DFM feedback before production
In-process inspection for key features
CMM / FAI reports available on request
Stable lead times and secure packaging
Upload your drawings, get DFM feedback and a quote, then we machine, inspect, and ship.
Send STEP/IGES/PDF and key requirements (material, tolerance, finish, quantity).
We confirm manufacturability and share a fast quote with lead time.
Production starts after approval. In-process checks ensure stable quality.
Final inspection, protective packaging, and safe shipping. Reports available on request.
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.

In stainless steel CNC machining, 18-8 and 303 are often used for different types of parts. 18-8 is more suitable for general fasteners and corrosion-resistant structural components, while 303 offers better machinability and is commonly used for automatic lathe parts, shafts, and small precision components.
In many steel, mold, and precision mechanical parts, soft machining is used before heat treatment to remove most of the excess material and create the basic part geometry. This article explains how soft machining works, which tools are commonly used, what types of parts it suits, and why machining allowance and late
CNC machining lead time is not determined only by machine run time. It is also affected by material availability, drawing completeness, tolerance requirements, inspection documents, and post-processing steps. This article helps purchasing teams understand where lead time comes from, estimate typical delivery cycles, and reduce project delay risks.
This article explains the main components of CNC machining cost, including material, programming, setup, machine time, tooling, inspection, and post-processing. It also shows how to reduce custom part pricing through better geometry, practical tolerances, and complete technical documentation.
This article introduces the role of CAM (Computer-Aided Manufacturing) in CNC machining, explaining how it converts CAD models into toolpaths and G-code while covering the CAM workflow, key benefits, industry applications, common software tools, and required skills.
This article introduces common CAD file formats used in CNC machining and key design preparation tips, helping you submit 3D models and 2D engineering drawings more effectively while reducing communication issues during quoting, programming, and production.
CAD is an important tool that connects design ideas with real-world manufacturing. This article introduces its definition, main types, applications, and commonly used software.
Grooving machining is a common cutting process in CNC machining, often used for sealing, positioning, lubrication, and assembly features. This article systematically explains the definition, process, OD/ID/face groove types, common tools, chip control, and design considerations for grooving machining.
This article introduces the main processes, common materials, and manufacturing challenges in CNC shaft machining, covering turning, milling, drilling, threading, heat treatment, grinding, and surface finishing to help engineers understand key manufacturing considerations for shaft components.
Iron can conduct electricity, but it is not a high-conductivity material. This article explains in simple terms why iron conducts electricity, how it differs from metals such as copper and aluminum, and when iron conductivity matters in practical industrial parts.
This article explains the basic concept of CNC machining tolerances, common tolerance ranges, major tolerance types, and the key factors to consider when choosing tolerances, including part function, material, machining method, and inspection requirements. It helps designers and buyers understand how to set reasonable machining tolerances for CNC parts.
This article explains the common challenges of thin-walled parts in CNC machining, including machining deformation, clamping distortion, vibration, residual stress, and tolerance control. It also explains how proper workholding, gradual material removal, cutting force control, optimized toolpaths, and finishing strategies can improve machining stability for thin-walled components.
To prepare a quote, we usually need:
If you only have a sample or rough sketch, you can also send it to us and our engineers will help you define what is needed.
For most CNC machining projects, we provide DFM feedback and a quote within 1 business day after receiving complete information. Complex parts or large RFQs may take slightly longer.
We commonly machine:
If you have a special material, please contact us and we will check machinability and lead time.
For standard CNC machining parts we typically work to:
The achievable tolerance depends on material, geometry, and inspection method.
Typical lead times are:
If you have an urgent project, let us know your target schedule and we will check the fastest feasible plan.
Yes. We can provide CMM/FAI reports, material certificates, and other inspection documents on request. All customer drawings, models, and data are treated as strictly confidential and are only used for manufacturing your parts.
