He was accompanied by Pak Thae Song, Hwang Pyong So, Hong Yong Chil and Yun Tong Hyon.

He looked round the room dedicated to the education in the revolutionary history.

Watching with great attention precious historic relics and data there, he looked back with deep emotion on the shining course covered by the factory.

Looking round various places of the factory including the processing shop, heat treatment shop and assembling shop, he learnt in detail about the modernization of equipment and production.

At the processing shop he acquainted himself with the use of the old equipment.

He expressed great satisfaction over the fact that the workers and technicians of the factory remarkably improved the performance of the equipment by positively introducing latest technology including digital display into updating the existing equipment, true to the instructions given by leader Kim Jong Il during his field guidance to the factory.

Noting that the factory set high goals and achieved a lot of successes by stepping up the modernization of equipment in recent years, he said he was pleased that the factory updated old equipment with less cost, in particular.

He underscored the need for other units to conduct a dynamic campaign to make an effective use of the existing equipment as the factory did when updating equipment.

Learning about the technical specifications and economic efficiency of the CNC-based metal-working machine produced by the factory by its own efforts and with indigenous technology, he said it is good for the factory to manufacture efficient machines and use them in production. He also learned about the operation of the CNC-based machines newly installed at the factory.

Making a round of the heat treatment shop, he praised the workers of the factory for having modernized the heat treatment process through a campaign for technical innovations and thereby improving the quality of material heat treatment while cutting down its cost.

At the assembling shop he saw a newly built modern machine and highly praised once again the workers of the factory for their successes in production and scientific and technological achievements.

Noting that many machines and equipment are now required by various fields, he underlined the need to operate the factory in full capacity by taking thorough measures for the supply of materials.

If the factory is to carry out its plan without fail, it is necessary for it to scrupulously organize production, step up the work to put the production processes on a modern and scientific basis and steadily improve the technical skills of its workers, he added.

Then he visited various places of the factory including a canteen, daily provision store and bean processing ground to pay deep attention to the living of its workers.

Expressing expectation that the employees of the factory would make a contribution to the development of the country's machine-building industry by registering bigger successes in production, he had a photo session with them.
