BMT Tool Holders

In the tooling phase, tool holders are the main facet that used to connect the machine tool to the tooling. Their mounting styles are all different according to the interface of the machineries. Their mounts can range from HSK tool holders, VDI mount, or the dated R8 styles. BMT tool holders are very famous and practical for their advantages. In comparison, when people use CNC mill-turn lathe, there are two mounting options for live tool holders, VDI or BMT (Base Mount Tool), and BMT is the latest technology for mill-turn machine and it is a better solution with rigidity. During the mounting of the tool holder to turret, operators can use 4 screws to tighten the tool holder, which is located and secured with locating keys present on the turret face, and these keys eliminate the need for indicating the tool holder to straighten it.
 
On the other hand, the former one, VDI, has been recognized the most broadly adopted on turret worldwide since it has been released for over decades, and the tool is held in place by a mating part with teeth that is housed inside the turret unit. VDI tool holder needs to indicate the straightness during mounting, by twisting the screw to verify the precision value, and one can adjust the straightness.

Holding strength

Among the tooling family, all kinds of machine tools would be composed and installed with at least a tool holder, or tool holders. Turning machine, milling machine, machine center, drilling machine, boring machine, and even tapping machine are all designed with tool holders and can clamp and un-clamp tools so that the worn out cutters can be replaced by the new one or be re-shaped again for future machining tasks. In the machine tool sector, a machine taper is a system for securing cutting tools or tool holders in the spindle of a machine tool or powered tools. In principle, a male member of conical form fits into the female socket, in which there is a matching taper of equal angle. Nearly all machine tool spindles, and many powered tool spindles, are designed with a taper as their primary method of attachment for tools. Even on many conventional and advanced drill presses, handheld drills, and turning machines, even they have chucks; the chuck is still attached by a taper as well. On the other hand, for the drills, drill presses, and milling machines, the male member is the tool shank or tool holder shank, while the female socket is integral with the spindle units.
 
This machining method could be done on different directions. In the metalworking sector, milling process of machining centers covers a wide variety of various operations and ranges a wide scale from single tiny parts to heavy and large milling operation tasks. Double column plus 5 axis functionality is one of the very practical solutions to solve the machining vibration issues while improve the accuracy at the same time. The double column machining centers are generally classified into two types: either fixed column or moving column. The former is the design that both columns stay where they are without the possibility of moving, and the latter allows for another axis to be born, thus greatly improves the convenience of machining. CNC 5 axis Double column machining center is a highly developed machine tool that can deal with many kinds of machining tasks, after the development of the 5 axis, the development of this specific type of machine tools goes well in the industry, and after that, machine centers are profoundly applied in all kinds of industries, contributing a wide range of industrial applications.
 
In sum, in the machine tool industry, all kinds of machine tools would be designed and installed with at least a tool holder, or tool holders. Turning machine, milling machine, machine center, drilling machine, boring machine, and even tapping machine are all designed with tool holders and can clamp and un-clamp tools so that the worn out cutters can be replaced by the new one or be re-shaped again for future machining tasks, and in the machine tool sector, a machine taper is a system for securing cutting tools or tool holders in the spindle of a machine tool or powered tools.

Furthermore, almost all machine tool spindles, and many powered tool spindles, are designed with a taper as their primary method of attachment for tools. Even on many conventional and advanced drill presses, handheld drills, and turning machines, even they have chucks, the chuck is still attached by a taper as well. Meanwhile, on the drills, drill presses, and milling machines, the male member is the tool shank or tool holder shank, while the female socket is integral with the spindle. This integration design is adopted long in the industry and onsite operators inherit this custom to operate during their machining operations.
