Gun Drilling Process
Explore Machines by Tooling / Process
Gun drilling process is used to produce deep and
straight holes Its generally used from holes that
are from Ø1 mm up to Ø40 mm in size with L D
ratios of up to 200 We are Gun drilling machines
manufacture
BTA Drilling Process
Explore Machines with BTA capabilities
BTA Drilling Machines Process BTA which developed
this deep hole drilling system It is the most
effective method of drilling deep holes

Ejector Drilling Process
Explore Machines with Ejector Drilling
capabilities
Ejector drilling is similar to BTA deep hole
drilling but instead of a single tube, it
consists of two tubes Precihole provides
reliable, well designed machines for this process
that are guaranteed to perform
Counter Boring Process
Explore Machines with Counter Drilling
capabilities
Counter boring Process and Operation Counter
boring enlarges an existing hole It covers a
range up to Ø500 mm hole size The number of
cutting edges on the tool varies depending on the
amount of material to be removed from the part
Once the tool enters the hole, the pads support
the finished diameter

Trepanning Process
Explore Machines with Trepanning capabilities
Trepanning is a process that removes a solid core
from the ID of a cylindrical work piece The tool
cores out a solid cross section This technology
is used for parts that use exotic and expensive
materials in which the core can be reused for a
smaller size part
Bottom Forming Process
Explore Machines with Bottom Forming capabilities
Bottom Forming Machines This process is used to
profile the bottom of a blind hole A special
profile tool is used to generate the required
profile at the end Precihole provides reliable,
well designed machines for this process that are
guaranteed to perform

Skiving Roller Burnishing Process
Explore Machines with Skiving Roller burnishing
capabilities
Skiving and Roller burnishing a high speed
process to finish hydraulic cylinder tubes
Skiving cutter shaves of a bit of the OD and the
roller burnishing pads put hydraulic pressure on
the cut surface to burnish it and improve surface
finish This process is about 40 50 times faster
than honing
Pull Reaming Process
Explore Machines with Reaming capabilities
Pull reaming machines process is used to improve
the straightness and accuracy of long holes The
reaming tool is rotated and pulled through the
drilled hole The surface finish, as well as the
size of the drilled hole, is improved using this
process

Pull Boring Process
Explore Machines with Pull Boring capabilities
Pull Boring Machines Process is being used mainly
to have very straight and accurate long holes The
oil is fed similar to BTA drilling or counter
boring ie through the pressure head Precihole
Machines are available with a variety of Toolings
based on production and application requirements
Honing Process
Explore Machines with Honing capabilities
Honing machines is a process that uses Silicon
Carbide, Aluminum Oxide, CBN or Diamond tools to
polish the ID of a cylindrical shaft Precihole
has developed both configurations i e vertical as
well as horizontal honing machines Honing process
improves the geometric form of the surface as
well as texture

Bottle Boring Process
Explore Machines with Bottle Boring capabilities
Bottle Boring Machines Process is used for
generating internal profiles in pre drilled holes
The tool expands internally when actuated while
it passes through the hole This process requires
two axis interpolation to achieve the final result
