C400K Classic CNC Slant-bed Lathe

Reliable Brother C400K Classic CNC Slant-bed Lathe (Cost-effective Choice)

The Reliable Brother C400K is a slant-bed CNC lathe with high precision and quality and good economy.

Technology Upgrade Highlights:

  • 1. High-precision servo-driven tool holder

An international horizontal hydraulic servo turret tool holder (domestic preferred/imported configuration) is selected to achieve ±0.005mm positioning accuracy, tool change response time <0.8s, and structural deformation under heavy cutting conditions ≤0.01mm/m (ISO 10791-2 standard verification).

  • 2. Precision linear guide assembly

Equipped with a Taiwan brand linear guide, friction coefficient <0.002, temperature rise ≤3℃ at high speed feeding (24m/min), ensuring the stability of machining accuracy (continuous 72 hours cutting test error <5μm).

  • 3. Fully enclosed protection system

Integrated sheet metal protection (3mm cold-rolled steel plate), operating noise ≤ 75dB (A), three-proof (waterproof/oilproof/dustproof) grade up to IP54, safety interlocking mechanism through the CE Machinery Directive certification.

  • 4. Industrial-grade sealed electronic control systemThe protection level of the electric cabinet is IP55, equipped with an independent refrigeration unit as standard (temperature control precision ±1℃), ensuring the trouble-free operation of the numerical control system under the extreme environment of 45℃/95%RH for ≥5000 hours (IEC 60068-2-30 test).
  • 5. Intelligent chip removal system

Modular chain plate chip removal device (optional), chip removal efficiency ≥100kg/h, with overload automatic reversal protection, blocking material alarm function, compact design saves 20% of occupied space (compared with traditional structure).

Core technology upgrade analysis:

  1. High rigidity spindle system

By adopting a P4 grade double-row precision angular contact bearing set, the axial rigidity is increased by 30%, and the precision attenuation is small under heavy cutting conditions.

2.45°Integrated slant bed structure

After three artificial aging treatments (450℃×6h annealing process), the bed has excellent torsional rigidity and stable batch processing.

  1. Lightweight enhanced structure

Topology-optimised round cavity casting achieves a 33% increase in flexural rigidity.

  1. Intelligent thermal management system

Hydrodynamically optimised heat dissipation duct (ANSYS CFX simulation), spindle box temperature rise is controlled within Δ15℃ (ISO 230-3 test conditions), and the temperature drift is <8μm for 8 hours of continuous operation.

  1. Precision motion components

The integral drag plate adopts standard processing, and the cumulative error of assembly is <±0.005mm (detected by laser interferometer), which meets the requirement of dynamic precision.
