Precision processing technology cultivated in VCRs

　Household VCRs, which gather the best of the Japanese art of “KARAKURI” – traditional automation mechanism – have made the technology of Japan known to the world and laid the foundation for Japanese manufacturing. And during its heyday, more than 70 million VCRs were made annually worldwide.

TENKING had been making the head drum – the heart of recording and playback – since its birth. For that purpose, machining accuracy was required to manage the accuracy of hundreds of thousands of parts mass-produced each month on the order of microns. It was an amazing machining accuracy at that time.

In order to maintain that level of accuracy, the temperature in the entire factory floor was tightly controlled to minimize variations in product dimensions caused by environmental changes. This allowed us to overcome the conflicting requirements of mass production and high-precision.

This idea has been handed down to TENKING (THAILAND). We have been controlling the temperature of the entire precision processing site since our company’s establishment in 1996, and we are still mass-producing micron-order products.
