*CNC cutting
*How to keep safety
1, understand all the operation manual: before using the equipment, to
fully understand and master the relevant instruction manual. When new
equipment is introduced, the operating manual of the equipment needs
to be studied and understood in detail.
2, keep the equipment clean: not only the machine tool itself, but
also the working environment, should be kept tidy. Chips and debris
should be cleaned up in a timely manner to avoid interfering with the
operation of the machine or causing safety accidents.
3、Regular fine inspection: for example, check whether the oil rubbing
plate on the machine tool guideway is worn out, whether the lubricant
and coolant status is normal, if there is any problem, it should be
replaced or supplemented in time.
4, equipment protection: for rotating cutting tools, belts and
pulleys, high-voltage circuits, noise and compressed air and other
safety hazards brought about by the preventive protection measures
should be taken.

Reason for selection
1.Dimensional adaptability: CNC milling machines (machining centers)
usually have a large workspace and flexible machining capabilities,
which can adapt to the machining needs of gears of different sizes.
Since you mentioned "not very large gears", the machining
range of CNC milling machines should be sufficient to meet your
needs.
2.High precision: CNC milling machines use advanced CNC technology
to achieve high-precision machining. Modern CNC machining accuracy
can reach the micrometer level, which is crucial for the tooth
profile accuracy and fitting accuracy of gears.
3.Material adaptability: CNC milling machines can process materials
of various hardness, including metals, plastics, etc. You need to
choose the appropriate cutting tool and machining parameters based
on the material of the gear.
4.Processing efficiency: CNC milling machines have an automatic tool
changing function (if equipped with a tool library), which can
greatly improve processing efficiency. By writing appropriate
machining programs, multiple machining steps of gears can be
completed at once, reducing machining time and cost.
Key points for selecting CNC milling machines
1.Machine specifications: Ensure that the selected CNC milling
machine's workbench size and spindle power can meet the
machining requirements of the gears.
2.CNC system: Choose a stable and reliable CNC system to ensure
machining accuracy and stability.

*Make sure the material
In the video, a complex threaded part was processed using stainless
steel, which is the most common metal raw material.
Material Definition
Stainless steel is an alloy steel mainly composed of iron (Fe) and at
least 10.5% chromium (Cr), and may contain other elements such as
nickel (Ni), molybdenum (Mo), titanium (Ti), and copper (Cu). Chromium
is the most important alloying element in stainless steel, as it can
form a dense layer of chromium oxide (Cr ₂ O æ) film on the surface of
the steel, which can prevent further oxidation and corrosion of the
steel, giving stainless steel excellent corrosion resistance.
The reason for choosing stainless steel as the raw material
-
Corrosion resistance: Stainless steel has excellent corrosion
resistance and can maintain constant corrosion resistance in air
or corrosive media.
-
High strength and toughness: Stainless steel exhibits high
strength and toughness over a wide temperature range, enabling it
to withstand various stresses and impacts.
-
Processing characteristics: Although stainless steel may encounter
some problems during the processing, such as severe work
hardening, high cutting force, high cutting temperature, and easy
tool wear, it can adapt to higher cutting speeds and optimize the
processing by selecting appropriate tools, processing parameters,
and surface treatment methods.
-
Environmental protection and recyclability: The 100% recyclability
of stainless steel provides a new way for environmental
protection, which meets the requirements of modern manufacturing
for sustainable development.
*Laser cutting
Laser cutting is the use of focused high power density laser beam
irradiation workpiece, so that the irradiated material rapidly
melting, vaporization, ablation, or to reach the ignition point, and
at the same time, with the help of coaxial with the beam of
high-speed airflow blowing off the molten material, so as to achieve
the workpiece cut. Laser cutting belongs to one of the thermal
cutting methods.
*How to keep safety
Overall environmental protection
Environmental settings: When using laser cutting machine,
corners and baffles should be set up in the cutting area to
avoid the laser's rebound from
harming the human body.
Installation of protective facilities: the use of laser must
be equipped with professional protective equipment, such as
ultraviolet, laser and electromagnetic radiation protection
devices.
Maintain the equipment: Regularly check and maintain the laser
cutting machine to ensure that the equipment can operate
normally and reduce the occurrence of accidents.
Personal protection
Wear protective eyewear:
the operator must wear qualified laser protective eyewear,
which can effectively prevent the laser beam from harming the
eyes.
Wear protective gloves:
During operation, protective gloves should be worn to avoid
injury to the hands from laser radiation.
Wear suitable protective clothing: suitable protective
clothing is required to prevent laser burns or burns to the
skin.
Machine operation
Caution: When using the laser cutting machine, it must be operated
cautiously to avoid harm caused by accidental misoperation.
Cutting area protection: For the cutting area, it should be
operated in strict accordance with the operation procedure to
prevent the laser from irradiating the irrelevant area.
Standardized operation process: In the operation process, the
laser cutting machine must be operated in accordance with the
standardized process, and the operation process or operation
parameters must not be changed at will.
