Custom CNC Machining CNC Part Gundrill Tungsten Carbide Tipped Drill Bits

Product Introduction

Key Features

Tungsten Carbide Tips

• The tungsten carbide tips are the heart of these drill bits' cutting prowess. Tungsten carbide is renowned for its extraordinary hardness, second only to diamond in many respects. This hardness enables the tips to penetrate and cut through tough materials such as hardened steels, stainless steels, and various alloys with remarkable ease. The wear resistance of tungsten carbide is also outstanding, ensuring a long service life. Even after extended use, the tips maintain their sharpness, significantly reducing the frequency of tool replacements. This not only boosts productivity by minimizing downtime but also cuts down on tooling costs. Moreover, tungsten carbide has excellent heat resistance. During the drilling process, a substantial amount of heat is generated. The high heat conductivity and resistance of the carbide tips help dissipate the heat quickly, preventing overheating of the drill bit and maintaining the integrity of the cutting edge. This is crucial for achieving precise hole dimensions and smooth surface finishes. The specific grade of tungsten carbide used is carefully selected based on the target material and drilling conditions to optimize performance.
• The geometry of the tungsten carbide tips is meticulously designed. The cutting edge angles and shapes are optimized to promote efficient chip formation and evacuation. They are engineered to produce small, well-defined chips that can be easily removed from the hole, preventing chip clogging and ensuring a seamless drilling process.

Gundrill Design

• The gundrill design is specifically tailored for deep hole drilling. It features a long and slender body with a central coolant hole. High-pressure coolant, typically a specialized cutting fluid, is pumped through this hole and directed precisely to the cutting edges. The coolant serves multiple essential functions. It cools the drill bit and the workpiece, preventing overheating and safeguarding the integrity of the tungsten carbide tips. It also lubricates the cutting process, reducing friction and facilitating chip evacuation. The unique flute design of the gundrill is optimized to work in conjunction with the coolant system. The flutes are shaped to guide the chips along with the coolant stream, ensuring efficient removal of chips from the hole. This helps prevent chip clogging, which is a common obstacle in deep hole drilling and can lead to tool breakage and poor hole quality. The long length and rigidity of the gundrill enable it to create deep holes with remarkable straightness and dimensional accuracy, making it ideal for applications in industries such as aerospace, automotive, and machinery manufacturing, where precision deep holes are critical.
• The gundrill design is engineered to maintain stability and minimize vibration during the drilling process, further enhancing the quality of the drilled holes and prolonging the life of the drill bit.

Customizability

• We offer a high degree of customizability for our gundrill tungsten carbide tipped drill bits. The diameter of the drill bit can be precisely adjusted to meet specific hole size requirements, typically ranging from a few millimeters to several centimeters. The length of the drill bit can also be customized to accommodate different depth needs, with options available from relatively short to extremely long lengths. Different flute geometries and coolant hole configurations can be selected based on the target material and drilling conditions. For example, a more aggressive flute geometry may be suitable for softer materials, while a more refined geometry is preferred for harder and more brittle materials. The shank design of the drill bit can be tailored to fit different CNC machine spindles, ensuring proper and secure attachment. This customization allows our drill bits to be optimized for a wide range of applications, from small-scale precision machining to large-scale industrial manufacturing.
• The ability to customize the drill bits based on specific requirements makes them a versatile tool for various industries, including aerospace, automotive, machinery manufacturing, and more.

Precision Engineering

• The entire drill bit is manufactured with meticulous precision. The shank, body, and the integration of the tungsten carbide tips are all engineered to the highest standards. The shank is designed to fit snugly into the machine spindle, minimizing runout and maximizing concentricity. The body of the drill bit is constructed from high-strength alloy steel, providing the necessary rigidity to support the tips and withstand the rigors of drilling. The surface finish of the drill bit is carefully controlled to reduce friction and heat generation, enabling the drill bit to glide smoothly through the material and improving overall drilling efficiency and hole surface quality. Advanced manufacturing techniques and stringent quality control processes are employed to ensure that each component and the assembled drill bit meet the most exacting requirements for precision and performance.
• The precision engineering of these drill bits results in drilled holes with exceptional quality, minimal tolerance variation, and excellent surface finishes, reducing the need for secondary finishing operations and streamlining the manufacturing process.

Application Scenarios

• In the aerospace industry, used for drilling deep holes in turbine engine components such as discs, shafts, and casings, for cooling channels, fuel supply systems, and structural integrity.
• The automotive industry benefits from these drill bits in manufacturing engine blocks, cylinder heads, and transmission parts, creating deep holes for coolant passages, piston sleeves, and other critical components.
• In the machinery manufacturing sector, ideal for drilling deep holes in spindles, gears, housings, and other precision components, where accurate hole geometries and depths are essential for proper assembly and function.
• Can also be applied in the oil and gas industry for drilling holes in drill bits, downhole tools, and pipes, as well as in the manufacturing of firearms and other defense-related equipment.

Installation and Maintenance

• Installation: The drill bits are installed in a CNC machine following the manufacturer's detailed instructions. The shank is carefully inserted into the spindle and securely fastened using the appropriate clamping mechanism. The coolant supply system is connected to the drill bit's coolant hole, ensuring a proper flow of cutting fluid at the required pressure.
• Maintenance: Regular inspection of the drill bits is crucial. Check for signs of wear on the tungsten carbide tips, such as chipping, dulling, or coating degradation. Inspect the coolant hole for any blockages and clean it if necessary. The drill bits should be stored in a clean and dry environment to prevent corrosion. Lubricate the shank and other moving parts as recommended by the manufacturer. If the drill bits show significant wear or damage, they should be replaced or reconditioned to maintain optimal performance. Periodic calibration of the machine and the drill bits may also be required to ensure continued precision and accuracy.
