Application:The machine is mainly applied to the piston rod polishing before and after polishing process.
Polishing method :through dry polishing 
Equipment Composition: The machine is composed of a bed, a polishing head and workpiece conveying device, workpiece automatic feeding rack , automatic unloading device , unloading material frame.

Feature: 
★With high degree of automation, high efficiency, high processing precision characteristics. After polishing the roughness can reach Ra0.2-0.85
★Workpiece automatic up and down material, electric control polishing head pressure adjustment.
★Roller spacing electric control adjustment.
★Color touch screen is used as the main man-machine control interface
★With production management functions
★Machine action interlock protection
★Alarm diagnosis function: machine fault content on screen display. Maintenance personnel to be able to timely and accurate troubleshooting.
★German SIEMENS 7 inch color touch screen, SIEMENS inverter, SIEMENS PLC.
★Taiwan silver ball screw
★Matching features: automatic adjustment of grinding current. In a certain range, the use of PID control, automatic adjustment of the grinding current value, so that more convenient processing.

Polishing head:

There are 6 set of polishing heads that the first 4 sets are equipped with multi-leaf wheels with multi-granularity, the fifth set is linen wheels and the sixth set is cotton wheels. Every polishing head is equipped with a polishing ampere meter so that polishing pressure of polishing wheels can be seen visually and is easier to adjust. Polishing wheels electrically control vertical movement by reduction gears and ball screws.

  

Man-machine interface:

Machining conditions are reflected by animation which is vivid and easy to operate. Preset processing quantities. When processing amount is reached, the machine halts automatically. With database, it can call out and check machining conditions at any time to statistically manage.

Polishing ampere meter:

Every polishing head is equipped with a polishing ampere meter to visually see polishing pressure. And adjust polishing pressure of polishing wheels according to polishing voltaic pressure.

Workpiece automatic loading frame:Through inductive switches, automatically grab piston rod on loading frame one by one to workpiece conveyor.

Handing equipment for workpiece automatic machine unloading: After polishing piston rod, induce whether piston rod is in place through photoelectric sensor. When it is in place, automatically unload on unloading frame which is convenient and safe.

Workpiece conveyor:On both loading and unloading sides, two reduction gears drive idler wheels on one side and the speed can be adjusted. The angle of inclination of idler wheels on the other side can also be adjusted. Interval between idler wheels can be electrically controlled by buttons.
