You’re ready to dive into your next machining project. You have the space, the tools and the materials. But, do you have a plan? More importantly, do you have the right plan in place?
Many drilling jobs require pecking cycles. To get the best results, you must choose the right pecking cycle for the job at hand. Your CNC machine shop in Louviers, CO offers the following guide to help you with your project.
What is a Pecking Cycle?
Pecking cycles are a method of drilling that involve drilling a little at a time. Rather than one long, deep plunge into the material, the drill goes through a cycle of passes, “pecking” away at the material. You can think of it as a woodpecker chipping away at a tree.
Why are Pecking Cycles Used?
Pecking cycles help prevent chip packing and breakage, aids the evacuation process, improves tool accuracy and minimizes walking. The final result is a better completed component.
When Should Peck Drilling be Used?
Peck drilling is typically used at CNC machines shops in Louviers, CO when the project requires drilling holes that are deeper than three and one-half drill diameters.
Why is the right pecking cycle important?
Not all pecking cycles are the same. Various cycles are used based on the materials being drilled, the type of drill being used and the product that is being created. By using the best pecking cycle, you will extend the life of your tools and improve their performance. Your machining will also result in a higher-quality final product.
Which Pecking Cycle is Best?
There are at least five different common pecking cycles to choose from. Different cycles should be used for miniature drills and high-performance drills. For high performance drills use, there are different pecking cycles for use on aluminum and aluminum alloys, hardened steels and pre-hardened steels. A good rule of thumb when choosing a pecking cycle is to base your choice on the hardness of the material. The harder the material, the shorter the pecking depths should be.
What Should be Avoided When Peck Drilling?
It’s important that chips not fall back into the drill hole as the drilling is completed. You should avoid letting the coolant or mist wash the chips back inside the hole. A good method to avoid this is to not pull the drill completely free of the hole as it undergoes the peck cycle.
Another thing to keep in mind is that peck drilling is not recommended when using carbide drills. The brittle carbide can be easily chipped during this process.
