COVID-19 has caused a global economic recession, and the automotive and machine tool industries have also been severely affected by this economic disaster. In addition to the decline in production demand, there is now a trend to increase automation and intelligence in production workshops to reduce labor intensity, given the lack of manpower due to isolation and the need to maintain social distancing.

  Huo Da Industrial Co., Ltd. (stock code: 1536), a leading manufacturer specializing in precision gear production and CNC gear machining equipment, has, in recent years, responded to customer demands and the trend of 'Industry 4.0' by using its Chiayi Dabu Mei Smart Factory as a practical implementation site. In this facility, it has accumulated substantial professional experience in meeting and implementing various requirements related to gear machining automation, visualization, automated measurement, quality monitoring, and record-keeping. This deep and practical experience is reflected in the design improvements and new function development of precision gear machinery, which constitutes Huo Da's unique and greatest competitive advantage in the gear machining machine market.

  Gear hobbing processing still primarily relies on manual measurement compensation. Even in general automated production, periodic inspection and compensation are required to prevent the mass production of non-conforming products that exceed acceptance standards. Hodo's intelligent production system, combined with its self-developed gear rotation measuring machine, can precisely measure the dimensions of gears processed by hobbing machines. By comparison, it can make real-time compensation for the hobbing machine to avoid producing defective products. Additionally, it judges the machine tool condition based on measured dimensions and issues warnings in a timely manner. This production system has been implemented in Hodo's Ta-Pu-Mei Intelligent Factory.

      In addition to emphasizing the large machinery department, it is noted that in recent years, industry operators have moved away from the traditional single-machine procurement model. The high precision, high efficiency, and automated production of machinery are now only basic requirements. Only those with comprehensive production technology services can meet the needs of operators. In particular, Hoda is the largest gear manufacturer in the country. Therefore, at the beginning of 2017, the department specially established an automation office, which mainly focuses on the integration and R&D of gear manufacturing automation and intelligence. It is believed that with the accumulation of practical experience in various aspects in the future, higher-level quality services can be provided.
