How We Control Quality Throughout Machining

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.

Process-Wide Quality Control

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.

Professional Equipment & Inspectors

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.

Documentation & Quality System

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.

Quality Inspection in CNC Machining: A Complete Guide

Whether a CNC-machined part meets drawing requirements depends on effective quality inspection and process control. This article explains the complete inspection process, from incoming material and first-article inspection to in-process and final inspection, as well as common measuring tools such as coordinate measuring machines (CMMs), calipers, micrometers, and surface roughness testers. It also covers the role of inspection reports and traceability records in part acceptance.

What Is GD&T? Geometric Dimensioning & Tolerancing Explained

Geometric dimensioning and tolerancing, usually shortened to GD&T, is a symbolic language for defining geometry on engineering drawings. It covers more than size, spelling out the allowable form, orientation, location, and runout of each feature so a designer, a machinist, and an inspector read the same requirement. Conventional plus/minus dimensions leave real geometry open to…

Clearance transition and interference fit comparison
Types of Fits: Clearance, Transition, and Interference Explained

A transition fit is an engineering fit in which the shaft and hole tolerance zones overlap, so the assembled parts may end up with a small clearance or a slight interference depending on the actual machined sizes. It is used when a component must be positioned precisely but still be assembled and disassembled without force, such as locating pins, gear hubs, and bearing assemblies. On drawings, it is specified with ISO codes such as H7/k6. Choose a transition fit for precision location with light-force assembly; use an interference fit for permanent high-load joints and a clearance fit for free movement.

Bilateral vs Unilateral Tolerance: What’s the Difference?

Every dimension on a drawing needs a tolerance, and the type you choose matters as much as the number. A bilateral tolerance like 10.00 ±0.05 allows variation on both sides of nominal. A unilateral tolerance like 10.00 +0.05/-0.00 allows it on one side only. The choice is not a style preference: it controls whether a…

How to Clean CNC Machined Parts: Process, Materials and Common Mistakes

CNC machined parts often retain cutting fluids, oil, and metal chips on their surfaces after turning, milling, or five-axis machining. If these residues are not thoroughly removed, they can affect dimensional inspection and assembly, and may also lead to rust, stains, or customer acceptance issues during transportation. This article explains the standard cleaning process for CNC machined parts, cleaning considerations for aluminum, steel, and copper, common cleaning mistakes, and how manufacturers integrate cleaning into their quality control process.

MinHe CNC Machining FAQ

What information do you need to prepare a CNC machining quote?

To prepare a quote, we usually need:

  • 2D PDF and/or 3D models (STEP/IGES/STP)
  • Material or grade
  • Required quantity (per order / batch size)
  • Surface finish and any post-treatment (anodizing, plating, etc.)
  • Critical dimensions or key tolerances (if they are not standard)
  • Any special requirements such as inspection reports, packaging, or labeling

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.

How fast can I get DFM feedback and a quotation?

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.

What materials can you machine?

We commonly machine:

  • Aluminum alloys (e.g. 6061, 6082, 7075, etc.)
  • Stainless steels (304, 316, 17-4PH, etc.)
  • Carbon and alloy steels
  • Brass, bronze, copper
  • Engineering plastics (POM, PEEK, PTFE, etc.)

If you have a special material, please contact us and we will check machinability and lead time.

What tolerances can you achieve?

For standard CNC machining parts we typically work to:

  • General tolerances: ±0.05 mm
  • Tighter tolerances on key dimensions on request, after DFM review

The achievable tolerance depends on material, geometry, and inspection method.

What are your usual lead times for prototypes and production?

Typical lead times are:

  • Prototypes and small batches: about 7–10 days
  • Medium and large production: according to quantity and process flow

If you have an urgent project, let us know your target schedule and we will check the fastest feasible plan.

Can you provide inspection reports, and will my drawings remain confidential?

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.
