2M2120x6000mm Deep Hole Honing Machine

1. Machine Brief :

1.1 Machine processing capacity:

Hole diameter range :Φ40~Φ200mm

Max. Honing depth: 6000mm

Max. Workpiece length : 6000mm

1.2 Machine functions and application:

The machine is used for precision processing of various cylindrical workpieces with deep hole ,such as hydraulic cylinders and cylinders etc. .

It can do either integral honing or local honing ; When honing locally, the errors of taper, ellipse and local hole diameter 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, locked by the pipe pliers chain; V-shaped workpiece carriers could be adjusted by manual to clamp workpieces with different diameter .

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 , and so on .

1.5.2 CNC axis :

Z 1 axis: The longitudinal feeding movement of the honing box (honing head 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, control the centering movement of two inclined edges of V-shaped through the positive and negative screw .

The workpiece is placed on the carrier, locked with pipe pliers chain manually.

The cushion plate with anti-slip function is assembled on the inclined edge of the V-shaped wokpiece carrier, which can effectively prevent the workpiece from rotating during process.

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 Control 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.
