Tube polishing machines are one of the two main techniques in the production of flat polish, or flat sanding. This technique is used more often for the production of metal objects than any other technique. It is also called curved sanding or needle polishing. The process uses two cylindrical polishing rollers and a rotary cutter that are connected to one another by a connecting rod.
The first step is to cut a slit in the flat metal. The slits are located along the length of the tube. You should make these slits equal in length so that the strips of metal will be perfectly straight when the polishing is done. Once the slit has been made, you will need a feeding system that has a small opening on one end that will accept a cleaning rod that is inserted into the slit. You will make use of a similar type of system as used for the polishing of curved tubes.
Next, the tube must be heated until it gets hot enough to melt the wax that is to be used for the mirror polishing. The wax is then moved from the flat side of the tube over the feed system using a syringe or a cotton swab. This syringe and cotton swab are operated by a motor that is controlled by the operator. The cleaning rod can be kept inside the tube while the polishing is going on to prevent any damage to it.
The next step is to heat the feed system and move it towards the side of the tube finishing the feed system by heating the plastic tubing and the metal tubes. After this has been done, the tubes are removed and the polishing machine is started. The next step is to push the needle back into the slot in the opposite direction of the polishing so that the polishing operation will run the length of the tube. The needle must not touch the ground as it will cause damage to the machines tools.
The final and most important step is to fire the round tube polishing machine on. It is advisable to test this out first by pushing a little in the slot to see if the tool moves in the direction that you want. The feed system will engage and push the brush up into the tube. As the feed moves down the tube, the ribbon will engage and pull the brush into the tube slot which makes the tool work up and down the length of the tube. A clear indication of when the tooth is engaged and closed will be displayed in the indicator on the screen.
This process is repeated to make sure that the polishing head does not slip off the end of the stainless steel tube. When this has been done, the polishing operation can be started on the other side of the tube and continue till the entire length is polished. The same type of technique is used to ensure that the alignment of the slot is perfect to prevent premature wear on the machine tool and blanks. With a little care, this kind of equipment can last for many years.
