Study and manufacturing of a set of blades by EDM thread

Perilan World manufactures a wide variety of parts that are machined on both lathes and milling machines. However, in this case, EDM wire was required to manufacture these parts and they do not have this technology.

Project description

After developing a geometric study of the parts that make up the project, we have developed a suitable process for their manufacture in Oteitza. Subsequently, using the KONDIA HS-1000 milling machine, parts and their tooling were manufactured using high speed.

Given the role of the parts, they were hardened and tempered to achieve the required level of hardness, specifically 58 HRC. In order to achieve a defined geometry, the ONA wire EDM machine had to be used to finish the parts not machined with revolving tools.

The parts made were Upper_1_blade (5 pcs), Lower_1_blade (5 pcs), Anvil_1 (5 pcs), Former_1 (3 pcs), Upper_long_blade (5 pcs), Former_2 (3 pcs), Upper_long_blade (5 pcs), Shaper_2 (3 pcs), Upper_Long_2_Knife (5 pcs), Lower_2_Knife (5 pcs), Anvil_2 (5 pcs), Shaper_1_Long (3 pcs).

The main difficulties have been the small size of the pieces, the necessary hardness and their design.
