In modern high-tech manufacturing, the production of complex parts for the defense industry, aerospace sector, instrumentation, and die and mold manufacturing requires strict accuracy grades (IT5–IT6) and micron-level tolerances. Traditional mechanical machines cannot ensure stable repeatability under such conditions, as elastic deformation, thermal fluctuations, and linear wear of mechanisms lead to defects.
MACHENTECH, as the official representative of leading global equipment manufacturers in Ukraine since 2012, offers a comprehensive range of high-precision CNC equipment. We supply precision milling centers, EDM systems, honing machines, and coordinate measuring machines that make it possible to achieve positioning accuracy within ±1–2 µm and surface roughness Ra < 0.1 µm.
Technological areas of high-precision equipment in the met.ua catalog
The high-precision machining category combines technological solutions designed for maximum dynamics, backlash-free motion transmission, and direct thermal control:
1. High-speed 5-axis CNC milling machining centers (HSC)
High-speed milling with linear motors makes it possible to machine hardened steels, titanium, and aluminum alloys in a single setup:
- Direct linear drive: The absence of ball screws and gearboxes eliminates backlash and friction, providing acceleration and rapid traverse speeds up to 60 m/min.
- High-frequency spindles: Speeds from 36,000 to 42,000 rpm with HSK-E40 / HSK-E50 tapers ensure clean micromilling without burr formation.
- Integrated thermal control: Active liquid thermal stabilization of the machine bed and spindle compensates for dimensional thermal drift during long continuous milling cycles.
2. Precision electrical discharge machining equipment (EDM)
Electrical discharge machining with pulsed discharges is indispensable for producing tooling, dies, punches, and deep slots in hard alloys:
- CNC wire EDM machines: Provide ultra-precise cutting of hardened metal with positioning repeatability up to ±1 µm.
- Die-sinking EDM machines: Make it possible to create complex blind cavities and mirror-like surface finish without further manual polishing.
- EDM super drills: Used for high-speed drilling of start holes for wire EDM and cooling microchannels from 0.15 mm in diameter.
3. Machines for precision hole honing
These machines create precise geometry, including cylindricity and roundness, as well as the required microrelief pattern in engine cylinders, hydraulic components, and barrels:
- Eliminate ovality and taper after preliminary boring.
- Ensure stable accuracy for diameters from micro-sized parts to large components over 2–3 meters long.
4. Coordinate measuring machines (CMMs) and metrology
Laboratory and shop-floor quality control that integrates directly into the production ecosystem for automatic correction of CNC machine axis offsets.

Frequently asked questions about high-precision CNC equipment
How can the stated passport accuracy of ±2–5 µm be achieved in production?
To achieve passport-level micron accuracy, a set of conditions must be maintained: spindle warm-up before operation, workshop thermal stabilization, use of balanced tooling (class G 2.5 / 25,000–30,000 rpm), and high-quality coolants or synthetic dielectrics.
What is included in the commissioning cost of a high-precision machine?
Commissioning is performed turnkey. The cost includes machine bed leveling, axis calibration, peripheral equipment connection, CNC setup, and production of a control part according to the customer’s drawing.
Is it possible to test the equipment before purchase?
Yes, we invite engineers and company managers to our demonstration centers. You can send your drawings, and our technologists will develop the optimal machining process and demonstrate the machine operation directly on your materials.
