1. Drawing and requirement review
The drawing, material specification, quantity and delivery expectations are reviewed by our engineering team.
Capability
CNC Turning Services in Turkey
HEPTEKNIK provides drawing-based CNC turning services for custom precision components in Istanbul, Turkey. Parts are manufactured according to customer drawings, material specifications and dimensional requirements.
With manufacturing experience since 1991, we support recurring industrial production through process planning, dimensional inspection and documented quality management systems.
Process
What Is CNC Turning?
In turning, the workpiece rotates while the cutting tool is guided along it, so the process creates cylindrical and rotational features directly from the rotating stock.
- External and internal diameters, faces and shoulders
- Grooves, chamfers, radii and other rotational features
- Threads produced according to the drawing specification
- Additional milling, drilling or secondary operations where the drawing requires them
The correct manufacturing route is selected after reviewing part geometry, material, dimensional requirements and quantity. Some components are completed on turning centres alone, while others are planned as a combined turning and machining-centre sequence.
Component types
Precision Turned Components We Manufacture
Typical turned component families produced at HEPTEKNIK include:
- Shafts and pins
- Bushings and sleeves
- Adaptors and connectors
- Threaded components
- Hydraulic fitting bodies
- Spacers
- Flanged and rotational components
- Customer-specific turned metal parts
These are examples only. Production is always based on the customer drawing and technical specification rather than a fixed catalogue range.
Custom production
Custom CNC Turned Components
HEPTEKNIK does not sell a generic catalogue from this page. Each customer-specific component is evaluated before quotation according to:
- Part geometry
- Material specification
- Dimensional and surface requirements
- Required quantity
- Inspection requirements
- Applicable secondary processes
This review determines whether the component is suitable for our turning capability, which operations are needed and how the part will be inspected during and after production.
Process selection
CNC Turning and Swiss-Type Machining
Conventional CNC turning is evaluated for rotational parts according to their geometry, workholding needs and required operations.
Swiss-type sliding-head machining is separately available for suitable small-diameter components in the verified Ø1–Ø32 mm range. Where a drawing falls into that category, it is reviewed against our sliding-head capability instead.
Materials
Materials and Manufacturing Requirements
Materials are processed according to the customer drawing and approved technical specification.
Machinability, heat-treatment condition, surface requirements and secondary processes are reviewed before production. Stainless steels, carbon and heat-treatable steels, brass and aluminium alloys are among the material families regularly machined at HEPTEKNIK; where a specification requires a treatment outside our machining scope, this is identified during review and agreed with the customer.
Workflow
From Technical Drawing to Series Production
2. Manufacturability evaluation
Geometry, workholding, required operations and secondary processes are assessed against our turning capability.3. Process and inspection planning
The machining sequence, tooling and the dimensional checks required during and after production are planned.4. Sample or first-piece approval where required
When the customer or the part requires it, a sample or first piece is produced and approved before series release.5. Recurring production
Approved parts are produced to agreed schedules with in-process dimensional controls.6. Final inspection and shipment
Components are inspected before packing, with inspection records prepared according to customer requirements.
Quality
Quality Control and Dimensional Inspection
Inspection is planned together with the machining process rather than added at the end.
- In-process dimensional controls during production
- Final inspection before packing and shipment
- CMM / 3D measurement where appropriate to the part
- Inspection records according to customer requirements
- ISO 9001, ISO 14001 and ISO 45001 management systems
Applications
Industries and Applications
Turned components are manufactured for a range of industrial applications, subject to review of the customer's requirements:
- Hydraulics
- Automotive and mobility applications
- Industrial machinery
- Construction and agricultural equipment
- Defense and aerospace applications where customer and technical requirements can be met
Applicability is assessed per project. Sector-specific approvals and product requirements are reviewed with the customer before any commitment.

FAQ
Frequently Asked Questions
- Do you provide CNC turning services in Turkey?
- Yes. HEPTEKNIK provides CNC turning services from its facility in the İkitelli Organized Industrial Zone, Istanbul, Turkey, and has been manufacturing machined components since 1991.
- Can HEPTEKNIK manufacture parts from our technical drawings?
- Yes. Production is drawing-based: components are manufactured to the geometry, materials, dimensional and surface requirements defined in the customer's technical drawing and specification documents.
- What information is required for a CNC turning quotation?
- We need the technical drawing, the material specification, the required quantity and your delivery expectations. Inspection requirements and any applicable secondary processes should also be stated so they can be planned before quotation.
- What is the difference between CNC turning and Swiss-type machining?
- Conventional CNC turning is evaluated for rotational parts according to geometry, workholding needs and the operations required. Swiss-type sliding-head machining is a separate capability for suitable small-diameter components in the Ø1–Ø32 mm range.
