Blocks and cylinder liners

Mechanical machining of small and large engine blocks is mostly performed with the machines manufactured by the Danish AMC-Schou company and the American Sunnen company.

CYLINDER BORING, SURFACE PLANNING

Cylinder boring and surface planning are carried out using high-precision boring machines, which make it possible to achieve high machining parameters.

CYLINDER HONING

Honing (cross grinding) of cylinders is performed on a digitally controlled honing machine, which makes it possible to obtain very good technical parameters of the cylinder liner. Cylinder honing is performed using honing heads equipped with diamond stones. It also allows the honing of individual cylinder liners and non-standard block structures.

RECONDITIONING OF THE BLOCK BED (ALIGNMENT)

Reconditioning of block beds consists of reconstructing the dimensions of bores for the crankshaft supports according to catalogue data up to the nominal dimension, maintaining concentricity. A horizontal boring machine as well as a horizontal honing machine are used for the machining of crank shaft bearings.
In the case of worn crankshaft supports, we can restore them through hardfacing.

RECONDITIONING OF THE CAMSHAFT BEARING

The machining of the bushing for the camshaft in the engine blocks is performed on a horizontal boring machine. It allows to achieve the proper bore in the bearing, maintaining the perfect alignment of all bores.
