DHH-35, DHH-50 CNC high efficiency deephole honing machine is the equipment suitable for honing and burnishing cylindrical deephole parts such as various precision hydraulic oil cylinders and cylinders etc. The machine is specialized in honing and burnishing step holes and the accuracy of hole diameter can be up to or over IT8-IT9, while the surface roughness is Ra 02.-0.4µm.It can also be used to repair and maintain taper and ellipticity of machined workpieces under the cooperation of partial honing. The cold drawn steel tube can directly be honed powerfully.
This deephole honing machine is the ideal equipments for deephole machining with high precision and high efficiency. The machine is mated with SIEMENS or FANUC or other CNC system. AC servo motor. The honing box adopts stepless speed regulation, and Germany ATLANTA high accuracy racks. The gears are installed to realize the reciprocation of honing head, thus the honing position is under control precisely. Mated with linear guideway , it possesses long service life and high accuracy. The honing head adopts hydraulic constant pressure expanding system, sand blades always maintain constant pressure to sure the roundness and cylinder of workpieces. The honing pressure can be regulated with reference to the requirement. The pressure is under control which can realize the rough and finish honing on the control panel.
