BTA drilling is a type of professional deep hole drilling mechanism which utilizes a special drilling tool on a long drilling tube for the production of deep holes. BTA drilling can be conducted on metal, from holes with a diameter of 20 millimeters and even larger, and can go up to the depth to diameter ratios of four hundred: one. For te deep hold drilling practice, BTA drilling is one of the most effective methods, because this method renders a cleaner, more reliable and feasible process compared to the conventional twist drills method. It can achieve larger diameters and higher feed rates than the alternative gun drilling method.
BTA deep hole drilling machines are the specifically designed models that can deal with BTA drilling request. BTA drilling machines can do many deep hole drilling processes with ease compared with traditional drilling machinery. In the metal working industry, within the drilling sector, the equipment deep hole drilling machine is one of the highly studied and evolved machine tool models that can deal with multiple types of deep hold making and boring-related tasks all at one stop due to its multitasking and convenient design. At the very first, drilling machines were evolved from the design of milling machines at the early 20th century, and after that, a diversified of machine centers are broadly applied in all kinds of industries for professional and precision usages, contributing a broad range of industrial achievements.
BTA deep hole and radial drilling are both specific purposes in the drilling phase, and here the radial drilling is to be introduced first. This idea can be used to describe a wide variety of computer programmed based controlled drilling machine that drills and sometimes plus bores, and the machineries that include several critical accessories designed and assembled together with the machine frame itself, such as tool magazine, ATC, power tool turret, multi-axis working tables with some different guide movement designs. Regarding the drilling machine inventory, besides the model of vertical and horizontal arrangement, there are still other categories in the machining center inventory, and the most common one is of course the conventional drilling machines.
Gun drilling is another way to conduct deep hole drilling. For this idea to be illustrated, we have to know better about the conventional drilling machine first. Drilling machine is one of the highly studied and evolved machine tool models that can deal with multiple types of hole making and boring-related tasks all at one working station due to its multitasking and convenient designs in the modern industry especially in the metal working field. Further, drilling machines were in fact evolved from the design of milling machines at the early 20th century, and after that, a diversified of machine centers with drilling functionality are broadly applied in all kinds of industries for professional and precision usages, contributing a broad range of hole making efforts.
Gun barrels are an obvious component for deep hole making process. In the metal drilling, the term gun drilling is conducted by gun drills which are straight fluted drills that permit cutting fluid to be injected through the drill's hollow body to the cutting face. BTD drilling machines can deal with different kinds of deep hole tasks, and the barrel issue is the same with the gun drills. Gun drills are adopted for deep drilling, which is a depth to diameter ratio of about 300:1 or more.
Other usages of the gun barrels include mold production, die manufacturing, and the manufacture of combustion engine parts such as crankcase, and wood wind musical instruments, because gun drills can drill long straight holes with steady pace in various materials such as metal, wood, and even some plastic materials that are often hard to be drilled with good results. In regard to the cooling mechanism of deep hole drilling, the coolant itself can provide lubrication and cooling to the cutting edges. It can remove the chips from the drilling hole. Today, modern gun drills use carbide tips to prolong lifespan of the tools and to reduce total cost when they are compared with steel tips.
Like all the contact based cutting procedure, gun drill tools would eventually be worn out due to the continual usages of the tooling systems. In the industry, tool grinding is a common in-plant operation for metal working sector, and there are a whopping of industries that require such process in order to make the whole working process more smooth during the machining procedure. For drill grinding, the situation is the same. In the metal drilling, the term gun drilling is conducted by gun drills which are straight fluted drills that permit cutting fluid to be injected through the drill's hollow body to the cutting surface.
