Spool to Spool System
Royal Master is proud to introduce the Spool to spool system. Its capabilities are designed to revolutionize many different industries.
- Grind Continuous Medical Guidewires for inventory reduction and Work in Process Reduction
- Thrufeed Grind NiTi to a consistent removing the oxide at a rate of 1" / Second ( 25mm/sec )
- Grind your Braded Catheter Tubing
- Add Polymer Coating processes after grinding in-line
- Thrufeed Grind your tungsten wire to a specific wire diameter for future processing.
The machine feeding system is capable of taking a spool of raw material up to 30 lbs in weight, down to .010" diameter and feeding it to another spool. All while rotating at 2000 rpm, and level winding for a uniform wrap. The centerless grinder pictured in the center of the unit is manufactured by Royal Master and coupled with this system can grind continuous profiles into a product or simply Thrufeed grind your material to a consistent diameter.
After exiting the centerless grinder, a laser gauge will read the diameter and if necessary feed back to the machine a size compensation to the diameter of the product. It will also calculate all the necessary SPC data
The system is available as a stand alone for your own propriety integration of a process or Royal Master can integrate the centerless grinder process for you.
The system is robust in its design and can accommodate spools in size up to 14" diameter and 4" wide. The quick change design of the spools makes for a seamless change from one product to another. The payout and take up spools use a heidenhein encoder to track the length output of the wire and displays the dispensed material on the screen. The system can be programmed to stop grinding after a pre-programmed amount of material has been ground. The exit spool can be changed out and grinding can resume at the same or different diameter.
The spool system comes enclosed in a protective interlocked cage for safety, and all programming is done through an intuitive touch-screen with easy to use inputs.
