When performing lateral cutting with side cutting drill bits in metal machining, burrs frequently appear along edges, affecting dimensional accuracy, surface finish, and subsequent assembly. This is especially true during combined drilling and milling of materials such as steel, stainless steel, and aluminum alloys. The cutting force distribution and chip evacuation path of side cutting drill bits are often complex. Without proper control, significant edge tearing and micro-deformations can occur, making burr reduction a critical goal for many manufacturers.
With the increasing use of precise metal side cutting tools, manufacturers are demanding more from the geometric structure, coating type, and flute design of side cutting drill bits for metal. Side milling drill bits offer excellent stability and provide superior edge control in operations such as side milling, hole enlargement, and groove machining. Achieving optimal results requires proper parameter settings, tool selection, and process planning. Different metal materials exhibit varying heat generation, plastic deformation, and chip flow characteristics. If rotational speed, feed rate, and cutting depth are not adjusted accordingly, burr formation is almost inevitable.
Customized tools from OEM side cutting drill bit manufacturers are also becoming a crucial option for burr reduction. By optimizing cutting edge angles, improving tool rigidity, and tailoring tool designs for specific materials, manufacturers can significantly enhance stability and consistency in mass production. Choosing cutting drill bits with high-quality coatings further reduces cutting resistance and edge tearing, suppressing burr formation at its source.
Analysis of the Main Causes of Burr Formation in Metal Processing
Burrs have long been a critical factor affecting machining quality and subsequent processing efficiency. Especially when using high-precision cutting tools for lateral operations, improper handling or ignoring material characteristics can easily result in irregular burrs. These burrs compromise assembly accuracy and surface finish. Analyzing stress concentration, heat distribution, and chip evacuation during metal cutting helps identify the core causes of burr formation, enabling targeted process strategies to improve machining quality and extend tool life.
Stress and Deformation Issues During Side Cutting
During side cutting, metal experiences combined lateral and vertical stresses. Uneven cutting force distribution or insufficient tool rigidity can cause localized micro-deformation, leading to edge tearing. This is particularly common in high-speed cutting or machining hard alloys. By optimizing cutting parameters, selecting suitable metal side cutting tools, and employing proper feed strategies, stress concentration can be reduced, minimizing burr formation.
Edge Tearing Caused by Cutting Heat Accumulation
Machining generates significant heat at the tool-workpiece interface. If this heat is not dissipated efficiently, the metal surface softens and undergoes plastic flow, causing edge tearing and burr formation. This effect is most pronounced when working with high-strength steel or thick-walled components. Controlling cutting speed, applying effective coolant, and choosing an appropriate cooling strategy for metal side cutting drill bits help alleviate heat buildup, ensuring a clean and smooth cutting edge.
Material Accumulation Due to Insufficient Chip Evacuation
Inefficient chip evacuation is another major source of burrs. In side milling or lateral cutting, chips that are not removed promptly can accumulate between the tool and the workpiece, interfering with the cutting process and generating burrs. Adjusting cutting angles, optimizing flute design, and using OEM side cutting drill bits for metal help ensure smooth chip flow and improve surface finish.
Optimizing Side Cutting Drill Bit Machining Parameters to Reduce Burrs
To achieve high-quality surfaces and minimize burr formation, machining parameters must be carefully optimized. Spindle speed, feed rate, and cutting depth directly affect cutting forces, heat generation, and chip evacuation. By balancing these factors, material deformation and plastic flow can be controlled, significantly reducing edge burrs. Tailoring parameters for different metal types and thicknesses improves machining efficiency and extends the life of metal side cutting tools. Integrating process design with parameter optimization is especially important when using OEM side cutting drill bits for stable and consistent results.
Rational Combination of Spindle Speed, Feed Rate, and Cutting Depth
Excessively high spindle speeds can rapidly increase cutting zone temperature, softening the metal and causing burrs. Too low speeds increase cutting forces and promote tearing. Feed rate and cutting depth are equally critical; values that are too high increase tool load and surface roughness, while too low reduce efficiency. Adjusting the speed and feed of the side milling drill bit to balance cutting force and heat ensures clean, smooth edges.
Parameter Adjustment Strategies for Different Metal Materials
Metal hardness, toughness, and thermal conductivity vary widely. Aluminum, with low heat resistance, performs best with higher spindle speeds and lower feed rates. Stainless steel and titanium alloys require slower cutting, increased tool rigidity, and adequate cooling and lubrication. Optimizing parameters based on material characteristics reduces burrs and extends the life of metal side cutting tools.
The Importance of Maintaining a Stable Tool Path During Side Cutting
Tool path stability directly affects surface quality. Tool vibration or path deviation causes uneven cutting depth and edge burrs. Planning cutting sequences, securing the workpiece, and using high-precision side cutting drill bits maintain consistent paths. Combining parameter optimization with superior tool performance effectively reduces burr formation while maintaining efficient machining.
Choosing the Right Side Cutting Drill Bit for Metal
Selecting the appropriate side cutting drill bit is critical for smooth surfaces and burr reduction. Tool material, structure, and coating affect cutting forces, chip evacuation, and wear resistance, determining both surface quality and tool life. High-performance metal side cutting tools withstand heavy cutting loads while maintaining stability during high-speed and complex side milling operations. Using OEM side cutting drill bit manufacturers’ tools, along with optimized parameters, achieves high-precision edge finishing on various metal materials.
Influence of Tool Substrate and Structure on Burr Control
Tool substrate hardness and toughness determine wear resistance and deformation control. Carbide tools maintain sharp edges and reduce material plastic flow, lowering burr probability. High-speed steel tools suit ductile metals like aluminum or copper. Geometric features like rake angles, helix grooves, and tip shapes affect cutting force and chip evacuation, crucial for smooth edges.
Differences in Performance of Coating Types in Metal Machining
Coating types vary in wear resistance, anti-adhesion, and thermal stability. TiAlN reduces temperature during high-speed cutting of hard metals, minimizing edge tearing. TiN and TiCN perform well on aluminum and softer steels, reducing adhesion and burrs. Selecting coatings based on workpiece material enhances surface finish and extends tool life.
