C200-300 Lathe Technical Specification

1.1Structural Design-The machine adopts an integral 30° slant-bed structure, which not only conforms to ergonomic principles but also enhances rigidity through three key engineering measures：
Structural Pre-analysis：During the preliminary design phase, finite element analysis (FEA) is employed to simulate the mechanical behavior of key components such as the bed and guideways, precisely locating stress concentration zones under heavy cutting or high-speed motion conditions.
Deformation Suppression Control：Through optimization of the rib layout and wall thickness distribution, deformation induced by thermal and mechanical loads during machining is effectively minimized and strictly controlled.
Rigidity Assurance Logic:Through force chain analysis, cutting forces are evenly distributed across the entire bed structure, preventing localized stress overload and providing a stable foundation for high-precision machining.
1.2 Material and Process-The main body of the equipment is made of HT300 high-grade resin sand precision castings, naturally offering the following advantages:
Vibration and Noise Reduction:The graphite flakes within the cast iron can absorb cutting vibration energy, reducing chatter marks during machining.
Double Aging Process:Artificial aging rapidly relieves the residual stresses generated during casting cooling, preventing deformation in subsequent machining. Natural aging slowly releases the remaining residual stresses through temperature cycling, ultimately minimizing residual stress and ensuring equipment accuracy.
1.3 Core Configuration-The equipment comes standard with a 8-station servo turret and a precision hydraulic tailstock, enabling “multi-process composite machining” capability：
Machining Coverage Capability：Through the collaboration of the turret and tailstock, full-range machining can be achieved for workpieces from small shafts of φ5 mm to disc parts of φ300 mm. Typical applications include:
Shafts: One-pass forming of the automobile half shaft’s outer diameter, end face, and thread.
Disks: Compound machining of the flange’s inner hole, outer diameter, and grooving.
Complex Parts：Multi-process integrated manufacturing of hydraulic valve blocks.
