Within the SQS Precision CNC Machining and Measurement Department, we comprehensively deal with the entire production and inspection process focusing on shape-complicated parts that meet high requirements for precision, quality of workmanship and defined roughness of machined surfaces.
Machining Technology Preparation, CNC Programming
Using the latest version of CAM software makes it possible to efficiently perform: production feasibility assessment, production technology optimization, production process simulation, CNC programs preparation.
CNC Machining
SQS workshop’s modern machine equipment has been chosen in view of covering a wide range of requirements for prototype development and production of high-precision mechanical parts.
Machined materials: brass, copper, ARCAP, aluminum alloys, stainless steel, titanium, Kovar, Inconel, Invar and other difficult to machine materials.

Measurements
In the field of mechanical parts measurement, the department is equipped with top instruments from the world's leading manufacturers. The base consists of contact measurement of dimensions, geometric tolerances, profile and roughness. Due to the nature of the production, it is also necessary for the department to be equipped with a contactless measurement of micro-machining products.
Coordinate Measuring Machine
- » Size of measuring space X / Y / Z: 300 / 200 / 200 mm

A separate off-line station is used to prepare measurement plans, simulate measurement procedures and optimize them outside the coordinate measuring machine.
3D Optical Measurement Machine
Detailed inspections of surface profile and structure – the department uses a 3D optical measuring machine equipped with several lenses and software for composing and processing the measured data, including the possibility of automatic measurement and evaluation. The machine is also equipped with a motorized rotary axis unit for easy acquisition of complete 3D data.
