1. Drawing and requirement review
The drawing, material specification, quantity and delivery expectations are reviewed by our engineering team.
Capability
CNC Milling Services in Turkey
HEPTEKNIK provides drawing-based CNC milling services for custom precision components in Istanbul, Turkey. Parts are machined according to customer drawings, material specifications and dimensional requirements.
With manufacturing experience since 1991, milling work is supported by process and fixture planning, in-house dimensional inspection and documented quality management systems.
Process
What Is CNC Milling?
In milling, the workpiece is held stationary on the machine table while rotating cutting tools remove material, which makes the process suitable for prismatic components rather than rotational ones.
- Flat and stepped faces, shoulders and contours
- Pockets, slots, grooves and profiled openings
- Drilled, bored, reamed and tapped holes
- Multi-sided features requiring repositioning or indexing
Milled parts usually start from bar, plate or block material. The machining sequence, workholding and the number of set-ups required are decided after reviewing the drawing, because they determine how the features on different faces relate to each other.
Capability levels
3-Axis, 4-Axis and 4.5-Axis Milling
HEPTEKNIK operates vertical machining centres in 3-axis, 4-axis and 4.5-axis configurations.
- 3-axis milling for prismatic components whose features are machined from a single main orientation
- 4-axis milling with a rotary axis, used for indexed or continuous positioning around the part
- 4.5-axis milling for components that require an additional positioning axis for angled or multi-side features
The manufacturing route for each component is selected according to drawing geometry, material, dimensional requirements and quantity. Suitability for our 3-axis, 4-axis and 4.5-axis milling configurations is confirmed during technical review before quotation.
Component types
Custom CNC Milled Components
Typical milled component families produced at HEPTEKNIK include:
- Plates and blocks
- Housings
- Brackets
- Flanged components
- Manifold-style components
- Machine components
- Fixtures and interfaces
- Drawing-specific milled metal parts
These are examples only, not catalogue products. Every component is manufactured to the customer's own drawing and technical specification.
Materials
Materials and Manufacturing Requirements
Materials are processed according to the customer drawing and approved technical specification.
Stainless steels, carbon and heat-treatable steels, brass and aluminium alloys are among the material families regularly machined at HEPTEKNIK. Machinability, heat-treatment condition, surface requirements and any secondary processes are reviewed before production; 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, the number of faces to be machined and the required operations are assessed against our milling configurations.3. Process and fixture planning
The machining sequence, workholding and fixturing are planned so that features on different faces are produced consistently.4. Inspection planning and first-piece approval where required
The dimensional checks are planned with the process, and a first piece is produced and approved where the customer or the part requires it.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 for CNC Milled Parts
Inspection is planned together with the machining process rather than added at the end.
- In-process dimensional control 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
Milled 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 technical and customer requirements can be met
Applicability is assessed per project. Sector-specific approvals and product requirements are reviewed with the customer before any commitment.
Process selection
CNC Milling and Other Machining Processes
Machining processes are selected according to the part rather than the other way round:
- CNC milling is used for prismatic parts and multi-face features such as pockets, slots and hole patterns
- CNC turning is used for rotational parts whose main features are produced while the workpiece rotates
- Swiss-type sliding-head machining is used for suitable small-diameter turned components in the verified Ø1–Ø32 mm range
Many components combine these processes, and the sequence is planned during manufacturability review.

FAQ
Frequently Asked Questions
- Do you provide CNC milling services in Turkey?
- Yes. HEPTEKNIK provides CNC milling services from its facility in the İkitelli Organized Industrial Zone, Istanbul, Turkey, and has been manufacturing machined components since 1991.
- What is the difference between 3-axis, 4-axis and 4.5-axis milling?
- 3-axis milling machines features from a single main orientation. 4-axis milling adds a rotary axis so the part can be indexed or positioned around that axis. 4.5-axis milling provides an additional positioning axis for angled or multi-side features. HEPTEKNIK selects the appropriate configuration after reviewing the component geometry and dimensional requirements.
- Can HEPTEKNIK manufacture parts from customer 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 milling 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.
