How do we start precision CNC machining parts service?

Zümre Makina is your CNC manufacturing partner for prototyping and mass production of CNC machined parts and CNC turned parts. Our concept is to make the best custom CNC machining parts from the beginning!

Free evaluation of precision CNC machining

Free assessment of precision CNC machining

Send your idea or 3D or CAD files and we'll get your project started right away for free evaluation. Our goal is to complete a quality and cost-effective plan for your parts within 30 minutes.

DFM analysis

DFM Feedback

Before we start producing custom machined components, we'll make a DFM analysis and develop a process control plan for all quality risk points. Our engineers will develop DFM risk-based program and then organize tools and cuttings to ensure the consistency of partial quality.

Quality control

Production and Quanlity control

During the precision machined parts production process, our QC engineers will conduct patrol inspections based on the engineering drawings, and follow certain test methods and frequencies to ensure that the quality meets the requirements of the drawings (appearance, dimensions, tolerances).

How does a CNC machine work?

CNC machining begins with a computer, where designers use CAD (Computer-aided Build) software to design a product. After that, the digital portion is translated into a format that a CNC machine can understand.

The CNC machine receives instructions in the form of “G-Code,” after which it can begin cutting.

To keep a block of material — known as the “workpiece” — in position, most CNC machines incorporate a “worktable” and a work holding device. Depending on the machine’s design, the worktable may or may not move.

The cutting tool makes contact with the workpiece as machining begins, cutting away layers of material. The tool and/or workpiece are moved and/or swiftly rotated in accordance with G-Code instructions, ensuring that cuts are performed in precisely the appropriate areas until the part is complete.

Mass production of custom cnc machined parts

How to choose materials and compare with national standards of various countries, so as to find precision cnc machining parts suppliers, or to facilitate communication during design?

We have prepared 40 kinds of material inventory in our partner companies warehouses to ensure that customers’ prototypes and small batch precision machining parts and mass production are completed within 24 hours.Some of our materials are approved by IMDS.
