STLC boring bar

STLC boring bars are essential tools for internal turning operations, particularly when dealing with small bores or reaching deep within a workpiece. These bars, characterized by their steel shanks and carbide heads, offer a balance of rigidity and affordability, making them a popular choice for various machining applications. Understanding their features, applications, and selection criteria is crucial for achieving optimal performance and precision.Understanding STLC Boring BarsWhat is an STLC Boring Bar?An STLC boring bar is a type of cutting tool used in lathes and boring machines for enlarging or finishing existing holes. The 'ST' signifies a steel shank, 'L' typically denotes the tool's overall length in relation to its diameter, and 'C' indicates a carbide cutting tip or head. The steel shank provides the necessary rigidity for stable cutting, while the carbide tip offers excellent wear resistance and cutting performance.Wayleading Tools offers a wide range of STLC boring bars, catering to diverse machining needs. Our selection includes bars with varying lengths, diameters, and carbide grades to ensure optimal performance in different materials and applications.

Carbide Head: Offers excellent wear resistance and cutting performance, allowing for higher cutting speeds and longer tool life. Internal Coolant Channels: Many STLC boring bars feature internal coolant channels to deliver coolant directly to the cutting edge, improving chip evacuation, reducing heat, and extending tool life. Interchangeable Heads: Some advanced designs allow for the replacement of worn or damaged carbide heads, extending the life of the bar and reducing tooling costs.Applications of STLC Boring BarsInternal Turning OperationsThe primary application of STLC boring bars is in internal turning operations, where they are used to enlarge or finish existing holes to precise dimensions and surface finishes. This is crucial for creating accurate and functional components.Deep Hole BoringSTLC boring bars are especially useful for deep hole boring, where the length-to-diameter ratio of the hole is significant. The rigidity of the steel shank helps to prevent deflection and maintain accuracy over long distances.Finishing BoresSTLC boring bars are also used for finishing bores to achieve tight tolerances and smooth surface finishes. The carbide tip provides a sharp cutting edge that can produce high-quality results.Selecting the Right STLC Boring BarMaterial of the WorkpieceThe material of the workpiece is a critical factor in selecting the right STLC boring bar. Different materials require different carbide grades and cutting geometries. For example, machining hardened steel requires a more wear-resistant carbide grade than machining aluminum.Bore Diameter and DepthThe bore diameter and depth will determine the required diameter and length of the boring bar. It is important to select a bar that is rigid enough to prevent deflection, but also small enough to fit inside the bore.Machine Tool CompatibilityEnsure that the STLC boring bar is compatible with your machine tool's spindle and tool holding system. Check the shank size and type to ensure a proper fit.Coolant DeliveryConsider whether you need a boring bar with internal coolant channels. Internal coolant delivery can significantly improve chip evacuation, reduce heat, and extend tool life, especially in deep hole boring applications.

This will help to minimize vibration and deflection.Appropriate Cutting ParametersSelect appropriate cutting parameters, such as cutting speed, feed rate, and depth of cut, based on the material of the workpiece and the recommendations of the tooling manufacturer. Refer to the carbide insert manufacturer's data for recommended speeds and feeds.Regular Inspection and MaintenanceRegularly inspect the STLC boring bar for wear and damage. Replace worn or damaged carbide inserts promptly to maintain cutting performance and prevent damage to the workpiece.Minimize VibrationVibration is a common problem in boring operations, especially with long boring bars. Take steps to minimize vibration, such as using a vibration-dampening tool holder, reducing cutting speed, or increasing feed rate. Wayleading Tools can provide recommendations on vibration-dampening solutions for your specific application.STLC Boring Bar Specifications and DataHere's an example table showing typical specifications.
