Transfer machining systems that are designed to perform various operations on the same part, such as drilling, milling, turning, threading, boring and more. They have a special clamping system. The workpiece is transferred from one machining station to the next. This system allows the simultaneous machining of several pieces each clamped in their own position, one next to the other, on a turntable.
In this way, there is no other production time that is added as on a sequential machining system. The advantages of such a system are high productivity (for an annual production of millions of parts), high accuracy (positioning the table by indexing ± 0.0025 mm) and high flexibility (rapid machine conversion).
Alternative or complementary technologies
Powder metallurgy is a technology that makes it possible to manufacture a structural product by compressing metal powder in a matrix followed by hot densification called sintering, hence the name sintered parts. The two main reasons for choosing a sintered part instead of a forged, forged or molded part are that the sintered parts are made from an efficient and inexpensive technique.
Advantages
Machining Lathe Perth offers, among other advantages, the reduction or elimination of machining and raw material losses, good surface finishes, and self-lubricating properties as well as a reduction in manufacturing and assembly costs. It is a reliable method that can produce, at a relatively low cost, parts of various metals and alloys, simple or complex shapes and often final dimensions.
Thixomolding is an innovative semi-solid-state molding process that involves casting an alloy under pressure at a temperature at which the solid and liquid phases coexist. This technique, the principle of which has been known for more than 20 years, has been developing rapidly over the past few years and has now reached the stage of recognized industrial process for certain large-scale parts made of aluminum alloy or magnesium alloy.
Machining Lathe Perth allows you to directly create parts with dimensions, without subsequent machining or with a limited machining restart. The dimensional accuracy is substantially identical to that of die casting.
Typical defects in molded parts, such as porosity are virtually eliminated resulting in higher mechanical properties for the same alloy than in die casting. The wear of the molds is more limited than in traditional molding (order of 250 000 injections against 150 000 in die casting).
The alloys, which have been studied and applied in thixomolding, are mainly foundry aluminum and magnesium. The produced parts mainly concern the automobile (fuel injection ramps, hydraulic suspension cylinders, hydraulic distributors and engine mounts), aerospace, structural nodes (bicycle frames) as well as electronic components and components.
