1 00:00:10,730 --> 00:00:16,010 Part one of our three part introduction to turning series, firstly, a list of 2 00:00:16,010 --> 00:00:20,130 the tools and materials which will be used throughout the series, starting with 3 00:00:20,130 --> 00:00:25,010 the aluminium bar, which will be used to create a small component. 4 00:00:25,010 --> 00:00:28,650 Using the center lathe, along with the basic knife tool. 5 00:00:28,650 --> 00:00:33,730 The knife tool will be used for facing off, turning into a diameter as well as a 6 00:00:33,730 --> 00:00:37,290 small chamfer on the front end. 7 00:00:37,290 --> 00:00:42,130 During the turning into a diameter phase we will also be using a 25 to 50 8 00:00:42,130 --> 00:00:47,250 millimeter micrometer for accurate measurements of the diameter and also to set 9 00:00:47,250 --> 00:00:48,970 the digital readouts on the machine. 10 00:00:49,490 --> 00:00:53,250 We will then move on to form a thread, a female thread on one end using the 11 00:00:53,250 --> 00:00:59,090 Jacobs chuck and key, a number four centre drill, an eight and a half 12 00:00:59,090 --> 00:01:01,370 millimeter tapping drill. 13 00:01:01,370 --> 00:01:06,170 Then we will later go on to use the tap wrench with a series of taps. 14 00:01:12,810 --> 00:01:16,650 This part of the process will also require the use of some lubricant. 15 00:01:20,010 --> 00:01:24,730 The square drive chuck key is used for tightening the material into the chuck 16 00:01:24,850 --> 00:01:27,770 and securing its in place for the work to be done. 17 00:01:27,770 --> 00:01:32,610 To begin with, we mount the knife tool into the tool post a simple case of 18 00:01:32,610 --> 00:01:37,050 slotting it into the preformed slot and then tightening it up to make sure that 19 00:01:37,050 --> 00:01:41,690 it's secure. It has already been pre centred ready for turning, mounting the 20 00:01:41,690 --> 00:01:46,810 material into the chuck, tightening up with the chuck key and giving a little 21 00:01:46,810 --> 00:01:49,250 nip at the end just to make sure that it's fully secured. 22 00:01:52,970 --> 00:01:55,090 Safety first, make sure the guard is lowered. 23 00:01:58,130 --> 00:02:02,210 Using the lever, we switch the machine on and then we begin to manoeuvre the 24 00:02:02,210 --> 00:02:06,730 knife tool into position to touch onto the material and begin the facing off 25 00:02:06,730 --> 00:02:13,410 process. When initially touching on, it is a good idea to go slowly at first 26 00:02:13,770 --> 00:02:17,330 removing only a small piece of material and to see how it's responding. 27 00:02:20,650 --> 00:02:25,130 Once satisfied with the initial touching onto the material, manoeuvre the knife 28 00:02:25,130 --> 00:02:30,690 tool into position to begin facing off properly and create a nice, smooth datum face. 29 00:02:42,210 --> 00:02:46,610 The knife tool is doing its work in removing that material from the front face 30 00:02:46,610 --> 00:02:48,490 and the new front face is being revealed. 31 00:02:51,010 --> 00:02:55,930 And this front face, once finished, will be a nice, smooth, even datum face. 32 00:03:00,130 --> 00:03:06,010 Speeding up the process to save time, a nice, even smooth datum faces is emerging. 33 00:03:13,730 --> 00:03:17,010 Coming up now to the last piece of material to be removed. 34 00:03:19,570 --> 00:03:26,290 Back into real time, touching off the material and switching off the machine. 35 00:03:26,290 --> 00:03:31,890 Winding the knife tool away to allow room to inspect the material, a good 36 00:03:31,890 --> 00:03:36,410 result, the new face of the material is smooth and balanced and ready for the 37 00:03:36,410 --> 00:03:39,970 digital readout to be calibrated on set at zero. 38 00:03:42,130 --> 00:03:46,810 To do that, the knife tool needs to be touched back onto the material. 39 00:03:46,810 --> 00:03:52,210 The Z axis on the digital readout will be set as a datum, recalibrating it to 40 00:03:52,210 --> 00:04:00,690 zero. This concludes facing off a piece of material, the knife tool was 41 00:04:00,690 --> 00:04:05,850 mounted, then touched onto the material, faced off the material and 42 00:04:05,850 --> 00:04:10,770 recalibrated the new faces of datum using the digital readout. 43 00:04:10,770 --> 00:04:15,210 In the next video, we will turn the material into a new diameter and also a 44 00:04:15,210 --> 00:04:16,530 small chamfer on the end.
