Conventional Tool Holders and Modern Turret Technology: A Comparison

In the machine tool industry, all kinds of machine tools would be designed and installed with at least a tool holder, or tool holders.

About Tool Holders

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.

Tool holder and machine Taper

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 (i.e. with a taper) fits into the female socket, in which there is a matching taper of equal angle.

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 (such as a drill chuck or collet chuck), the chuck is still attached by a taper as well. On the other hand, 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.

Drill press

In the case of the drill press, onsite operators may want toinstall a bit directly, or using a drill chucks. Now almost all milling machines, from the oldest manual machines up to the most modern CNC (computer numerical control) or NC machines, utilize tooling that is piloted on a tapered surface. These designs have greatly improved the productivity due to the convenient nature during the processing which lead to shorter cycle time.

Turning machines

Meanwhile, in the case of the turning machine, the male part may belong to the tool or to the spindle, while the spindle noses may have male tapers, female tapers, or both parts. Onsite machine tool operators have to have the capacity to install or remove tool bits quickly and easily since the working cycle has to be shortened as fast as they could. Therefore, for instance, a turning lathe has a rotating spindle in its headstock, and to which the onsite operators may want to install a spur drive or work in a collet device.

Power transmission

Machine tapers allow for high power transmission rates across the interface devices, which are needed for milling machines if they are con-jointed. Moreover, machine tapers can be further categorized into self-holding and self-releasing sorts. Regarding the self-holding tapers, the male and female wedge together and are bind to each other for the extent that the given forces of drilling can be resisted effectively without a drawbar.

The new trend is coming or now?

In both automotive and 3C consumable electric sectors, manufacturers that need to proceed machining tasks in the 21st century tend to purchase machining centers for a wider application. Machine tools are the most fundamental capital goods for manufacturers and play the critical role that determines the final output of the end products, and the quality of the machine tool becomes the key point of the quality of the manufacturers’ final end products. The inventory of machine tools varies from time to time.

Accordingly, now after the invention of the machining centers and the programmed controlling system (CNC, computer numerical control), the standards of machining become more and more rigid compared with the standards before. Besides the CNC machining centers, there are also CNC turning centers, CNC milling machines, CNC tapping and milling centers, CNC drilling and milling centers, and other customized machinery models.

Merging functionality

Nowadays, some machine tools that do belong to the machining center family try to be versatile as well. Although they are not as versatile as machining centers, they are also very strong in machining all kinds of work pieces with complicated methodologies once if the onsite operators can add some other automatic procedures onto their production lines.

Therefore, they are usually used for specific tasks for customized projects. Therefore, the precision issue is now even stricter than ever before. Consumers from the market demand for better quality, faster speed, and shorter waiting period, so the trend becomes harsh to manufacturers. Furthermore, consumers and the consumers from the market demand for higher quality, faster speed, and shorter waiting period, so the trend becomes harsh to manufacturers now. Recently, many machine tool producers even add CMM devices into their machine tools, applying a wider field of precision standards to the machine tool sector, making their machine tools, be it machining centers, grinders, turning centers, or other model of machine tools, to be more competitive compared to the machining center counterparts.
