Asia Maintenance (hereinafter referred to as AMA) is one of the few Japanese-affiliated companies in Thailand specializing in equipment maintenance. While we handle a wide variety of machinery and repair items, this article will introduce in detail the specific repair and refurbishment services in which we particularly excel.
Rotary System Precision Unit Repair
The most frequent repairs handled by AMA involve rotary units, such as spindles. Our extensive track record is due to the high precision of our work. Bearings, which are critical for spindle repairs, require adjustments at the micron level. To achieve this precision, our factory is equipped with a precision air conditioning system that strictly maintains the room temperature at 25°C ± 1°C. All spindle repairs are conducted in this temperature-controlled environment.

After the repairs, we also conduct a test run up its specified rotational speed using a dedicated test bench to measure vibration, balance, and temperature. A report of the test run results is prepared and attached to the delivery.
▲ The temperature-controlled room houses three test benches.
Furthermore, we actively seek feedback on the quality after delivery and ensure thorough after-sales support. There are not many maintenance companies with well-equipped facilities that place such a strong emphasis on quality.
Slide (Turcite Replacement) Repairs
We perform slide regrinding, Turcite replacement, and alignment work in Thailand. We maintain a stock of various types of Turcite for slide repairs. Additionally, we are equipped with specialized tools, including dedicated adhesives and weights (four units of 1 ton each), used during Turcite replacement, ensuring our facilities are comparable to those of specialized manufacturers.

Spindle Taper Grinding
We perform grinding on the taper portion of spindles that have deteriorated in machining accuracy due to wear or damage. Typically, spindles are removed and sent to the manufacturer for re-grinding or replacement. However, AMA is equipped with specialized equipment for on-machine taper grinding, allowing us to conduct spindle repairs and taper grinding simultaneously without removing the spindle. Additionally, we can perform taper grinding on the machine table.

On-machine taper grinding is rare in Thailand, and it is not uncommon for machine tool manufacturers to request taper grinding services. As with spindle repairs, quality checks and precision measurements are conducted after taper grinding to ensure accuracy.
Equipment Overhaul/Retrofit
The ability to complete machine overhauls and renovations domestically in Thailand offers significant benefits to customers in terms of cost and delivery time. AMA has accumulated experience in overhauling machinery of various sizes, accommodating a wide range of machine types and manufacturers. We excel in providing tailored solutions, from urgent parts repairs to enhancements in equipment functionality.

In recent years, automation and labor-saving using AI have advanced in the manufacturing industry. However, mechanical engineering and maintenance remain fields where analog techniques based on the experience of technicians are crucial. While we provide business services based on our accumulated technologies and know-how, we are also dedicated to passing this expertise on to the next generation. We actively share our technology not only within the company but also with our customers involved in maintenance and management. As a Japanese-affiliated company operating in Thailand, we are committed to continuing our efforts to contribute to the development of manufacturing sites in Thailand.
