The manufactured machine is a linear multi spindle lathe for the production of lead-free brass components demanded by the valve market in order to comply with increasingly stringent international health and environmental regulations. Today, we will cover and analyse this machine, its features and uses. The features of this linear multi spindle lathe are perfectly suited to processing lead-free brass components, which are generally much more difficult to machine with cutting tools than leaded materials, (whether brass or and steel).
One of the issues facing the manufacturing world is the handling and use of lead-free materials. New European regulations are in fact moving in this direction, which the United States and Canada had already taken in the early 1980s. Companies producing items such as taps, fittings and connectors - or more generally products that come into contact with water for human consumption, for example - will be obliged to use lead-free materials.
We resume our analysis of single-spindle, multi-spindle and CNC machines working with bar. It is well known (see article link) that machining from bar is the most common production system, but this also has its problems, which we will analyse after looking at vibration problems, inertia instability and the various effects on the machine.
In the world of bar turning, the most common production system is machining from bar. Why? Because it is the most logical. It is no coincidence that practically all single and multi-spindle machines use it: it is by far the most common system for most turned parts. This is a fact.
The problem of long chips is a challenge, and difficult to solve completely. What can be done is to manage chips in a slightly different way, for example, using special ergonomic arrangements of vertical spindles to help with chip extraction.
Set-up time is at the heart of Linea Spindle’s design, with a set-up time of only 15 minutes! But let’s start at the beginning. What is set-up time? Set-up time is the time that elapses from finishing the last unit of a production series to starting the first of another. One of the aspects you need to address if you want to remain flexible in responding to market demands is precisely the rigidity of production processed characterized by high tooling and production change times.
