• NUM partners with Taiwanese specialist for hydrostatic grinding machines GRINTIMATE (Jul 14, 2023)

  07/05/2023 – Teufen, CH

  GRINTIMATE is a specialist in the Asian market for hydrostatic grinding machines. Like NUM the company founded in 2015 is based in Taichung. The company has gained a name primarily for its hydrostatic cylindrical grinding machines, rotary surface grinding machines and wafer grinders.

  How it came to cooperation

  Adrian Kiener, NUM CSO for Asia, got to know GRINTIMATE back in 2018 at the CIMT (China International Tool Show). Since then, loose contact has been maintained. They met about every six months and exchanged information about the latest developments. And it was this that led to the actual collaboration, as NUM had significant advantages to offer in terms of automation and grinding technology. Especially for their wafer grinding machine.

  Why NUM?

  NUM’s NTC Manager in Taiwan, Johnny Wu, knows that GRINTIMATE had already tried other integration solutions:

  “NUM is not the first controller GRINTIMATE used for a wafer grinding machine.” Tricia Tsai VGM of GRINTIMATE adds: “We also use other Taiwan PC based brand controls. GRINTIMATE GTR-wafer grinder already meet the request of wafer thinning process (see box) for SiC, Si, GaN etc. However, another challenge in semiconductor fab acceptance is the integration of SECS/GEM and loader/unloader system for the GTR, which the NUM system will help to fulfill.“

  Automation of wafer grinding machine

  Ultimately, the challenge was to automate a GTR-1215 grinder. Johnny Wu explains what the real challenges were:

  “First, there might be two or more robots that transfer wafers in and out (it’s so called EFEM/Equipment Front End Module) to the GTR-1215. A special protocol for the communication of the selection of front-end robots, the logistics method between EFEM and the host machine, the communication between SECS/GEM and the host system, and the integration of BC (Block Control) was needed.

  Therefore, the controller should be able to receive the signal from the robot and start the rest of the process. After the GTR-1215 finishes grinding, our controller also needs to send a signal to the robot to ask it to transfer the wafer. Developed by the SEMI (Semiconductor Equipment and Materials International) organization, SECS/GEM is the standard defining a semiconductor’s equipment interface protocol for equipment-to-host data communications. Integrating the SECS/GEM protocol was easy because our controller is open and flexible.

  Second, the precision of the grind process requires extensive spindle current monitoring. The NUM controller can directly collect current information from MDLUX drives and then the HMI software collect all this information in one database. We also offer special functions for AC grinding, which include not only monitoring but also adaptive control of the feed to stabilize the current. This achieves better surface quality and shortens grinding time.”

  Experience from this cooperation

  The project highlights NUM’s ablility to support GRINTIMATE in the integration of a complete production line for wafer grinding. Current monitoring and pressure monitoring were integratedand NUM created a special HMI for GRINTIMATE to ensure optimum machine operation. NUM also provided PLC NC machining macros, motor tuning and commissioning for this project, so a total solution for GRINTIMATE. This means that GRINTIMATE could concentrate fully on its main competencies in machine and grinding technology.

• STM waterjet, one for all – with help from NUM (Aug 31, 2023)

  As a leading supplier and specialist for water jet cutting systems, STM offers a complete service, primarily for companies working in the processing of steel, aluminium, non-ferrous metals, stone, glass, plastic or sealing materials. STM is able to further extend its leading role, with NUM as its competent and solution-oriented partner for CNC control. Based in Bischofshofen, Austria, STM has been developing leading-edge product solutions for more than 20 years.

  STM water jet cutting systems bring many advantages as tools for cutting unique forms in almost all materials. Simple programming and control of the water jet, via a highly intuitive MS Windows interface, is standard for STM water jet cutters. The water jet can cut almost all materials with a thickness of 100 mm and greater.

  

  STM manufactures CNC controlled systems in all sizes and for almost any application possible. During design and construction, a great amount of attention is paid to the system’s transportability, ease of use and ease of maintenance, as well as its functionality and cost effectiveness: regardless of the model, all structural parts and screws are made from corrosion-resistant stainless steel or aluminium. The system is extremely manageable and compact, thanks to its flat underbody, smooth side walls using concealed linear guides without bellows, and a high-pressure pipe entrained in the axis. The systems offer a choice of four bridge widths, each available in a range of different lengths, and are divided into three product series: ’EcoCut‘, ’Standard‘ and ’Premium‘. The product series correspond to the most common user profiles in terms of the different technical features they offer. The modular construction of the system guarantees that customers can target their investments in the functions they need at the time, without having to plan far in advance. This makes STM’s systems attractive not just from a technical aspect, but from a cost aspect too.

  The fully digitalised drive also contributes to the systems’ cost-effectiveness, with brushless AC servomotors and multi-axis CNC control from NUM, which can process very large amounts of data, even in reload mode. The software for this runs under MS Windows and can be installed and run on standard PCs as often as desired without incurring extra costs. Drawings can be made directly in the cutting program, where the cutting pressure and quantity of abrasives can also be specified very easily. The NUM FS152i P2 operating unit is integrated into a separate control panel, ensuring maximum user comfort, control flexibility and safety. STM only uses top quality high-pressure pumps in its water jet cutting systems. If desired, the system can cut at pressures as high as 6000 bar, with a power requirement of 11 - 75 kW and a flow rate of 1 - 10 litres per minute.

  There are many different configuration options, depending on the individual requirements. These include automatic height scanning with collision protection, low-pressure monitoring in the abrasive metering system and the option to operate several cutting heads simultaneously. STM presents the whole spectrum of relevant options to a potential customer as part of an individual requirements analysis.

  Through continuous advice, training and an extensive replacement parts and maintenance service, STM makes sure that its customers› manufacturing processes remain as profitable as possible for as long as possible. The customer support from STM ranges from technical advice, business planning and sample calculations, to project planning for complete systems, test procedures, shipping and sales training.
  Alongside technology for the future and quality as standard, STM puts a particular focus on innovative, complete service. This way, the company can ensure that its customers’ individual production processes can continually be adapted to suit their current requirements.

• Mastering even the most complex workpieces – a revolutionary, 9-axis CNC controlled, weld overlay machine (Aug 31, 2023)

  TIG weld overlay technology is an advantageous way of meeting the increasing demand for metallurgical bond CRA manifolds and other workpieces. It is of a suitable quality for production systems and for crude oil exploration applications. 100% defect-free CRA deposition, reasonable cost, increased efficiency and high flexibility are the reasons why companies have chosen and are successfully using POLYSOUDE’s unique cladding technology, controlled by the Flexium+ CNC System from NUM, in their production processes.

  Just as NUM is known as being a reliable partner when it comes to specialized and customized CNC automation, POLYSOUDE is a reliable partner when it comes to automated welding and cladding. 

  POLYSOUDE is renowned for its expertise in orbital TIG welding, with an extensive product range which includes highly efficient equipment for mechanized, automated, robotic and automatic welding systems, as well as solutions for weld overlay applications. Through close cooperation, POLYSOUDE and NUM have developed the 9-axis CNC controlled weld overlay machine shown on these pages, which is one of the most precise systems available on the market today.

  

  Installations designed for cladding in a vertical position are usually dedicated to performing cladding operations on cylindrical parts. In most cases the workpieces are positioned on a turntable or positioner. However, there are other, much more complex scenarios, where it is impossible to set the workpieces in motion, either due to their size and weight, or quite simply because of their geometry (e.g. eccentric bore holes or nozzles). A group of endlessly rotating collector welding and cladding heads, with torches which can be rotated without twisting the cable/hose bundles, has been specifically designed for such situations. These machines handle cladding operations on fixed workpieces with a high level of automation.

  The automation of this machine is controlled by a Flexium+ 68 CNC from NUM. Eight of the nine axes are equipped with powerful single-cable motors and Safe PLC. Operation of the machine is achieved either via a NUM nPad with a personalized GUI (Graphical User Interface) for welding operations, or via a NUM FS152i machine panel with an additional 12" display, also utilizing a personalized GUI. Even more complex workpiece geometries - such as manifolds with intersections or cross sections - 'bore to bore' functions, supported by the NUM CNC system and the personalized POLYSOUDE GUI.

  But what exactly is weld overlay – and what is it good for? Cladding is a welding procedure that deposits a wire filler metal on the surface of the workpiece, as opposed to joining two pieces of material. Generally this is used for corrosion resistance or wear resistance and frequently a different material is used for the clad than for the base metal. Orbital cladding can be done by orbital pipe weld heads using cold wire. In some cases, hot wire technology can be used. In hot wire welding, a power supply controls the heat of the filler wire almost to its melting point prior to its introduction into the weld puddle. Arc energy that would usually go into melting the wire provides more penetration and increases deposition beyond what is possible with standard cold wire TIG. In cladding applications the hot wire solution can result in weld deposition that approaches MIG speed, but with TIG quality.

  The Hot Wire TIG welding process is a benchmark in the area of automation for high-quality coating or buttering operations. There is no question of replacing other processes where such a choice is appropriate, but this technique should be considered where the shape to be cladded is complex, where space constraints are severe or quite simply where a higher level of automation is desirable. At POLYSOUDE, a range of standard equipment and several specific solutions are available to cover the diversity of applications. 

  

  

  Like NUM, POLYSOUDE has been in business for over 50 years, during which time it has expanded its operations throughout the world. POLYSOUDE has about 250 employees, making it about the same size as NUM. With its own 13 subsidiaries, which provide a combination of sales and services, POLYSOUDE is close to its customers worldwide. And also just like NUM, POLYSOUDE has built up a relationship with its customers and partners based on trust. "Our strength lies in our collaborative approach, backed up by specialists like NUM, working in synergy and adopting a "Zero Risk / Zero Defects" approach in dealing with customers", says Mr. Hans-Peter Mariner, CEO of POLYSOUDE. The company is always at the cutting edge of R&D; its experts' combination of experience and innovation has led to it being acknowledged as a trailblazer in its field. "The 9-axis CNC controlled weld overlay machine is the result of close cooperation between POLYSOUDE and NUM", adds Mr. Elia Barsanti, Director of NUM France.
