Special-purpose machine tools for piston rings and camshafts are alien to the other types of machine tools. These machines are designed to lathe-turn and grind the work to the contours of ellipses and perfect circles and polish for finishing according to the theory of utmost pursuance. Because of irregular contours, high technological capability is required for the structures and functions of these machines and their controls. Also, these engine parts are requested to help the reduction of fuel consumption and the improvement of emission gas cleanness and durability by improving their contours and functions.

Aiming at the reduction of manufacturing cost and stabilization of product quality by appropriately utilizing operators and saving labors, the systematization of manufacturing lines by fully automating them with various automatic units is being accelerated. |
|
To realize the assured in-process quality, it is requested that the complicated special-purpose mechanism of each unit should be simplified and machines should be developed by combining customized CNC. |

●Multiple workpieces … Machining many work at a time |
|
To improve the productivity and reduce the cost to the maximum extent, a machine that is capable of machining different processes at the same time in parallel is required. |
|
To satisfy high-level requirements for higher productivity, higher quality and lower cost, the work supporting system is the most important element. Based on various hands-on work supporters and internationally obtained information, KATAOKA Engine proposes the optimum work supporters to deal with high-load machining and unstable machining. |

To maintain high-precision machining at a high level, it is essential to improve the spindle and slide systems to be high in precision and establish accurate pressurization technology. Oil-film lubrication,air film and accurate pressurization technology can maintain an appropriate and stable clearance and pressure and clear errors in installation parts. Therefore, hydrostatic or pressure-controlled spindles and slides can realize rotational and translatory precisions higher than the precision of components, and realize high-grade perfect-circle and non-perfect-circle machining, required surface roughness,etc. When the reliability (Cp value) of machining precision is improved, any error in machining and measurement precisions can be eliminated by employing an offset system applied with the leveling |
