Koma Precision Inc. now offers live tools for CNC lathes from the Italian manufacturer Alberti, for Doosan, Feeler, Hyundia Wia, and Samsung Machine Tools. Designed and manufactured to the OEM specifications, Alberti live tools enhance the performance of CNC lathes. Alberti live tool housings are machined from solid blocks of spheroidal cast iron to achieve tight tolerances. All bevel gears used are spiral Gleason gears made from aerospace/military grade steel. Precision ground spindle bearings and high performance seals result in high accuracy, rigidity, stability and durability in turning operations.
Currently, Koma Precision live tool line accommodates Doosan's Puma machines, Feeler's HT's and FT's machines, Hyundai Wia's L230, L300, L400, LV500, L600, L700, LV800, LF1600, LF1800, LF2000, LF2500, and LV1100 machines, and Samsung's SL-20, SL-25, SL-35, SL-45, and SL-65.
Along with live tools for Doosan, Feeler, Hyundia Wia, and Samsung Machine Tools lathes, Koma Precision stocks a range of standardized live tools for Okuma, Mori Seiki, Nakamura-Tome, and other major builders. Koma Precision live tool offering includes high-speed tooling, high pressure thru coolant, axial tools, radial tools, dual output radial tools and universal tools. Straight and offset units, modular quick-change systems and tapping quick-change holders are also available. In addition to Alberti live tooling; Koma Precision carries a range of precision Alberti Angle Heads for machining centers.
"Koma Precision Inc. and Alberti share a commitment to providing quality products that maximize the performance of machine centers," stated John Arnestad, regional sales manager, Koma Precision. "Koma's expert staff draws upon years of experience to help you choose the best live tools for your job. The better you are at choosing the right tools, the more efficient your process becomes."
Related Glossary Terms
- centers
centers
Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.
- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
- 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.
- tapping
tapping
Machining operation in which a tap, with teeth on its periphery, cuts internal threads in a predrilled hole having a smaller diameter than the tap diameter. Threads are formed by a combined rotary and axial-relative motion between tap and workpiece. See tap.
- turning
turning
Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
