1.1 Machine processing capacity:

Hole diameter range :Φ10~Φ50mm

Max. Honing depth: 2000mm

Max. Workpiece length : 2000mm

1.2 Machine functions and application:

The machine is used for precision processing of various cylindrical workpieces with deep hole .

It can do either whole honing or local honing ; When honing locally, the errors of taper, ellipse and local diameter error can be corrected.

The expansion of honing head is controlled by servo motor, both constant pressure feeding and quantitative feeding could be realized .

1.3 Oil supply mode for honing head : External oil spray and internal oil feeding .

1.4 Workpiece clamping :

The workpiece is placed on two sets of V-shaped workpiece carriers, and pressed by the pressing plate .

1.5 Machine main structure:

1.5.1 Machine main parts

Machine bed, Honing box, 2sets workpiece carriers, Honing bar support rest, Rack

and pinion, Coolant system, DELTA PLC system, Electric cabinet ,full safety guard for machine main body and so on .

1.5.2 CNC axis :

reciprocating movement), the servo motor drives the rack and pinion mechanism through the reducing mechanism.

Z2 axis: Control the expansion of honing head, the servo motor drives the ejector pin to move axially through reducing mechanism .

1.5.3 Machine bed :

Cast by super casting iron HT300, with twice aging treatments to eliminate the internal stress , the structure and size are stabilized, and the mechanical properties are improved.

The linear guide rail is mounted on the machine bed , used for reciprocating movement of honing head, to meet the requirements of high speed during honing.

The inner side of machine bed is mounted with rack, use for the feeding transmission of honing head. The transmission of rack is stable after precision processing and heat treatment .

1.5.4 Honing box:

Used to drive the honing head to rotate, rotation speed is stepless .

The motor drives the spindle to rotate through the gear reducer, and the gear is ground precisely. The tooth surface of the gear is treated by high frequency quenching, and the hardness of the tooth surface is HRC48-52. In this way, the gear can obtain high strength, high hardness, high wear resistance and high fatigue limit, and can withstand large

alternating load and impact load.

The spindle is supported by a combination of cylindrical roller bearings and thrust ball bearings, has high accuracy and can withstand large axial and radial forces.

In order to improve the service life of gears and bearings, lubricating oil is used for lubrication.

1.5.5 Workpiece carrier:

2sets, used to support the workpiece .

V-shaped structure, adapt to the clamping of workpieces with different diameters by replacing pads of different thicknesses.

1.5.6 Honing bar support rest

Supporting honing bar in the process of honing and measuring.

2sets, one set is fixed on the machine bed, another set moves on the linear guide rail of machine bed .

1.5.7 Coolant system

Supply the lubricating liquid for honing head .

Mainly composed of pumps, paper filter, magnetic filer,oil tank etc. .

Provide external oil spray and internal oil feeding two oil supply methods for the honing head,which could be chosen on the operation panel .

1.5.8 Lubricating system

The slider of guide rail for reciprocating movement of honing box is lubricated automatically by automatic lubrication station, and liquid level alarm is provided on lubrication station.

The honing box is filled with lubricating oil ,the gears and bearings inside are lubricated by rotating the gears.

1.5.9 Control system :

DELTA PLC System.

Using human-machine interface touch screen, reciprocating speed, rotating speed and honing head feeding rate etc. can be set on it .

The operation station is assembled on the machine bed,the operation panel can be turned manually to facilitate the operation of the machine.
