In the global tube mill industry, a flying saw is far more than a cutting machine.
It is a critical part of the production line.
When a steel tube is continuously moving at high speed, the saw must accelerate, synchronize with the tube, complete the cutting process, retract, and return to its original position—all within a very short cycle.
At the same time, the system must maintain cutting length accuracy, cut quality, mechanical stability, production speed, blade life, and reliable operation over thousands of production hours.
This is where true flying saw technology makes a difference.
For more than 30 years, Shenyang CONTOR Electromechanical Equipment Co., Ltd. has focused on one thing:
From hot saw electrical control systems in the early 1990s, to cold flying saws, milling flying saws, and today's laser flying saw technology, CONTOR has continuously developed its technology through real production applications around the world.
Today, CONTOR has become one of the world's leading specialists in flying saw technology, with approximately 110 employees dedicated to flying saw and related tube mill equipment, annual production of around 300 machines, and customers across more than 50 countries.
Our philosophy is simple:
European-level performance. Chinese engineering efficiency.
CONTOR has its roots in Shenyang, China, one of the country's most important traditional industrial cities.
The company was founded by several professors from Shenyang Ligong University, bringing an engineering and academic background into industrial equipment development from the very beginning.
In 1992, CONTOR began its business with electrical control systems for hot saws used in tube mill production lines.
At that time, the mechanical structure of the hot saw was manufactured by other Chinese tube mill equipment manufacturers. CONTOR worked closely with these partners, focusing on the electrical control and automation side of the equipment.
This early experience became extremely important.
Because the company was involved directly in tube mill production lines from the beginning, CONTOR gradually developed a deep understanding of the relationship between:
Tube Mill + Mechanical System + Electrical Control + Cutting Process + Production Requirements.
This foundation would later become the basis for CONTOR's development of flying saw technology.
In 2008, CONTOR introduced its cold flying saw technology to the Chinese market.
The beginning was not easy.
Like any new technology, the early generation of cold flying saws had many challenges.
The technology was new to the Chinese tube mill market.
The machines were relatively expensive.
And customers needed to gain confidence in a new cutting technology before adopting it on their production lines.
But Chinese tube manufacturers gave CONTOR something extremely valuable:
Chinese customers supported the development of domestic cold flying saw technology and were willing to use the equipment in real production environments.
Every production line became a test platform.
Every problem became an engineering lesson.
Every improvement was incorporated into the next generation of equipment.
Over many years of continuous application and improvement, CONTOR cold flying saws became increasingly stable and reliable.
This is an important part of CONTOR's history.
We did not develop flying saw technology only in a laboratory.
We developed it on real production lines, together with real tube manufacturers.
As CONTOR cold flying saw technology became increasingly mature, another advantage began to emerge.
Chinese manufacturing efficiency.
By that time, China's manufacturing industry had developed a highly competitive supply chain for mechanical components, electrical systems, machining, automation, and industrial equipment.
This allowed CONTOR to offer advanced flying saw technology at a highly competitive international price.
The combination was powerful:
Mature technology + solid manufacturing + competitive cost + fast engineering response.
As international tube manufacturers began to recognize the quality and value of Chinese flying saw technology, CONTOR rapidly expanded into overseas markets.
Today, CONTOR has supplied equipment to customers in more than 50 countries.
According to CONTOR's long-term sales and installation data, our cold flying saws have reached a leading global sales position, making CONTOR one of the most widely used brands in this specialized field.
This global market experience has also created an important advantage:
CONTOR equipment has been tested by different materials, different tube sizes, different production speeds, and different manufacturing environments around the world.
The real challenge of a flying saw is not simply cutting a tube.
The challenge is cutting the tube while the tube is continuously moving at high speed.
A typical cutting cycle requires the flying saw to:
Accelerate → Synchronize → Cut → Retract → Return → Repeat
Thousands of times during continuous production.
At high production speeds, even a small synchronization error can affect cutting length accuracy.
Insufficient mechanical rigidity can affect cut quality.
Incorrect cutting parameters can reduce blade life.
Poor motion control can limit the speed of the entire tube mill.
Therefore, a high-performance flying saw is a highly integrated system combining:
Mechanical engineering
Servo motion control
Electrical control
Cutting technology
Tube mill process knowledge
Automation
Real-world production experience
This is precisely where CONTOR has built its expertise.
One of CONTOR's most important competitive advantages is not visible from the outside.
It is the motion control system.
The motion controller is the "brain" of a flying saw.
It determines how the machine:
accelerates,
synchronizes with the moving tube,
controls cutting motion,
manages acceleration and deceleration,
coordinates multiple axes,
returns to the cutting position,
and communicates with the entire tube mill.
CONTOR has developed its own motion control technology and continuously upgrades it according to changing market requirements and real production experience.
This is a long-term engineering capability.
Instead of relying entirely on standard third-party control solutions, CONTOR continuously develops and optimizes its motion control system around the specific requirements of flying saw applications.
The result is one of the characteristics customers value most:
A flying saw may have impressive specifications on paper.
But for a tube manufacturer, what really matters is whether the machine can run reliably every day, every shift, year after year.
That is the standard CONTOR continues to pursue.
CONTOR's technology has continued to evolve with the market.
After establishing its cold flying saw technology, CONTOR developed profile milling flying saws, providing another solution for high-quality tube cutting applications.
Today, CONTOR has also developed laser flying saw technology, opening a new chapter in high-speed, high-precision tube cutting.
Laser flying saws combine:
Laser cutting technology + high-speed motion control + tube mill synchronization + automated process control.
This is not simply a laser mounted on a moving machine.
It requires precise coordination between the laser system, motion control, production line speed, cutting parameters, and material characteristics.
CONTOR's laser flying saw has already entered commercial applications and, according to CONTOR's sales and installation data, has achieved a leading global sales position in this emerging product category.
This gives CONTOR two complementary technology platforms:
For proven, high-volume, high-speed tube production.
For next-generation high-precision and highly automated tube cutting applications.
Technology ultimately has to be proven in the factory.
CONTOR's equipment is currently used by customers across the automotive, steel, tube manufacturing, and renewable energy industries.
Our customer base includes internationally recognized companies such as:
Gestamp/voestalpine/Lingyun/BYD
as well as major Indian industrial customers including:TATA/Apollo/PMEA
These customers operate in demanding industrial environments where equipment reliability, production efficiency, precision, and long-term serviceability are critical.
For CONTOR, these customers represent more than sales.
They represent decades of accumulated engineering experience.
Every international project helps us understand another material, another tube specification, another production speed, another factory environment, and another customer's expectations.
This accumulated experience continuously feeds back into our product development.
Automotive tube and structural components remain an important application area for CONTOR.
But the development of new energy industries is creating new opportunities.
CONTOR flying saw technology has entered the solar photovoltaic mounting structure industry, where steel tubes and structural profiles are produced at high speed and in large volumes.
Solar mounting systems require:
High production efficiency
Continuous operation
Accurate length control
Reliable automation
Low operating cost
Stable performance
These requirements are highly compatible with CONTOR's flying saw technology.
The expansion from automotive and traditional tube manufacturing into photovoltaic structures demonstrates the flexibility of CONTOR's core technology.
The application areas may change.
The fundamental technology remains the same:
High-speed, precise, reliable online cutting.
This is an important point.
CONTOR does not compete by being the cheapest flying saw supplier in China.
In fact, CONTOR's flying saws are positioned at the premium end of the Chinese market.
Why?
Because our customers do not simply buy a machine.
They buy:
Reliability.
Engineering experience.
Stable motion control.
Consistent cutting performance.
Long-term serviceability.
Fast technical response.
In international markets, CONTOR's pricing is competitive with many Turkish flying saw suppliers.
But customers frequently tell us that the difference becomes clear after the machine starts running:
The equipment is more solidly built, the operation is more stable, and the machine is easier to use.
This is exactly the market position CONTOR wants to maintain.
We do not want to be the lowest-priced supplier.
We want to offer the best balance between:
This is more than a slogan.
It describes the competitive philosophy that has driven CONTOR's international development.
European and Japanese equipment manufacturers have accumulated decades of experience in industrial automation and tube mill technology.
CONTOR respects this engineering heritage.
At the same time, China's manufacturing ecosystem provides unique advantages in:
Engineering response
Manufacturing efficiency
Supply chain integration
Customization
Cost control
Delivery speed
CONTOR combines these strengths.
Our goal is not to imitate European or Japanese manufacturers.
Our goal is to develop our own engineering capabilities and provide global customers with equipment that meets demanding industrial requirements while maintaining the efficiency and flexibility of Chinese manufacturing.
That is what we mean by:
Today, approximately 110 professionals work at CONTOR, with the majority focused on flying saw technology and related tube mill equipment.
Our annual production is around 300 machines.
As customer requirements have evolved, our capabilities have also expanded beyond the flying saw itself.
CONTOR now also provides automatic tube bundling, stacking, and packing systems for the downstream section of tube production lines.
This allows us to support customers not only at the cutting stage, but also with selected downstream automation solutions.
Nevertheless, our core remains unchanged:
When customers choose a flying saw, they are not simply choosing between machines.
They are choosing between engineering philosophies.
Some suppliers compete primarily on price.
Others compete on brand history.
CONTOR competes on a combination of:
Decades of experience in tube mill electrical control and flying saw technology.
A dedicated focus on cold flying saws, milling flying saws, and laser flying saws.
Continuous development and optimization of our own motion control systems.
Equipment operating in more than 50 countries and regions.
Experience serving demanding automotive and metal-processing customers.
High engineering value without the cost structure of traditional European equipment.
Flexible customization, efficient manufacturing, and rapid technical support.
The global tube industry is changing.
Higher-strength steels are becoming more common.
Production speeds continue to increase.
Automation is becoming standard.
Solar and new energy applications are growing.
Laser technology is developing rapidly.
And manufacturers are increasingly focused on total production cost rather than simply equipment purchase price.
These changes create new opportunities for flying saw technology.
CONTOR will continue investing in:
Cold Flying Saw Technology
Milling Flying Saw Technology
Laser Flying Saw Technology
Motion Control
Production Line Automation
Downstream Tube Handling and Packaging
and Digital Process Optimization.
Our ambition is not to become the manufacturer with the largest number of different machines.
Our ambition is more focused:
More than 30 years ago, CONTOR started in Shenyang, a traditional industrial city in China.
We began with electrical control technology for tube mill hot saws.
We entered the cold flying saw market in 2008.
We learned through thousands of real production applications.
We improved through every customer project.
We developed our own motion control technology.
We expanded from China into the global market.
We developed milling flying saws.
We developed laser flying saws.
We entered the automotive industry.
We entered the solar photovoltaic industry.
And today, CONTOR equipment is running in factories around the world.
Our story is still being written.
But one thing has never changed:
We are committed to one technology.
Making tube cutting faster, more precise, more stable, and more efficient.
