2M2120Deep Hole Honing Machine 2000mm Max Honing Depth

Inner bore defects such as taper and ovality often appear after boring for hydraulic cylinder tubular workpieces and extra manual correction work is required. This 2M2120x2000mm deep hole honing machine supports both full length honing and local honing. Servo controlled honing head expansion enables constant pressure feeding and quantitative feeding modes. It achieves roundness tolerance below 0.01mm and surface roughness Ra0.2‑0.4μm. This machine is well suited for precision inner hole finishing of hydraulic cylinders and other cylindrical deep hole components in general heavy industry.

Core Advantages

The machine bed is made of HT300 high strength cast iron. It goes through normalization treatment and two times aging treatments to eliminate internal casting stress and stabilize overall structure dimension.

High precision linear guide rails are mounted for high speed reciprocating movement of honing box. Precision heat treated rack is fitted inside the bed to deliver stable feeding transmission.

The honing box adopts frequency conversion motor driving gearbox unit. Gears are precision ground and high frequency quenched to reach HRC48‑52 tooth surface hardness. Combined cylindrical roller and thrust ball bearing configuration for spindle can sustain large axial and radial cutting load. Internal splash lubrication extends service life of gears and bearings.

Two sets of V‑shape workpiece carriers are equipped. V‑blocks realize centering adjustment through positive and negative screw mechanism. Workpieces are fixed by pipe clamp chain. Anti‑slip cushion plates on V‑block surface prevent workpiece rotation during honing process. One fixed and one movable honing bar support rests are arranged. They hold honing bar steadily during reciprocating stroke and effectively reduce tool vibration. The coolant system integrates paper tape filter and magnetic roller filter to reach 20‑micron filtration accuracy. It provides external oil spray lubrication for honing process and keeps honing oil clean to avoid workpiece scratch. Automatic lubrication station supplies timing quantitative lubrication for guide rail sliders with low liquid level alarm function. DELTA PLC plus rotatable touch screen HMI allows operators to set reciprocating speed, spindle speed and honing head feeding parameters conveniently. Multiple safety protection functions are built inside the control system.

Ideal Workpieces & Pain Points Solved

Suitable workpieces include hydraulic cylinder barrels and various cylindrical deep hole tubular parts.

Common production difficulties this machine solves. Taper ovality and local aperture deviation on inner bore after previous boring procedure. Unstable inner surface roughness caused by honing bar vibration. Fine metal chips contaminating honing oil and scratching workpiece inner wall. Complex parameter adjustment for different batches of tubular parts. Additional manual repair work for local inner‑hole defects.
