HONING & BORING WITH DUMMY HEAD


However cylinder horning, boring, and measurement have performed to the single engine block, when cylinder head is attached and head bolt is actually assembled, numerical value and form of the engine block will be changed from modification or distortion of each part in 0.01mm degree.
Therefore, in case cylinder horning and boring are performed strictly, the statement of the engine block that the head gasket and the cylinder head is attached, have to be reproduced by assembling dummy head and gasket.
Thereby, the processing accuracy of horning and drilling, and the accuracy of subsequent engine assembly will be improved remarkably.

PLATEAU HONING


In general horning, crosshatch pattern is grooved to the surface of the wall of the cylinder to remaining oil for the smoother piston movement.
However, in this method, roughness of the cylinder wall surface becomes larger and will not fit with the piston ring, but will become resistance of piston movement rather.
Plateau horning of TOMEI can reduce friction loss remarkably by grinding off only the apex of the grooves from the crosshatch, making the surface of the cylinder wall flat while keeping oil between the grooves.
