CMK12 Adjustable Multi-Spindle Head: Versatile 2-Spindle Machining

CMK12 Multi-Spindle Head is a highly adaptable, two-spindle solution designed to double your drilling and tapping efficiency. Engineered for maximum flexibility, this unit allows operators to machine two holes simultaneously, drastically reducing cycle times in diverse production environments.

Fully Adjustable 360° Positioning System

The CMK12 model provides exceptional setup flexibility through its unique mechanical configuration, allowing you to tailor the tool to complex workpiece geometries without needing custom-built heads:

• Adjustable Center Distance: By simply loosening the securing bolts located beneath the head, operators can easily adjust the center-to-center distance between the two outputs to match the required hole pattern.
• 360° Independent Rotation: Each of the two outputs is capable of rotating a full 360 degrees circularly on its own axis. A built-in circular adjustment scale ensures precise and repeatable positioning.
• Upper Body Linear Alignment: Once the optimal distance between the outputs is set, if the spindles do not sit linearly relative to the machine table, the entire upper body of the multi-spindle head can be rotated to achieve perfect linear orientation.
• Morse Taper Drive: As a standard configuration, the primary drive is powered through a robust Morse taper connection, efficiently transferring torque from the machine spindle to the internal gear mechanism.
