As we begin 2021, we have found ourselves in a situation where our lead-times have substantially increased due to COVID-19 pandemic-related issues.
Those issues combined with high demand and heavy shipping volume is resulting in a longer than normal delivery timeframes for many Tormach machines and accessories.
We are working diligently to resolve these issues and look forward to bringing our lead-times back to normal. Unfortunately, this is going to take some time.
As of now, we anticipate that these lead times will continue into the second quarter. We appreciate your patience during this time.

PECK DRILLING CYCLE (G83)

The G83 cycle (often called peck drilling) is intended for deep drilling or milling with chip breaking. The retracts in this cycle clear the hole of chips and cut off any long stringers (which are common when drilling in aluminum).

Program: G83 X~ Y~ Z~ A~ R~ L~ Q~

  • Q~ is a delta increment along the Z-axis

The G83 cycle is as follows:

  • Step 1: Preliminary canned cycle motion.
  • Step 2: Move the Z-axis only at the current feed rate downward by delta or to the Z position, whichever is less deep.
  • Step 3: Rapid back out to the clear Z.
  • Step 4: Repeat Steps 1 through 3 until the Z position is reached at Step 1.
  • Step 5: Rapid back down to the current hole bottom, backed off a bit.
  • Step 6: Retract the Z-axis at traverse rate to clear Z.

TROUBLESHOOTING

It’s an error if:

  • The Q number is negative or zero
