Sash Punching

Sash Punching
Overview:
            The process for punching window sash rails.
Definitions:
Procedure:

1. Locate sash labels and paperwork at the sticker desk to match the next cart to be processed.
   1. For sound latch and 2-point sash, we must punch all necessary punches.
   2. Check material for chips, breaks, damage. Verify parts are the correct size, color and profile as each sash is pulled and completed.
   3. If the cart is fabricated and is going to the fabrication welder, the parts will not need to be punched. Use the cutout to verify the parts while labeling skip to step 4.
   4. If fabricated but still needs the SH end punches, skip to step 3.
2. If not fabricated, pull to punch A5 or P27 for Studio.
   1. Remove the “interlock rail” and “pull rail” pieces of the sash, put end in the slot to the hard stop, then rotate and repeat.
   2. Use the cutout to identify where the lock will be placed on the lock rail for the part being punched. For regular locks, use the centering device on the machine to punch the center.
   3. For bottom-up latch (BUL) use the first stop pin on the punch.
      1. Vent left; bottom-up Latch’s (BUL) will be punched locating the end of the part to the right-side stop. For Vent Right, BUL will be punched locating the end of the part to the left side stop.
      2. BUL will be punched 10 3/16” ±1/8” from the end to the first edge of the punch out.
   4. For a two latch (2L) use the second stop pin on the punch.
      1. Punch latch holes in both ends for a 2L windows.
      2. 2L will be punched 6 3/16” ±1/8” from the end to the first edge of the punch out.
   5. Verify the quality of all the punches.
3. For SH punch a notch and weep holes in both ends of the pull rail in the SH bays of punch A3 or A9.
   1. For SV, use SV bay in the same punches to punch roller holes and weep holes in both ends of the bottom rail (single roller).
   2. For SV double roller and weep holes, punch in P6. Punch on both ends.
   3. Verify all punched holes are complete with no material or dangling pieces left in any of the punched holes.
   4. If there are anymore questions about the punching, see the samples on the board.
4. Place the sash label for that slot on the bottom rail of the sash (rail with weep holes) and return to original slot.
   1. Review cutout for any Vent Insert options. These will require a barcode label on the “Interlock Rail”.
   2. Carts going to the fabrication welder, place a green “Fab” Tag on the cart.
   3. If the sash is too narrow, the sash label will cover the weep holes. If this happens, relocate the sash label to the top rail.
5. Take the cart to the rebar staging area. If rebar is required, find batch number (located on labeled sash), find the corresponding batches cutout and then the row labeled with that batch in the cart. Measure the first piece of every new size to match with paperwork.
   1. Place the rebar in the correct interlock rail and continue until the batch is complete.
   2. When rebar has been slotted, sign off the sash punch log and stage cart for welding.
   3. If rebar is missing, DO NOT FOR ANY REASON, use any rebar that is not designated to that batch.
      1. There should not be any extra or less rebar than is specified on the cutout. If any issues with the rebar quantities are identified, inform the team lead to ensure the issue is correctly resolved.
