How does a CNC glass cutting machine improve accuracy?

A CNC glass cutting machine enhances accuracy by using computer numerical control technology to guide the cutting head with high precision. This allows for exact dimensions, reduced errors, and the ability to cut both straight and complex shapes. Compared with manual methods, CNC cutting minimizes waste and increases speed. At LIJIANG Glass, our CNC glass cutting machines are designed with advanced software and durable structures, ensuring consistent performance for industrial glass production. See product .

Can I polish glass with a glass polishing machine?

Yes, a glass polishing machine is designed to smooth and refine glass edges after cutting, creating a clear and safe finish. These machines are commonly used for architectural glass, mirrors, furniture glass, and decorative applications. With multiple grinding and polishing heads, they deliver uniform results and reduce manual labor. At LIJIANG Glass, we supply reliable glass grinding and polishing machines that ensure efficiency and high-quality edge finishes for your production needs. View details .

How to Choose the Right CNC Glass Cutting Machine for Your Workshop

When investing in a CNC glass cutting machine, it’s important to select equipment that matches your workshop’s production needs. First, consider the cutting accuracy and speed. CNC machines use computer numerical control to ensure precise cuts for both straight and shaped glass.

Next, evaluate the machine’s software compatibility, automation features, and table size to match the dimensions of your typical glass sheets. A high-quality CNC cutting machine should reduce waste, improve efficiency, and require minimal downtime.

For workshops aiming to scale production, automation features such as auto-loading and break-out functions are essential. You can explore more about our glass machinery solutions to find the right fit.

At LIJIANG Glass, we provide advanced CNC glass cutting machines designed to maximize productivity and accuracy, ensuring long-term performance for industrial use.

Glass Machine Maintenance Guide: Keep Your Equipment in Top Shape

A well-maintained glass machine is the foundation of efficient glass processing. Regular maintenance not only extends the lifespan of your equipment but also ensures consistent quality output. Start by performing daily cleaning to remove glass dust and debris, which can affect precision and safety.

Next, schedule periodic checks of mechanical components, such as cutting heads, polishing wheels, and conveyor systems. Proper lubrication of moving parts will reduce wear and tear. It’s also essential to update control software for CNC glass machines to maintain accuracy.

If you operate equipment such as a glass polishing machine or a CNC glass cutting machine, follow the manufacturer’s guidelines for inspections and part replacements.

At LIJIANG Glass, we not only provide reliable glass machinery but also long-term service support to keep your workshop running smoothly with minimal downtime.

Glass Tempering Furnace vs Other Glass Processing Machines – Which Do You Need?

Choosing between a glass tempering furnace and other processing machines depends on your production goals. A glass tempering furnace is designed to heat glass to a high temperature and then cool it rapidly, increasing strength and safety. This makes tempered glass ideal for architectural, automotive, and safety applications.

On the other hand, machines like CNC glass cutting machines or glass polishing machines are essential for shaping and finishing glass before tempering.

For businesses aiming to enter large-scale safety glass production, investing in a high-quality glass tempering furnace is the right choice.

At LIJIANG Glass, we provide complete glass machinery solutions to help manufacturers choose the right equipment for their specific needs.

Insulating glass: the best choice for building energy saving and comfort

Insulating glass was invented by Americans in 1865. It is a new type of building material that is good at heat insulation, sound insulation, beautiful and practical, and can reduce the weight of buildings. It is made of two (or three) pieces of glass, using a high-strength and high-airtightness composite adhesive to bond the glass sheets to an aluminum alloy frame containing a desiccant to make high-efficiency sound insulation and heat insulation glass. Common insulating glass is 5+9A+5 double-layer insulating glass. Here, 5 refers to the thickness of the glass, which is 5mm, 9 refers to the hollow part of 9mm, and the letter A is the abbreviation of air. There are also models on the market such as 5+15A+5, 5+22A+5, 5+27A+5, 5+32A+5, etc.
PART01
Basic structure of insulating glass
01
Original glass
You can use colorless transparent glass of various thicknesses and sizes, as well as tempered, laminated, wired, embossed, colored, coated, non-reflective glass, etc.
02
Spacer
A structural product made of aluminum or aluminum alloy to form a cavity, used to fill molecular sieves, isolate hollow glass sheets, and play a supporting role. The spacer has the function of holding molecular sieves; protecting adhesives from sunlight and extending their service life.
03
Molecular sieve
Its function is to balance the humidity between the glass. When the humidity between the glass is too high, it absorbs moisture, and when the humidity is too low, it releases moisture to balance the humidity between the glass to prevent the glass from fogging.
04
Inner sealant
Butyl rubber has stable chemical properties, outstanding air tightness and water tightness, and its main function is to prevent external gas from entering the hollow glass.
05
Outer sealant
The outer sealant mainly plays a fixing role because it will not flow due to its own weight. The outer sealant belongs to the structural adhesive category, with great bonding strength and good sealing. It forms a double seal with the inner sealant to ensure the air tightness of the hollow glass.
06
Filling gas
For ordinary air and inert gas, the initial gas content of insulating glass should be ≥85% (V/V). Insulating glass filled with argon slows down the heat convection in the insulating glass, thereby reducing the thermal conductivity of the gas, and performs well in sound insulation, heat preservation, energy saving and other aspects.
PART02
Main performance characteristics of insulating glass
01
Sound insulation and heat insulation
Since the desiccant in the aluminum frame keeps the air in the glass hollow dry for a long time through the gap on the aluminum frame, the insulating glass has excellent heat insulation performance; it can reduce the noise by 27-40 decibels, and the 80 decibel noise outside is only 50 decibels indoors.
02
Good light transmittance
This allows the light in the clean room to be easily transmitted to the visiting corridor outside. It also better introduces outdoor natural light into the room, improves the brightness of the room, and creates a more comfortable production environment.
03
Improved wind pressure resistance
The wind pressure resistance of insulating glass is 15 times that of single-piece glass.
04
High chemical stability
Generally speaking, it has strong resistance to acids, bases, salts and chemical reagents. In this regard, it is easy to become the first choice for clean room construction in many pharmaceutical companies.
05
Good transparency
It allows us to easily see the conditions and personnel operations in the clean room, which is convenient for observation and supervision.
