CNC turning combines workpiece rotation with programmed cutting-tool movement. ENS Makina San reviews drawing-based CNC turning and contract machining enquiries in Sakarya. External and internal diameters, lengths, grooves and threads are assessed alongside material, quantity and inspection requirements. Machine suitability and process sequence are defined per part. Critical tolerances and verification methods are agreed before work rather than assumed.
What is reviewed before a CNC turning quotation?
Diameters, lengths, shoulders, grooves and threads are assessed together with workholding and tool access. For a replacement component, a worn sample’s dimensions are not automatically treated as the intended design.
State material, quantity, critical tolerances and secondary processes in one enquiry. If heat treatment or coating is needed, responsibility and sequence must be clarified rather than assumed.
First-part approval and repeat orders
Mention any first-part inspection or assembly trial before quotation. Repeat orders should refer to an agreed drawing number and revision. A sample and a newer drawing should not be assumed equivalent.
A CNC program defines machine movements. Acceptance criteria and inspection still need to match the part’s function. Size limits and achievable precision are confirmed after technical review.
What do we need for a quotation?
Share the application, drawing or sample information, material, quantity, critical dimensions and target date. Feasibility, tolerances and timing are assessed per project.

Components and order types for this service
Before we get started.
Which file should I send?+
Start with a current PDF drawing showing dimensions, tolerances and material. Mention the format of any available 3D model so file suitability can be discussed.
Can I enquire about a single part or small batch?+
Yes, state the quantity in your enquiry. Feasibility and setup requirements are assessed with geometry, material and inspection needs.
