Fully Automatic Centerless O.D. Stone Lapping Machine
(Infeed and traverse cut methods)
for machining of O.D. of steering rack bars and piston rods for shock absorbersStandard application range : OD 20 - 50 x Length 800 mm
-Machinable length : Max. L 510 mm
ASM-700
Application
1) Steering rack bar
2) Piston rod for shock absorber
Main Features
- Originally developed for machining rack bars, this infeed-type stone lapping unit is ideal for workpieces that are long and have shapes that are difficult for thru-feed machining
- Equipped with our original AEROLIDE® stone lapping unit.
Its oscillation mechanism with stable amplitude also realizes complete elimination of secondary vibrations caused by the inertia balance mechanism. - Workpieces are positioned by the stopper of the infeed system, while the stone lapping unit employs a traverse cut machining method of the specified machining width. Additionally, changeover is not required for automatic random machining of workpieces of differing lengths.
