Toolholder Series Increases Lathe Efficiency, Precision

Big Daishowa introduces the C3 program, an expansion of the Big Capto toolholder line, designed to increase efficiency and precision for small lathes. This turning equipment, if included in a moldmaker’s arsenal, can achieve copper and graphite electrodes, core pins, mold base components and more

The C3 series of Mega New Baby chucks has a clamping range of 0.010-0.630" with a maximum rpm of 30,000, well suited for drills, reamers, taps and finishing end mills. Ultra-slim and strong, Big Daishowa says they provide reliable gripping for even the smallest workpieces.

The Big Capto C3 square holders for turning applications come in left and right orientation. The turning application holders — C3-180-BH16R-2058 and C3-180-BH16L-2058 — are mono-block holders. Their insert clamps are tough and reliable, adding on to the already inherently high rigidity of mono-block holders. The resulting higher rigidity minimizes vibrations and movement during cutting, improving accuracy and efficiency.

The new square toolholders are available in 90- and 180-degree types. The 90-degree type offers a variety of orientations, including perpendicular to the workpiece. Its compact design also enables work in spaces that are tight or have limited clearance. The 180-degree type, meanwhile, allows the tool to machine harder-to-reach areas of the workpiece.

Due to the limited space for smaller lathes and mill-turn machines with C3 clamping systems, integral C3 turning adapters are compact and rigid with left- or right-hand units for most common turning geometries. C3 boring bar holders also are available to clamp 6-, 8-, 10- or 12-mm boring bars. All turning toolholders feature through-spindle coolant. The tool assembly device, Kombi Grip (model KG32R), can work on C3 tools outside the machine, and cleaning of internal C3 clamping units is quick and efficient using Big Capto spindle cleaner SC-C3.
