Product details
The DURO-M is a manually operated chuck with a plan spiral and through hole. It is primarily used on conventional lathes for the machining of turned parts.
Technical Features:
- Chuck body (as well as all other components) made of steel
- Centrally clamped via plan spiral
- Plan spiral forged in die and high-strength treated, thread flanks ground on both sides
- Jaws ground for concentricity in the chuck
- Factory-determined zero play as accuracy adjustment
The maximum permissible speed is set so that at maximum clamping force and when using the heaviest associated jaws, one-third of the clamping force remains available as residual clamping force. The jaws must not protrude beyond the outer diameter of the chuck. The chucks must be in perfect condition. Furthermore, the regulations according to DIN 6386 Part 1 apply.
Clamping force according to DIN 6350: The clamping force is the sum of all radial jaw forces acting on the workpiece while at rest. The specified clamping forces are guideline values. They apply to chucks in perfect condition that are lubricated with Röhm grease F80.
Scope of delivery: Chuck, chuck key, jaws
Application area:
Conventional clamping horizontal and vertical lathes as well as milling machines, rotary tables, and dividing heads. Primarily in single or small series production or repair shops. Clamping of rotationally symmetrical parts for turning and milling operations.
