MasterCNC Tech supports overseas OEM buyers sourcing custom CNC machined parts from drawings. We review part geometry, material, tolerance, quantity, and inspection requirements before quotation.
Brass Components
Sleeves, collars, threaded parts, and fittings are reviewed for material and thread requirements.
Steel Sleeves and Spacers
Bores, grooves, outer diameters, and burr control are checked against the drawing.
Stainless Connectors
Threaded connectors and adapters are reviewed for fit, edge condition, and surface protection.
What is this service
This page is for buyers who need one supplier contact for CNC turning, CNC milling, threading, drilling, tapping, deburring, inspection, and production coordination.
What we can do
- Drawing review before quotation
- CNC turning and CNC milling sourcing support
- Prototype, small batch, and repeat production review
- Inspection planning for critical dimensions
Materials
- 304 / 316 stainless steel
- Carbon steel and alloy steel
- Aluminum alloys
- Brass, copper, and bronze
- Selected engineering plastics after review
Tolerance / Precision
Typical tolerance can reach +/-0.01mm on suitable features after drawing review. Final tolerance depends on geometry, material, feature size, and inspection method.
Typical parts
- Shafts and pins
- Bushings and sleeves
- Threaded fittings and connectors
- Aluminum housings and brackets
- Small custom precision components
Industries
- Industrial machinery
- Automation equipment
- Mechanical assemblies
- OEM replacement parts
- Prototype development
Lead time
Simple RFQs are usually reviewed within 24 hours when drawings, material, quantity, and tolerance requirements are complete.
Buyer note
Best fit: buyers who need drawing-based custom machining rather than catalog parts.
RFQ Checklist
- 2D drawing with critical dimensions and tolerance notes.
- STEP, STP, IGES, PDF, DXF, DWG, or sample photos.
- Material grade, quantity, surface finish, and target delivery date.
- Thread standard, heat treatment, coating, or inspection report needs when required.
Inspection Focus
- Critical diameter, length, hole position, thread fit, or flatness according to drawing.
- Visual check for burrs, surface defects, scratches, and packing condition.
- Caliper, micrometer, gauges, thread gauges, or other suitable tools based on feature type.
- Inspection report can be discussed before production when buyers require documentation.
Engineering Notes Before Quotation
- Tight tolerance depends on material, geometry, feature size, setup method, and inspection method.
- Long shafts, thin walls, deep pockets, and complex threads need manufacturability review before price confirmation.
- Separate critical and non-critical dimensions to avoid unnecessary machining cost.
- Complete RFQ information helps us review cost, lead time, and production risk faster.
