At MinHe, every batch of parts follows a clear and traceable quality workflow. From incoming material verification and first-article checks to in-process inspection and final release, we document and review each step to make sure the parts you receive are consistent and reliable.
We set inspection checkpoints at incoming, first-article, in-process, and final stages. Critical dimensions, appearance, and functional features are checked against drawings and specifications, and any non-conformities are isolated and fed back into corrective actions.
Our quality lab is equipped with CMMs, optical projectors, hardness testers, and other measuring tools. Dedicated inspectors handle daily measurements and data recording, and custom gauges or inspection plans can be set up for complex or tight-tolerance parts.
We can provide FAI reports, batch inspection records, and other documentation on request. All production and inspection activities run under an ISO-based quality management system with full traceability to support your internal audits and supplier management.

This article explains how CNC machining handles sharp internal corners, covering why they are difficult to machine, the most common machining methods, and alternative solutions such as corner relief, dog-bone, and T-bone features. It is intended to help readers understand the manufacturing limits of internal corner design and the practical approaches used to optimize it.
Both 316 and 416 are common stainless steel grades, but they represent two different material selection approaches. 316 is generally preferred for corrosion resistance and demanding service environments, while 416 is more often chosen for efficient machining and improved mechanical performance. In practical projects, these two grades are commonly used for valve components, shafts, fasteners, and other industrial parts that require good surface quality and dimensional stability. This article compares 316 and 416 stainless steel in terms of machinability, corrosion resistance, heat-treating capability, weldability, magnetic properties, and typical applications to help you determine which material is better suited to your project.
In machining, a part’s edges do not always remain in an ideal condition after cutting is complete. Small metal projections often remain around hole openings, corners, and profile edges, and these are known as burrs. This article explains what burrs are, why they form, the common types of burrs, and how they can be removed and reduced.
SFM (Surface Feet per Minute) is a core parameter used to measure cutting speed and an important reference when setting machining conditions. It affects not only cutting heat and tool life, but also surface finish, chip evacuation, and overall machining efficiency. This article explains the basic concept of SFM, how it is calculated, how it differs from RPM, and the recommended ranges and common setting mistakes for different materials.
Depth of cut (DOC) directly affects material removal rate, cutting forces, and dimensional stability. This article explains how to calculate DOC in turning using a simple formula, and clarifies the mechanism difference between feed rate and DOC—feed mainly changes chip thickness, while DOC changes the chip cross-sectional area. It also outlines the key factors that govern DOC selection, including material, tool rigidity, available spindle power, and cooling/chip evacuation conditions.
Different nickel alloy families can behave very differently in machining: commercially pure nickel is more prone to adhesion and built-up edge, Monel often produces long, stringy chips, Inconel commonly shows notch wear and unstable tool life, and Hastelloy is more sensitive to heat management. This article breaks down typical problems and shop-floor symptoms by alloy family and outlines practical process controls to improve stability while meeting tolerance and surface finish requirements.
A countersink hole is a common yet easily overlooked detail in engineering design. It directly affects the flushness between fasteners and workpiece surfaces, as well as assembly reliability and operational safety. This article systematically reviews countersink geometry, standard dimensions, machining steps, and typical application scenarios, and also combines common errors and repair methods to help engineers make more reliable choices when designing and machining countersink holes.
Low-volume CNC machining provides a low-risk bridge between prototyping and mass production, delivering end-use parts in industrial materials and tolerances without investing in tooling.
This article compares riveting and welding across key engineering factors such as material compatibility, joint strength, weight, sealing performance, cost, and maintenance. It explains when each method is more suitable in real projects so you can choose the right joining process for your design.
Black anodized aluminum is a widely used surface finish for CNC-machined parts, combining a controlled aluminum oxide layer with black dye and sealing to improve durability and appearance. This article explains how black anodizing works, outlines its main advantages in wear resistance, corrosion protection, thermal emissivity, and light absorption, and clarifies important limitations related to UV exposure, chemical stability, temperature, and electrical insulation. It also discusses suitable aluminum alloys, process materials, and key design considerations such as dimensional growth, tolerance control, and batch color consistency. Typical applications and a comparison with black powder coating are provided to help engineers select an appropriate finishing process for their components.
Angle milling is a specialized milling method in which the tool cuts at a non-orthogonal angle to the workpiece surface, enabling precise inclined planes, dovetail guides, draft angles and other functional geometries. The article explains why designers use angle milling, how it is executed through workpiece tilting, spindle tilting or form cutters, and what types of angle cutters are available. It also reviews suitable materials, typical applications in machine tools, molds and aerospace parts, and the main advantages and limitations compared with conventional milling.
This guide explains the geometry, symbols, and applications of ten common hole types in machining, and shows how to choose the right hole based on function, assembly, and manufacturing cost.
