Röhm Three-jaw lathe chuck, steel, short taper DIN 702-3

Short description: The DURO-M is a manually operated chuck with a scroll 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; concentric clamping via scroll; scroll forged in a die and heat-treated, thread flanks ground on both sides; jaws ground for runout in the chuck; factory-determined zero play for accuracy; 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 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 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. Areas of application: Conventionally clamping horizontal and vertical lathes as well as milling machines, rotary tables, and dividing heads. Mainly in single or small batch production or repair workshops. Clamping of rotationally symmetrical parts for turning and milling operations. Advantages: High runout accuracy up to 0.02; jaws generally blued; minimal interference contour; high force transmission; drip edge for coolant. Additional information: The Duro-M Ø125 is a manually operated 3-jaw chuck with a scroll and through hole Ø32, drilling and turning jaws, bayonet mount (ISO 702-3/DIN 55027), KK 4. It is primarily used on conventional lathes for the machining of turned parts.
