Our heavy-duty lathe chucks are standard with diameters as 1250, 1400, 1600, 1800, 2000 and 2500mm. They are avaiable with two types of connections to lathes or other machines, one is direct mounting type which allow the chucks to fit lathe spindle noses of A2-15, A2-20, A2-28 specifications recognized internationally; the other is in-direct mounting type which fit the chucks via an adpator plate to the lathe spindle noses or other machines, such as apipe cutting machine or awelding positioner.2. Thes heavy-duty lathe chucks have their chuck body made of cast steel, not cast iron, so they have higher strength in operation compared with chucks made of gray cast iron or nodular cast iron. The chuck usually has four pieces of jaws, which can be either embedded in the chuck base or independent chuck jaws (also called boring mill jaws), depending on the weight of the workpiece this chuck is used to clamp. The chuck can have 4, 6, 8jaws or other numbers of jaws on requests. In case of boring mill jaws being needed to be fitted on the chucks, we can arrange in the boring mill jaws with mechanical clamping force boosting devices such as mechanical clamping forces boosting screws, or just aset of gear sectors combined with pinion gear for driving the screw rod by engaging with the gear sectors, thus the operator can use one-man power to perform clamping of huge workpieces which weight can be up to hundreds of tons.3. Usually these large chucks are fitted on lathes as workholdings, but also frequently they are used on other type of machines, especially on pipe handling machines such as welding positioners, pipe cutters, pipe welding machines. In cases that they are used on pipe handling machines, they can have large bores with diameters such as 500mm, 630mm, 800mm etc. decided by customers' actual requirements.4. These heavy duty chucks can always be customized. They can not only be fitted on anew machines, but also can be fitted on arefurbished machine.Diameter, mmD1D2D3H1HLhkZ-dDirectIndirect1000540-58051015032415030708-M201250285285.78330.228018040018023808-M22/M241400285285.78330.228018040018023808-M22/M241600285285.78330.228018040018023808-M22/M24300-380300330552200300804-M361800285285.78330.228018040218023808-M22/M24300-380300330552200300804-M362000285285.78330.228018040218023808-M22/M24300-380300330552200320804-M362500410412.78463.640020042220025808-M30450-560360390612200350804-M42
