What should I pay attention to when processing large-scale CNC milling machines?

(1) Large-scale CNC milling machine processing workshops should be first or second-class fire-resistant buildings, and other simple buildings should not be built in the workshop.

(2) For used oil rags, oil cotton yarn and oil sawdust. It should be placed in a covered metal tube (box) and processed every day.

(3) It is strictly forbidden to wipe machine tools with gasoline, alcohol, etc. in the workshop. The remaining oil after washing the parts shall not be poured into the sewer or ditch arbitrarily, but shall be poured into the container at the designated place for unified treatment.

(4) No gasoline should be stored in the workshop. The storage capacity of kerosene and kerosene should not exceed one day's consumption and should be stored in iron drums with lids. If the storage capacity is large, an oil storage room should be specially set up. No other combustibles should be stored in the oil storage room, and the indoor ventilation should be kept well. The electrical switch should be installed in the outdoor distribution box.

(5) In the workshop, due to careless use of stoves for heating, use of waste oil cotton yarn to light fires, littering of cigarette butts and matchsticks, etc., fires are often caused. Therefore, it is necessary to strictly manage on-site smoking and stove heating.

(6) If open flame welding and cutting operations are required in the workshop, the surrounding environment should be checked first, combustibles should be removed, and nearby machine tools should be covered with refractory materials. at the same time. A special person must be designated to be responsible for guardianship. After the operation is completed, the remaining fire should also be checked and eliminated.

(7) The electrical equipment for processing large-scale CNC milling machines must be inspected frequently, and hidden dangers found should be eliminated in time, and no "diseased" operation should be allowed. Installation, dismantling, maintenance, and debugging must be operated by professional electricians in accordance with regulations. The metal shells of all electrical equipment should be reliably grounded, and the grounding resistance should not be greater than 4Ω.
