Deep Hole Honing Machine For Cylinders

Siemens PLC control deep hole honing machine

 

 

1.1 Deep hole honing machining Range

Machining bore diameter: Φ25～Φ600 mm

Maximum machining depth of bore: 6 m

Maximum workpiece length: 6 m

 

1.2 Machine Functions and Purposes This machine is applied to finish honing of through holes and blind holes on cylindrical deep-hole parts such as hydraulic cylinders and air cylinders.It supports full-length honing and partial honing. During partial honing, it can correct the taper, ovality and local bore dimension errors of workpieces.The expansion and contraction of the honing head is controlled by a servo motor, realizing both constant-pressure feed and fixed-volume feed of the honing head.

 

1.3 Tool Oil Supply Mode External oil spraying and internal oil feeding.

 

1.4 Workpiece Clamping The workpiece is placed on two sets of V-type workpiece supports and fastened by pipe chain clamps.The V-type supports are manually adjustable to clamp workpieces with different diameters. 

1.5 Deep hole honing machine Main Structure of Machine Tool

 

1.5.1 Main Components It consists of bed, honing rod box, two sets of workpiece supports, honing rod bracket, gear and rack, cooling system, Siemens PLC control system, electric cabinet and other parts.

 

1.5.2 CNC Axes Axis

Z1: Longitudinal feed motion of the honing rod box (reciprocating movement of the tool). The servo motor drives the gear and rack mechanism through the reduction device. Axis

Z2: Controls the expansion and contraction of the tool. The servo motor drives the axial movement of the expanding ejector rod via the reduction mechanism.

 

1.5.3 Bed The bed is cast from high-quality cast iron and subjected to aging treatment to stabilize internal structure and dimensional accuracy and improve mechanical properties.Square ball linear guide rails are mounted on the bed for tool reciprocating movement, meeting the high-speed operation requirements of honing.A precisely machined and heat-treated rack is installed inside the bed for tool feed transmission to ensure stable operation.Oil receiving trays are arranged around the bed.

 

1.5.4 Honing Box It is used to drive tool rotation with stepless adjustable spindle speed.The motor drives the spindle to rotate through a gear reducer. All gears are precision ground with tooth surfaces treated by high-frequency quenching, featuring high strength, high hardness, excellent wear resistance and high fatigue limit, capable of bearing heavy alternating loads and impact loads.The spindle adopts combined support of cylindrical roller bearings and thrust ball bearings, which ensures high rotation accuracy and strong bearing capacity for axial and radial forces.Lubricating oil is adopted for gear and bearing lubrication to extend service life.

1.5.5 Workpiece Supports Two sets are equipped to support workpieces.It adopts a V-shaped structure. The two inclined sides of the V-block realize centering movement driven by forward and reverse lead screws. After the workpiece is placed on the supports, it is manually locked with pipe chains.Anti-slip backing plates are installed on the V-shaped inclined surfaces, which can effectively prevent workpiece rotation during machining.

1.5.6 Honing Rod Bracket It supports the honing rod during machining and measurement.A total of 3 sets are provided. One set is fixed on the machine bed, and the other two sets move along the linear guide rails of the bed.

 

1.5.7 Cooling System It supplies lubricating fluid for the tool.It is mainly composed of pumps, paper bag filter, magnetic roller filter, oil tank and other components.It is equipped with two oil supply modes: external oil spraying and internal oil feeding, which can be switched freely on the operation station.

1.5.8 Lubrication System The guide rail slides for the reciprocating motion of the honing rod box are automatically lubricated by an automatic lubrication station, which is equipped with a liquid level alarm function.Lubricating mechanical oil is filled inside the honing rod box for gears and bearings, and lubrication is realized by gear rotation.

 

1.5.9 Control System Adopt Siemens control system.Equipped with HMI touch screen, on which the reciprocating speed, spindle speed, tool feed rate and other parameters can be set.The operating station is mounted on the machine bed, and the operation panel can be manually rotated for convenient operation.

 

1.5.10 Oil Baffle Device It is installed on the linear guide rails of the workpiece bed. One set is arranged at the workpiece inlet and outlet respectively, and it can be manually moved along the full length of the workpiece bed.
