Overview of machine tool：
The machine tool is a two axle CNC internal grinding machine tool. It adopts German SIEMENS CNC system, liquid crystal display, and automatic measuring instrument on-line, to realize automatic grinding cycle and ensure the precision of processing size. The grinding wheel feeding and work table moving are driven by AC servo motors through ball screws. The grinding wheel adopts high precision cross steel guide rail to ensure the accuracy, sensitivity and rigidity of the machine when it moves. The plastic guide rail is adopted in the worktable to improve its aseismic and sensitivity.The head frame motor adopts AC frequency conversion device to achieve stepless speed regulation.
The tail frame sleeve has the function of hydraulic expansion.
The machine tool is equipped with automatic timing and quantitative lubrication to ensure the lubrication of the guide rail and the screw rod. The machine is equipped with protective cover to ensure safe operation.An independent electrical cabinet, oil tank and water tank are equipped to the machine tool.

Structural features of machine tool：
The body is an integral structure, the inner stiffener is arranged in a box type, and the high strength and low alloy cast iron casting is used, and a reasonable aging treatment has been made. It has a high overall rigidity and strength. It meets the requirements of high efficiency and high precision equipment for foundation parts.
Grinding frame and feeding system：
The spindle system of the grinding wheel frame is driven by a ball screw. The guide rail of the grinding wheel adopts high precision cross steel guide.
Wortable mobile mechanism：
The worktable adopts a double-layer structure to facilitate the adjustment of the accuracy, the rotating working table can grind the conical surface parts.
The moving mechanism of the worktable adopts the AC servo motor to directly drive the ball screw to control the movement of the worktable. The guide rail of the worktable is a sliding slide guide.
Head frame ：
The head frame motor drives the dial work piece to rotate through the pulley, and the speed is controlled by the AC frequency conversion, and is connected with the system to realize the automatic switching of the speed in the grinding process. The Top frame of the head frame is Morse No.5.
It is placed on the work table and is opposite to the head frame, and the main shaft of the sleeve is driven by hydraulic pressure. The stroke is less than 40mm. The top of the tail frame is Morse No. 5.
Adopting the front dressing, the diamond pen is adjusted by two axes of X and Z axis to realize the dressing of the outer circle, the end face and the arc of the grinding wheel.
The measuring instrument of Accretech (Japan) is used to do the axial orientation of the work piece and measure it online. It is connected with the CNC system and completes the automatic circulation of workpiece grinding.
It adopts independent cooling design and magnetic filter cooling water tank to further ensure the grinding quality.
According to the characteristics of continuous production, it is equipped with totally enclosed protection to prevent splashing of coolant and ensure clean environment and healthy operation of operators.
The machine tool adopts SIEMENS CNC system and LCD dispaly. The machine cabinet and machine tool protection device are integrated, and equipped with a dehumidification and cooling device. The sealing performance is good, and the main electrical components are Schneider products.
