Mandrel (Hydraulic/Slide Key Type)
For chucking ring-shaped products
during measurement/machining!
- Easy operation with a single wrench!
- Runout accuracy is less than 5µm (with Master ring)
- 95% reduction of centering time
- High accuracy by inexpensive mechanism (runout accuracy 5 µm or less)
- The same main unit can be used for a wide variety of products
“Amazing Ideas / Facts!”
Easy operation with a single wrench reduces the time required for centering adjustment and realizes high-precision clamping, regardless of operator's skill.
Adopting to a wide variety of products (different shape of workpieces, equipment, etc).
By changing of collets, it can be used for a wide range of diameters.
“Easy,” “Highly accurate,” and “Flexible” at the same time.
Excellent runout accuracy on chuckingGood !
Reduced centering adjusting timeGood !
POINT!
Easy and highly accurate: The same accuracy can be achieved by any operators!Excellent !
Background / Point for Development
Background
- In gear-processing, it was difficult to accurately measure workpieces during the machinings /measurements, and adjusting the centers of workpieces was time-consuming, required skilled operators.
The need for easier operation while still stable and high precision clamping were possible, not depending on operator's ability.
Point for Development
- The mandrel can be operated with a single wrench, greatly reducing the number of steps, required for the centering.
- The consistent runout accuracy, regardless of the operator's skill.
- Compatible in a wide range of diameters for multiple product types, by simply replacing collets.
- The often-demanded “Small-diameter type” is also available.
- ‘Easy operation,’ ‘high accuracy,’ and ‘flexibility’ are realized.
Examples of Utilization
