Introduction The cylindrical grinding machine is divided into an ordinary cylindrical grinding machine and a universal cylindrical grinding machine, which can grind the outer cylindrical surface and the outer cylindrical surface of the workpiece on a common cylindrical grinding machine. The inner cylindrical surface and the inner cylindrical grinding surface can be ground on a universal cylindrical grinding machine. Conical and end faces. The main parameter of the cylindrical grinding machine is the maximum grinding diameter.

Working Ideas The cylindrical grinder uses the center of gravity as the center and the grinding wheel as the tool to grind the cylindrical steel parts to a precision concentric grinding machine (also known as a top-center grinder or a cylindrical grinder).

The structure of the host from the bed, front, rear, grinding head, drive suction devices and other components. The head, grinding head can be turned to the angle, used to trim the thimble and roller chamfer with special fixtures, dynamic balance frame, roller detector three parts ordered by the customer.

Features 1. Grinding wheel spindle bearings adopt tapered oil wedge dynamic pressure bearing, and the grinding wheel spindle still has high bearing rigidity at low speed.

2. The cross-roller guide rail is used for the grinding wheel guide rail, and the semi-automatic feeding mechanism is realized by a rotary oil cylinder.

3, tailstock shaft system has the characteristics of no gap rigidity, electrical box, hydraulic box cooling box and machine tool separation.

4, rich grinding indicator and coolant filter.

5, the head frame speed only has that AC frequency conversion stepless speed regulation.

6, the use of electrical programmable logic controller (pc), with self-diagnostic function, maintenance is very convenient.

7, optional automatic measuring instrument.

Purpose Cylindrical grinding machines are mainly used for precision grinding of end faces, outer circles and conical surfaces of batch shaft parts. They are the main equipment for automobile engines and other industries. It is also suitable for the machining of shaft parts with small batch size and high precision in the military, aerospace, and general precision machining workshops.

(1) It is used in the textile spinning industry, coarse spinning machine, draw frame, combing machine, texturing machine, etc.

(2) It is used in the production of manufacturing office communication equipment industry, fax machines, copiers, printers, cutting plotters, etc.

(3) Applicable to printing, food, and pharmaceutical industries.

Impact on the accuracy of cylindrical grinder machining 1: The influence of the height of the grinding head, head frame and tailstock on the dimensional accuracy of the workpiece.

The height error of the grinding head, headstock, and tailstock will cause the centerline of the headstock, tailstock and the axis of the grinding wheel spindle to be offset in space. At this time, the worn workpiece surface will be a hyperboloid.

2: The influence of the parallelism between the head frame and the tailstock centerline on the axis accuracy of the spindle axis of the grinding head in the horizontal plane.

When this error occurs, the external shape of the workpiece worn by the cylindrical grinder will be a cone, that is, the grinding wheel is angled and the surface has a spiral pattern.

3: Influence of grinding head movement relative to machine tool guide rail perpendicularity error on machining accuracy.

The end result of this error is that the axis of the spindle is offset from the centerline of the headstock and the tailstock. When the shoulder face of the grinding shaft is offset, the squareness error between the end face of the shoulder and the axis of the workpiece will be caused. When grinding the outer circle, it will affect the surface roughness and produce a spiral pattern.
