Wholesale PSBN turning tool holder

A wholesale PSBN turning tool holder is a crucial component in machining, providing stability and precision for cutting tools when working with hard materials like hardened steel, cast iron, and superalloys. Selecting the right holder is essential for achieving optimal performance, extending tool life, and ensuring high-quality surface finishes. This comprehensive guide explores the different types, key features, and selection considerations for PSBN turning tool holders available in the wholesale market.

Understanding PSBN Turning Tool Holders

Polycrystalline cubic boron nitride (PCBN or PSBN) is an extremely hard synthetic material used for cutting tools designed to machine hardened ferrous materials. A PSBN turning tool holder is the interface that securely holds the PSBN cutting insert, providing the necessary rigidity and stability during the turning process. These holders are designed to withstand the high cutting forces and temperatures generated when machining hard materials.

Key Components of a PSBN Turning Tool Holder

A typical PSBN turning tool holder consists of the following components:

• Shank: The main body of the holder, which is clamped into the machine tool turret.
• Insert Pocket: A precisely machined cavity that securely holds the PSBN insert.
• Clamping System: A mechanism (usually a screw or lever) that firmly secures the insert in the pocket.
• Coolant Delivery System (Optional): Some holders incorporate channels for delivering coolant directly to the cutting edge, improving cooling and lubrication.

Types of Wholesale PSBN Turning Tool Holders

There are various types of wholesale PSBN turning tool holders available to suit different machining applications. The main types include:

External Turning Tool Holders

Designed for external turning operations, these holders have the insert pocket positioned on the outside of the shank. They are available in various shank sizes and insert styles.

Internal Turning Tool Holders (Boring Bars)

Used for internal turning or boring operations, these holders have a long, slender shank to reach into deep bores. Rigidity is a critical factor for boring bars, especially for small diameters and long overhangs.

Threading Tool Holders

Specifically designed for threading operations, these holders feature a precise insert pocket to ensure accurate thread profiles.

Cut-Off Tool Holders

Used for parting or cut-off operations, these holders provide a stable platform for the cut-off insert.

Factors to Consider When Selecting a Wholesale PSBN Turning Tool Holder

Choosing the right wholesale PSBN turning tool holder is crucial for optimal performance and tool life. Consider the following factors:

Machine Tool Compatibility

Ensure that the holder's shank size and style are compatible with your machine tool's turret or spindle. Common shank sizes include square shanks (e.g., 20mm, 25mm) and rectangular shanks. At Wayleading Tools, we offer a wide range of compatible tool holders.

Insert Style and Size

The holder must be compatible with the specific PSBN insert style and size required for your application. Common insert shapes include triangular (TNGG), square (SNGG), rhombic (CNGG), and round (RNGN). Check the insert manufacturer's recommendations for the appropriate holder.

Holder Material and Construction

Look for holders made from high-quality materials such as alloy steel or hardened steel. The holder's construction should be robust and rigid to minimize vibration and deflection during cutting. Heat treatment is also important for durability.

Clamping System

The clamping system should provide a secure and repeatable clamping force to prevent insert movement during cutting. Common clamping systems include screw-on, lever-lock, and wedge-lock designs. Evaluate the ease of use and clamping force of each system.

Coolant Delivery

If coolant is required for your application, choose a holder with integrated coolant channels that deliver coolant directly to the cutting edge. This can improve tool life and surface finish. Internal coolant delivery is generally more effective than external coolant delivery.

Holder Style (Positive or Negative Rake)

The holder's rake angle affects the cutting action and chip formation. Positive rake holders are generally used for softer materials, while negative rake holders are better suited for harder materials and interrupted cuts. Choose the rake angle that is appropriate for your application. The website Wayleading Tools has additional information to help guide your decision.

Holder Overhang

Minimize the holder overhang (the distance from the turret to the cutting edge) to maximize rigidity and minimize vibration. Excessive overhang can lead to chatter and poor surface finish.

Benefits of Using High-Quality Wholesale PSBN Turning Tool Holders

Investing in high-quality wholesale PSBN turning tool holders offers several benefits:

• Improved Tool Life: A stable and rigid holder minimizes vibration and reduces stress on the insert, extending tool life.
• Enhanced Surface Finish: A rigid holder provides a more consistent cutting action, resulting in a better surface finish.
• Increased Productivity: Reduced vibration and improved cutting performance allow for higher cutting speeds and feed rates, increasing productivity.
• Reduced Scrap Rate: A stable holder minimizes the risk of insert breakage and workpiece damage, reducing the scrap rate.
• Improved Safety: A secure clamping system prevents insert movement during cutting, reducing the risk of accidents.

Where to Buy Wholesale PSBN Turning Tool Holders

Wholesale PSBN turning tool holders can be purchased from various sources, including:

• Tooling Suppliers: Many tooling suppliers specialize in cutting tools and tool holders.
• Industrial Distributors: Industrial distributors offer a wide range of industrial products, including cutting tools and tool holders.
• Online Retailers: Online retailers offer a convenient way to purchase tool holders, but it is important to choose a reputable supplier.

PSBN Turning Tool Holder Maintenance

Proper maintenance of PSBN turning tool holders is essential for ensuring optimal performance and extending their lifespan. Follow these guidelines:

• Clean the Holder: Regularly clean the holder to remove chips, coolant, and other contaminants.
• Inspect the Holder: Inspect the holder for damage, such as cracks, wear, or corrosion. Replace damaged holders immediately.
• Lubricate the Clamping System: Lubricate the clamping system regularly to ensure smooth operation and prevent corrosion.
• Store the Holder Properly: Store the holder in a dry, clean environment to prevent corrosion.

Troubleshooting Common Problems with PSBN Turning Tool Holders

Here are some common problems that can occur with PSBN turning tool holders and how to troubleshoot them:

Insert Breakage

Possible causes: Excessive cutting forces, improper insert selection, worn holder, insufficient rigidity. Solutions: Reduce cutting forces, select a more robust insert, replace the worn holder, increase rigidity.

Chatter

Possible causes: Excessive overhang, insufficient rigidity, improper cutting parameters, worn holder. Solutions: Reduce overhang, increase rigidity, adjust cutting parameters, replace the worn holder.

Poor Surface Finish

Possible causes: Vibration, improper cutting parameters, worn insert, worn holder. Solutions: Reduce vibration, adjust cutting parameters, replace the worn insert, replace the worn holder.
