What is the drive system of an internal grinding machine? 5

The hydraulic system of the cylindrical grinder is mainly used to control the movement of the cylindrical grinder, so that it can achieve high-precision and high-speed work. The hydraulic system realizes the machining task of cylindrical grinders by compressing the liquid and transporting it to the hydraulic cylinders, which pushes the motor and other mechanical parts to move. Its main implications include:

1.Achieve high-precision machining: The hydraulic system can control the accuracy and speed of the cylindrical grinder to achieve precise machining tasks.

The hydraulic system can directly convert the hydraulic oil pressure into linear motion, so that the movement of the tool holder, grinding wheel and workpiece can be accurately controlled to achieve high-precision machining results.

2.Increased productivity: The hydraulic system is characterized by fast response and can achieve a variety of linear movements and position adjustments required during machining in a short time. This increases the productivity of the cylindrical grinder and makes machining costs lower.

3.Improve the quality of work: The accuracy and quality of work of the cylindrical grinding stage are directly related to the quality of the hydraulic system. The hydraulic system can accurately control the movement of the tool holder, grinding wheel and workpiece, so as to ensure the stability and consistency of the dimensional and surface quality of the machined workpiece.

4.Easy to maintain and operate: The hydraulic system structure is relatively simple, reliable, and easy to maintain. At the same time, the hydraulic system controls the movement in a flexible and convenient way, and the processing parameters can be adjusted according to the processing needs at any time, providing a more reliable processing control method.

a.The movement of the table.

b.Rotational motion of the grinding wheel.

c.The rotational motion of the workpiece.

d.The draft of the grinding wheel frame guesses the movement of the Moriyu.

Correct Answer: The rotational motion of the grinding wheel.

Kiss. Hello, I am glad to answer for you: the reason why the cylindrical grinder does not commutate left and rightA:

Hello, the reason why the cylindrical grinder M1432B of Shanghai Machine Tool does not move left and right: check whether there is a problem with the reversing valve of the grinder, resulting in abnormal reciprocating operation or immobility of the left and right sides, and finally check whether the reversing handle switch is loose and worn by parts. By removing the hydraulic reversing valve and cleaning and repairing it with diesel fuel can solve the problem, if the effect is not good, it can only be replaced with a new hydraulic reversing valve.

It is also possible that the grinder can not move left and right in the opposite direction is your setting problem This is obviously an automatic machine driven by hydraulic pressure First replace it manually, move it, if you can't move it manually, the group is no problem, then you have to check whether the two-way door of the oil cylinder is closed, and the oil is not circuited due to the collapse, and the direction can not be moved! Open the cylinder door and you're ready to use! In addition, one of the left and right directions runs out of the limit and gets stuck, which is also this phenomenon!

When the cylindrical grinding machine is processed, the rotation around the axis of the workpiece and the passing of the grinding wheel obtain a rotating surface on the workpiece; The surface grinding machine is a translational motion driven by the workpiece for the worktable, and the grinding wheel is translated along the direction at a certain angle to the direction of movement of the workpiece, and the result of motion synthesis is to cut a plane on the workpiece.

A type of grinder. Mainly use the grinding wheel to rotate and grind the workpiece to make it reach the required flatness, according to the shape of the workbench can be divided into two kinds of rectangular workbench and circular workbench, the main parameter of rectangular workbench surface grinder is the width and length of the worktable, and the main parameter of the circular worktable is the diameter of the worktable. According to the different types of shafts, it can be divided into horizontal shafts and vertical shaft grinders.

The cylindrical grinder rotates --- workpiece, and the grinding surface is the surface of the rotary body.

The surface grinder moves --- workpiece in a straight line, and the grinding surface is flat.

Summary. Hello, I am glad to answer your question When working, the oscillation grinding method is adopted, and the worktable is composed of two axes, X and Z, both of which are driven by ball screws by servo motors. When the cone surface with a small degree of grinding is not large, the upper stage can rotate back and forth around the first stage, and the angle of rotation back and forth is ten degrees, and the headstock and tailstock can operate together with the workbench and move back and forth longitudinally; The grinding wheel spindle is located above the table and the workpiece spindle and dressing axis are fixed.

During grinding, the worktable drives the grinding wheel shaft to move, and the surface of the workpiece is processed, and after the grinding wheel is lost, the grinding wheel is automatically trimmed by using the roller dresser.

Beds are generally used in bedrooms, dormitories, wards, hotels and other places, and refer to braces for sleeping. Using wood, stainless steel and other metals as materials, with the head and foot of the bed, the legs, the bed board mattress, the left and right folding guards, the silent casters, the integrated dining table, the shelves as the components, the use of punching, assembly, welding, riveting, rust removal, spraying and other processes.

I hope the above is helpful to you If you are satisfied with me, please give me a thumbs up

The CNC cylindrical grinder is composed of a bed, a workbench, a grinding wheel frame, a head frame, a tailstock and other components. Below, I will share with you the main functions and characteristics of the CNC cylindrical grinder, I hope it will be helpful and respectful to you!

Headframe

Headframe dial'Rotation, driven by the motor frequency conversion speed regulation, the dial rotates, the dial speed is 40-500r min segmented stepless speed change, so as to adapt to the grinding of workpieces with different diameters, different materials and different requirements.

Bed and workbench

The bed adopts large round holes and shark fin-shaped ribs, and after long-term use, the dynamic stiffness of the machine tool and the stiffness of the static call are good.

The workbench is divided into upper and first surfaces, and the conical surface can be grinded. The guide rails of the bed and the workbench are made of plastic guide rails, and the friction coefficient is small. The worktable is directly driven by the servo motor to move the ball screw, and the movement is stable and reliable.

CNC box and electrical cabinet

There is an independent CNC operation box with LCD display, machine tool operation button, 1um band compensation switch, hand pulse generator, etc.

End face gauge and radial magnator

When the CNC cylindrical grinder has a radial gauge, the measured value is automatically input into the numerical control system, and the numerical control system sends a message to make the X-direction servo motor rotate and drive the ball screw to a given position, so that the size of the grinding workpiece can stably reach the required position, and the size dispersion of the batch grinding workpiece is less than.

Grinding wheel holder

The linear speed of the grinding wheel is less than 35m s, the grinding efficiency is high, and the grinding head bearing is a three-piece pad dynamic bearing with a large bag angle, and the rotation accuracy is high. The grinding wheel frame movement (X-direction) is directly dragged by the servo motor and ball screw, and the minimum resolution is.
