professor Dr.-Ing. Thomas Bauernhansl, Director of the Institute of Industrial Manufacturing and Management (IFF) at Universität Stuttgart, as well as the Fraunhofer Institute for Manufacturing Engineering and Automation (IPA), encourages people to take the developments seriously and discuss them in an opportunistic manner.


Professor Bauernhansl, robots are taking the production halls by storm. Are robots becoming competitors to machine tools?
A robot still cannot replace the machine tool. The robot can only assume non-core processes of the machine. Examples include handling activities, or supporting and accompanying the employee who operates the machine. Typical tasks are deburring, positioning or changing workpieces. But the robot will not do the actual machining or metal cutting, because it doesn’t possess the required accuracy or dynamics. In the future, however, the transition between machine tool and portal robot could become more fluid. Its flexibility and the extremely advanced possibilities of programming speak in favour of robots. The machine tool is increasingly converging with the robot, they no longer stand side by side as separate components.

How is automation technology in the field of machine tools generally developing?
We are noticing that the machine tool competence among automation manufacturers is increasing. They are optimising the layout and system design. The topic of flexibility plays a huge role, i.e. the question of scalability from manual to semi-automated to fully automated and vice-versa. This restricts the integrative approach again somewhat. Components of machine tools must be able to be replaced quickly. For instance, integrating robots or palletising systems quickly and also removing them again. It is not only about versatility and adaptability, but also about efficiency, i.e. the topic of plug-and-produce by the machine operator.

The control technology also has to be adapted. What changes will we experience here?
The classic control technology of the machine tool is heading towards plug-and-produce. Hard-wired hardware-based NC systems no longer have a future. For plug-and-produce the respective components need to be more intelligent, i.e. in the robot arm, gripper, spindle, feed conveyor, etc. These autonomous systems have their own microcontrollers and register on a platform via an interface. They communicate what services they provide, and the employee at the machine can then configure it to a smart workflow. With the ever-increasing bandwidth and latency of the networks, one can outsource services from the machine tool and offer them, for example, on cloud-based platforms. In the end only a few tasks such as security are still performed locally. Functionality as a service is a big trend.

How does automation technology deal with diverse requirements due on the one hand to mass production, and on the other to increasing individualisation of the products?
There will always be mass production, but increasingly the customised product, which is adapted to the individual needs of the customer. The automation of mass production is very advanced. Here it is not only about making the processes more robust through the clever use of data and retrieving the very last percentage. In contrast, customisation demands a high degree of flexibility, i.e. the ability to convert within seconds or even during the process. These topics require a different type of automation technology with corresponding adaptability and versatility, perhaps in the future the ability of independent optimisation in communication with the component.

A question which will also be discussed with great controversy at AMB: Where is Germany on an international comparison?
This topic is gaining considerable momentum in the USA, Japan, Korea and now also in China. In Germany we need to take this development seriously and deal with the issue intensively. The surveys are alarming, on the one hand 80 to 90 percent of companies state they are affected by the development, but only between ten and 20 percent of these companies are giving serious thought to the matter. We have to do more, become more determined and more companies have to get involved in the development. Above all we need to discuss the matter in an opportunistic manner and not only analyse the risks.

Robots at AMB
The manufacturers ABB Automation (Stand 5D32), Erowa System Technologies (Stand 7C77), Fanuc Germany (Stand 7B51), Kuka Roboter (Stand 8A69) and Mitsubishi Electric Europe (Stand 5D74) present their latest generations of robots at AMB in Stuttgart. Over 30 exhibitors showcase handling and automation solutions with robotics.

Robotised finishing center

Well known for its multifunctional machining centers (rotary transfer machines), Precitrame Machines SA is also a historical provider of high performance polishing machines. The company has just presented a concept of robotic linear transfer machining centers with features that open new perspectives in terms of finishing and polishing. Meeting with Mr. Vincenzo Bonavoglia, Sales Director of the company.

Under a relatively small footprint, the Cyberpolish 640 T can offer up to 5 online cells offering two workstations each. It is controlled through the new Cybermotion 5.0 that offers features never seen before as the high performance trajectory following and the simultaneous management of six robots.
Under a relatively small footprint, the Cyberpolish 640 T can offer up to 5 online cells with two workstations each. It is controlled through the new Cybermotion 5.0 that offers features never seen before as the high performance trajectory following and the simultaneous management of six robots.

The basic concept is simple, let’s imagine a working cell including a robot and two workstations allowing six or seven axes machining. Then let’s multiply these cells to create machines with two to five stations. Parts are gripped in holding devices that move from one station to the next. Thus, it is possible to implement a global chain of finishing (e.g. deburring, felting, polishing and brightening) within a single machine, and in one clamping.

Incomparable cycle time and flexibility
The logic of the sequential work on several stations (and therefore always with operations in hidden time) allows the achievement of extremely short cycle times. Compared with a conventional solution, the tests show gains of 5 times or more.

To gain steps of production?
Nowadays the quality produced by machining centers is steadily increasing and, depending on the part to be done, they can be directly loaded into the Cyberpolish T for all operations from grinding to brightening without having to pass through a specific grinding machine before. M. Bonavoglia says: “In some cases, specialised grinding operations before finishing are always necessary, but for all the others, we can directly finish the parts in one machine and in one clamping just after the milling operations”.

Precitrame will be present at the next AMB with a multifunctional machining centre that will perform an automotive part. The new Cyberpolish series T will be shown through the many multimedia tools of the company.

The world’s first lightweight industrial robot at EPHJ/EPMT/SMT

LBR iiwa – intelligent industrial work assistant – is KUKA’s new lightweight robot. Equipped with industrial duty mechanics and drive systems, it is sensitive, yielding, precise, flexible and can be used to automate delicate, complex assembly tasks that were beyond the capabilities of robots to date.
Kuka LBR iiwa
Design based on the human arm
LBR iiwa has seven axes and was designed to replicate a human arm. It can be operated in position and yield control mode, and thanks to integrated sensors, the robot’s sensitivity is configurable. LBR iiwa was made for delicate joining processes, and the robot can even handle simple tools thanks to built-in high-performance collision detection algorithms and torque sensors integrated into the joints of each axis. Low weight, seven axes and a slim profile make the robot ideal for tight spaces and easy to integrate into manufacturing lines. LBR iiwa is designed to handle payloads up to seven or fourteen kilograms, making KUKA the first and only company to offer a lightweight robot capable of handling payloads over ten kilograms.

To be discovered
LBR iiwa opens a new chapter in the book of human-machine cooperation. Acting as an operator’s “third hand”, it opens the door to completely new applications in which safety barriers are a thing of the past. Visitors to EPHJ/EPMT/SMT will be able to judge for themselves when they examine solutions at KUKA’s booth. Each of the displays demonstrates LBR iiwa’s unique features.

The company will also shows a KR Agilus robot perfectly tailored to the sector of production in microtechnology.

To be discovered on the C100 booth in Geneva from June 17 to 24, 2014.

Opportunity celebrates 10 years on Mars

Ten years ago, the NASA rovers Opportunity and Spirit landed on Mars. It keeps going and going and going. “It is equipped with maxon brushed DC motors” the company proudly announced recently.

Today, Opportunity is still exploring Mars – an unbelievably long time, considering the robot was only designed to last about 90 days. It has covered a distance of approximately 39 kilometers so far and continues to roam around a vast area. On board, 39 maxon brushed DC motors can be found.

On January 25, 2004, the Mars rover Opportunity landed in the Eagle crater. Since then, it has been investigating the planet for NASA (National Aeronautics and Space Administration), a USA agency responsible for the exploration of space. It has examined a number of craters, dunes, and flats, always searching for traces of water. It did not take long before Opportunity found first indications (sediment structures, minerals) that there used to be water on Mars. The Mars rover is able to take photos, brush the ground and drill into stone and it continues to do so today. “The rover is in exceptionally good condition for its age”, says John Callas, a manager at NASA. However, things haven’t always been easy for the rover in the past ten years. Its wheels have become stuck in the sand requiring a very difficult maneuver to release them once again. Sand storms disabled the solar panels and prevented the batteries from recharging. Opportunity is now starting to show a few small symptoms of aging: the 185 kg robot has a bit of “memory loss” – every now and again, its hard disk shows signs of wear caused by the long period of use.

39 km and 39 maxon drives
With drives manufactured by maxon motor, Opportunity has been able to safely navigate the surface of Mars for ten years. The rover contains a total of 39 brushed DC motors that are all still operating reliably. They are used to drive the robotic arm, the Rock Abrasion Tool (RAT), the cameras, the control mechanism and the wheels of the rover. The motors are standard products with diameters of 20 to 25 millimeters and an efficiency of over 90 percent. Minor modifications were necessary to adapt the DC motors for the harsh environmental conditions: the temperature on the surface of Mars fluctuates between approximately -120 °C and +25 °C.

This speaks about reliability of maxon motors (as well as all other pieces of equipment on the robot) indeed, but also about human genius. We at Eurotec haven’t thought to use Opportunity to spread the microtechnology messages of our customers to the red planet!

The RE 25 and RE 20 DC brushed motors from maxon motor have been working on Mars for an entire decade.

Shuttle tool changer to be discovered at EMO

Colombo Filippetti, the Italian company from Torino, will unveil a new optimized shuttle tool changer simplifying operations and management at EMO on hall 26, Stand F07.
The main characteristic is that no hydraulic device is used, this allows impressive results. Compared to the usual devices, the system is noiseless, cleaner and  much more reliable. It is composed of an exchanging unit assembled on a shuttle moved by a servomotor which slides, through rollers, on a hardened prismatic guide.

Vertical and horizontal
The exchange cycle (180° rotation) is completed by using a precision reduction gear with servomotor while the cone extraction stroke is operated by an oleo-pneumatic cylinder. In the version (O+V) it can change the tool with spindle both in vertical and in horizontal positions: in this version the tool exchanger is pivoted in a fulcrum and can rotate by 90 degrees operated by an oleo-pneumatic cylinder. The gripper arm has a mechanical control with shutters when the tool is drawn from the spindle.

Tailored to customers’ needs
The CTNE 50 is completed by different kinds of ring or annular magazines with a number of tools variable from 20 to 80 tools according to production needs. It fits to the following types of cones: ISO 45, ISO 50, BT 50, HSK 80, HSK 100, Capto C8 and Capto C10 with tool weight of 25 kg in the standard version and  35 kg in the heavy version (W). Colombo Filippetti will show some of its more significant products at EMO. It will also be possible to see the different applications of the CTNE 50 on some of its customer’s machines on show at EMO.
