ASME B5-60:2002 pdf download WORKHOLDING CHUCKS: JAW TYPE CHUCKS Incorporating ASME B5.60.1 and ASME B5.60.4
1 INTRODUCTION
This American National Standard establishes technical requirements for workholding chucks used primarilyin turning operations. It covers jaw type chucks whethermanual or power-operated.
2 SCOPE
This Part of the ASME B5.60 standard covers theGeneral Description and Definitions of Terms relatedto jaw type workholding chucks.
3 TYPES OF JAW CHUCKS BY DESIGN
selfcentering chuck: a chuck in which all jaws moveto or away from the workpiece and maintain onecommon center.
compensating chuck: a chuck in which jaw(s) moveto or away from the workpiece without altering theposition of the workpiece.
independent chuck: a chuck in which each individualworkholding jaw is moved to or from the workpiecewithout disturbing the position of any other jaw.
An example of a power chuck assembly is presentedin Fig. 1.
4 METHODS OF ACTUATION
manual: a chuck that is actuated by hand with theaid of human energy (e.g., by means of a chuckwrench).Refer to Fig.2.
power: a chuck that is actuated by means of pneumatichydraulic, or electrical energy, etc. Refer to Fig. 3.
5 DEFINITIONS
actuafor: a component within a chuck’s body, usedto operate the chuck’s mechanism, such as a wedge.lever,scroll,etc.
base jaw:see master jaw.
centrifugal force: force generated by rotation thattends to move all parts away radially from the axisof rotation of the chuck.
chuck adapter: interface between the machine and thechuck. It can be a separate component or integral tochuck body.
chuck body: that part of the chuck that contains theactuator and master jaws.
clamping cylinder: device that actuates the chuckthrough a draw bar or draw tube with the aid ofpneumatic or hydraulic energy.
clamping force: algebraic sum of the individual radialforces applied by the top jaws on the workpiece.
clamping torque: product of the clamping force.clamping radius, and the coefficient of friction betweenthe top jaw(s) and the workpiece
countercentrifugal chuck: a chuck in which there isa system that permits compensation for the loss ofclamping force due to centrifugal force.
draw bar: a bar or tube that connects the clampingcylinder to the chuck’s actuator to transmit the inputforce to the chuck.
dynamic clamping force: actual clamping force whenthe chuck is rotating.
hysteresis. change in static clamping force after thechuck has been rotated at working rotational speedwith a constant input force.
indicating band: a diameter on the chuck body desig-nated for measuring runout of a chuck.
input force: force acting on the chuck’s actuator.
applied from an external energy source.
input torque: torque acting on the chuck’s actuator,applied from an external energy source.
master jaw: radial moving part within the chuck bodyto which the top jaw is mounted
maximumrotational speed.maximum rotationalspeed in RPM specified by the manufacturer for a
