Mega 12DS Power Chuck for Heavy-Duty End Milling

BIG DAISHOWA has announced a new addition to the MEGA DOUBLE POWER CHUCK lineup for heavy-duty end milling: the MEGA 12DS. Designed for trochoidal milling with anti-vibration end mills, the MEGA 12DS series features high rigidity and gripping strength and is available in BBT30/40, HSK-A, C for metric and BCV40 for inch.

The Mega Double Power Chuck system features an expanded contact diameter of the nut to the flange, which provides the highest rigidity—as if the chuck and nut were one solid piece. This superior rigidity ensures heavy duty machining without chatter.

The MEGA Series high-speed milling chucks are precision ground and balanced, with all components specifically designed for high-speed applications. Like the full MEGA DOUBLE POWER CHUCK lineup, the new MEGA 12DS series enables max of 30,000 RPM.

A secure, jet-through coolant supply enables improved surface finish, smoother chip evacuation, extended tool life, and better cooling and lubrication of tools.

Related Glossary Terms

  • chatter

    chatter

    Condition of vibration involving the machine, workpiece and cutting tool. Once this condition arises, it is often self-sustaining until the problem is corrected. Chatter can be identified when lines or grooves appear at regular intervals in the workpiece. These lines or grooves are caused by the teeth of the cutter as they vibrate in and out of the workpiece and their spacing depends on the frequency of vibration.

  • chuck

    chuck

    Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.

  • coolant

    coolant

    Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.

  • gang cutting ( milling)

    gang cutting ( milling)

    Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.

  • milling

    milling

    Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.
