Application Scenario
1. Automobile manufacturing industry
Final finishing of precision holes such as engine cylinder block, cylinder liner, crankshaft hole, connecting rod hole, etc. Hole machining of transmission housing, hydraulic valve body, etc.
2. Aerospace Industry
High-precision deep hole processing for aircraft landing gear hydraulic cylinders, fuel nozzles, etc. Honing of turbine blade cooling holes and the inner wall of engine combustion chambers.
3. Energy and heavy machinery
Precision finishing of hydraulic cylinders, pump bodies, and valve cavities. Honing of main shaft bearing holes of wind turbines and pipelines of nuclear power equipment.
4. Molds and general machinery
Dimension correction and surface polishing of ejector holes and guide holes of injection molds.
Batch processing of high-precision bearing seat holes and gearbox holes.
Processing object
1. Material type
1) Metal material: cast iron, carbon steel, alloy steel, stainless steel, aluminum alloy, copper alloy, etc.
2) Special material: ceramic coating surface, carbide inner hole (special honing tool required).
2. Hole type and specification
1) Shape: through hole, blind hole, step hole, special-shaped hole (such as tapered hole).
2) Size range: diameter is usually Φ5mm to Φ500mm, depth can reach several meters (special configuration required).
3) Accuracy requirements:
roundness ≤2μm,
cylindricity ≤3μm,
surface roughness: Ra 0.1~0.4μm.
Processing advantage
1. Ultra-high machining accuracy
1) Through the floating fixture and precision spindle system, micron-level shape correction (such as eliminating ellipticity and taper) can be achieved.
2) The aperture size tolerance (IT6~IT7 level) and surface quality can be controlled simultaneously, reducing the subsequent grinding or polishing process.
2. High efficiency and adaptability
1) Multi-axis synchronous processing: Some models support multi-station honing, which is suitable for mass production.
2) Complex hole processing: The reciprocating speed and pressure of the honing head can be adjusted through programming to meet the processing requirements of different apertures and depths.
3. Excellent surface quality
1) The unique mesh texture structure of honing can improve lubricity and extend the service life of the workpiece (such as the wear resistance of hydraulic cylinders).
2) Avoid burns or microcracks that may be caused by traditional grinding, especially suitable for parts with high fatigue strength requirements.
