ASME B5.62M-2016 pdf download.Hollow Taper Tooling With Flange-Face Contact.
(e) Form E. Form E is similar to Form A, but it does not have keyways or orientation features. Form E is intended for high-speed machining. See Figure 1-1.3-1, illustration (e).
(/3 Form F. Form F is similar to Form E but has a reduced taper size. Form F is intended for high-speed machining. See Figure 1-1.3-1, illustration (f).
(g) Form T. Form T is similar to Form A but has modiflcations to accommodate use with stationary tools. See Figure 1-1.3-1, illustration (g).
1-1.4 Definitions
balance: the condition in which the mass centerline and rotational centerline of a rotor are coincident.
clamp set: a mechanical device for securing a shank in the receiver.
data chip: a radio-frequency identification device.
drive key: a feature of a machine tool intended to orient the toolholder in the receiver and assist in delivery of the driving torque from the spindle nose to the tool.
keyway: the part of a machine tool that receives the drive key.
receiver: the spindle or nonrotating socket of a machine. shank: a unit that fits directly into the spindle or nonrotating socket of a machine.
spindle: component assembly of the machine tool, the function of which is to accept the basic toolholder shank. spindle nose: that part of a spindle into which the shank is accepted.
1-1.5 Figure Interpretation
The Part I figures are illustrated and labeled in accordance with ASME Y14.5.
1-2 FORMS A AND C
Form A includes provisions for automatic tool change, a data chip, an orientation notch, an access hole for manual clamping, drive keyways, and through-spindle coolant supply via coolant tube. Form C is intended for manual tool change and includes an access hole for manual clamping, drive keyways, and through-spindle coolant supply.
The face contact is funda• mental For torque transmittal and for the rigidity of the hollow
taper interface.
A-2.3 TheoreticaL Speed, Torque, and Bending Moment
ASME B5.62M delines the hollow taper shank Interlace. Table A-2.3•1 offers guidelines for speed, torque, and bending moment, but these are not intended to spedf allowable maximums. Frequent operation near or above these values will result in accelerated wear and breakage of equipment. The manufacturer is responsible for supplying information regarding the capacity of Its tnolholders.
A-2.4 MateriaL and Heat Treatment
Materials for shanks and receivers should be selected and heat treated to optimize hardness, strength, toughness, and wear resistance. Ideally, the surface hardness of a shank should be slightly less than that of the receiver.
A-2.5 BaLancing
All components of the tool-holding system, I.e., the tool, toolholder. and spindle shaft, should be balanced. Toolholdcr balance may be achieved by minimal metal removal in the locations of the manufacturer’s choice. Balance should not be pursued to unnecessarily high levels.
See Figure A-23-1 for preferred balancing zones.
A-3 COOLANT TUBE
The coolant tube, shown in Figure A-3-1. serves to transfer the coolant from the spindle to the toolhulder. The coolant tube Is subject to the following considerations:
(a) The coolant tube must create a seal between the clamp set and the toolholder.
(b) As the toolhuldcr and spindle may not be perfectly aligned during a tool change, the coolant tube must have il-deg angular compliance with little resistance.
(c) The tube surface must be hardened to a minimum of 56 Rockwell C.
