Machine functions:

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 whole 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 .

Oil supply mode for honing head : External oil spray , Internal oil supply.

Deep hole honing machine popular models avalaible:(until honing to 2m diameter and 25m long)

Machine main structure:

Machine main parts include：Machine bed, Honing box, 2set workpiece carriers, Honing bar support rest, Rack and pinion,Coolant system,SIEMENS PLC control system, Electric cabinet , and so on .

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 .

Machine bed :

Cast  by super casting iron  HT300, after twice aging treatments, the  internal stress  is eliminated, the structure and size are stabilized, and the mechanical properties are improved. 

The  linear  guide  rail  (as  shown  below)  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 .

                                                    Linear guide rail

Honing box:

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

The variable frequency 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. The spindle 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.

Workpiece carrier:

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 clamp 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  in process of honing.

Honing bar support rest

Supporting honing bar in the process of honing and measuring.

2 sets, 1set is fixed on the machine bed, another set moves on the linear guide rail of machine bed .

Coolant system

Supply the lubricating liquid for honing head .

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

Could provide external and internal two oil supply method for the honing head, it can be exchanged on the operation panel .

Lubricating system

The  slider  of  guide   rail  for   reciprocating   movement  of   honing   box  is   lubricated automatically through  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 the rotation of the gears.

Control system :

SIEMNES PLC control. An HMI touchscreen is adopted, allowing the reciprocating speed, rotation speed, and tool feed rate to be set directly on the screen. The operator station is mounted on the machine bed, and the operation panel can be manually rotated for convenient machine operation.

Electrical box:

Schneider low voltage electrical components:

Application industry: hydraulic industry,construction vehicle industry,aviation industry,machinery industry,coal mine machinery,moulds and dies industry,energy industry,water dam,car& engine industry.
