Custom Iscar Insert Gun Drilling Index Drill System

Product Introduction

Key Features

Iscar Inserts

• The Iscar inserts incorporated into this drill system are of the highest quality. Crafted from premium carbide materials, they possess exceptional hardness and wear resistance. This enables them to effortlessly cut through a diverse array of materials, including hardened steels, stainless steels, and various alloys. The inserts are engineered with precise geometries that optimize chip formation and evacuation. Their sharp cutting edges ensure efficient material removal, promoting a smooth and continuous drilling process. Iscar offers a wide range of insert grades and coatings, allowing for meticulous customization based on the specific material and drilling conditions. For instance, a particular coating might be selected to enhance heat resistance and lubricity when drilling high-temperature alloys, thereby prolonging the insert's service life and maintaining peak cutting performance.
• The use of Iscar inserts not only guarantees outstanding cutting performance but also contributes to the overall reliability and repeatability of the drill system, ensuring consistent hole quality across multiple drilling operations.

Gun Drilling Technology

• The gun drilling technology at the core of this system is specifically designed for deep hole drilling. It features a long and slender drill 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. This coolant serves multiple essential functions. It effectively cools the drill and the workpiece, preventing overheating and safeguarding the integrity of the Iscar inserts. It also provides lubrication, reducing friction and facilitating chip evacuation. The unique design of the gun drill's flute and the high-pressure coolant work in harmony to flush chips out of the hole, minimizing the risk of chip clogging, a common obstacle in deep hole drilling. The long length and rigidity of the gun drill enable it to produce 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 gun drilling technology 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 system.

Index Drill Mechanism

• The index drill mechanism is a key innovation of this system. It allows for quick and convenient replacement or indexing of the Iscar inserts. When an insert becomes worn or damaged, the mechanism enables seamless indexing to a new, sharp insert without the need to remove the entire drill from the machine. This significantly reduces downtime and tool changeover time, maximizing productivity. The index drill mechanism also offers flexibility in terms of cutting strategies. Different insert geometries can be easily selected and utilized, depending on the specific requirements of the drilling operation. For example, one insert geometry might be optimized for rough drilling to rapidly remove material, while another can be employed for finishing operations to achieve a superior surface finish and precise hole dimensions. This adaptability makes the drill system suitable for a wide spectrum of drilling tasks, from initial hole creation to final precision machining.
• The indexing mechanism is designed with high precision and reliability, ensuring accurate positioning and secure locking of the inserts during drilling, thereby maintaining consistent hole quality and performance.

Customizability

• Our Iscar insert gun drilling index drill system offers extensive customizability. The diameter of the drill can be precisely adjusted to meet specific hole size requirements, typically ranging from a few millimeters to several centimeters. The length of the drill can also be tailored to accommodate different depth needs, with options available from relatively short to extremely long lengths. The system allows for the selection of various flute geometries, Iscar insert grades and coatings, and index drill mechanism configurations, all of which can be optimized for different materials and cutting conditions. Additionally, the shank design can be customized to fit different machine tool spindles, ensuring seamless integration and optimal performance. This level of customization empowers users to configure the drill system to suit a vast range of applications, from small-scale, high-precision machining in the electronics industry to large-scale manufacturing in heavy machinery and aerospace.
• The ability to customize the system based on specific needs makes it a highly versatile tool for diverse industries, enhancing production efficiency and quality across the board.

Precision Engineering

• The entire Iscar insert gun drilling index drill system is manufactured with meticulous precision. The drill body, shank, and the integration of the index drill mechanism and Iscar inserts are all engineered to the highest standards. The shank is designed to fit snugly into the machine spindle, minimizing runout and maximizing concentricity. The drill body is constructed from high-strength alloy steel, providing the necessary rigidity to support the inserts and withstand the rigors of drilling. The surface finish of the drill is carefully controlled to reduce friction and heat generation, enabling the drill 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 system meet the most exacting requirements for precision and performance.
• The precision engineering of this drill system 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.

Installation and Maintenance

• Installation: The drill system is installed in a CNC machine or a dedicated deep hole drilling 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's coolant hole, ensuring a proper flow of cutting fluid at the required pressure.
• Maintenance: Regular inspection of the drill system is crucial. Check for signs of wear on the Iscar inserts, such as chipping, dulling, or coating degradation. Inspect the coolant hole for any blockages and clean it if necessary. The drill 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 system shows significant wear or damage, it should be repaired or replaced to maintain optimal performance. Periodic calibration of the machine and the drill system may also be required to ensure continued precision and accuracy.
