HC35X3M

The HC35X3M CNC deep-hole honing machine supports constant-pressure honing with simple and convenient operation. Adopting a workpiece-fixed structural design, the equipment realizes honing processing through the rotation and reciprocating linear motion of the honing head. It is specially designed for honing and polishing cylindrical deep-hole workpieces, widely applicable to precision tubular parts such as hydraulic cylinders and pneumatic cylinders.
The machine achieves a machining accuracy of IT6–IT7 or higher for bore diameters, with the surface roughness reaching Ra 0.2–Ra 0.4 after polishing. The localized honing function effectively corrects workpiece machining errors including taper, ovality and partial aperture deviation. It can directly perform honing on cold-drawn steel tubes, serving as an ideal high-precision and high-efficiency deep-hole finishing equipment.
Equipped with a professional PLC control system, the machine features stable commutation and flexible speed regulation during operation. It ensures consistent bore dimensional accuracy while greatly reducing labor intensity. The system stably controls the expansion dimension of the honing head throughout the honing process, guaranteeing uniform bore diameter precision and significantly improving deep-hole honing efficiency.
The honing head adopts a servo motor matched with a reducer for constant-pressure expansion, delivering stable and constant honing force from the abrasive strips to ensure excellent roundness and cylindricity of workpieces. The honing rod is equipped with universal joints at both ends, which effectively guarantee the straightness of machining and overall equipment stability. The honing pressure is adjustable to meet diverse processing requirements. The machine’s machining diameter range is Φ50–Φ350 mm.
Featuring easy operation, high production efficiency and superior economic benefits, this equipment is adaptable to both mass production and single-piece & small-batch processing scenarios, making it an optimal choice for deep-hole precision finishing.
