To start to get the answer of the production technology of Gester taber abrasion tester, first, let’s understand the core structural production craft of GT-C14A taber abrasion tester. This section will cover the most comprehensive aspects of how to manufacture the key functional structures of the taber abrasion tester, which is the foundation of the stable performance of the equipment.
In layman’s terms, the core production of GT-C14A taber abrasion tester is centered on the precise matching of the specimen turntable and abrasive wheel, and the accurate control of speed and load. All structural manufacturing is based on the principle of simulating the actual wear of materials, to ensure the authenticity and repeatability of test data.
But extensively, the production technology of GT-C14A taber type abrasion tester involves metal precision processing, electronic control system assembly, weight forging and calibration, and accessory customization. Every link is manufactured in strict accordance with the technical requirements of material wear testing, to ensure the equipment can meet the test needs of different flat materials.
a.) Wear Test Core Structure Forming Craft
The core wear test structure is the most critical part of GT-C14A taber type abrasion tester’s production, and its forming craft directly determines the test accuracy of the equipment.
Gester adopts integrated CNC machining technology for the production of the specimen turntable—the turntable base is made of high-strength aluminum alloy, and after precision turning and milling, it undergoes surface hardening treatment to avoid wear of the turntable itself affecting the test results. The abrasive wheel mounting arm is made of cold-rolled steel with high toughness, and the welding process uses laser spot welding to ensure the arm has no deformation and stable stress during rotation.
The unique wear process of GT-C14A taber type abrasion tester is realized by the precise positioning of the two abrasive wheels on the turntable. In production, the coaxiality of the abrasive wheel shaft and the turntable shaft is controlled within 0.01mm through three-coordinate measuring instrument detection, to ensure the two abrasive wheels press evenly on the test sample and form uniform wear marks during the turntable rotation.
b.) Precision Turntable Speed Control System Manufacturing
The speed control system is the "power core" of GT-C14A taber type abrasion tester, and its manufacturing craft focuses on the stability and adjustability of speed.
Gester uses a DC brushless servo motor for the turntable drive, and the motor is matched with a precision planetary reducer in production. The gear grinding precision of the reducer reaches Grade 6, which effectively reduces the speed fluctuation caused by mechanical transmission. The speed control circuit is assembled with imported precision potentiometers and PLC controllers, and through programmed debugging, the two standard speeds of 60 rpm and 72 rpm are stably output, and the speed error is controlled within ±2 rpm.
In the assembly process, the motor and turntable are connected by a flexible coupling to avoid the influence of axial and radial errors on the speed, and the whole speed control system is tested for continuous operation for 1000 hours to ensure no speed deviation in long-term use.
c.) Standard Load Weight Forging & Calibration Technology
Load weight is the key to simulating different wear pressures, and Gester has developed a special forging and calibration process for the precision steel weights of GT-C14A taber rotary abrasion tester.
The weights are made of high-purity carbon structural steel, and through die forging and precision turning, the weight error is controlled within ±0.1g. The two standard weights of 250g and 750g are marked with laser engraving technology in production—the marking clearly shows the total load on each wheel, including the fixed weight of the abrading arm (250g), so that users can directly read the actual load applied to the sample.
After forging, all weights are sent to the national metrology certification laboratory for calibration, and only the products that pass the calibration and obtain the calibration certificate are put into assembly. At the same time, the weight mounting position on the abrading arm is designed with a precision positioning groove to avoid the weight sliding and causing load deviation during the test.
d.) Accessory Customization Craft for Multi-medium Wear Testing
GT-C14A taber rotary abrasion tester has the advantage of testing with different wear medium and accessories, and this characteristic is realized by Gester’s standardized accessory customization craft.
In the production of wear accessories, Gester classifies the accessories according to the tested material properties: abrasive wheels with different grits (60#, 120#, 240#) for non-metallic materials such as textiles and plastics; diamond abrasive wheels for hard materials such as glass and metal coatings; and rubber grinding heads for flexible materials such as leather and automobile interior decoration. All accessories are manufactured with interchangeable structural design, and the mounting interface adopts a unified precision thread, which ensures the quick replacement of accessories and the coaxiality after installation.
The wear medium fixing frame is made of engineering plastic with high corrosion resistance, and the injection molding precision is controlled within 0.02mm to ensure the medium is stably fixed and does not fall off during the turntable rotation.
The production technology of Gester GT-C14A taber abrasion testing equipment is formed on the basis of more than ten years of experience in material testing equipment manufacturing, and its core advantages are concentrated in four aspects, which are also the core competitiveness that distinguishes it from ordinary taber abrasion testers in the market.
-
Integrated structural manufacturing for stable wear test
The core wear structure adopts one-piece CNC machining and laser welding technology, without splicing gaps and structural deformation. The precise positioning of the abrasive wheel and turntable ensures the uniformity of the sample wear, and the test data deviation is less than 1%, which is far higher than the industry average.
-
Dual-speed precision control with low fluctuation
The DC brushless servo motor and Grade 6 planetary reducer are matched with PLC programmed control, which realizes the stable output of 60 rpm and 72 rpm. The speed does not deviate under long-term continuous operation, and it can adapt to the long-time wear test of various materials.
-
Calibrated precision steel weights with clear marking
The high-purity steel weights are forged and calibrated by national metrology institutions, with ultra-small weight error. The laser engraving marking includes the abrading arm weight, which avoids the user’s calculation error and ensures the accuracy of the applied load.
-
Standardized accessory customization for multi-medium testing
The accessories are customized according to the material characteristics, with unified interchangeable interface design. The quick replacement of accessories can meet the wear test of more than 30 kinds of flat products such as suitcases, carpet, glass, and metal coatings, and the accessory compatibility is strong.
The production of GT-C14A taber abrasion testing equipment is fully oriented to international material wear testing standards, and all manufacturing processes are designed and controlled according to the requirements of the standards. The equipment has passed the compliance certification of multiple international standards, including:
ASTM D3884, ASTM D1175, ASTM D1044, ASTM D4060, ASTM D4685,
