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
