Drilling & tapping is one of the oldest machining or cutting techniques in use today.
What is drilling & tapping?
Drilling is a cutting process that uses a drill bit to cut a hole of circular cross-section in solid materials. The drill bit is usually a rotary cutting tool, often multi-point. The bit is pressed against the work-piece and rotated at rates from hundreds to thousands of revolutions per minute. This forces the cutting edge against the work-piece, cutting off chips (swarf) from the hole as it is drilled.
In manufactured parts, holes with female screw threads are often needed; they accept male screws to facilitate the building and fastening of a finished assembly. One of the most common ways to produce such threaded holes is to drill a hole of appropriate size with a drill bit and then tap it with a tap.
Factors That Make DOBEMY Drilling Superior to Conventional Drilling.
Dobemy machine is a precision machining technique that is used frequently in the mechanical industry. Some industries like sport fitness equipment and furniture parts manufacturing demand tighter and faster drilling. In such cases, the DOBEMY drilling takes precedence. It certainly has overtaken the application of conventional hole drilling for the following discussed reasons.
Effective for drilling curved surfaces.
When it comes to curved surface drilling, the conventional drilling method often fails. The reason for this is that curved surfaces are subjected to internal stress and strain, which resists the motion of a conventional drill. In the case of DOBEMY Machining, there is The 360-degree rotating axis controls the round tube/pipe for efficient and high-precision drilling, which allows precise drilling on the curved surfaces.
Suitable for thick wall material drilling and thread.
Conventional Drilling and tapping becomes difficult on thin wall material surfaces. Often thin walled particles of the material interrupt the tool which makes the drilling and tapping even more difficult. Unlike conventional drilling, DOBEMY drilling has the potential to pass through the thin wall material. This thermal friction drilling is suited for thin wall.
Reduces chip formation and interruption for drilling and tapping.
Materials have a tendency to burr or chip during conventional drilling, due to metal to surface direct contact. This affects the speed and precision of the drilling and tapping process. However, in Dobemy Machining, Thermal friction drilling reduces chip formation and increases the speed of the operation.
Enhanced surface finish.
Conventional drilling is a function of friction between the tool and the surface, therefore it causes an uneven surface finish. Deburring is performed for recovering the surface finish but it is time-consuming and may affect the drill dimensions. Dobemy drilling and tapping does not create burrs, therefore it gives a smooth surface finish.
Although Dobemy drilling offers several benefits over the conventional drilling, the choice of the right technique will depend on your application requirements. If you intended to get professional drilling and tapping machine done, it is always better to approach an expert like DOBEMY, which is a leading CNC machine supplier in China. The company has been offering these services to sport fitness equipment, furniture, medical equipment, automotive and tool manufacturing industries.
