RÖHM Spiral chuck Duro-M 315/2, cylindrical holder (DIN 6350, Form A), base jaws and unstepped top jaws 185592

Conventional clamping, horizontal and vertical lathes as well as milling machines, rotary tables and dividing heads. Mainly used in one-off or small series production or repair workshops for clamping rotationally symmetrical parts for turning and milling - The DURO-M is a manually operated lathe chuck with a face spiral and throughfeed. It is mainly used on conventional lathes for machining turned parts.-Chuck body (and all other components) made of steelCentred clamping via face spiralFace spiral drop-forged and highly tempered, thread flanks ground on both sidesJaws in the chuck ground for concentricityFactory-determined zero drive as precision driveThe max. permissible speed is defined so that at max. clamping force and when using the heaviest associated clamping jaws, 1/3 of the clamping force is still available as residual clamping force. The clamping jaws must not protrude beyond the outer diameter of the chuck. The lathe chucks must be in perfect condition. The provisions of DIN 6386 Part 1 also apply Clamping force according to DIN6350: The clamping force is the sum of all jaw forces acting radially on the workpiece at standstill. The specified clamping forces are guide values. They apply to chucks in a single-walled condition that are lubricated with Röhm grease F80.Scope of delivery: Chuck, chuck key, jaws. DURO-M chucks are available as 2-, 3- and 4-jaw chucks up to and including ø315mm with the lenses. All 4-jaw chucks with front mounting do not have lenses. All 6-jaw chucks also have no lenses. High concentricity up to 0.02 mmJaws are always burnishedMinimal interference contourHigh power transmissionDrip edge for coolant-The Duro-M ø315 is a manually operated 2-jaw lathe chuck with face spiral and passage ø103, base jaws and unstepped top jaws, cylindrical holder (DIN 6350, form A), ZA 260. It is mainly used on conventional lathes for machining turned parts.
