Are you interested in cutting and drilling copper? Supplier Evek GmbH offers to buy copper at an affordable price in a wide range. We will ensure the delivery of products to any point of the continent. The price is optimal.
Separating operations with copper billets are carried out mainly on sheet, high-quality and combined scissors, since the intensive adherence of copper chips to the metal-cutting tool prevents the obtaining of high-quality billets. Cutting of rolled copper is carried out on crank shears with inclined knives. In the case of cutting a thick sheet or copper plates, sheet shears with a hydraulic drive are advantageous, which ensure the gradual introduction of the knives into the cut metal. The quality of the cut increases with the reduction of technological gaps between the moving and stationary knives.
Cutting of bars and a circle
For cutting copper rods and a circle, high-shear press-shears are used. Closed and semi-closed segments are used, since the resulting compression stresses contribute to obtaining a quality cut. In the absence of proper technological equipment, the cut preforms are subjected to preliminary sedimentation. In cases when automated stamping of copper products (for example, on cold-cutting machines) is conducted, only semi-closed knives are used at the cutting position. Supplier Evek GmbH offers to buy copper of domestic and foreign production at an affordable price in a wide range. We will ensure the delivery of products to any point of the continent. The price is optimal.
Drilling of copper
The processes of producing blind or through holes on copper billets using metal cutting equipment are complex, because of the high ductility of the material, intermittent chips are formed. It becomes the main cause of jamming and breaking drills. Therefore, drilling of copper is recommended to be carried out at large feeds, when continuous, waste chips are formed.
Before deep drilling (or for making holes with a diameter of less than 2 mm), the preforms are pre-hardened by mechanical means — surface cold forging. The surface of the metal becomes harder, and the chips are more free-flowing. The drilled copper is drilled at smaller, than usual, sizes of feeds, and sharply sharpened drills.
