Producing a precision component does not only mean machining it correctly. It means verifying that each part meets the required specifications every day, on every order, regardless of volume.
In MI.SO. the quality control is not a final step, but a integrated system that accompanies the entire production: 130 daily checks, high-precision instrumentation and a structured process according to ISO 9001:2015 certification.
Because quality control is part of production, not an add-on
In precision turning, a dimensional error of a few hundredths of a millimetre can render a component unusable. Discovering it at the end of production means scrap, delays and additional costs. Discovering it during production means take immediate action, before the problem multiplies.
That is why at MI.SO. control does not start when production ends: it starts with production, and accompanies it until the last piece.
The quality control process at MI.SO.
Our control system is divided into precise stages, each with specific instrumentation and objectives.
1. First Before an order enters full production, the first part produced is fully checked. Every dimension, tolerance and finish is compared with the specifications in the technical drawing. Only after this validation does production proceed.
This step is crucial: it identifies any deviations in the machine setup before they result in hundreds of non-conforming parts.
2. During production, parts are sampled and checked at regular intervals. This makes it possible to monitor process stability and intercept dimensional drifts in real time, before they become a quality problem.
The 130 daily checks we perform at MI.SO. mainly include this phase: a continuous verification which guarantees consistency from the beginning to the end of each batch.
3. At the end of production, each order undergoes a final inspection. The customer receives a certificate of conformity with full traceability to ISO 9001:2015, which documents the measurements taken and confirms compliance with the required specifications.
The instrumentation: precision for every need
Quality control is only as effective as the tools with which it is performed. At MI.SO. we have a full equipment, chosen to cover different types of verification.
Keyence IM-8020
Optical measuring system with spindle. It combines speed and accuracy optimally for series inspection: it allows the measurement of dozens of dimensions in seconds, making the volume of 130 daily inspections sustainable without slowing down production.
Zeiss O-Inspect 322
Co-ordinate measuring machine with optical and probing system. It offers high accuracy and a wide measuring range, and is the tool of choice for in-depth sampling, first-piece validation and verification of complex geometries. Zeiss is the industry standard for applications requiring the highest dimensional reliability.
Supporting instrumentation
To complete the system, we use specific tools for targeted checks:
- Profile projector: for quick profile and geometry checks
- Hardness tester: for checking surface hardness after heat treatment
- Rugosimeterfor measuring surface finish
- Comparator: for quick and comparative checks
- Micrometersfor the dimensional verification of incoming materials
- Calipers: used directly in production by operators
- Calibrated pads (internal and external): for checking threads and holes in production
Automotive standards as a reference for all sectors
At MI.SO., our control system is inspired by the standards of the automotive industry, which are among the most demanding in terms of quality management in production.
This means that even those who do not produce for the automotive industry benefit from a structured, documented approach geared towards error prevention rather than mere detection.
Certification ISO 9001:2015 formalises this commitment: it defines processes, responsibilities and traceability requirements that guarantee the customer a reliable and verifiable quality system.
Concrete advantages for ordering precision components
A structured control system is not a cost: it is a warranty which translates into benefits measurable for those who have to supply precision components.
- Zero surprises during assemblyComponents arrive in conformity with specifications, without the need for further internal verification
- Full traceability: each job is documented and certified, with measured data available
- Consistency on batches of any sizethe same level of control on 100 pieces and on 10,000 pieces
- Reducing wastecontinuous checks during production intercept problems before they multiply
- Compliance for regulated sectorsautomotive, medical, food, ISO 9001:2015 documentation supports supplier qualification processes
“130 checks a day are not a number: they are the answer to the question every purchasing manager should ask his supplier, how do you ensure that every part is compliant?”
Consistent quality, batch after batch
Quality is not a random result. It is the product of a systemcalibrated tools, defined processes, trained people and a corporate culture that considers control an integral part of production and not a slowdown.
At MI.SO. this system produces 130 checks every day, on every job, for every customer. From the first piece to the last in the series.
