Metalworking

Die or lerka is a tool for cutting external threads on parts. Varieties dies there are many, will tell you about the ones that are most often used at home and at work.

When working with metal, always need his treatment and cut, this is designed with special cutting machines. These machines are used both at home and in large enterprises and factories.

In this article we will focus on the German vertical milling machining centers. What characteristics are some models of popular brands. And we will understand how good these machining centers.

the Basic plumbing tools are: files, vises, wrenches, scribers, wrenches, chisels, screwdrivers, hammers, table anvil, pliers, grinding machines.

I Can say that it is better to buy a separate and a thickness planer. For example, thickness planer Dewalt with a cast iron bed. The transfer of torque he is using a pair of V-belts, there is a function of self-sharpening of the paintings of the jointer, saws, and cutters.

According to the existing classification tools, all used cutting tools can be divided into three technological groups: the tail, shaft-mounted and flat, or prismatic.

complex Parts require processing, in which the instrument should describe a trajectory in the three Cartesian coordinates in combination with the inclination of the tool and rotating workpiece (i.e. the two circular axes). You can use a couple of rotary axes A + B or B + C for different 5-axis machines, a General scheme ….  Read More

Under deployment give 0.05-0.1 mm in diameter. Sharpened drill on a modern machine gives 0.05-0.10 increase in the diameter of the hole. And with coolant it is necessary to deploy. The essence of the deployment is uniform removal of stock from the bore for highest accuracy and surface finish of the hole.

currently, the manufacture of dies and molds increasing and currently almost formed. A detailed examination of the operations in the production of press dies, get that 75% is the machining.

Question machinability of high-temperature steel quite successfully resolved, high-temperature Nickel-based alloys, while maintaining their physical and mechanical properties at high temperature and having low thermal conductivity and thermal diffusivity, are ill-equipped to handle their cutting.< / span>   Developing high contact temperature on the surfaces of the cutting tool with a high specific pressure contributes ….  Read More
