1, structure of machine tool shield and layout should be designed reasonable, make human body cannot enter dangerous area directly. 2, the strength with due and enough shield, steel is spent, should use metallic stuff to make commonly, below the condition that spends in contented intensity and steel, also can make with other data. 3, shield should be used as far as possible close structure, when the spot needs to use reticulate structure, safety is apart from since and the mouth width of mesh should accord with following requirement: (1) when be being harmed to prevent to finger tip is passed by accident and be caused, have mouth breadth: Diameter and edge grow or the short axis dimension of elliptic aperture should is less than 6.

5 ㎜, safe distance should not be less than 35 ㎜. (2) when be being harmed to prevent to finger is passed by accident and be caused, have mouth breadth: Diameter and edge grow or the short axis dimension of elliptic aperture should is less than 12.

5 ㎜, safe distance should not be less than 92 ㎜. (3) to prevent the palm (do not contain the first palm to point to joint) when be passed by accident and causing harm, have mouth breadth: Diameter and edge grow or the short axis dimension of elliptic aperture should be less than 20 ㎜, safe distance should not be less than 135 ㎜. (4) when be being harmed to prevent to upper limbs is passed by accident and be caused, have mouth breadth: Diameter and edge grow or the short axis dimension of elliptic aperture should be less than 47 ㎜, safe distance should not be less than 460 ㎜. (5) when be passed by accident to prevent sufficient needle and causing harm, shield bottom and ground (or stand mesa) clearance should not be less than 76 ㎜, safe distance should not be less than 150 ㎜. 4, usually, should adopt stationary shield, often have the athletic part that adjust and upholds, should preferential introduce chain type shield, when the condition does not allow, can introduce open type or adjustable type shield. 5, shield surface Ying Guang slips, without burr and sharp edge, should not become new dangerous source. 6, shield should not affect the line of sight and normal operation, answer to check and be safeguarded of facilitating equipment. 7, of shield outside the wall should besmear with yellow.
