Trust Technology: Tongtai turning machínes, Multi-spíndle drilling and tapping machines

Tongtai is a company that has been established for over 40 years, and its quality is appreciated by customers worldwide. It was awarded as one of the top 100 Taiwan Brands in 2011. Tongtai always embraces the business concepts of exploring innovation, creating value, and pursuing customer satisfaction. The company contributes to providing the best machining experience for its customers and focuses on obtaining the latest technologies to extend its competence in the global machine tools industry.

In technology development, Tongtai seeks technology resources from Japan and Europe. It cooperates with Italian companies to develop horizontal boring and milling machines and moving column gantry milling machines. For high-speed cutting horizontal machining centers, Tongtai cooperates with German companies to develop twin spindle horizontal machine centers. The company introduced the manufacturing skills of hydrostatic systems and boring quills in the domain of horizontal boring and milling machines. In the domain of moving column gantry milling machines, it introduced the electronic compensation system of anti-backlash, 5-axis milling heads, universal milling heads, and large bed gear transmission systems. Due to cooperation with European companies, Tongtai has kept in step with high-end technology.

In machining the key components of Tongtai machines, the company uses 30 different types of in-house machining equipment, including 5-dimension machining centers, vertical milling machines, horizontal boring and milling machines, horizontal machining centers, vertical machining centers, and CNC lathes. The department of quality management performs comprehensive tests after the parts are finished. The testing instruments in the quality management department, like coordinate measuring machines and roundness measuring equipment, are used to test the components made in the factory. According to the blueprint design and all the way through production, each part is checked to ensure the precision standard is met.

To achieve the serious requests of key parts, all units of the mechanism are assembled in the constant temperature room. The important units like spindles, gearboxes, and power turrets are built by professional assembly engineers. When finished, test running and dynamic balance testing are performed. All ball bearings go through a preinstalled supersonic cleaning through the cavitations process during which extra high pressure is produced. This effect removes any and all attached dirt molecules. The temperature control module of spindle run-in can spread lubrication grease evenly on the ball bearings and the rail gaps and assure good spindle performance and extend product life.

All machines are assembled by experienced engineers. Every engineer engages appropriate adjustments during the process. In addition, Tongtai organizes senior engineers from within the factory and outside experts in the industry to hold in-house technology seminars frequently for improving the technology level of its employees and to maintain advanced and reliable assembly skills. With a professional attitude and careful step-by-step machine assembly, Tongtai assures that the machines it produces will remain in a stable precision situation.

For assuring assembly precision, Tongtai not only sets internal controls through Standard Operating Procedures, but also has designed self-check forms for each machine assembly line. Employees can follow the forms to enforce setting and testing tasks to check the quality of products anytime. Moreover, the quality control department has more than 30 professional testing engineers to make sure the results of precision testing are correct. With a series of SOP training, testing personnel can provide professional and accurate tests for each machine according to the recorded data in the forms. Tongtai's testing engineers enforce the tests with over 25 different testing instruments.
