Training Instructions for Reino

Start with no tool installed Get the demonstration block

Endgoal

  • Remove tool, install tool, move to place and drill a hole
  • End goal should be a hole pattern with some spacing (e.g. square 4-hole pattern with 15mm between centers)

Describe what the machine is

  • Bridgeport knee-stype
  • X Y Z axis
  • Spindle
  • Quill/drilling
  • Best for drilling holes, then milling
    • If just planning to drill, skip the milling part
  • Check that it's in correct configuration, what needs to be locked, what needs to be unlocked.
  • PPE: Eyepro always, hearpro sometimes, music never
    • Never touch quill when the mill is running
  • Be aware of chips
    • Plastic chip protector

How to turn the mill on

  • Switch power
  • Check the E-stop
    • E-stop is for emergencies, not for stopping
  • Turn the spindle on
  • Check the spindle direction
  • Switch for the power feed power
    • Each power feed has a led to show it's on
  • Quill locked for milling, unlocked for drilling
    • (Touch off for rough leveling, not recommended: inaccurate and rough)
  • Feed worm for auto-feed quill (advanced feature, later lesson)
    • Make sure that quill autofeed does not turn (the thing on the left side must not be spinning)
  • Low gear vs high gear setting
    • Keep the high gear unless you know what you are doing
    • Press and turn, rotate the spindle, make sure it locks
  • Spindle direction
    • Low gear changes the spindle direction
    • piece of tape hanging off
  • change the speeds with wheel
    • Mention the DRO, explain later when the tool is on

Practical part

  • Start with installing the tool
    • Mention that the taper centers the tool and has to be clean
    • Drill chuck
      • !Only for drills, never for mills
      • Install the drill bit
      • Less accurate than collet
      • Use the tool (pin spanner) to tighten
      • ? Mention ISO tapers and how to take the spacer out (will be semi-obsolete in the near future)
    • Hold the tool and screw the drawbar
    • Stepladder
    • Brake the spindle and two-finger tighten
    • Remove the tool
      • ? Demonstrate with M12 thread
      • Hold the brake
      • Unlock the drawbar, handtighten back and unscrew half a turn
      • Hold the tool and gentle tap on the bar
      • Firm grip on the tool when unscrewing the draw bar.
    • ! Make everyone install move the table and remove the tool.
  • Controls
    • Backlash
    • ? What is Z axis backlash direction
  • Clean the table, vice and parallels
  • How the vice works
    • Removing the pins for more area and cleaning
  • Install the demonstation block
    • Put in the parallels
    • Put the block on the parallels
    • initial tightening of the vice
    • Show how the tapping work with deadblow hammer
    • For steel use brass hammer
    • Parallels snug
    • Tighten
    • Hydraulic vise always has jaw lift
  • ? Let the trainees install the part?
  • DRO
    • ! DO NO BREAK THE GLASS SCALES
    • Everything has flex, measure the part
    • Zero it out
    • How to read it
    • half digit accuracy
    • can't get back to 0.0 due to structural reason
  • X Y Z locks
  • ! Do not drill into the table
  • Drill some kind of pattern
    • Use the guidelines on the wall
      • Carbide goes fast
    • Quill end stop
    • Lubricant
      • ! Alcohol strips lubrication and has water, do not use with Reino
    • Chip breaking
    • Brushing/cleaning/vaccuuming during operations
      • Avoid pressurized air
  • ! Make trainees repeat the drilling

Cleaning up and powering the machine off

  • Vacuuming
  • Remove long chips by hand, pliers or chip hook
    • If low suction check the hose for blockage
  • Wipe the floor with a lasta, there will always be chips on the floor
  • Power off the mill from the on/off switch on the front panel

Reino maintenance

  • Where to oil
  • Once the day pull the lever to oil the ways
  • If the head makes a squaking noise lube the belts
  • ? Oiling the spigot?
