What is the effect of the accuracy of the cylindrical grinder, and what is the effect of the uneven

What about an internal cylindrical grinder? This question cannot be generalized and should be analyzed according to your specific situation. Here is a brief introduction to the characteristics of internal grinding machines for your reference.

The feeding and compensation of the machine tool is carried out by two transmission mechanisms that do not interfere with each other. The feed system has a fixed path grinding function, and adopts two feeding methods: manual or hydraulic. The machine is equipped with a quick-jump mechanism, so there is no need to manually set the tool again after exiting the grinding wheel for measurement or dressing.

The workbench is equipped with a stop device, and the distance can be adjusted as needed to reduce the auxiliary time. The workbench starter handle is equipped with a safety interlock device to ensure safety during loading, unloading and measuring work. The machine tool has a high grinding wheel spindle speed of 24,000 rpm to improve the grinding of small holes.

User-specific orders. The motor spindle can be modified to adjust the frequency conversion speed to grind the small diameter inner hole. This machine is equipped with an end face....

1: The influence of the equal height of the grinding head, headstock and tailstock on the dimensional accuracy of the workpiece.

The equal height error of the grinding head, headstock and tailstock will make the center line of the headstock and tailstock and the axis of the grinding wheel spindle offset in space, and the surface of the grinding workpiece will be a hyperboloid surface.

2: The influence of the parallelism error of the center line of the head frame and tailstock on the axis of the grinding head spindle in the horizontal plane on the dimensional accuracy of the workpiece.

When this error occurs, the shape of the workpiece on the cylindrical grinder will be a cone, i.e. the grinding wheel is ground at an angle with a spiral grinding surface.

3: The influence of the verticality error of the grinding head movement relative to the guide rail of the machine tool on the machining accuracy.

The final result of this error is to offset the spindle axis and the center line of the headstock and tailstock, and the perpendicularity error between the shaft shoulder end face and the workpiece axis will be caused when the shaft shoulder end face is grinded. When grinding the outer cylindrical, the surface roughness will be affected, resulting in a spiral grinding pattern.

Hello dear! We are glad to answer for you: the influence of the uneven level of the cylindrical grinder on the equal height of the grinding head, headstock and tailstock on the simple accuracy of the workpiece standard.

Related Extensions:Related Extensions: The outer circular fiber grinding machine is a grinding machine for processing the outer surface of the cylindrical, conical or base shape of the workpiece and the end face of the shaft shoulder; The most widely used, can machine all kinds of cylindrical conical outer surface and shoulder end face grinding machine.

The cylindrical grinder is the most widely used type of machine tool, which is generally composed of the cast iron bed of the basic part, the worktable, the headstock and tailstock that support and drive the workpiece to rotate, the grinding wheel frame (grinding head) that installs the grinding wheel, the transverse feed mechanism that controls the size of the grinding workpiece, and the electrical appliances and hydraulic devices that control the action of the moving parts of the machine tool.

Summary. Hello, I'm glad to answer for you, the roundness of the workpiece with a small diameter of the cylindrical grinder is not enough, the center hole is not (that is, the positioning datum is unqualified), and there is a flat phenomenon when grinding. Solution: Use the alloy 60-degree grinding center to grind the center hole and round it.

Second, the shape of the work is complex, there is a tendency to deviate from one side, and the grinding is not round. Solution: Add counterweight to the deviation of the workpiece and grind evenly. Third, the lack of coolant produces the phenomenon of stabbing the knife, and the coolant is increased.

What should I do if the roundness of the workpiece with a small diameter of the cylindrical grinder is not enough.

Pro, we can solve this problem by adjusting the grinding wheel spindle bearing clearance of the cylindrical grinder.

Dear, I am glad to answer for you that the roundness of the workpiece with a small diameter of the cylindrical grinder is not enough to solve the problem as follows: if the center hole of the workpiece is unqualified, grind the center hole of the workpiece to an accurate angle, and its roundness error meets the requirements; If the top of the headstock and the top of the tailstock are in poor contact with the shaft taper, and there is shaking during operation, the top should be removed to check whether there is a burr on the contact surface and repair it with burrs; When the center of the headstock and tailstock is worn, the center should be polished to correct the center angle, and the cemented carbide center should be used; When the coaxiality of the axis of the center hole at both ends of the workpiece exceeds the tolerance, the center hole of the workpiece is re-grinded; If the workpiece is pushed too tightly or too loosely, readjust the tailstock position;

Hello, it is a pleasure to serve you. There may be a variety of reasons for the lack of finish of the cylindrical grinder, and the following are some possible factors: the grinding process parameters are unreasonable, the grinding process parameters of the cylindrical grinder include grinding speed, feed, grinding wheel particle size, etc., and whether the setting of these parameters is reasonable will directly affect the grinding effect.

If the grinding speed is too fast, the feed is too large, or the grinding wheel size is not suitable, it may result in an unsmooth grinding surface and an insufficient finish. The grinding wheel is the core component of the cylindrical grinder, if the grinding wheel is severely worn, it will affect the finish of the grinding surface. Grinding wheel wear can be caused by long grinding time, excessive grinding force, or poor grinding wheel quality.

The grinding fluid is a necessary auxiliary medium in the grinding process of the cylindrical grinder, which can cool the grinding area, lubricate the grinding wheel and the surface of the workpiece with coarse or silver, and clean the grinding area. If the grinding fluid quality is not good, such as too many impurities, too high or too low pH, etc., the finish of the grinding surface will be affected. The surface quality of the workpiece is not good, and the surface quality of the workpiece ground by the cylindrical grinder has a great influence on the final grinding result.

If there are cracks, bumps, or other surface defects on the surface of the workpiece, it may result in an unsmooth grinding surface and an insufficient finish. Further analysis is required on a case-by-case basis to find the specific cause of the problem and take corresponding measures to improve the finish of the grinding surface.

Summary. The main difference between an end cylindrical grinder and a cylindrical grinder is the different parts being ground. The end face cylindrical grinder is mainly used for grinding the end face and outer circle of parts, and is suitable for parts processing with high requirements for precision and surface quality; The cylindrical grinding machine is mainly used to grind the outer circle of parts, and is suitable for machining workpieces with long length or large diameter.

In addition, the two are also different in structure, the end face cylindrical grinder is mainly composed of a spindle box, a slide table, a fixture, etc., and the cylindrical grinder is composed of a grinding head spindle, a grinding head slide table, a workpiece bearing, a fixture, etc.

Can you add, I don't quite understand it.

The main area of the face cylindrical grinder and the cylindrical grinder is different in the parts to be ground before the opening is raised. The end face cylindrical grinding machine is mainly used for grinding the end smile side and outer circle of parts, and is suitable for the processing of parts with high requirements for precision and surface quality; The cylindrical grinding machine is mainly used to grind the outer circle of parts, and is suitable for machining workpieces with long length or large diameter. In addition, the two are also different in structure, the end face cylindrical grinder is mainly composed of a spindle box, a slide table, a fixture, etc., and the cylindrical grinder is composed of a grinding head spindle, a grinding head slide table, a workpiece bearing, a fixture, etc.
