If the CNC machines aren't too old, almost any 3-axis CNC machine can be upgraded to a fully functional 4- or 5-axis machine. However, certain controllers limit simultaneous operation (e.g., only 4 axes simultaneously, 5th axis only positioned). Every upgrade must be carefully clarified and sometimes requires the constructive collaboration of the machine supplier or manufacturer.
Advantages
The CNC machine is being massively upgraded and partially automated. pL LEHMANN has a clear advantage here: A variety of parameter lists and specific commissioning instructions are offered, with competent support from specialists from Switzerland on all well-known CNC controls such as Siemens, Heidenhain, Fanuc, Mitsubishi and Brother Haas.
Disadvantages
Without high levels of expertise from the turntable or machine supplier, professional retrofitting is hardly possible. The latest machinery directives make it even more difficult.
Frequently Asked Questions
Can't I do the retrofit myself?
Answer: This is entirely possible for a trained service technician from a machine manufacturer or dealer. For an end customer, however, it is a very difficult undertaking and usually doomed to failure. It requires a network of specialists (manufacturers of machines, CNC, measuring systems, etc.) along with special knowledge in parameterisation and PLC adaptation.
What is the main advantage of an upgrade?
Answer: This depends on the starting point. If the machine is already in operation, it can be semi-automated with relatively little effort, significantly increasing the machine's autonomous operating time and noticeably reducing unit costs.
