Contract Manufacturing
Precision CNC Machining in Türkiye
HEPTEKNIK manufactures precision machined components in Istanbul, Türkiye using CNC turning, CNC milling and Swiss-type machining for international OEM and industrial customers. Manufacturing is performed according to customer drawings, material requirements, dimensional requirements and applicable quality documentation.
Precision CNC Machining
A drawing-based precision manufacturing supplier
HEPTEKNIK manufactures to the customer's drawing and specification — not from a catalogue. Enquiries are reviewed for manufacturability before quotation, and approved parts move from first article into repeat series production under documented process control.
- Custom machined components produced to customer drawings and revisions
- Repeat production with stable, documented processes across order cycles
- OEM and Tier-supplier components for assemblies and sub-assemblies
- Manufacturing in Istanbul, Türkiye, with continuous operations since 1991
- International B2B manufacturing with technical communication in English
CNC Turning
Precision CNC turning
Turned components machined according to customer drawings and specifications for hydraulic, automotive and general engineering applications.
- Custom turned components produced to drawing, material and revision
- Prototype, pilot and series quantities under the same documented process
- Dimensional verification against the customer drawing before delivery
- Repeat production for OEM and Tier-supplier programmes
CNC Milling
3-axis, 4-axis and 4.5-axis CNC milling
Prismatic and complex-geometry parts machined on vertical machining centres in 3-axis, 4-axis and 4.5-axis configurations.
- 3-axis CNC machining
- 4-axis CNC machining
- 4.5-axis CNC machining
- Milled housings, bodies, brackets and prismatic components to drawing
- Series production through repeatable, documented processes
Swiss-Type CNC Machining
Sliding-head machining for small precision components
Swiss-type CNC machining for small precision turned components produced in medium and high volumes to customer drawings.
- Sliding-head machining for small precision components
- Precision turned components: pins, bushings, nozzles, threaded inserts
- Repeat production for medium and high-volume requirements
- Process and dimensional control maintained across production runs
Quality & Metrology
Precision is not only machined. It is measured.
In-house inspection supports dimensional verification and manufacturing quality throughout production. Characteristics are verified against the customer drawing, and inspection documentation is agreed per order.
- 3D CMM inspection
- Surface roughness measurement
- Contour measurement
- Optical measurement
- Dimensional inspection
- In-process inspection
- Final inspection
