In precision manufacturing, micro-hole machining is one of the most challenging processes. With diameters typically below 1 mm, these holes demand extremely tight tolerances, roundness, coaxiality, and surface integrity. Micro-holes are widely used in medical implants, fuel injector nozzles, high-pressure fluid control valves, and micro-sensors. The small size leaves no room for error, requiring engineers to balance tool selection, machine stability, thermal deformation, and inspection methods to achieve consistent quality.
In precision metal manufacturing, threads may seem simple, but they directly affect assembly reliability and component performance. Improper machining of internal or external threads can result in dimensional deviations, thread deformation, or burrs, compromising sealing effectiveness and assembly efficiency. In high-precision applications such as medical devices, automotive parts, and aerospace components, even minor thread defects can pose significant risks. Therefore, mastering proper thread machining techniques and inspection strategies is critical.
In precision machining, surface roughness affects not only part appearance but also product longevity, friction behavior, and assembly fit. When design requirements reach Ra 0.2 μm or finer, standard cutting alone is insufficient. Achieving stable results requires process control combined with post-machining finishing techniques.
Thin-wall components are widely used in aerospace, medical devices, and precision machinery. However, machining thin-wall parts presents unique challenges. Due to extremely thin walls, any deviation in cutting force, thermal effect, or fixture clamping can induce dimensional errors or permanent deformation, directly impacting assembly precision and service life.
5-axis machining provides exceptional flexibility for producing complex geometries, enabling efficient machining of multi-angle features, inclined planes, and freeform surfaces. However, the true challenge does not lie in the machine itself, but in planning and optimizing the toolpath. Poorly designed toolpaths can lower machining efficiency, accelerate tool wear, degrade surface quality, and significantly increase the risk of collisions or part scrap.
In precision component manufacturing, locating holes are critical elements that determine overall assembly accuracy. They not only affect reference positioning between parts but also influence geometric accuracy and functional reliability. Although machining locating holes may seem straightforward, multiple detailed factors must be considered. Neglecting them can result in noticeable deviations during later assembly or inspection stages.
In high-precision machining, controlling only the dimensions within specified tolerances may still result in poor fits, wobbling, or unwanted noise. These issues often stem from neglecting concentricity, rather than simple dimensional errors.
In the field of precision machining, it is common to receive engineering drawings that include only basic dimensions without clearly defining tolerances, machining methods, or critical geometric requirements. Although such drawings may appear “complete,” they often lead to misunderstandings, delays, and even unusable parts during manufacturing.
In precision manufacturing, dimensional accuracy directly impacts the performance and lifespan of components. Jig grinding is a specialized machining method designed for high-precision holes, geometric tolerances, and reference surfaces, making it particularly suitable as a final finishing step after CNC or EDM. With jig grinding, engineers can achieve precision levels unattainable by other machining methods.
