When it comes to threading or grooving you certainly have a wide variety of possibilities from which to choose. As you may already be aware, each different kind of threading tap is intended to serve a distinct function in a variety of different contexts. Others are more suited for hard materials, while some are better for softer materials. It is extremely essential to be knowledgeable about the many various kinds of threading tools that are accessible to you since this will enable you to choose the most appropriate one for the threading jobs that you want to do.
What are Threading and Grooving Machines?
When it comes to threading, there are
several solutions available. As you may already be aware, each threading tap is
built for a certain function and application. Some are better for harder
materials, while others are better for softer ones. Understanding the many
kinds of threading tools available is crucial, as it will help you to choose
the appropriate one for the job at hand.
Grooving or recessing operations, also
known as necking operations, are often performed on the shoulders of workpieces
to guarantee proper fit between mating components. When a thread must run the
whole length of the item to a shoulder, a groove is often cut to enable the nut
to move freely. Prior to cylindrical grinding, grooving the workpiece enables
the grinding wheel to fully grind the workpiece without hitting the shoulder.
Different Types of Threading Machines
Hand Taps
Hand taps are a typical sort of threading
tool that can be purchased at practically all local hardware stores. Despite
its prevalence, it is not suitable for CNC operations. It is stated that hand
taps are one of the most cost-effective threading instruments since they can
provide excellent results with low expense.
Plug Taps
Plug taps have between three and five
threads. Bottoming taps often have fewer threads than taper taps. Depending on
where you are, the bottoming tap may also be referred to as the plug tap.
Power Taps
Power taps are a kind of powered tap that
resembles a "spiral point" plug tap. It is often referred to as the
"gun tap." This style of tap features cutting blades that are angled
relative to the tap's midline. This design allows the chip to be constantly
broken and expelled into the hole, eliminating congestion.
Creating Taps
Forming type differs significantly from
other kinds of taps. Unlike cutting taps, which remove metal from the sidewalls
of the hole, forming taps force-displace metal into a threaded shape after
being inserted into the hole. Because forming taps may only be used on pliable
materials such as aluminum or mild steel, formed threads are often more durable
than cut threads.
Pipe Taps
Pipe taps are used only for pipe threading.
Typically, both tapered and straight pipe taps are available. Straight pipe
taps are used when the pipe thread should be straight, whereas tapered pipe
taps are utilized when the pipe thread should be tapered.
Different Types of Grooving Machines
Face Grooving
Face-grooving procedures use axial rather
than radial tool feed toward the end surface of the workpiece. The blade is
bent in order to conform to the radial curvature of the groove, which the tool
must conform to. When the machine spindle spins counterclockwise, a right-hand
version of the tool is used, and when the machine spindle revolves clockwise, a
left-hand version is used.
Both the outside and inner diameters of the
groove must be considered so that both the insert and to tool holder fit into
the groove. The diameter measured to the outside of the blade defines the
minimum diameter that can be machined, while the diameter measured to the
interior of the blade defines the maximum diameter that may be machined.
Internal Grooving
The most significant issue with internal
grooving is chip evacuation. Particularly when cutting tiny diameters, there is
a very significant chance of chip jamming, which may lead to tool failure. The
chips must first be extracted from the groove, then reverse direction by ninety
degrees and pass the tool holder’s side before being extracted from the hole.
Implementing intermittent feed into the program is the most effective method
for producing short chips. Above is displayed an internal grooving holder with
an insert.
