Technical support.

High precision honing operations, even within 1 µm, can be achieved by untrained operators after minimal instruction (½ day).

Achievable surface finish of Ra 0,025 µm in hard or soft materials with the same hone.

Repeatability within 1 µm even during manual honing operations.

All honeable materials can be machined with the same hone.

Exceptional tool life.

Expandable hones starting at Ø 0,6 mm.

Due to the nature of our hones and our revolutionary micrometric expansion system (manual or with electronic control), holes with an interrupted cut or with keyways can be honed without difficulty. Two separate aligned holes, even with different diameters can be honed at the same time.

No deformation of thin walled workpieces.

Extremely short preparation time and quick tool changeover.

Hones, apparatus and machines require minimum maintenance.

All hones above Ø 3 mm can be reutilised after recoating.

Special hones manufactured according to specifications.

Exceptional flexibility.

Outstanding price / performance relationship.

Services and advises from experienced personnel.

PEMAMO SA is founded in 1988 as a manufacturer of honing machines and tooling for high precision.

Following the development by a talented mechanical engineer in the 70’s, a radical new method for expanding the hone was developed.

PEMAMO SA has built a network of qualified agents, complimentary in their field of high precision. The collaboration of its 30 agents in 25 countries allows PEMAMO SA to develop machines and honing tools to achieve incomparable precision.

The success of PEMAMO SA is based on the development of our specific expandable honing system. The company offers today a wide range of products. It consists of tools, apparatus, automatic or semi-automatic machines to meet the lower micron tolerances.
