Hi I'm Angela Busby I'm a trainer here at Stuller and on this segment of How it Works we're going to show you how to operate an ultrasonic polisher. This is the handpiece. The handpiece plugs in right here and your foot pedal plugs in the back and of course you to plug in your machine. We're going to turn the machine on and you have a series of of buttons on your display here. You have an unclamp and a clamp button which is to tell you what tool you're using. If you're using your ceramic stone you're going to press your unclamp button. If you're using the metal attachment that is provided with the machine you press the Clamp. Then you have a series of resets or the foot federal controller and then you have a display. The display is basically going to show you where your own settings are. And here's your power control button. Now you have watts and you have power. you want your machine to be set on power so if You press here it goes to watts. Make sure you're pressing it to the power button and make sure you're pressing your unclamp button and then you're while you're setting your setting you're going to hit the reset and it's going to show you what setting you're at. So I like to work with mine around 19 to 22 and that way it doesn't get too hot. If you're working with it the handpiece can get a little hot. So you're setting your control your power control that might be set a little too high it can cause your hand piece to overheat or make some terrible sounds. I mean it's not that dangerous but the sound will annoy you. So make sure you're setting is on 19 to 22 and then if you're using the tool that comes with it the one piece tool and you're hitting clamp you can go all the way to 39. This is the tool that is provided with it. It is a one-piece diamond wheel diamond tool so that would be inserted in your hand piece and then you change your setting up here and it's provided with your tools. You have an Allen wrench so we use three different ceramic stones with the machine. We use the 800-1000 and 1200. I suggest the 1200 because it is not as coarse and of course you would like to use something that you're only willing to remove that roofs this so if you have something that's really really rough and you're needing to work it and it needs a lot of work you may want to go with 800 grit. But like I said I try to stick with the 1200 grit. And it's a lot easier to use these tools when you're removing the scratches that the machine creates. So the way you're going to change your tool is we're going to turn it off turn it off here and if you use your allen wrench put your tool and select which one you want. These come in four inches and I usually break this in three. You get a lot more use out of it and if this is too long when it's in the machine it actually is going to work itself out. So once you start working with it it just starts shifting because it's so long and it's not as aggressive if you have it in there too long. So break your still sections into about three sections and place it in their center and tighten it. If you tighten it too tight it will overheat and will make noise and if it's not tight enough it kind of makes noise and let you know that it's just not tighten up. So now we're going to go ahead and turn it on and we're gonna start operating the machine. So again we don't want the flip that alone so we want that to be reset. Now we're using just the handpiece without the foot pedal and our display is on and its own power and we're set at 19 so we're going to start working this. There's no getting around that sound so you're just gonna have to deal with it but if the machine is set too high and it snakes and evenmore aggressive sound. So this thing about working with ultrasonic polisher is that if you're working with around you can keep the rounds around you're working on a flat you keep the flat flat. And everything is nice and crisp and we're going to remove whatever text just on there that we're not wanted. And if I need to sharpen the ceramic stone what I'm gonna do is I'm just going to use one of these blue, it's a sharpening stone we sell them here at Stuller, and you can just shape it to what you need. If you need is nice and sharp for you needed half round one in a flat on the other hand it's just very simple tip to shape. We have removed everything that we would like to remove we're going to put our hand piece down and then we're going to go ahead and start with our radial bristles. The radial bristles will remove anything that you have put on there with that ceramic stone. The ceramics don't leave a little scratchy surface so we want to go ahead and take that scratchy surface off. I'm going to start with the red radial bristle and we will put that in the flex shaft or your micromotor. We sell flex shafts and the micro motor here at Stuller and i'm going to go ahead and set this probably midway. And the good thing about the micromotors they do not have the torque that flex shaft may have so i really like working with micromotor. Ok so we're going to come in there and we're going to remove all of that ultrasonic polisher texture that we just put on there. The thing about the radial bristles is that they are rubber wheel the very flexible so you can get in all the little nooks and crannies without causing any kind of issues from the rubble wheel so they're perfect to use for this kind of thing. And then we're going to change it to the blue rubber wheel same thing with these radial bristles. You have different grits and there is a yellow one that I find a little too coarse so I didn't want to show you that one but I use the red one and then I go to the blue one and it it's a nice finish on there with the blue. Alright so by going over this with the radial bristle this is going to make this job a lot easier to polish when we're all said and done.
