Metal Lathe

  1. 1. Metal lathe Tools and processes
  2. 2. S.Watson
  3. 3. Cutting Tools S.Watson
  4. 4. Setting up The point of the lathe tool must be centred at the same height as the tailstock tip. If this is not done the finish will be poorer. S.Watson
  5. 5. Part 1 Facing Off S.Watson
  6. 6. Facing Off A very basic operation is called “Facing Off”. A piece of steel is placed in the chuck and lathe cutting tool is used to level the end. S.Watson
  7. 7. Facing Off The cross slide moves and the cutting tool cuts the surface of the steel. S.Watson
  8. 8. Facing Off Only a small amount of material should be removed on each pass. S.Watson
  9. 9. Turning a taper The top slide is set at the desired angle. Small amounts of material is removed until the desired taper is achieved. S.Watson
  10. 10. Part 2 Drilling S.Watson
  11. 11. Drilling The tailstock can be used to drill with the aid of a drill chuck attachment. S.Watson
  12. 12. Countersink bit Using the countersink bit drill into the material slightly to create a starting point. Drilling without a countersink will make the drill bit slip. S.Watson
  13. 13. Twist drill Using the tailstock drill the desired depth of hole needed. S.Watson
  14. 14. Part 3 Knurling S.Watson
  15. 15. Knurling Knurling is the process of turning a pattern onto a round section. S.Watson
  16. 16. Knurling The pattern is usually used as a grip for a handle. S.Watson
  17. 17. Knurling The pattern produced is called the ‘knurled pattern’ S.Watson
  18. 18. Part 4 Turning a Long Taper S.Watson
  19. 19. Turning a long piece of material If a long piece of material is to be turned on the lathe, it may be supported by the tailstock centre. S.Watson
  20. 20. Turning a long Taper The material is held between two centres. The three jaw chuck will not be used as it doesn’t hold the material safely or accurately for this. S.Watson
  21. 21. Turning a long Taper The tailstock is adjusted so it’s off centre. S.Watson
  22. 22. Turning a long Taper This is the scale at the back of the tailstock. It’s adjusted so the tailstock is set off centre. S.Watson
