Precision CNC Angle Heads & Right Angle Milling Attachments

Precision CNC Angle Heads & Right Angle Milling Attachments

Beijing BOD Technology Co., Ltd. designs and manufactures high-performance CNC angle heads and right-angle milling attachments engineered to expand the machining versatility of standard machine tools. Since 2011, our ISO9001-certified factory has supplied standard and non-standard tooling attachments—including slim deep-reach angle heads, dual-output heads, high-pressure coolant-through systems, and adjustable universal swivel heads. Built for BT40, BT50, and other standard spindle interfaces, these attachments enable workshops in the aerospace, automotive, medical, and mold-making industries to execute multi-directional milling, drilling, and tapping without repositioning complex workpieces.

Premium Metallurgy and Structural Integrity Standards

To ensure long-term geometric stability and vibration damping under high radial and axial cutting forces, our CNC angle heads are built to rigid structural standards:

  • Monoblock Housings: Cast from heavy-wall QT500-7 Ductile Iron or high-strength structural alloys, then subjected to artificial aging and cryogenic stress-relief treatments to prevent thermal deformation and minimize tool chatter.

  • Precision Spiral Bevel Gears: The internal drive trains utilize Gleason ground spiral bevel gears manufactured from 20CrMnTi Alloy Steel. Carburized and quenched to a hardness of HRC 58-62 and ground to ISO Grade 4 precision, these gears maintain a transmission backlash of ≤ 15 arcmin and limit operational noise to ≤ 70 dB under full load.

  • Spindle Bearings: High-precision, preloaded P4 class angular contact bearings ensure minimal spindle runout and high rotational accuracy during continuous side milling.

Advanced Multi-Axis Solutions: Dual-Output and Universal Swivel Configurations

For complex workpiece geometries and high-throughput production lines, we provide specialized multi-axis drive designs:

  • Heavy-Duty Dual-Output Series (DK90-BT40-2X & DK90-BT50-2X): Featuring opposed, collinear spindle outputs positioned 180° apart, this series allows operators to mount two separate tool assemblies simultaneously (such as a drill on one side and a tap on the other). It supports standard CW-CW or specialized Left: CW-CW / Right: CCW-CW gear train configurations, allowing sequential operations by simply reversing the machine spindle rotation.

  • Universal Swivel Milling Series (DK90-BT50 YW & WXER): Designed with a calibrated angular housing that can be rotated and locked to custom positions, this series allows operators to perform compound-angled drilling and sloped-surface milling on 3-axis and 4-axis machines, delivering cutting torques up to 65.0 Nm.

Integrated High-Pressure Coolant-Through (CTS) Technology

Machining high-temperature alloys, stainless steels, and deep internal cavities requires efficient heat dissipation and prompt chip evacuation. Our coolant-through 90° right angle heads, such as the DK90-BT40-ER25-Z80 and DK90-BT50-ER25-Z80 models, are engineered to handle high-pressure wet machining:

  • 20 bar Pressure Capacity: Built with high-pressure rotary seals capable of handling up to 20 bar (290 PSI) through-spindle coolant (CTS).

  • Dual-Lip FKM Sealing: Utilizes dual-lip fluororubber (FKM) sealing technology to deliver cutting fluid directly through the spindle and tool centerline, flushing chips out of deep blind holes and preventing thermal tool degradation.

FAQ

Frequently Asked Questions

Common questions about our products and services.

A: Our internal drive systems utilize Gleason ground spiral bevel gears in 20CrMnTi Alloy Steel. The gears are carburized and quenched to a surface hardness of HRC 58-62 and ground to ISO Grade 4 precision. This precise design limits gear transmission backlash to ≤ 15 arcmin and operational noise under full load to ≤ 70 dB. Combined with preloaded P4 class spindle bearings, our standard angle heads provide stable torque transfer and low runout.
A: The Dual Output 90° series (such as the DK90-BT40-2X and DK90-BT50-2X) features collinear spindle outputs positioned 180° apart. By mounting two different tools at once, programmers can execute two sequential machining operations—such as face milling and side drilling—by indexing the machine spindle or reversing the axis motion. This design reduces non-productive time by completely eliminating automatic tool changer (ATC) cycle times between those steps.
A: Our coolant-through right-angle heads (including the DK90-BT40-ER25-Z80 and BT50 equivalents) support internal coolant pressures up to 20 bar (290 PSI). The housing is equipped with specialized high-pressure rotary seals and dual-lip fluororubber (FKM) sealing technology. This arrangement ensures that high-pressure cutting fluid is routed directly through the centerline of the tool, facilitating rapid chip evacuation and tool cooling during deep-cavity side drilling or milling.
