Introduction
Skiving technology is an art that can be traced
back to the early 20th century, a time when the
whole process of skiving was done manually and
where the machine consisted of only a rotating
blade and a stationary knife bed with the sole intent
of belting and handling other leather vessels.
The leather industry hadn’t experienced any
other invention as impactful as the skiving machine
when it was first developed by the hands of Julius
Wilhelm in the Pitler household.
Industries like the leather goods, automotive, and
furniture industries have over time continued to
develop the art of using the skiving machine to
create smooth surfaces for the finishing edges of
various materials.
This guide gives a piece of detailed knowledge
about the definition, diagrammatic description, uses
and benefits, maintenance, and safety precautions
of the skiving machine.
A skiving (scarfing) machine is a specialized
equipment designed to thin materials such as
leather or furniture to achieve a desired thickness
and create tapered edges. It utilizes a cutting
mechanism to remove layers from the material’s
surface, resulting in smooth and even thickness
throughout.
The level of precision the skiving machine offers
in terms of smoothening the surface of various
materials to achieve the desired thickness and make
tampered edges on materials.
This image
shows the skiving machine in the smoothening
process of a leather piece.
Break-Down Of The Skiving Process
Skiving is a delicate art that involves the skiving
machine being set up correctly and in good working
condition, including checking the blade sharpness,
adjusting the cutting depth, and ensuring proper
alignment of the material feed before the whole
skiving process begins.
Thereafter choose the appropriate material for
skiving based on the specific requirements of your
project, always ensure that the material is clean,
free from any defects, and properly sized for the
skiving machine to give a flawless result.
Adjusting the settings of the skiving machine
according to the thickness and type of material
being skived follows up after the appropriate
material has been picked, which includes adjusting
the feed speed, and blade pressure to achieve the
desired skiving results.
Following up the material to be skived on the
feeding table of the skiving machine is properly
positioned, ensuring that it is properly aligned and
secured in place to avoid errors.
The main skiving process is then initiated by
turning on the skiving machine, the material will be
fed through the machine, and the skiving blade will
remove a thin layer of material from the edge,
creating a tapered or thin profile.
After a while, the skiving machine is closely
monitored to ensure that the material is being
skived evenly, and necessary adjustments to the
machine settings or material positioning can be
made to correct any issues that may arise.
Once the skiving process is complete, carefully
inspect the skived material for any defects or
inconsistencies. It is very vital to check the thickness
and taper of the skived edge to ensure that it meets
the desired specifications as it is one of the most
crucial details involved in skiving.
Depending on the requirements of your project,
you may need to perform additional finishing
touches on the skived material, such as trimming
any excess material or smoothing the skived edge
with sandpaper or a burnishing tool for the final
result.
A Full Diagram Of The Skiving Machine
This diagram shows how the skiving machine looks
in a complete display
The drawing below displays a breakdown of the
internal look of the components of the skiving
machine.
The skiving machine is a sophisticated machine
that comprises parts that make the skiving process
possible.
These components are well explained below:
1.Feed Roller: The feed roller is a major component
of the skiving machine that assists in guiding the
material through the machine, ensuring a
consistent feed rate.
This is a diagram of
the feed roller component in the skiving
machine compartment, it is partially hidden
from the external view of the skiving machine.
- Presser Foot: The component of the skiving
machine responsible for the function of holding
the material in place during the skiving process,
preventing slippage, and determining the width
and angle of skiving done is known as the presser
foot.
3.Cutting Blade: The cutting blade is the primary
component responsible for thinning the material.
It can be adjusted to achieve different thickness
levels required for the project at hand.
