Cylinder Deep Hole Skiving Roller Burnishing Machine

Cylinder Deep hole skiving roller burnishing machine

 

1. Main Machine Performance & Function

Integrates boring, skiving and roller burnishing in one process.

Suitable for hydraulic cylinder bores, spindle holes, cylinder liners, cooling holes and other deep hole parts.

Machining accuracy: IT7~IT9; Inner surface roughness: Ra 0.1~0.4 μm.

Machine castings adopt box-type structure with FEA optimization, made of high-strength cast iron by resin sand casting. Multiple normalizing stress relief treatments ensure high rigidity and long-term precision stability.

2. Machining & Chip Removal Method

Processing Modes

Workpiece and tool rotate relatively with tool feeding

Workpiece rotates, tool feeds only without rotation

Workpiece stationary, tool rotates and feeds

Process & Chip Removal

Rough boring: Push boring with forward chip removal

Finish machining: Combined skiving + roller burnishing

All processes adopt oil feeder lubrication and forward chip removal to solve hole deviation and straightness problems of steel pipe deep holes.

3.Main Machine Structure

The machine consists of bed, headstock, servo clamping device, workpiece carrier, oil feeder, boring bar box, boring bar support, cooling system, hydraulic system and CNC system.

• Bed: Quenched rectangular guideway, split assembled structure; equipped with precision ball screw for Z1 axis and trapezoidal screw for Z2 axis.

• Headstock: Belt drive with stepless speed regulation; spindle with mechanical locking and electrical interlock function.
• Servo clamping: Applicable for rotating / static workpiece, self-centering by servo drive.

• Workpiece carrier: Height adjustable for auxiliary support of different workpiece outer diameters.

• Oil feeder: Core component for tool guiding, oil supply and workpiece positioning.

• Boring bar box: Precision ground gears with high-frequency quenching; independent circulating lubrication; spindle mechanical locking available.

• Boring bar bracket: Hook-type follow-up design for vibration absorption and automatic disengagement at set position.

• Cooling system: Three-stage filtration (coarse mesh → magnetic → fine cartridge filter), filtration accuracy 50 μm; equipped with pressure, flow, liquid level and temperature sensors.

• Hydraulic system: Provides power for gear shifting and automatic tool expansion/retraction.

 

• CNC System: Siemens 828D; main electrical components adopt famous brands with dustproof and air-conditioned electric cabinet.
