HMS25 HMS35 HMS50 Deep Hole Honing Machine

HMS25 HMS35 HMS50 Deep Hole Honing Machine is specially used for finishing the inner hole surface of various hydraulic cylinders, cylinders and other cylindrical parts. After machining, the aperture accuracy of the parts reaches above it7, and the surface roughness reaches ra0.2-0.4 μ m.  The machine tool can also carry out local honing to correct the taper and ovality of parts.

The machine tool is equipped with Siemens 808d CNC system, linear rolling guide rail, Beijing CTB AC servo motor, and the grinding rod box adopts variable frequency motor with stepless speed regulation.

The honing process adopts constant pressure control, and the sand bar and workpiece always maintain constant pressure. For general cylindrical deep hole parts, the inner hole needs to be honed after boring; Cold drawn steel pipes with small allowance can be honed directly. Different honing oilstones are selected according to different materials, different physical characteristics and specific processing requirements.

The cooling system adopts three-stage filtration, and the filtration accuracy can reach 30 μ m.  The CNC system of machine tool integrates current detection, pressure display, etc.
