Why choose DAN Technology for my robotic polishing needs?

---

DAN Technology develops and delivers complete turnkey machines that are tested and approved for the quality and consistency of finishing, the time cycle and the quality of construction prior to shipment and installation in our customers' facilities. The machines include the tooling and programs needed for operation and the machines may be placed into production immediately at the conclusion of the installation.   

DAN Technology created a very highly sensitive and proactive force control system nearly 40 years ago, which has been improved and enhanced many times over the last decades. This system allows the units to adjust their position in real-time forward or backward to achieve a consistent work on the piece. This tool allows for completely different working pressures on different areas of the piece and at all times there is a reaction speed linked to that pressure. Essentially the units mimic the best manual operators in terms of the movements and pressures that are used to make the best finishing on the pieces. As the units have the ability to adjust their positions as the robot moves along a surface, it's not necessary to create "perfect" robot paths and therefore a small fraction of recorded data points are needed in order to create a good working program when compared with other robotic systems.  

Other systems tend to require program touch-ups and sometimes even major adjustments every time a new batch of parts arrives to be ground or polished. The DAN machines almost never require these types of program touch-ups so long as the setup of the machine remains the same and the parts coming into the machine are within a reasonable range of variation. DAN has some customers who are operating with the same unmodified programs for ten years or more. 

Because the units are able to deal with the typical part variations and imperfections of the robot paths, the finishing will be very consistent from piece to piece and batch to batch. 

As the units maintain consistent working pressure this leads to much less frequent moments of damage to belts or wheels, which occur when the piece touches the abrasives in an uncontrolled manner. This happens even with systems having pressure control methods that are too slow to react to the unexpected condition. In addition, the DAN systems will save abrasives because the work is done without having to force the issue by pushing the piece into the belt or wheel in order to be sure that work is being done. In other machines in order to know that every area is actually touched it's required to err on the side of being aggressive as the alternative often means there are unworked areas that need to be done manually following the process. 

Due to the control of the process as explained above, DAN's machines typically require less powerful motors and consume much less energy to achieve the results. If a machine doesn't have the same level of control and the goal is to ensure that the piece is worked, then to avoid having the wheel or belt literally come to a stop during the process, a more powerful motor is required to push through the increased coupling friction that's being generated. 

All of the above explanations lead to an obvious conclusion regarding the expectation of maintenance costs. Any machine working under conditions where there is less stress and vibration will clearly be expected to work for much longer periods of time before mechanical wear occurs. This has been proven true from our experience.  

Because of the above facts, the DAN machines are extremely reliable and generally run for years without any major issues. In the event that a problem occurs, DAN is able to connect remotely to the HMI in order to assist in troubleshooting quickly. We also use a combination of direct access along with videos and file transfers in order to help our customers get back into production quickly. A great majority of the components used in the machines are standard off-the-shelf components that DAN keeps in stock for fast shipment. In the event that a special component is damaged, DAN has the ability to produce the part in-house quickly without the need to rely on 3rd parties, which could and often does cause significant delays with other suppliers. An extremely high percentage of issues are solved remotely and quickly with good cooperation from our customers. This type of remote service assistance is free for the life of the machines.

• DAN has developed the most efficient and reliable robotic cell technology in the world and has proven this fact with real world results. 
• DAN's machines don't need to be constantly checked, tweaked and reprogrammed. 
• DAN has the experience and production capacity that is needed to handle any size polishing project required. 
• DAN gives excellent support to customers including free basic remote support for the life of the machines. 

These are just a few of the main reasons why to choose DAN for your robotic polishing needs.
