High performance special inside diameter boring equipment : Salient feature
The high accuracy special inner diameter boring equipment that Nomura Plating has, is not the conventional counter type boring equipment, but the equipment which carries out high accuracy controlled boring processing supported by linear motor controlled processing equipment. This high accuracy processing enable to give seamless boring processing in the center portion. Because of this seamless property, it becomes possible to manufacture balanced roll, even used in high rotation speed.

Salient feature ② | Realize to obtain high balance accuracy of large size roll used in high rotation |
Salient feature ③ | Super precision boring processing by linear motor control employment |


High performance special inside diameter boring equipment : Salient feature-2
High accuracy special inner diameter boring can process large size machining including maximum inner diameter:φ1,300m, face length: 11,000, outer diameter: 1,520mm, weight: up-to 25t. Large size roll is generally used in low rotation, but this high accuracy special inner diameter boring equipment can produce large size roll to keep its balance if used in high rotation speed. The Company has the supply experience to have processed extremely high accuracy boring processing of cylindricity of 50μm to nip roll having inner diameter: φ580 x face length: 5,765mm. This equipment can produce uniformity of nip by the uniform thickness, and also can reduce the temperature non-uniformity when heated and cooled.
