03 / HONING
Deep-bore surface finishing across φ40–φ500 mm honing diameters, IT7–IT8 accuracy, and Ra 0.4–0.2 μm surface roughness.
The HM50×3000 heavy-duty deep-hole honing machine holds the workpiece stationary while the honing head rotates and reciprocates. A 22 kW variable-frequency spindle and PLC automatic cycle provide precision honing and polishing.

The honing rod box and slide combine a 22 kW variable-frequency spindle, rack-and-pinion reciprocation, and automatically lubricated linear guideways.
RECIPROCATING HONING UNIT
A 22 kW variable-frequency motor directly drives the honing rod spindle with stepless speed control. The rotating honing head reciprocates with the slide for constant-torque honing.

FEED GUIDEWAY
The slide runs on automatically lubricated linear guideways. A servo motor drives its rack-and-pinion mechanism for smooth reciprocation.

SYSTEM 02
V-block positioning and chain clamping hold the workpiece while the honing rod support guides the tool and the honing head expands its abrasive stones.
WORKPIECE SUPPORT
A V-shaped fixture locates the workpiece and a chain clamps it in place. It accommodates workpiece outside diameters of φ80–φ600 mm; the slide moves along the guideways to suit different lengths.
HONING ROD SUPPORT
The honing rod uses a universal joint. Its support and guidance help maintain straightness and machine stability when machining long bores.

SYSTEM 03
A PLC controls the automatic cycle, while a 10-inch touchscreen displays reciprocating speed. Smooth reversal and easy speed adjustment support deep-hole honing.
CONTROL PANEL
The 10-inch touchscreen displays reciprocating speed. Together with the PLC automatic cycle, the panel enables smooth reversal and convenient speed adjustment.
ELECTRICAL SYSTEM
The control and drive cabinets house the PLC, drives, and electrical components for reciprocation, honing-head expansion and retraction, and automatic machining cycles.

FEATURED MODEL
The HM50×3000 holds cylindrical deep-hole workpieces stationary while the honing head rotates and reciprocates for bore honing and polishing.
