Technical support for Mazak machines: on-site electronic and mechanical repairs
Mazak machine tools are found in numerous workshops and production departments and, particularly in the case of machines that have been in operation for several years, may require electronic and mechanical repairs to resolve faults, malfunctions or issues related to component wear.
However, a machine stoppage does not always allow the root cause of the problem to be identified immediately.
A fault may affect the control system, a drive or an electronic component, but it may also be due to mechanical elements, the tool changer, the pallet changer system or the machine’s geometric conditions.
For this reason, the ability to carry out an analysis directly at the customer’s premises allows us to assess the machine’s actual behaviour and identify the necessary intervention.
Assistec provides on-site electronic and mechanical support services, including for Mazak machines fitted with Mazatrol 640 and Mitsubishi M64 control systems, drawing on the expertise it has developed in servicing multi-brand CNC machine tools.

PLC logic for machine safety is one of the areas that may require attention when an existing machine tool has outdated or inadequate safety functions, or when these functions are no longer suitable for the machine’s current configuration.
However, improving machine safety is not simply a matter of modifying a few lines of PLC code. The process must begin with a risk assessment, followed by identifying the required safety functions, checking the devices already installed and determining how they should interact with the PLC, drives, sensors, interlocks and machine components.
On CNC machine tools, changes to PLC logic may be required, for example, to correctly manage automatic doors, permissive signals, stopping functions, protective devices or newly integrated automation systems.
For this reason, modifying PLC logic should be considered part of a broader machine safety and functional verification process, rather than an isolated software task.

The CNC spindle is one of the most important elements of a machine tool: it is the component that transmits motion to the tool and, together with the machine’s other systems, determines precision, machining quality and production reliability.
When a spindle begins to show signs of wear, the problem is not limited to the component itself. Abnormal vibrations, loss of precision or increased noise levels can, in fact, compromise the entire production process, leading to scrap, premature tool wear and unscheduled machine downtime.
For this reason, the overhaul of CNC spindles should not be regarded as a simple repair job, but as a technical operation aimed at restoring the spindle to its original operating condition and ensuring stability and precision once again.
Relying on a professional service allows the real causes of the problem to be identified, worn components to be replaced and more serious faults that could halt production to be prevented.
