DURO-NCSE FlexMaximum Flexibility for minimun set-up times

The RÖHM DURO-NCSE Flex power chuck is characterized by its fast and extremely easy way of changing jaws and clamping tools. Mandrels, collet chucks or face drivers can be changed in no time without taking the chuck from the machine. This chuck is especially suitable for machining with frequent clamping tool changes, since only the attachment system have to be changed with a quick change system.

DURO-NCSE Flex Flexible and easy to handle

Customer advantages:

- Base chuck with jaw quick change system

- Easy insertion of exchangeable components in 5 steps 1. Remove chuck jaws with jaw quick change system 2. Insert protection jaw 3. Attachment system 4. 60° rotation - draw bar is connected via bayonet 5. Fix mounting screws

- Precise centering of exchangeable component via centering taper- No complete clamping change necessary- Due to very short set-up times, set-up costs are clearly reduced

• Individual jaw unlocking for moving, changing and turning of jaws

• High workholding accuracy and gripping force

• Power transmission via taper bar system

• Low loss of clamping forces due to low jaw weight and stabilisation of taper bars in chuck body

• For very high speed

• Made of steel, all wearing parts hardened and ground

• All parts completely case hardened

• Base jaw guide lubricated

• The toothing of the wedge bar always is in full contact with the jaw

Base chuck DURO-NCSE FlexThe base chuck DURO-NCSE forms the basis of the „Flex“ system

DURO-NCSE Flex with collet chuck KZZT / KZZT-A

• Flexible adjustment to the clamping diameter by TopGrip • Deformation-sensitive as well as thin workpieces can be clamped radially from the outside with high clamping force by enclosure of the collet • Full through-hole of the clamping diameter for the machining of bars, square and hexagon profiles can be clamped with suitable collets • Suitable for high speed, low centrifugal force development, therefore high and constant clamping forces

DURO-NCSE Flex with mandrel ABSIS

• Flexible and fast adjustment to the clamping diameter by segmentsleeves• Deformation-sensitive as well as thin workpieces, especially sleeves can be clamped by elastic widening of the extension sleeve. The clamping occurs radially from the inside.• Draw-down effect• High axial accuracy, concentricity and repeatability• Good clamping possibilities for shortly clamped workpieces
