Pratt Burnerd has an extensive range of multijaw manual chucks manufactured from the highest quality materials. Products include:
Standard accuracy chucks have bodies manufactured from high-quality SG iron with component parts manufactured from high-quality alloy steel and heat treated for optimum performance and durability.
Super precision chucks have a repeatability of 0.03mm TIR guaranteed. A wide range of chuck adaptors is available to meet most spindle noses. Hardened base and reversible top jaws are available as an option.
Griptru chucks are often used in grinding operations and the 6 jaw Griptru allows the gripping of thin-walled components with minimum distortion. A proven micro-adjustment device on both 3 and 6 jaw chucks permits concentricity to be adjusted to within 0.005mm TIR.
The metric Independent chuck is manufactured from SG iron and is the most economical chuck for turning one-off components and short runs. All screws, bearings and reversible jaws are manufactured from steel.
Large 3 jaw scroll chucks can be supplied with recess mount or finished to suit most spindle noses and also offered with a large bore. Hardened base and reversible top jaws are an option.
The Large Independent 4 jaw chuck has body, screws, bearings and jaws manufactured from high-quality steel. It can be machined with mounting holes and recesses to suit the spindle nose.
All Pratt Burnerd's Independent and Scroll chucks can be supplied with larger through bore for larger components, typically for oil and gas applications, upon request.
