Input data
Material, drawing or model, casting condition, quantity and requested timing in the enquiry.
From machining allowance to the required delivery condition
Rough machining establishes the initial shape while leaving material for subsequent stages. Finish machining brings specified surfaces to the agreed dimensions and drawing requirements.
Not every casting surface must be machined. Mark functional surfaces and datums on the documentation, together with areas that are to remain as cast.
The drawing defines the result
A review requires the material, geometry, final dimensions, tolerances and surface texture when specified. Measurement datums, coaxiality and the relationship between surfaces also matter when they are called out on the drawing.
For a casting intended for machining, allowances and the reference between the as-cast and finished conditions must be agreed. Missing requirements are not replaced with assumed default values.
- material grade and component condition before machining
- versioned 2D drawing or 3D model with units
- surfaces to be machined and the selected datums
- final dimensions, geometrical tolerances and surface texture when applicable
- quantity, required delivery condition and acceptance criteria
Casting and machining agreed together
When METAL-KOLOR also produces the casting, machining requirements can be considered while reviewing the pattern, mould, datums and allowances. This provides one agreed delivery condition for the component.
Depending on the requirements, some operations may be carried out by machining partners. Before an order is placed, we confirm the work performed by METAL-KOLOR, the partner scope and responsibility for each stage.
Examples from the machining archive
The photographs show a component set up on a machining centre and a circular component inside a machine tool. They establish the machining context but do not specify the process, tolerance or material for a particular order.

FAQ
Before you send an enquiry
Answers about documentation, material and scope.
Do you only machine castings produced by METAL-KOLOR?
We review enquiries for customer-supplied components individually. Before production, we confirm the material, incoming condition, workholding and responsibility for the agreed scope.
Do you provide CNC machining?
Yes. We use conventional and CNC machines. Equipment selection and feasibility depend on the review of the specific component.
How should machined surfaces be identified?
Mark them on the current drawing and state datums, final dimensions, tolerances and surface texture when required. Also identify surfaces that are to remain as cast.
Is a 3D model sufficient without a drawing?
A 3D model describes geometry but often omits tolerances, surface texture, datums and acceptance criteria. We confirm the information needed before the order.
