the bronze sculpture came to the forefront during the Renaissance period

Once again, the bronze sculpture came to the forefront during the Renaissance period when they were popular. The turret-for-bronze knife is not the demolition of bronze knife, but replaced bronze sword and bronze knife folder with the NC drilling machines, etc. are still using turret bronze knife library.
Bronze knife disc-bronze knife library disc bronze knife library was not in coils, bronze knife vertically aligned along the disk (including radial to take the bronze knives and axial take bronze knife along the disk radial arrangement, or an acute angle arranged in the form of a bronze knife library. structure is simple, compact, used more often, but the bronze knife single-ring arrangement, space utilization is low. see Figure 2.7a). c1. The industrial revolution which followed four centuries later provided the tools necessary for creating bronze sculpture. If we increase the capacity of the bronze knife library must increase the outer diameter of the bronze knife library, then the moment of inertia is also increased accordingly, choose bronze knife sports a long time. The number of bronze knife is generally not more than.
 The bronze knife was ring arranged in a bronze knife library space utilization is high, but it must make to take the bronze knife agencies, applies to the machine tool space restricted Bronze knife storage capacity and large occasions. Lots of bronze sculpturesprang up in the city of Paris. The dual-disc structure is two smaller capacity bronze knife library placed to the spindle on both sides, more compact layout, number of Chu bronze knife is also a corresponding increase, applicable to small and medium-sized machining centers. Automatically change the device and its control of bronze knife b) Figure 2.7 disc bronze knife library (3) chain bronze knife libraries, including single-chain and chain link can be in the form of a variety of changes, see Figure, the basic structure shown in Figure 2.8d. Features: For the bronze knife storage capacity of the occasion, the space occupied by small, generally applies to the number of bronze knife in 30.120.
Only increase the length of the chain to increase the number of bronze knife, circumferential speed can not increase its moment of inertia as increase in the amount of disc unlike the bronze tool magazine.
