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?
