How to Solve Chip Wrapping in CNC Drilling: A High Cost-Performance Solution for Precision and Efficiency

Traditionally, manufacturers often face a trade-off between machining precision and productivity. However, Hartford’s chips breaking for drilling technology enables both to be improved simultaneously. By stabilizing cutting forces and eliminating chip interference, the tool operates under more consistent conditions, leading to better hole accuracy and roundness.

At the same time, improved chip evacuation reduces the need for manual intervention and minimizes unexpected downtime. This allows continuous machining over longer periods, significantly increasing throughput. In many cases, overall production efficiency can be improved by 20% to 50%.

In mold & die machining, where cooling channels require high dimensional accuracy, chips breaking ensures clean internal surfaces. In semiconductor machining, where contamination control is critical, the reduction of residual chips and surface scratches is particularly valuable.

Additionally, tool life is extended due to reduced heat concentration and stable cutting loads. This further contributes to cost savings and process consistency.

Q1: Does chip breaking during drilling increase machining time?

A: The cycle time for a single operation may increase slightly, but overall efficiency is typically improved.

This is because chip breaking reduces machine downtime and minimizes the need for tool changes.

Q2: Are special tools required?

A: Standard cutting tools can be used with chip breaking strategies.

However, optimized tool designs can further enhance performance.

Q3: What materials is it suitable for?

A: It is suitable for most metals and engineering materials, such as steel, stainless steel, and aluminum alloys.

Q4: Does it affect machining accuracy?

A: It helps improve accuracy stability.
This is due to more consistent and controlled cutting loads.

Chip wrapping around the tool may seem like a minor issue, but it has a significant impact on machining quality, efficiency, and cost. By addressing this problem at its core, Hartford’s chips breaking for drilling function provides manufacturers with a practical and high-value solution.

With its combination of high cost-performance, improved precision, enhanced productivity, and extended tool life, this technology represents a meaningful upgrade for any CNC machining operation. For companies using precision machining centers and vertical machining centers, adopting chips breaking strategies is no longer optional—it is becoming a key factor in maintaining competitiveness in today’s manufacturing landscape.
