Structure
The main iron castings are used advanced material, and through annoaling. eliminate stress.to ensure the high precision, high rigidity. and prolong the life of the machine.
Slide
Grinding machine and double v slide adhesive wear resistant resin TURCITE-B (Teflon), andwith the precision scraping. not only the sliding smoothly and wearresistance, the most suitablefor torm grinding
Spindle
Using single type integrated design of spindie directly and P4 grade ultra precision bevel rollerbearing. rotating in high speed, low noise. no vibration, large torque, suitable for heavy cuttingand all kinds of form grinding.
Automatic lubrication system
Adopting circulation type automatic lubrication system, when the spindle starts. lubricatingoil automatic cycle provides
lubrication for each screw and slide, can greatly reduce the slidewear. A mirror can watch case oil lubricating machine column above.The SGA3063,SGA40100 Hydraulic Saddle Moving Surface Grinder machine with pleasing appearance and well designed structure, the machine is an indeed precision grind equipment for metal working.
The well designed structure have good rigidity and keep the machine with high accuracy.
Well designed and carefully assembled Hydraulic unit make the table moves smoothly. The oil temperature increase low after long working.
