1 Scope
Routine Specification for Safe Operation of Chucks for Lathes
JB/T10332—2002
This standard specifies the safety requirements and related requirements for the safe use of lathe chucks, as well as the various responsibilities that lathe manufacturers, chuck manufacturers and users should bear. This standard is applicable to floor-type, impact or power chucks, and can also be applied to manual chucks. 2 Normative References
The clauses in the following documents become clauses of this standard through reference in this standard. These are the referenced documents of the current period, and all subsequent corrections (including revisions) or revisions are not applicable to this standard. However, the parties who have reached an agreement based on this standard may study whether the latest versions of these documents can be used. For all dated references, the latest edition applies: GB/T 9239-188 Permissible unbalance of rotor balancing quality (EVS140-1: 1986) TSO 2372: 1974 Mechanical vibration at a rotational speed of 10 to 200 r/s - Test and evaluation benchmark 3 Chuck tightening
3.1 General
If the chuck rotation speed increases, its clamping force will change even after centrifugal compensation. In the case of compensation and decompression compensation, when the chuck is externally tightened (that is, as the chuck is clamped, the claws move radially inward), the increase in rotational speed will cause the optical clamping force to increase. However, when the chuck is internally clamped, the increase in rotational speed will cause the optical clamping force to increase. Overcompensation can also have a reaction, that is, the external tightening force increases with the speed. Overcompensation is usually not allowed because repeated up and down changes in speed may cause ineffective tightening. It is necessary for the user or a pre-cutting expert to evaluate the tightening condition of the chuck. 3.2 Forces acting on the chuck 3.2.1 Overview The forces and torques acting on the chuck (clamp) through the tool can be expressed as four summaries, namely: Total axial force EFx: Total radial force (F): Total moment Ma: Total load force, unbalanced direction and torque through the tool. When the mass of some parts of the system (such as the chuck, workpiece and cutting tool) is needed, but it is impossible to measure them, their mass can be calculated according to the value (see 1): when calculating dynamic force (such as centrifugal force), the heart rate value (see Chapter 1: 3.2.2 Cutting force and cutting moment) is taken into account. The following is a simple and relatively accurate calculation method: a) Before turning the outer circle and end face (see Figure 1-Figure 3), the force N is the cutting force F, = K,tS

Figure 1 The bearing capacity of the chuck clamping the workpiece on the horizontal lathe Pre-cutting force coefficient, see Table 2, the unit is N/mm2; Cutting data, turning the outer circle between the diameter measurement, turning the end face axial measurement value, the unit is m per revolution feed, turning the outer circle axial measurement value, turning the end face radial measurement value, the unit is mTL: weakly through the estimation of power production (W) (see record A》 can also get the size of the tangential force, that is: cutting speed (m/s: =\×cutting diameter m)×rotation speed (): tangential force F=P/v:| |tt||The influence of process parameters can be considered. For example, the front part should be 10°, and for every 1° decrease, F should increase by 1%. For example, if the tool is pulled sideways, F increases by 10°, (for turning external holes or internal holes) or (for turning end faces) F or F = 0.6F (for materials that are difficult to process such as drilling): the tool resistance is lower than that of the tool. (for turning external holes or internal holes) or (for turning end faces) F (or F) = 0.23F
