Small Manual Metallographic Cutting Machine -TNC-MS Series
Product Description

MIT Made in Taiwan


100% designed by a Taiwanese engineering team in collaboration with top industrial suppliers and experts in professional metal manufacturing and metallography academia, creating metallographic cutting machines suitable for the metal and technology industries. Widely used in research institutions, the automotive industry, aerospace, metal manufacturing production, heat treatment processing, and more.

Applicable to related fields including: metal hardness characterization, heat treatment process evaluation, carburized hardened layer thickness, induction hardening, welding area hardness, cemented carbide analysis, electronic component observation, as well as technical development and quality management pre-treatment processes.


Robust Steel Structure


The TNC series cutting machines are built with a high-rigidity steel structure at their core, ensuring stability and durability during operation while delivering outstanding cutting precision and high repeatability, allowing every sample cut to achieve consistent results.


Large fully automatic metallographic cutting machine TNC-ASL series, 100% designed and manufactured in Taiwan, suitable for the metal and technology industries.

Large fully automatic metallographic cutting machine with a bright and user-friendly operating space, improving user efficiency and comfort, making cutting no longer a tedious and messy task.

Bright and User-Friendly Operating Space


The cutting chamber is the primary workspace for daily operation. The new TNC model has been redesigned based on users' height and operating habits, including optimized spatial dimensions and lighting sources. The spacious and bright working environment improves user efficiency and comfort, making cutting no longer a tedious and messy task.


Flattened Work Area

The complex and precision mechanism’s smooth linear guide is cleverly hidden beneath the cover plate, creating a flat working surface. This design not only enhances overall aesthetics but also effectively reduces hard-to-clean corners, making maintenance easier and more convenient.





Manual/Auto Quick Switching


Equipped with a patented switching mechanism that significantly simplifies the operation process, allowing users to quickly switch between manual and automatic modes. This enhances operational flexibility and makes it easier to handle different processing requirements with ease.

Comprehensive Fixture Ecosystem


A wide range of fixture options is available, allowing flexible configuration according to sample size, shape, and processing requirements, creating the most suitable clamping solution.




Quick Fixture System


Suitable for small samples or applications requiring frequent changeovers, featuring a quick-locking function that significantly reduces operation time. The TN quick fixture system provides a clamping force of over 200 kg, meeting most application requirements.





Screw-Type Fixture


Designed with square-thread screws to provide strong and stable clamping force, suitable for high-pressure fixing applications and ensuring stable, non-deviating cutting processes.







 



Cutting Core – Precision Cutting Spindle


This machine adopts a precision spindle equivalent to that used in machining centers, delivering excellent concentricity and tight tolerance control. The power transmission uses a multi-groove belt design, which maintains stable rotational speed even under high-load and high-tension cutting conditions, ensuring cutting quality and efficiency.


Large Quick Infinite Linear-Slide Fixture (TNC-355ASL)


The new quick-positioning fixture combines high flexibility with strong clamping force, improving safety when holding complex workpieces. The infinite linear-slide design accommodates various product sizes without the need to repeatedly disassemble and install different fixtures. Maximum opening size: 210 mm.

Large quick infinite linear-slide fixture (TNC-355ASL), combining high flexibility and strong clamping force, improving safety for complex workpiece clamping.
 
 
Small High-Strength Screw Booster Fixture (TNC200/230/255)


A screw-type booster fixture designed specifically for small workpieces. It is machined from a solid block of steel, making it robust and durable. After heat treatment, it offers excellent mechanical performance and superior corrosion resistance.

Intelligent Feed Function (Optional)

Based on different material characteristics, this function performs human-like reciprocating feed control by correlating current variation with cutting load. It effectively handles high-hardness material cutting requirements, improving processing stability while extending the service life of the cutting wheel and further reducing overall consumable costs.
 

Magnetic Filtration Device (Optional)


Reduces the frequency of manual cleaning of the circulating water tank. It also minimizes coolant deterioration caused by residue, extends service life, makes residue collection easier, reduces costs, and lowers the risk of cooling system clogging.



Laser Tool Setting System (Optional)


Equipped with a laser tool setting system that significantly simplifies the traditional tool setting process, reducing manual adjustment time and error sources. It improves operational efficiency and positioning accuracy, making operation more intuitive and faster.

 
 
Simple and Reliable Control Interface


The control interface is designed with simplicity and intuitiveness in mind, integrating and optimizing complex parameters through a single-chip control system for precise cutting. The feed speed is digitally set, providing clear and accurate operational references, making every adjustment more precise and controllable.



Reinforced Glass Observation Window


The chamber observation window is made of high-strength tempered glass, offering excellent durability and safety. It allows clear monitoring of the cutting process, improving operational judgment efficiency while extending overall service life.
 
 
Full Machine CE Certification


Ensuring user safety is our top priority. Whether in electrical safety or daily cutting operations, the machine is designed in compliance with international CE safety standards to safeguard users.

Automation Functions


In automatic feed mode, the machine automatically detects the preset feed endpoint. After cutting is completed and while ensuring the cooling function is active, the stage automatically returns to the cutting origin, accompanied by a buzzer alert indicating completion.

The integrated waterproof LED panel provides comprehensive function settings, including feed speed adjustment and display, as well as intelligent feed configuration.

The feed handwheel can be switched to automatic feed in one second. Press the automatic feed start button on the panel to activate automatic feed mode.

 


High-Efficiency Cooling System


Depending on different processing requirements and usage scenarios, water tanks with suitable capacities can be flexibly selected to achieve optimal cooling performance. A magnetic filtration device is also available as an option to effectively remove cutting debris, maintain coolant cleanliness, extend equipment and consumable lifespan, and ensure long-term stable operation.






Consumable Compatibility


The TNC cutting machine is compatible with consumables from major international brands. It offers high compatibility, allowing users to freely select suitable metallographic consumables based on different cutting requirements and tasks. For consumable specifications, please contact our service team.


Easy Maintenance


The TNC series cutting machines encapsulate the feed system within a stainless steel protective structure, significantly reducing maintenance requirements. Only periodic lubrication of the feed screw is needed. Users may also contact TN service to purchase scheduled maintenance services, where professional technicians will perform system maintenance.
