Deep Hole Drilling Purchase Agreement and Contract Terms

A standard purchase order is rarely adequate for a $200,000–1,500,000 machine tool. Payment milestones, delivery terms, acceptance criteria, and remedies for non-performance must be explicitly defined. The contract is your only protection if the machine does not perform as promised.

Essential Contract Clauses

Machine Specification

Clause ElementWhat It Should Include
Machine model and configurationExact model, options, accessories
Technical specificationsSpindle power, RPM range, coolant pressure and flow, axis travel
Control systemCNC make and model, software version
Included tooling and accessoriesStandard and optional tooling, first set of bushings
Excluded itemsWhat is NOT included (installation, foundations, tooling)
DocumentationType and format of manuals, schematics, drawings

Tip: Attach the full machine specification sheet as a schedule to the contract. Any change to the specification should require a written amendment signed by both parties. Verbal agreements about machine configuration are not enforceable.

Delivery Terms

TermWhat It Specifies
IncotermFOB, CIF, EXW, DDP (specify which version, e.g. Incoterms 2024)
Delivery dateSpecific date or range with delay penalties
Partial shipmentsAllowed or not
Shipping methodOcean, air, or land freight
Insurance responsibilityWho insures the machine during transit
Port of loading / dischargeSpecific ports
Customs clearanceWho handles import clearance and pays duties

Payment Structure

Payment MilestoneTypical PercentageCondition for Payment
Down payment (with order)30–40%Signed contract and proforma invoice
Progress payment20–30%Machine ready for FAT (Factory Acceptance Test)
Final payment before shipment20–30%FAT passed, machine ready for shipping
Balance after installation10–20%SAT (Site Acceptance Test) passed
ScenarioRecommendation
Established manufacturer, first machine30% down, 40% at FAT, 20% before shipment, 10% after SAT
New or unknown manufacturer20% down, 30% at FAT, 30% before shipment, 20% after SAT
Multi-machine orderStagger payments per machine, not blanket percentage
Machine with custom engineeringHigher percentage at FAT (50%) to cover engineering cost

Warning: Never pay 100% before the machine is delivered and accepted. A manufacturer who demands full payment before shipment is either financially distressed or unwilling to stand behind their machine. The SAT payment holdback is your only leverage if the machine underperforms after installation.

Acceptance Testing

Factory Acceptance Test (FAT)

FAT ElementWhat to Specify
LocationManufacturer's factory
DurationMinimum 1–3 days
Test part specificationMaterial, dimensions, tolerances
Test parametersSpeeds, feeds, coolant pressure, tooling
Measurement equipmentWhat will be used for verification
Passing criteriaSpecific numerical targets for each measurement
Witness rightsBuyer representative attendance
Non-conformance processWhat happens if the machine fails FAT

Site Acceptance Test (SAT)

SAT ElementWhat to Specify
TimingWithin 30 days of installation
Test partsSame specification as FAT or production parts
DurationMinimum 5 consecutive working days
Performance verificationRepeat FAT measurements on installed machine
Production runDemonstrate cycle time with actual production parts
Acceptance criteriaSame as FAT (machine must perform identically)
Sign-off procedureFormal acceptance certificate

Tip: Include a clause that the SAT acceptance test must be performed on the same test part specification used during FAT, using the same measurement methods. This prevents disputes about whether the machine meets specification after installation.

Performance Guarantees

GuaranteeWhat to SpecifyTypical Remedy
Cycle time guaranteeMaximum time per partLiquidated damages per second over target
Tolerance guaranteeDiameter, straightness, surface finishCorrective action at supplier cost
Uptime guaranteeMinimum availability percentageService credit or penalty
Power consumptionMaximum kW at specified conditionsCompensation if exceeded

Warranty Terms

Key Warranty Clauses

ClauseWhat It Should Include
Warranty period12–24 months from installation or 18 months from shipment
Coverage scopeParts, labour, travel, or combination
ExclusionsConsumables, normal wear, operator error, improper installation
Response timeGuaranteed response time for warranty service
Spare parts availabilityGuaranteed parts availability for minimum 10 years
Warranty transferabilityCan warranty be transferred if machine is sold?

FAQ

What payment terms are standard for deep hole drilling machine purchases?

30–40% down payment with order, 40% after FAT, 20% before shipment, and 10% after SAT. The final SAT payment holdback is critical — it gives you leverage if the machine does not perform as specified after installation.

Should I include liquidated damages for late delivery?

Yes. A delay penalty of 0.5–1% of the machine value per week of delay (up to a maximum of 5–10%) gives the manufacturer a financial incentive to deliver on time. Without liquidated damages, your only remedy for late delivery is to cancel the order and sue — which is impractical.

What is the difference between FAT and SAT?

FAT (Factory Acceptance Test) is performed at the manufacturer's factory before shipment. SAT (Site Acceptance Test) is performed at your facility after installation. The machine must pass both. FAT confirms the machine meets specification, and SAT confirms it performs correctly after installation.

Can I use my own purchase order terms instead of the manufacturer's contract?

You can try, but most manufacturers will insist on their standard terms for machine tools. The negotiation is usually about specific amendments to the manufacturer's terms, not a complete replacement. Focus on the critical items: specification, payment milestones, acceptance testing, and warranty.

How do I handle currency risk in international machine purchases?

Specify the contract currency and include a clause for how exchange rate fluctuations are handled. Common approaches: fixed exchange rate for the contract term, or a sharing mechanism (e.g., buyer absorbs first 2% change, remainder shared equally).
