Machine Tool Highlights
| Serial Number | Core Component | Process Standard and Requirement |
|---|---|---|
| 1 | Machine Bed Casting | HT300 integral casting + tempering + natural aging for > 90 days |
| 2 | Guide Rail Mounting Surface Processing Precision | Semi-finishing + precision grinding process, 1m front line ≤ 0.01mm, side line ≤ 0.005mm |
| 3 | Screw Pair | Randomly equipped with Yintai & 凯特 (Kate), ≥ Class C3, double-nut structure |
| 4 | Guide Rail Pair | Randomly equipped with Yintai & 凯特 (Kate), ≥ Class P, flange slider |
| 5 | Screw Bearing | Koyo, Class P4. Provided by Mingkeda: same as Beijing Jingdiao & Chuangshiji |
| 6 | Spindle Unit | Permanent magnet synchronous rear direct-drive integrated type, low mechanical load, low heat generation, high coaxiality. It can better achieve high speed, high precision and high rigidity. Moreover, the motor and bearing have a long service life and are easy to maintain. |
| 7 | Spindle Encoder | Using sine-cosine magnetic ring encoder, more stable operation and higher positioning accuracy |
| 8 | Spindle Bearing | Customized for fine machine tools: well-known domestic brand, Class P4 |
| 9 | Oil Cylinder & Chuck | Customized for fine machine tools: well-known domestic brand |
| 10 | Oil-cooled Hydraulic Station
Patent No.: 2025218556078 |
Working principle: On the basis of the ordinary hydraulic station, a 2700W refrigeration system is added to cool the hydraulic oil in the hydraulic station tank, and then deliver it to various pipes that need hydraulic oil, so as to realize their respective functions in a relatively low temperature state, effectively control the precision error caused by the thermal elongation of the machine tool, and delay the service life of relevant functional components. |
| 11 | Lubrication System | Special alloy steel gear pump + volumetric oil discharge, automatic pressure relief structure |
| 12 | Low-voltage Electrical Components | Schneider + Tiangzheng + Mean Well, ensure genuine products |
| 13 | Oil Circuit | Using smooth steel wire pipe with anti-burst pressure of 54MPa |
| 14 | Water Circuit | Using steel wire oil pipe with anti-burst pressure of 45MPa, standard filter |
| 15 | Internal Protection | SUS201-J1 grade plate, cutting precision < 0.05mm, suspended structure. When running in Z direction, the friction system is small, the machine tool vibration is small, and the motor load is small. It reduces the roughness of the outer circle surface and improves the linkage precision of Z direction and other axes. |
| 16 | External Protection | National standard 2.0 cold plate + outdoor powder spraying process + 304 door hinge. Heavy, anti-vibration and durable. |
| 17 | Control System | Tiesi A series controller + EtherCAT communication method, “fly-read fly-write” mechanism, realizing microsecond-level communication synchronization (optional) |
| 18 | Liquid-cooled Axial Motor | Power head motor: standard liquid-cooled;
Feed axis motor: X direction of the turret lathe can be equipped with liquid-cooled optionally. Advantages: effectively control motor temperature rise, reduce precision error caused by machine tool thermal elongation, and delay the service life of motor, screw and bearing. |
