How Do You Start Cnc Machining If You'Ve Never Done This Before?
You're starting CNC machining with no experience-validate Tier 2 Aerospace and Class III Medical Device customers first, and secure certified alloy supply with traceability before you quote fixed-price contracts; see pricing context How Much Does a CNC Machining Business Owner Earn?. Design one prototype production workflow targeting 10 to 50 units monthly and budget initial capex of $4,350,000 per the assumptions. Plan to reach breakeven by Year 4 based on the provided revenue ramp and align certifications early so you don't stall; defintely lock supply first.
First moves to start
Validate Tier 2 aerospace and Class III medical customers
Secure certified alloy supply with traceability
Design prototype workflow for 10-50 units/month
Budget initial capex of $4,350,000 and target breakeven Year 4
What Should You Do First Before Spending Any Money?
Start with low-cost validation steps that de-risk capex and sales so you don't buy machines before customers or certified alloy are secured. Run a certified material waste audit that guarantees a 15 percent TCO reduction, validate the AS9100 or ISO 13485 certification path, and model Year‑1 revenue against the $2,000,000 initial machine capex; also get quotes for the $1,000,000 certified alloy inventory and confirm lead customers ready to sign $5k-$50k recurring contracts.

First actions before capex
Run certified material waste audit - guarantee 15% TCO
Validate AS9100 or ISO 13485 certification path
Obtain certified alloy quotes totaling $1,000,000
Model Year‑1 revenue vs $2,000,000 machine capex and secure $5k-$50k LOIs
How Long Does It Usually Take To Get Open?
You'll typically open in stages, so plan dates and cash accordingly - keep reading for the exact timeline and next steps. The factory fit-out and cleanroom complete by end of March 2026, and the initial 5-axis CNC fleet is delivered and installed between January and June 2026. Digital Twin development runs through December 2026 with commisioning, and certification plus traceability hardware deployment also finish by December 2026. Allow 6 to 12 months after those milestones for customer validation and initial recurring contracts; see How to Write a Business Plan for CNC Machining Success?

What Mistake Delays Most First-Time Owners?
You're most often delayed by five avoidable operational gaps. Fix underfunded certified alloy inventory, move critical certifications in-house, deploy material traceability, stop pricing low-volume work as commodity, and hire sales to convert certified waste audits into contracts; see 5 KPI & Metrics for CNC Machining Success: What Should You Be Tracking? for priorities. Do these and you remove the main blockers to opening a CNC machining startup.
Relying on generalist subcontractors over in-house certs
Ignoring certified material traceability required by customers
Pricing as commodity instead of fixed-price low-volume
What Are 7 Steps To Open Cnc Machining?
Step 1 - Validate Market And Secure Anchor Customers
For cnc machining the goal is to secure anchor customers and letters of intent so 'done' looks like signed LOIs for 10-50 units/month and a trial certified waste audit scheduled.
What to Do
Call R&D and production engineers at Tier 2 aerospace and Class III medical device firms
Offer a free certified material waste audit that guarantees 15 percent TCO reduction
Draft and send letters of intent (LOIs) for recurring low-volume runs
Price sample fixed-price contracts for 10-50 units/month
Use LOIs to justify ordering initial certified alloy inventory
What You Should Have
Signed LOIs for recurring low-volume production
Scheduled certified waste audit reports and findings
Vendor quote or purchase approval for initial certified alloy inventory
What It Depends On
Customer availability and willingness to sign LOIs
Time to schedule and complete certified waste audits
Supplier lead time and terms for certified alloy inventory
Common Pitfall
Waiting for full certification before LOIs --> delays buying alloy and slows production start
Create a one-page certified waste audit offer to convert one pilot customer this week / speeds LOI signings
Order a vendor quote for initial certified alloy lots to prove pricing and lead time / enables capex decision
Step 2 - Lock Supply Chain And Traceability
You're buying certified alloy and traceability before production starts; done looks like contracts signed, $1,000,000 of certified alloy stocked, and traceability hardware scheduled for deployment.
What to Do
Negotiate certified-alloy terms and lot-trace clauses
Order initial alloy inventory to match assumptions
Specify and buy traceability hardware and scanners
Integrate lot-control fields into ERP or MES
Test inbound traceability with a pilot lot
What You Should Have
Signed supplier contracts with traceability terms
Inventory receipt for $1,000,000 certified alloy
Traceability hardware order and integration plan
What It Depends On
Supplier lead times and minimum order quantities
Traceability hardware delivery and install by December 2026
Regulatory requirements for AS9100 or ISO 13485 lot control
Common Pitfall
Buying generic alloy without trace certificates --> production stops and failed audits
Delaying software integration --> manual lot tracking, errors, and rework
Quick Win
Create a one‑page supplier spec sheet to speed quotes and prevent non‑conforming alloy receipts
Step 3 - Build Out Micro-Factory And Equipment
Goal: Finish the micro-factory fit-out, install 5-axis CNCs and metrology, and hand over a certified production cell where 'done' is live production with traceable material and scheduled maintenance.
What to Do
Confirm cleanroom spec and sign contractor
Order 5-axis CNC machines for Jan-Jun 2026 delivery
Price and order precision metrology and CMM by July 2026
Set maintenance and calibration contracts from day one
Integrate lot-traceability hardware into the production cell
What You Should Have
Signed fit-out contract meeting regulatory cleanroom spec
Purchase orders for 5-axis CNCs and metrology equipment
Maintenance & calibration schedule and vendor SLAs
What It Depends On
Vendor lead times for 5-axis CNCs and CMMs
Completion of the factory fit-out and cleanroom by March 2026
Funding availability to cover the $2,000,000 machine capex and related spend
Common Pitfall
Underordering certified alloy storage before machines arrive --> production stops and delayed customer runs
Skipping calibration schedules to save cost --> failed inspections and rework
Quick Win
Create a one-page installation checklist to speed vendor acceptance and prevent rework
Draft a maintenance contract template this week to lock calibration windows and avoid downtime (reduces first-year downtime)
Step 4 - Develop Digital Twin And Workflow Systems
Goal: Build a capitalized digital twin and live workflow that controls inventory, drives waste down, and proves a >98% first-pass yield; done looks like a commissioned digital twin running pilot production through December 2026.
What to Do
Define digital twin scope and success metrics
Integrate real-time inventory and traceability feeds
Implement waste-reduction algorithms into workflow
Run pilot production to validate first-pass yield
Price and package a subscription offer for customers
What You Should Have
Capitalized development plan through December 2026

Subscription pricing sheet and SLA for workflow access
What It Depends On
Completion of digital twin dev by December 2026
Availability of traceable certified alloy inventory for pilot runs
Integration with shop floor metrology and CMM data streams
Common Pitfall
Rushing integration --> inaccurate yields and rework
Not linking traceability --> regulatory non-compliance and lost contracts
Quick Win
Create a pilot-run checklist to prove first-pass yield target and stop rework
Build a one-page subscription offer to present to anchor customers and speed early sales
Step 5 - Hire Compliance, Sales, And Technical Staff
Goal: Staff the micro-factory so AS9100/ISO 13485 compliance, certified waste audits, and conversion to recurring $5k-$50k fixed-price contracts are operational and auditable; done looks like QA, sales, and technical teams hired and onboarding together.
What to Do
Hire QA and Compliance Manager (AS9100/ISO 13485)
Recruit 2 Technical Account Managers to convert audits
Scale Head of Sales FTEs per hiring plan
Budget CEO and CFO salaries into fixed wage line
Coordinate joint onboarding for sales and compliance
What You Should Have

Budgeted wage schedule including CEO and CFO
Onboarding timeline linking compliance checkpoints to sales
What It Depends On
Certification timeline for AS9100 or ISO 13485
Availability of experienced compliance and TA hires
Funding to cover salaries until recurring revenue ramps
Common Pitfall
Hiring sales before QA --> delayed customer sign-offs and rework
Underbudgeting CEO/CFO wages --> cash strain versus planned capex of $4,350,000
Quick Win
Create a one-page compliance checklist to speed audits / prevents rework
Draft TA outreach script and convert first pilot audit into LOI / validates $5k-$50k deal size
Expect significant upfront capital primarily for machines and inventory The assumptions list $2,000,000 for 5-axis machines, $1,000,000 for initial certified alloy inventory, and $400,000 for factory fit-out, totaling $3,400,000 in major capex items include additional traceability and metrology spend per the capex schedule
Breakeven is projected in Year 4 per core metrics Revenue ramps from $1,200,000 in Year 1 to $9,000,000 by Year 4, with EBITDA turning positive in Year 4, so plan operations and cash runway to bridge the negative EBITDA years
Yes you need in-house certifications for regulated customers The business model requires AS9100 or ISO 13485 compliance to eliminate outsourcing delays and meet customer requirements, and certification timelines are reflected in the operating plan and fixed expense budget
Prioritize the highest-impact streams first start with fixed-price recurring contracts at launch, then add certified waste audits and phased subscriptions The assumptions schedule shows five revenue streams phased across 2026 to 2026 to 2026 launch windows
Major cash risks include large upfront capex and inventory purchases, the minimum cash trough in Jan 2028, and delayed customer conversions monitor capex of $4,350,000 and revenue ramp from $1,200,000 to $9,000,000 to avoid liquidity shortfalls
