Dual Output 90° Right Angle Heads (DK90-2X Double-Sided Series)

Dual Output 90° Right Angle Heads (DK90-2X Double-Sided Series)

Beijing BOD Technology Co., Ltd. designs and manufactures the DK90-2X Dual Output 90° Right Angle Head Series, specifically engineered to optimize cycle times on BT40 and BT50 vertical machining centers (VMC), horizontal machining centers (HMC), and gantry milling machines. This double-sided tooling series features collinear spindle outputs positioned 180° apart, allowing operators to mount two cutting tools simultaneously—such as an end mill on one side and a drill or tap on the other. By indexing the machine spindle or reversing spindle rotation, workshops can machine parallel internal walls or execute two sequential machining processes without initiating an automatic tool changer (ATC) cycle, significantly reducing non-productive machine downtime.

Double-Sided Spindle Outputs for Combined Machining Processes

The DK90-2X Series (comprising standard and heavy-duty series such as the BT40-2X and BT50-2X) provides a versatile double-ended drive mechanism. Spindles are configured to support standard ER collet clamping (including ER16-2X, ER25-2X, and ER32-2X models) with clamping capacities up to Ø20.0 mm, or F25 face milling arbor adapters for mounting specialized disc cutters. This layout is particularly effective for milling narrow parallel slots, machining opposite workpiece walls, or running combined processes—like side drilling on one face followed by immediate tapping on the opposite face—by utilizing simple 180° indexing or B-axis rotation.

Rigorous Gear Metallurgy and Low-Backlash Transmission

To maintain stable torque transmission and precision during multi-directional cutting, our dual output angle heads are built with precise internal gear configurations:

  • Gleason Spiral Bevel Gears: The internal drive system utilizes Gleason ground spiral bevel gears in 20CrMnTi Alloy Steel.

  • Heat Treatment & Precision: The gears are carburized and quenched to a surface hardness of HRC 58-62, then ground to ISO Grade 4 precision standards.

  • Tolerances: This precise manufacturing process keeps gear transmission backlash to ≤ 15 arcmin and dampens operational noise below 70 dB, ensuring reliable alignment and smooth rotation.

Symmetrical Monoblock Housings for Balanced Radial Forces

Machining parallel faces simultaneously or sequentially places complex stresses on a right-angle attachment. To offset these forces, our dual output heads feature a balanced mechanical design:

  • QT500-7 Ductile Iron Casting: The BT50-2X models feature heavy-wall casings cast from high-grade QT500-7 Ductile Iron, while BT40-2X models utilize high-strength structural alloys.

  • Artificial Aging & Stress Relief: Each monoblock casting undergoes artificial aging and rigorous stress-relief heat treatment to achieve structural stability.

  • Vibration Damping: The symmetrical monoblock structure is naturally balanced, helping to absorb cutting vibrations and neutralize radial forces during heavy side-milling operations, achieving torques up to 65.0 Nm on BT50 series models.

FAQ

Frequently Asked Questions

Common questions about our products and services.

A: A standard right-angle head only holds one tool, requiring a full automatic tool changer (ATC) cycle if you need to switch from a drilling to a tapping tool. The dual-output 2X series holds two distinct tools simultaneously (spaced 180° apart). This allows operators to complete sequential tasks—such as side-milling with spindle A and then chamfering or tapping with spindle B—simply by indexing the machine spindle, completely eliminating tool-changing downtime.
A: To accommodate different cutting tool designs, the dual-output series is available in two distinct rotational configurations. Customers can choose standard CW-CW (clockwise-clockwise) dual rotation, or a specialized Left: CW-CW / Right: CCW-CW (clockwise-counterclockwise) gear train configuration. This provides programming flexibility when utilizing right-hand and left-hand cutting tools on opposite faces of the workpiece.
A: The DK90-BT40-2X and DK90-BT50-2X series support several standard interfaces to match varying machining needs. These include ER collet spindles (ER16-2X, ER25-2X, and ER32-2X), which allow tool clamping capacities up to Ø20.0 mm. For side slotting and face milling operations, select models are available with F25 face-milling arbor adapters, which are suitable for securing specialized indexing disc cutters.
