What is a laser cleaning machine?

A laser cleaning machine is a device that uses high-energy laser beams to irradiate the surface of materials, instantly vaporizing or peeling off pollutants such as rust, oil, coatings, and oxides attached to the surface, thereby achieving a cleaning effect.
 
The process does not require chemical reagents or mechanical contact. It is widely used in surface pretreatment and repair in metal processing, mold manufacturing, automobile maintenance, aerospace, electronics, and other industries.
 
The laser cleaning machine uses high-energy laser beams to heat contaminants to the vaporization in a very short time, instantly removing contaminants from the surface.

    FAQs

    1. What is Laser Cleaning? How Does it Work?

    Laser cleaning is a safe, environmentally friendly cleaning method. It does not require chemical agents.

    To ensure the safety of operators, it is recommended to wear goggles.

    Under specific working conditions, a small amount of smoke and dust may be generated. So it is better to equip with a smoke exhaust system to maintain a good working environment.

    The laser cleaning machine basically requires no consumables and results in low operating costs.

    Daily maintenance is also very simple, mainly including regular cleaning of protective lenses, checking the water cooling system, and cleaning the fan filter to ensure the continuous and stable operation of the equipment. If it is an air-cooled cooling system, this maintenance step can be ignored.

    The laser cleaning machine is easy to operate. HANTENCNC’s laser cleaning machine features a one-button startup and multiple preset cleaning modes, allowing even first-time users to get started quickly. 
    Additionally, we provide a complete set of operation training videos and remote technical support to ensure that our users can operate it with confidence.

    Laser cleaning is a non-contact, energy-controlled, efficient cleaning method that can accurately remove surface dirt while effectively protecting the substrate from damage.
    Due to the high power density, continuous laser cleaning can cause slight thermal effects on the surface of some materials when repeated in the same area.
    Pulse laser cleaning is more suitable for high-precision, non-destructive cleaning of sensitive materials due to its short pulse and low heat input characteristics.

    Laser cleaning machines are suitable for removing contaminants from the surfaces of various materials, including metals, stones, wood, ceramics, concrete, etc.

    It can clean rust, oxide layer, oil stains, coatings, welding slag, paint films, carbides, oxide scale, resin residues, mold deposits, etc.

    Laser cleaning is widely used in various applications, including the maintenance of manufacturing equipment, industrial parts, furniture restoration, the preservation of cultural relics, rail transit maintenance, aerospace component cleaning, military surface treatment, and the removal of paint and rust from environmental protection facilities.

    Laser cleaning speed depends on the equipment’s power, the material type, and the stain thickness.

    Generally speaking, the greater the power, the faster the cleaning speed. The cleaning speed of standard laser cleaners ranges from 1 to 5 square meters per hour.

    For light contaminants, the cleaning efficiency is higher;

    For heavy rust or thick coatings, the cleaning time is relatively long.
