43A/B/F BTA Solid Carbide Drill Head Series - Extra-Large Diameter with Multiple Connections - Xunxian Industrial

Product Features & Advantages

Multiple Connection Systems: Three specialized configurations cater to different machine requirements—43A for standard single-thread applications, 43B for enhanced stability with four-thread connection, and 43F for high-torque flange-mounted applications.
Industry-Leading Diameter Range: With capacity from 60 mm to nearly 370 mm, the 43 series covers the broadest diameter range available in modular BTA drill heads, eliminating the need for custom tooling in most extra-large diameter applications.
Precision Gasket Adjustment System: Advanced gasket technology enables precise diameter tuning within the massive range, allowing fine adjustments to meet exact specifications without replacing entire components.
Modular Component Design: Replaceable carbide blades and guide strips minimize maintenance costs by enabling targeted replacement of only worn components rather than the entire assembly.
Heavy-Duty Construction: Engineered with reinforced alloy steel and premium solid carbide inserts to withstand the extreme forces encountered in large-diameter deep hole drilling.
Optimized Chip Evacuation: Specially designed blade geometry ensures efficient chip flow in BTA systems, critical for preventing chip jamming during large-diameter operations.
Rigid Stability: Multi-thread and flange connection options provide exceptional rigidity, minimizing vibration and ensuring straight, accurate holes even at maximum diameters.

Installation and Setup Procedure

Configuration Selection: Choose the appropriate model (43A, 43B, or 43F) based on your machine's connection requirements and application demands.
Diameter Determination: Calculate the exact required diameter for your application within the 60.00-368.99 mm range.
Gasket Selection: Select the correct gasket combination from the provided adjustment chart to achieve your target diameter.
Pre-Assembly Inspection: Thoroughly inspect all components—blades, guide strips, gaskets, and body—for any damage or contamination.
Component Assembly: Assemble the drill head with selected gaskets, ensuring proper placement and orientation of all components.
Connection Preparation: Prepare the machine connection point according to your selected model (thread cleaning for 43A/43B, flange surface preparation for 43F).
Tool Mounting:
- 43A/43B: Carefully thread the head onto the machine spindle using appropriate lifting equipment.
- 43F: Align the flange and secure with the specified bolt pattern and torque sequence.
Diameter Verification: Use precision measuring equipment to confirm the assembled diameter meets specifications.
Machine Parameter Setup: Configure speed, feed, and coolant parameters based on diameter, material, and depth requirements.
Test Run & Adjustment: Conduct a test run and make final adjustments to parameters or gaskets as needed.

Frequently Asked Questions (FAQ)

Q: How do I choose between 43A, 43B, and 43F configurations?
A: Select based on your machine connection and application requirements: 43A for standard single-thread applications, 43B for enhanced stability in demanding conditions, and 43F for high-torque applications requiring maximum rigidity.
Q: What is the maximum depth capability for the 43 series?
A: Depth capability depends on diameter, material, and machine power. Generally, the 43 series can achieve depth-to-diameter ratios of 30:1 to 50:1 with proper setup and parameters.
Q: How precise is the diameter adjustment with the gasket system?
A: The gasket system provides adjustment accuracy within ±0.03 mm for diameters up to 200 mm and ±0.05 mm for diameters above 200 mm when properly installed.
Q: What lifting equipment is required for installation?
A: Due to their size and weight (up to 150 kg), proper lifting equipment is essential. We recommend overhead cranes or specialized tool handling equipment rated for the specific weight of your selected configuration.
Q: Can components from one 43 configuration be used on another?
A: Blades and guide strips are generally interchangeable within the same diameter range, but connection-specific components (threads, flanges) are unique to each configuration.
Q: What is the lead time for custom configurations or large orders?
A: Standard configurations ship in 3-4 weeks. Custom configurations or large orders typically require 6-8 weeks for engineering and manufacturing. Rush services may be available for critical needs.
Q: Do you provide on-site installation and training support?
A: Yes, for large orders or complex installations, we offer on-site technical support, installation assistance, and operator training to ensure optimal performance and safety.
