One drawing. A considered manufacturing route.
CNC machining removes material to form the features your assembly needs. A part may combine milling, turning and secondary work. Start with its geometry, then review material, quantity and critical interfaces together.
Molitech quotes and supplies the finished parts as your contracting seller. Liwen follows drawing questions, production issues and agreed inspection records with independent manufacturers. Drawing revision, material, inspection scope and the delivery plan are confirmed for the order.
Choose by the geometry that matters.
Diameters around a common axis
Shafts, bushes, sleeves and rings: review fits, threads and specified feature relationships.
Explore cnc turning →Several faces or angled access
Multi-face features and curved surfaces: assess orientation, clamping and whether indexing is sufficient.

ReviewLiwen follows your agreed requirements
A close fit needs a clear requirement. Tell us what must fit together, whether dimensions apply before or after treatment, and which features need inspection records.
Material requirements for
CNC machining.
Specify the grade, condition and any certification needed. Grade and availability confirmed with your quotation.
Finishing and secondary operations for
CNC machining.
As machined
Identify functional surfaces and any specified roughness.
Steel-shot blasting
Specify surface texture, masking and cosmetic acceptance. Suitability and the treatment scope are confirmed for the part.
Anodising
State the coating requirement and finished dimensions; the route is assessed for the alloy.
Other finishes
Polishing, brushing, painting, plating, powder coating and marking are enquiry options.
Material and packaging requirements
Tell us about material, packaging or documentation requirements so they can be included in your quotation.
Discuss your requirements →From route selection to the finished part.
Send the released drawing, material, quantity, destination and required delivery date.
Identify which features call for milling, turning, multi-axis access or secondary operations.
Agree tolerances, finish, inspection records and the delivery plan before production.
Liwen coordinates questions with the manufacturer; parts and agreed records follow the order.
When a part
needs review.
Send the order or batch, photographs and measurement basis. Molitech reviews the concern and coordinates an investigation with the manufacturer.
The agreed acceptance standards determine the solution. Rework, replacement, costs and timing follow the order agreement.

Manufacturing & Inspection Review Before Production
Carry clear requirements from drawing to acceptance. Liwen coordinates questions with the independent manufacturer; review scope and records are agreed for your order.
Drawing review
Identify the drawing revision, key dimensions, datums and functional interfaces. Flag missing or conflicting requirements for customer clarification.
Manufacturability
Review tool access, workholding, thin walls and difficult features with the proposed independent manufacturer. Customers approve any proposed design changes.
Tolerance risk
Distinguish functional fits and feature relationships from general requirements. Assess demanding tolerances for the particular part and route.
Inspection alignment
Agree the measurement basis for critical features, required records and any sampling or acceptance criteria in the order. Resolve different measurement interpretations before production.
Cost options
Discuss possible changes to material, geometry, finish or quantity against function and inspection requirements. Savings are assessed for the project rather than guaranteed.
Customer confirmation: unresolved requirements, proposed design changes and acceptance arrangements need your approval before the affected work proceeds. Molitech remains your contracting seller.
CNC machining FAQs
How are multi-face features handled?
Identify datums, critical relationships and access-sensitive features. The manufacturer reviews tool access, workholding and the number of setups.
What should I specify for inspection?
State the acceptance dimensions and the measurement or reporting requirements. CMM or first-article records are agreed in the order rather than assumed for every part.
How do I request a quote?
Send the drawing revision, material, quantity, destination and target delivery date. Use an authorised link or agree a confidential email route with Liwen.
What tolerances and lead times can you offer?
The drawing and selected route define the tolerance review. Quotation within 24 hours. Production lead time: 10–15 days to dispatch. Delivery according to the agreed schedule. Precision requirements are reviewed for the part.
Who is responsible for my order?
Molitech quotes, contracts and receives payment as your seller. Independent partner manufacturers produce the parts.
Which dimensions should I highlight?
Mark the dimensions that affect fit or function, and say whether they apply before or after finishing. This helps the manufacturing and inspection discussion focus on your part.
Not sure which route fits?
Send the complete drawing. Liwen will coordinate a part-specific route review and quotation.
