G73 Peck Drilling Guidelines (What to Know)
G73 peck drilling is a process used in CNC machining to efficiently drill holes in metal parts. This technique involves drilling the hole in multiple pecks, or short increments, instead of in one continuous motion.
G73 peck drilling can be a great way to reduce cycle time, extend tool life, and improve accuracy. In this guide, we’ll explore the benefits of G73 peck drilling, as well as some guidelines for achieving great results.
Benefits of G73 Peck Drilling
- Faster cycle time
- Extended tool life
- Improved accuracy
- Reduced noise and vibration
Guidelines for G73 Peck Drilling
Determine the optimal peck depth
The optimal peck depth will depend on the material being drilled, as well as the size of the hole and the diameter of the drill bit. In general, the peck depth should be less than the diameter of the drill bit.
Use a retract cycle
After each peck, the drill should be retracted from the hole to clear the chips and allow for coolant to be applied. The retract distance should be at least the same as the peck depth.
Use a coolant
A coolant should be used during peck drilling to help reduce heat and clear chips. The coolant can be applied through the spindle or through the tool itself.
Choose the right drill bit
The drill bit should be selected based on the material being drilled and the size of the hole. Carbide drill bits are often the best choice for peck drilling.
Monitor the process
During the peck drilling process, it’s important to monitor the drill bit and the hole to ensure that the process is going smoothly. If any issues arise, adjustments should be made to the peck depth or coolant flow.
G73 peck drilling can be a great way to efficiently drill holes in metal parts, while also improving accuracy and extending tool life. By following some basic guidelines and selecting the right drill bit and coolant, you can achieve great results with this technique.
Peck drilling can be particularly beneficial when working with tougher materials or when drilling deeper holes. So, try these guidelines and see the difference in your CNC machining process.
