The entire machine is ergonomically designed for user-friendly operation. The machine bed is manufactured from high quality cast iron, specially heat treated and precision machined to ensure deformation-free perfromance, year after year.
All slideways are lubricated by the static pressure automatic lubrication system, thereby providing extremely smooth movement and maximum wear resistance.
All the grinding motions – from rough grinding, dressing, finish grinding to spark out – are fully automatically operated. This provides high accuracy, convenient operation and greatly upgrades production. Also, it is excellent for mass production as well as small quantity, flexible workpiece grinding.
The workhead spindle runs on a high precision roller bearing featuring high accuracy, high rigidity and silent running. The workhead can be swiveled at 8° forward and 7° backward, allowing for grinding tapered workpieces.
Precision ball screws combined with servomotor driver provide variable feed speed changes.
The servomotor features compact construction, superior torque output, fast speed response, high accuracy and stability.
Suitable for grinding internal straight hole, end face, internal end face, internal slot, internal chamfering angle, internal circle angle, internal taper and internal taper and internal step, etc.
To meet mass production requirements. automatic loading and unloading equipment is availiable to provide a fully automatic operation.
