2026-06-29 16:54What Should Be Included In A Complete Bridge CMM Quotation From China
When overseas buyers request a bridge CMM quotation from China, the quotation should include more than the machine price. A complete bridge coordinate measuring machine quotation should clearly list the machine model, measuring range, accuracy, probe system, software functions, fixture options, calibration certificate, factory acceptance test, export packaging, shipping terms, installation support, training, warranty, spare parts, and after-sales service. For buyers inspecting CNC machined parts, automotive components, aluminum housings, EV motor housings, gearbox parts, aerospace brackets, mold inserts, and precision industrial components, a detailed quotation helps avoid hidden costs and makes supplier comparison much easier.
Quick Answer
A complete bridge CMM quotation from China should include machine model, measuring range, accuracy specification, table load, probe package, stylus kit, calibration sphere, software modules, GD&T function, CAD import, automatic report, fixture support, calibration certificate, factory acceptance test, export packaging, delivery terms, installation guidance, training, warranty, spare parts, and after-sales service. Buyers should also provide drawings, CAD files, part size, tolerance requirements, measured features, destination country, and inspection workflow before requesting a quotation.
1. Why A Complete Bridge CMM Quotation Matters
Bridge CMM quotations from different suppliers may look similar at first, but the included configuration can be very different. One quotation may include only the basic machine body and standard software, while another may include probe accessories, GD&T software, calibration sphere, export packaging, installation guidance, training, and after-sales support.
If buyers only compare the final price, they may miss important cost items. After the machine arrives, they may discover that extra probes, stylus kits, software modules, fixtures, report templates, calibration tools, or service support are not included. This can delay installation and increase the real purchase cost.
A professional bridge CMM quotation should make the total inspection solution clear before the buyer pays a deposit.
2. Machine Model, Measuring Range And Accuracy
The first part of a complete quotation should clearly define the machine itself. Buyers should not accept vague descriptions such as “standard bridge CMM” without model, range, and accuracy details.
| Quotation Item | What Should Be Listed | Why It Matters |
|---|---|---|
| Machine Model | Exact bridge CMM model name or code | Prevents confusion when comparing suppliers |
| Measuring Range | X/Y/Z travel, such as 800x1000x600 or 1000x1500x800 | Confirms whether the machine fits the workpiece, fixture, and probe clearance |
| Accuracy | Accuracy specification, repeatability, and acceptance standard | Helps confirm whether the CMM can inspect the required tolerance |
| Table Load | Maximum workpiece and fixture load capacity | Important for heavy housings, castings, and fixtures |
| Machine Structure | Granite base, bridge structure, guideway, controller, air bearing if applicable | Shows the hardware level and long-term stability |
3. Probe Package And Stylus Accessories
Probe configuration is one of the most important parts of a bridge CMM quotation. A quotation that only says “with probe” is not detailed enough. Buyers should confirm the exact probe head, probe body, stylus kit, calibration sphere, and optional accessories.
Probe Package Should Include Clear Details
Probe head type: fixed, manual, or motorized
Probe body model and quantity
Renishaw probe option if required by the buyer
Touch-trigger probe or scanning probe configuration
Stylus ball size, stylus length, and stylus material
Extension bars, star styli, angled styli, and spare styli
Calibration sphere, base, and probe qualification accessories
Probe changer if automated inspection is required
Buyers inspecting deep bores, side holes, complex profiles, large housings, or mold inserts should pay special attention to stylus access. A low quotation may become unusable if the probe package cannot reach the real features.
4. Software Modules And Report Functions
Software is another area where hidden costs often appear. Some quotations only include basic measurement software, while others include CAD import, GD&T evaluation, automatic report generation, SPC output, scanning data processing, and custom report templates.
| Software Function | Should Be Marked As | Why Buyers Need It |
|---|---|---|
| CAD Import | Included / optional / not included | Useful for CAD-based programming and profile inspection |
| GD&T Evaluation | Included / optional / not included | Needed for position, flatness, profile, runout, coaxiality, and datums |
| Automatic Report | Report format should be shown | Supports customer approval and internal quality records |
| SPC Output | Included / optional / not included | Useful for batch production quality monitoring |
| Scanning Data Processing | Included only if scanning package is selected | Needed for profile, surface, and CAD comparison inspection |
5. Fixture Support And Application Review
A complete quotation should state whether fixture support is included, optional, or excluded. Many parts cannot be measured reliably if they are not located according to the drawing datum. This is especially important for aluminum housings, gearbox parts, EV motor housings, aerospace brackets, mold inserts, and thin-wall CNC components.
Fixture And Application Items To Confirm
Is modular fixturing included?
Is custom fixture design available?
Does the fixture follow the drawing datum structure?
Can the part be loaded repeatedly in the same position?
Can the probe access all critical features after clamping?
Will clamping force deform thin-wall aluminum or structural parts?
Is fixture cost listed separately or included in the package?
6. Calibration Certificate And Factory Acceptance Test
Before shipment, buyers should confirm whether the supplier provides calibration certificate, factory acceptance test, machine inspection records, probe qualification records, and pre-shipment photos or videos. These documents help buyers confirm that the machine has been checked before export.
| Quality Document | What It Should Prove |
|---|---|
| Calibration Certificate | Machine accuracy has been verified according to stated conditions |
| Factory Acceptance Test | Machine function and basic performance were checked before shipment |
| Probe Qualification Record | Probe and stylus setup can be qualified correctly |
| Pre-Shipment Photos Or Video | Machine configuration, accessories, and packaging can be reviewed before delivery |
7. Export Packaging, Shipping Terms And Documents
For overseas buyers, export packaging and shipping documents are part of the real quotation. A bridge CMM is precision equipment, so the machine body, granite table, controller, computer, probe package, accessories, calibration tools, and documents must be protected during transportation.
Export Items A Quotation Should Include
Export-grade wooden case packaging
Moisture protection, shock protection, and accessory protection
Packing size, gross weight, and loading method
Commercial invoice, packing list, user manual, and warranty document
Delivery term: EXW, FOB, CIF, DAP, or DDP if available
Estimated production lead time and shipping preparation time
Pre-shipment packing photos if required
8. Installation, Training, Warranty And After-Sales Service
After the CMM arrives, buyers still need installation, leveling, air supply connection, power check, software setup, probe qualification, calibration verification, operator training, and troubleshooting support. These service items should be written clearly in the quotation.
| Service Item | What Buyers Should Confirm |
|---|---|
| Installation Guidance | Remote video support, installation manual, site preparation guide |
| Operator Training | Machine operation, probe qualification, software use, report generation |
| Software Support | Program setup, GD&T report guidance, troubleshooting support |
| Warranty | Warranty period, covered parts, excluded items, and response method |
| Spare Parts | Availability of probe accessories, styli, controller parts, and service parts |
9. Payment Terms, Validity And Delivery Time
A complete bridge CMM quotation should also state commercial terms clearly. This helps buyers plan procurement, payment, delivery, and installation schedule.
Commercial Terms To Include
Quotation currency
Payment terms and deposit requirement
Quotation validity period
Production lead time
Delivery term and shipping responsibility
Package size and estimated shipping weight
Warranty period and service scope
Optional items and price difference
10. What Buyers Should Provide Before Requesting A Complete Quotation
To receive an accurate bridge CMM quotation from China, buyers should provide complete application information. Without drawings, part size, tolerance, and measured feature details, the supplier can only offer a rough machine recommendation.
Buyer Information Checklist
Part drawings and CAD files
Maximum part length, width, height, and weight
Material, machining process, casting process, or surface condition
Critical dimensions, tolerance requirements, and GD&T items
Measured features: holes, bores, planes, profiles, slots, side features, sealing faces, and datum planes
Fixture height, clamping method, and loading method
Inspection purpose: FAI, PPAP, batch inspection, final inspection, export inspection, or customer approval
Required probe package, software report, SPC output, and CAD comparison need
Destination country, delivery term preference, installation environment, and service expectations
11. Common Quotation Comparison Mistakes To Avoid
Comparing only the total price without checking what is included.
Accepting a quotation without exact machine model and measuring range.
Ignoring probe head, probe body, stylus kit, and calibration sphere details.
Assuming CAD import, GD&T software, and SPC output are included by default.
Forgetting fixture cost and repeatable part location requirements.
Not confirming calibration certificate and factory acceptance test.
Ignoring export packaging, shipping terms, and documentation.
Not writing installation support, training, warranty, and after-sales response into the quotation.
Paying a deposit before confirming optional items and hidden costs.
