This machine tool is the common internal grinding machine which is applicable for single piece small batch production to grind the cylindrical or conical inner hole (through hole or blind hole) on various mechanical spare parts.

I. Structural features and performance of the machine tool

1. Layout of the machine tool adopts the following grinding form; fixed by headstock, the abrasive wheel performs horizontal feed motion and the working label performs vertical reciprocating motion;

2. Feed of the machine tool and dressing compensation of abrasive wheel is performed by two mechanisms without mutual interference. There’s no need to adjust the machine tool again after the new abrasive wheel is replaced;

3. The feed system has certain grinding function to control the size of work piece; both manual and hydraulic feed is available for the abrasive wheel;

4. The quick jump mechanism of the abrasive wheel set for the machine tool. Manual tool setting is unnecessary after measuring or dressing upon abrasive wheel retracting;

5. The motion of the working table is of hydraulic driving. Stepless regulation is available for motion speed. The vertical inching mechanism is set to adapt to the grinding face of internal grinding tools;

6. The plane is set for machine tool body which creates condition for installing central frame of the long work piece;

7. High speed abrasive wheel of 1800r/min is optional (special ordering) to adapt to grinding of the hole of 20-50mm.
