五金沖壓件加工包括沖裁、彎曲、拉深、成形、精整等工序。沖壓件加工的材料主要是熱軋或冷軋（以冷軋為主）的金屬板帶材料，例如碳鋼板、合金鋼板、彈簧鋼板、鍍鋅板、鍍錫板、不銹鋼板、銅及銅合金板、鋁及鋁合金板等。

stamping process includes blanking, bending, drawing, forming, finishing and other processes. The main materials for stamping parts are hot rolling or cold rolling (cold rolling), such as carbon steel, alloy steel plate, spring steel plate, galvanized plate, tin plate, stainless steel plate, copper and copper alloy plate, aluminum and aluminum alloy plate.

五金沖壓件材料的硬度檢測，其主要目的就是確定購入的金屬板材退火程度是否適于隨后將要進行的沖壓件加工，不同種類的沖壓件加工工藝，需要不同硬度級別的板材。

stamping material hardness testing, the main is to determine whether the purchase of metal sheet annealing is suitable for subsequent stamping parts processing, different types of stamping processing technology, the need for different hardness levels of the plate.

薄板：鋸削時盡可能從寬面鋸下去，若必須從窄面鋸下時，可用兩塊木墊夾持，連木塊一起鋸下，也可把薄板直接夾在虎鉗上，用手鋸作橫向斜推鋸，使鋸齒與薄板料接觸的齒數(shù)增加，避免鋸齒崩裂。

Thin plate: sawing as far as  as wide as when sawing. If must be sawed from narrow surface, it can be held by two wooden blocks and sawed together with wooden blocks. The sheet can be clipped directly to the vise, and a hand saw is used as a transverse oblique saw to increase the number of teeth contacted with the sheet material and avoid the crack of the saw teeth.

深縫：鋸削深縫時即當鋸縫的深度超過鋸弓高度時，高度時，鋸弓就會與工具相碰，無法繼續(xù)鋸削；此時應將鋸條拆出，將鋸條轉90。

Deep seam: when sawing deep seams, when the depth of the sawblade exceeds the height of the saw bow, when the height is high, the saw bow is touched by the tool and can not continue to be sawed; the saw strip should be removed and the saw blade is turned 90.
