Taiwan Nakazawa provides a full range of TNC precision metallographic cutting machines, which are used for metallographic analysis, hardness testing and other related testing requirements for metal sample sampling in metallographic pretreatment. It has a fully automatic intelligent cutting system and perfect personal protection. System, use LED lighting system to provide bright operation space, exclusive body structure design, provide stable and comfortable metallographic cutting experience. It is widely used in metallurgical pretreatment applications in the metal product industry, teaching institutions, and scientific research units, and is compatible with the cutting of different metal materials.
TN Precision Abrasive Cutting Machine comes with 3 different types according to user preference and suitability:
Large Automatic Precision Abrasive Cutting Machine
– TNC-255ASL
– TNC-305ASL
– TNC-355ASL
– TNC-355ASL-FA
Small Automatic Precision Abrasive Cutting Machine
– TNC-200AS
– TNC-230AS
– TNC-255AS
Small Manual Precision Abrasive Cutting Machine
– TNC-200MS
– TNC-230MS
– TNC-255MS
The cutting room is the main area for the daily work of the operator. The new TNC re-plans the space size and lighting source according to the user’s height and operating habits. The bright working environment can improve the efficiency and comfort of the user, so that cutting is no longer one. A boring and messy job.
The new fast positioning fixture combines high flexibility and high clamping force, which improves the safety performance for the clamping of complex products. The stepless slide rail design meets the requirements of different size products without repeated disassembly and installation of different fixtures. Maximum opening size: 210mm
Spindle and motor are the most core parts of the cutting machine. The high efficient spindle is durable design for demanding environments. TNC cutter has the excellent performance even under high-intensity work and toughest condition.
With EASY FEED function, the sensor will detect at the end of the cycle and automatically retracting the sample to the starting point after each operation. In the meanwhile, the buzzer alarm signalling the completion of section process.
SMART CUT (optional) – Setting the upper limitation of amerage, the cutting will automaticall stop and retreat until finishing the cutting. This intelligent feeding system has significant reduce the percentage of the disc fragment during the cutting process especially for the large workpieces.
It is a special screw afterburner fixture suitable for small products. It is cut and processed from a single piece of steel. It is strong and durable. After heat treatment, it is the best choice in terms of mechanical properties and corrosion resistance.
In the automatic feed mode, the equipment will automatically sense the set end point of the feed. After cutting, the stage will automatically return to cutting under the condition of ensuring the cooling function. Cut the origin, and buzzer prompts that the cutting is complete.
The integrated LED anti-splash panel provides a wealth of function settings: adjustment of the feed speed And display, function setting of intelligent feed, etc.
The feed hand wheel can be switched to automatic feed in one second, and the automatic feed starts by pressing the panel Key to start the automatic feed mode.
