4V Parallel Blocks
4V Parallel Blocks with a flat side
2V Parallel Blocks with tightening clamps
These blocks are used for calibrations in several levels of precision, and are thus available in various tolerances regarding planarity, normality, and face parallelism:
- Top precision +/- 0.005 (X32C13 UNI 4047 hardened steel, hardness HRc 48/50)
- High precision +/- 0.01 (X32C13 UNI 4047 hardened steel, hardness HRc 48/50)
- Standard precision +/- 0.02 (G26 UNI 668 cast-iron, hardness 200 ÷ 220 HB and slow stabilization pearlitic structure)
Dumping is made in order to avoid after-tempering cracking. V-cuts are symmetrical to the center, parallel to the side faces and perpendicular to the head.
4V Parallel Blocks with an I section
4V Parallel Blocks with a flat side and an I section
1 V Parallel Prisms
These blocks can be manufactured at different levels of precision regarding planarity, normality, and face parallelism:
High precision +/- 0.01
Standard precision +/- 0.02
In both cases, the material being employed is G26 UNI 668 cast-iron, with a hardness of 200 ÷ 220 HB and a pearlitic structure, oven-annealed or aged either naturally or in a thermal shock oven for slower stabilization.
Dumping is made in order to avoid after-tempering cracking. V-cuts are symmetrical to the center, parallel to the side faces and perpendicular to the head.
Parallels for cranks
These pieces are manufactured at a high level of precision, with a tolerance of +/- 0.01 pertaining to planarity, parallelism and normality of the V cuts, which are parallel to the support surface.
The material being employed is G26 UNI 668 cast-iron, with a hardness of 200 ÷ 220 HB and a pearlitic structure, oven-annealed or aged either naturally or in a thermal shock oven for slower stabilization.
Parallels with cutter equalizer
These elements are only built at the highest level of precision, with tolerances of +/- 0.005 (pertaining to planarity and parallelism).
The material being employed is G26 UNI 668 cast-iron, with a hardness of 200 ÷ 220 HB and a pearlitic structure, oven-annealed or aged either naturally or in a thermal shock oven for slower stabilization, while the knife is made of X32 C13 UNI 4047 hardened stainless steel, with a hardness of HRc 48/50.
The base is rectified damask steel, while the knives are rectified and whetstone-honed on the edges.
