Big Daishowa Toolholder Increases Precision for Lathes

Big Daishowa has introduced the C3 program, an expansion of the Big Capto toolholder line, designed to increase efficiency and precision for small lathes.

The C3 series of Mega New Baby chucks has a clamping range of .010-.630" with a maximum rpm of 30,000. According to the company, these make excellent choices for drills, reamers, taps and finishing end mills. Ultra-slim and strong, 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 to the high rigidity of mono-block holders. The resulting higher rigidity minimizes vibrations and movement during cutting, Carbide Turning Inserts improving accuracy and efficiency.

The new square tool holders are available in 90-degree and 180-degree types. The 90-degree type offers a variety of orientations, including perpendicular to the workpiece. Its compact design also enables for work in spaces that are tighter or have limited clearance. The 180-degree type, meanwhile, enables 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 both 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. Big Daishowa offers the Kombi Grip (model KG32R) tool assembly device to 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.DCMT Insert
