Wheel Head Moving Cylindrical Grinder is a precision machine tool used to process the outer surface of cylindrical workpieces. The main feature of this grinder is that the grinding wheel frame can move along the bed rails. During the processing, the workpiece is usually supported and rotated by the headstock and tailstock, and the grinding wheel frame rotates at high speed with the grinding wheel and approaches the workpiece. The material on the surface of the workpiece is removed through the relative movement of the grinding wheel and the workpiece, thereby realizing the grinding of the outer circle of the workpiece.

Compared with ordinary cylindrical grinders, the advantages of wheel head moving cylindrical grinder are as follows:
1. Higher processing accuracy
(1) High grinding wheel frame movement accuracy: The grinding wheel frame of the mobile grinding wheel frame external cylindrical grinder can move accurately, which can achieve more precise feed control. During the processing, micro-adjustments can be made according to the different requirements of the workpiece to ensure processing accuracy. For example, for some high-precision shaft parts, the shape and position tolerances such as cylindricity and roundness can be controlled within a very small range to meet the strict requirements of the high-end manufacturing field.
(2) Reduce vibration and error: Since the mobile structure design of the grinding wheel frame is more reasonable, the vibration generated during the processing is relatively small. This helps to reduce processing errors and improve the surface quality and dimensional accuracy of the workpiece. Ordinary cylindrical grinders may be affected by factors such as the bed structure and transmission system during the processing process, resulting in large vibrations, thereby affecting the processing accuracy.
2. Higher processing efficiency
(1) Fast feeding and positioning: Wheel Head Moving Cylindrical Grinder is usually equipped with advanced CNC system, which can achieve fast feeding and positioning. Operators can control the moving speed and position of the grinding wheel frame through programming, which greatly improves the processing efficiency. In contrast, the feeding and positioning methods of ordinary cylindrical grinders are relatively traditional, the operation is more cumbersome, and the processing efficiency is low.
(2) Multi-station processing: Specific Wheel Head Moving Cylindrical Grinder can also realize multi-station processing, that is, multiple workpieces can be processed on one grinder at the same time. This not only improves the processing efficiency, but also reduces the equipment footprint and production cost. Ordinary cylindrical grinders can generally only perform single-station processing, and the processing efficiency is subject to certain restrictions.
3. Stronger adaptability
(1) Can process complex-shaped workpieces: Wheel Head Moving Cylindrical Grinder can adapt to the processing of workpieces of different shapes by adjusting the position and angle of the grinding wheel frame. For example, for some shaft parts with complex shapes such as steps, tapers, and arcs, this grinder can easily complete the processing tasks. When processing workpieces with complex shapes, ordinary cylindrical grinders may need to use special fixtures or perform multiple clamping, which increases the difficulty and cost of processing.
(2) Can process workpieces of different materials: Since the grinding wheel of the mobile grinding wheel frame cylindrical grinder can be selected and replaced according to the different workpiece materials, it can process workpieces of various materials, such as steel, cast iron, non-ferrous metals, etc. When processing workpieces of different materials, ordinary cylindrical grinders may need to adjust processing parameters or replace grinding wheels, and their adaptability is relatively weak.
4. More convenient operation
(1) Easy operation of CNC system: Wheel Head Moving Cylindrical Grinder is usually operated by CNC system, which has a friendly interface and is easy to operate. The operator only needs to input the processing parameters and programs to realize automatic processing. In contrast, the operation of ordinary cylindrical grinders is relatively complicated and requires operators to have a high level of skills.
(2) Convenient maintenance: Since the structural design of Wheel Head Moving Cylindrical Grinder is more reasonable, maintenance is relatively convenient. For example, the replacement and repair of some key components can be completed in a shorter time, reducing the downtime of the equipment. When maintaining ordinary cylindrical grinders, it may be necessary to disassemble more parts, and the operation is more cumbersome.
There are four main types of Wheel Head Moving Cylindrical Grinder of Shanghai ANTISHICNC: program-controlled support wheel head moving cylindrical grinder, CNC support test wheel head moving cylindrical grinder, program-controlled top wheel head moving cylindrical grinder, and CNC top grinding machine.
1. Top grinding type machine can grind heavy parts with top grinding, which is easy to operate and efficient. The machine tool structure adopts the structure of mobile external cylindrical grinding machine with grinding wheel frame. The workpiece only rotates, the grinding wheel frame carriage (Z axis) makes longitudinal reciprocating motion on the carriage bed, and the grinding wheel frame (X axis) makes lateral feed motion on the carriage. The structural layout of the operating position is on the carriage.
2. The bed structure of the external cylindrical grinding machine is that the workpiece bed and the carriage bed are cast into one. The external cylindrical grinding machines with a diameter of more than 800 all adopt the separation structure of the workpiece bed and the carriage bed. The longitudinal Z-axis transmission part of the carriage is driven by a servo motor and a rack and pinion transmission, and some CNC machine tools with a length of less than 5 meters use a servo motor driven ball screw transmission. The horizontal X-axis of the grinding wheel frame is all driven by a servo motor and a ball screw transmission.
3. The longitudinal guide rails of the carriage and the transverse guide rails of the grinding wheel frame are both unloaded static pressure guide rails, which are stable at low speed.
4. The main shaft of the grinding wheel frame adopts a high-rigidity dynamic and static pressure main shaft, which has high rotation accuracy, good rigidity and high cutting quality.
5. The headstock and tailstock spindles of the top grinding machine are both rotating live spindle structures. The spindles are supported by ultra-precision rolling bearings, with strong lubrication of thin oil, high positioning accuracy and large load-bearing capacity. The rotation accuracy of the top grinding machine is completely guaranteed by the accuracy of the high-precision bearings selected for the head and tailstocks, so the grinding quality is high.
6. The top grinding machine can be equipped with a four-jaw chuck, which can realize grinding in a clamping and top manner.
