Machined parts for your next machine.
Great Machining is a CNC machining supplier for custom metal and plastic parts. Send a drawing or describe the bracket, housing, shaft or fixture plate your equipment needs.
For industrial equipment, automation and instrument teams moving from a prototype to repeat orders.
Find the shape your project needs
Illustrative part examples. Your drawing defines the final geometry.
Brackets & mounts
Sensor mounts, camera brackets and structural connectors. Identify the mounting faces, hole positions and clearance your assembly needs.
Housings & enclosures
Instrument bodies, covers and pocketed blocks. Highlight mating interfaces, internal clearances and surfaces that need a defined appearance.
Shafts & spacers
Short shafts, sleeves and stepped round parts. Specify the fit diameters, shoulders, threads and surfaces that locate or move against another part.
Fixture plates & locating parts
Tooling plates, locating blocks and sample supports. Define the datums, locating holes and mounting pattern that position the assembly.
A manufacturing route that follows the geometry
CNC machining and dimensional inspection are handled in-house. Specialist finishing and additional manufacturing processes can involve selected production partners. Include any manufacturing-location or subcontracting restrictions with your enquiry.
CNC milling
A starting route for plates, brackets, housings and parts with pockets or features on several faces. Tool access and how the part can be held affect the manufacturing plan.
CNC turning
A starting route for shafts, sleeves, spacers and other round parts. Cross-holes, flats or off-axis features may need an additional milling operation.
From prototype to repeat order
Tell us whether you need a fit-check prototype, a first batch or scheduled repeat supply. Include the drawing revision and quantity for each part so the quotation can address the current stage.
Parts that belong in your equipment
Automation & special machines
Mount a sensor, locate a camera, connect an actuator or position a workpiece. Start with the interfaces that determine fit in the machine, then identify the material and finish.
Instruments & test equipment
Support a sample, house an assembly or locate a test fixture. Describe the operating environment and any cleanliness or documentation requirements that affect the part.
Agree the details that determine the finished part
Material
Specify the grade, condition and stock form when known. Aluminium is a useful starting discussion for brackets, plates and housings; steel, stainless steel, brass and engineering plastics depend on the part’s function and specification.
Fit & finish
Mark critical mating surfaces and say whether the dimension applies before or after finishing. Identify cosmetic faces and masking requirements instead of treating every surface the same.
Inspection
Identify the critical features and requested records with the enquiry. Dimensional reports, material documentation and first-article scope need to be agreed for the specific order.
Put your next part in motion
Send a drawing or a short part description, plus quantity and material if known. Add critical dimensions, the finish, requested documents and delivery country when available. If the material or process is still open, explain what the part must do.
Opens your email application. Attach CAD and drawings there, or ask about an NDA before sharing sensitive files.
Before you send your enquiry
Which files are useful?
A STEP or IGES model describes the geometry. A PDF drawing can define tolerances, threads, material, finish and the drawing revision. A part description is enough to start a preliminary discussion if your files are not ready.
Can I discuss a single prototype?
Send the quantity and what the prototype needs to validate. The manufacturing route, material purchase and any special setup are assessed for the individual part.
Should I specify a tolerance on every feature?
Identify functional fits, datums and other critical requirements clearly. General tolerances and the inspection scope should be agreed with the drawing; the tightest available tolerance is not a useful blanket requirement for every surface.
Does manufacturing lead time include shipping?
Production, finishing, inspection, customer approval and transport are separate scheduling inputs. Ask for the required dispatch and delivery dates to be addressed in the quotation.
