Precision CNC Machining vs. Standard CNC Machining Services
First Mold's precision CNC machining goes far beyond standard machining processes. This service is applied for precision mold making, aerospace and medical protypes.
This service is applied for precision mold making, aerospace and medical prototypes. Precision CNC machining does cost more upfront because it uses advanced multi‑axis machines, special tools, and strict temperature and dust control. But it gives you huge value in return. It eliminates assembly mistakes and ensures every part is exactly the same. That means lower production risks and much lower costs over time.

Applications of Precision CNC Machining Services
Curently, about 31% of our precision machining work is making molds and dies. Another 16% goes to automotive precision parts. The rest of our capacity is used for critical jobs in optical communications, medical device, and aerospace industries.
Mold Components Making
First Mold uses advanced multi-axis machines from GF+, 牧野そして Haas to precisely control the mold cavity and core in four key areas: dimensions, shape, position, and surface finish. The accuracy in these areas directly determines the accuracy of the final injection-molded or die-cast parts.

First Mold’s Precision Machining Features
Standard CNC machining services are suitable for parts with less strict processing requirements. First Mold’s precision CNC machining services achieve extreme performance in wall thickness, micro-machining, geometric structures and other dimensions.
Precision Metrics
寸法公差
These extreme precision values mostly apply to precision mold fabrication.
表面粗さ
Minimize or completely eliminate costs associated with secondary polishing.
GD&T
We commit to providing a complete First Article Inspection (FAI) report.
Structural Extreme Capabilities
Deep Hole Machining
We can machine deep cavities and holes up to 10:1 aspect ratio.
Micro-Machining
We can produce Ø0.1mm micro-holes and intricate internal geometries
Thin Wall Machining
We can achieve 0.8mm ultra-thin walls.
Machining Equipment and Inspection Facilities For Precision
Our precision CNC services are built upon the efficient synergy between standard‑grade and high‑end tools. We operate dozens of BF standard machines, along with around 15–20 high‑end models including Haas, Makino and GF+.
Precision Promise By QC System
3D CMM Inspection
CMMs serve as the definitive authority for verifying complex 3D geometries and tight geometric tolerances.
Non-Contact VMM Inspection
VMMs capture highly deformable flexible materials, ultra‑thin wall thicknesses, and micro‑scale small holes.
Z Axis Height gauges
Height gauges verify blind‑hole depths and critical vertical dimensions of stepped surfaces.

FAQ for Precision CNC Services
精密CNC加工プロジェクトの見積もりを行うには、どのような3D CADファイル形式が必要ですか？
3Dソリッドモデルまたはサーフェスモデルは、STEP（.stp/.step）またはIGES（.igs/.iges）形式で当社へお送りいただくことをお勧めします。これ以外の形式の3Dファイルをご提供いただいた場合、後日、寸法に関する詳細情報をお伺いさせていただくことがあります。.
図面を提出してから、正確な見積もりが届くまでどれくらいかかりますか？
First Moldのシニアエンジニアリングチームは、通常、24時間以内に詳細な見積書と、初期段階のDFM（製造適性設計）に関する提案をご提示いたします。多軸ミルターン加工を必要とする、あるいは加工が困難な特殊な材料が使用される特に複雑な部品については、遅くとも2営業日以内にご回答いたします。.
御社のDFM分析にはどのような内容が含まれていますか？
当社の精密CNC加工サービスでは、「精密グレード」のDFM解析を提供しています。 これには、厳しい公差（±0.005 mmまで）の実現可能性、微細構造（薄肉、深穴、微細穴など）の製造可能性、材料の応力および変形の予測、ならびにコスト削減と効率化のための設計提案が含まれます。.
特殊素材の精密加工は可能ですか？
Absolutely. First Mold has the proven capability to machine:
Superalloys: Inconel 718/625, Hastelloy C276, Waspaloy, etc.
Titanium Alloys: Grade 5 (Ti-6Al-4V), Grade 2, and many aerospace-grade titaniums, expertly handling challenges like tool deflection, springback, and work hardening.
High-performance Polymers: PEEK (including 30% glass-fiber or carbon-fiber reinforced), PEI (Ultem), PPS, etc., delivering precision parts free of burrs and stress cracking.
精密受託製造において、顧客が独自に特別に認証を受けた原材料を持ち込むことは可能ですか？
はい、弊社では常にお客様による材料の持込みを歓迎しております。その際、材料の完全な証明書（ミル証明書）およびロット番号／ヒート番号を事前にご提供いただく必要があります。材料がファーストモールドに到着次第、弊社にて入荷検査を実施いたします（契約内容に基づき、XRFによる成分検査や機械的特性試験などが含まれる場合があります）。.
表面処理工程は、社内で実施していますか、それとも認定を受けた外部パートナーに委託していますか？
ファーストモールドの自社工場では、研磨、レーザー彫刻・マーキング、スクリーン印刷、粉体塗装などの表面処理を自社で直接行うことができます。 電気めっきや陽極酸化処理などの工程については、10年以上にわたり提携している外部パートナーに全面的に委託しており、これらのパートナーはNadcap、ISO 13485、AS9100などの専門認証を取得しています。.
当社が受け取った精密部品が入荷検査に合格せず、図面の公差を満たしていない場合、貴社の対応および交換手続きはどのようになっていますか？
We pursue a “zero defect” quality goal, and all precision parts leave our factory with a full dimensional report from a CMM (Coordinate Measuring Machine) or video measuring system. If you confirm any out-of-tolerance condition during your inspection, First Mold will take the following steps:
Please contact our quality engineer within 24 hours of discovering the issue and provide your inspection data. We will immediately quarantine the same batch and start a root cause review.
Once confirmed as our responsibility, without waiting for the parts to be returned, we will immediately and with the highest priority re-manufacture conforming parts free of charge under the fastest lead time, and cover all shipping costs.
The non-conforming parts can be returned to us for a thorough root cause analysis, or scrapped according to your instructions. This incident will be recorded in the product’s permanent process control file (PFMEA update) to systematically prevent the same issue from recurring.
What are your standard lead times for rapid prototyping and low-volume production of precision CNC parts?
Rapid prototyping: Standard lead time is 4-7 working days.
Low-volume production: Standard lead time is 7-15 working days.
Do you offer assembly services for precision CNC parts?
At the moment, we do not offer full product assembly. If the assembly process is very simple, we may be able to do it for you.
