NUT
ER // NUT
ER nut is in the norm DIN6499/ISO15488
It assembles with form A & form B ER collet in the norm of DIN6499/ISO15488
Nut is one of the main parts for collet chuck
It tightens the collet with tool on the collet chuck
However, it is never easy to produce an accurate one
There are some points to notice:
-
Materia
- It will easily crack if produce the nut with carburizing material
- YAMAKEN produce ERM nut & ER nut with through hardening steel
- YAMAKEN produce SGER nut with bearing steel
- It will not crack easily with such material
-
Roundness of nut
- Nut with poor roundness will reduce the accuracy when assemble with the chuck
- YAMAKEN produce the nut with roundness 0.002mm
-
Concentricity
- Nut with poor concentricity will reduce the accuracy when assemble with the chuck
- YAMAKEN produce the nut with concendricity 0.002mm
-
Tolerance of internal thread
- Accuracy of nut at thread part in the norm DIN6499/ISO15488 is ISO6H
- YAMAKEN produce it ISO5H
-
Assembly accuracy of nut with chuck and collet
- SGER nut + AA grade ER collet assembly runout 0.003mm @3*d
- ERM nut & ER nut + AA grade ER collet assembly runout 0.005mm @3*d
- SGER nut + ER collet assembly runout 0.006mm @3*d
- ERM nut & ER nut + ER collet assembly runout 0.010mm @3*d
