With a high speed precision lathe, the finish of the finish of the finish of the finish should reach

The finish of the outer circle of the high-speed precision lathe can be achieved by the selection of turning tools, and the CBN tool can be used to finish the turning tool after heat treatment: small feed, high speed (considering the speed according to the actual performance of the machine tool), and the arc radius of the tool tip is small (R=or can be used).

1.Rake angle: the rough turning angle is smaller, and the fine turning is larger.

2.Rear angle: rough turning angle is small (6-8 degrees), fine turning is larger (10-12 degrees).

3.Blade inclination: 5 degrees is generally taken when rough turning, and 10 degrees or greater can be taken when there is a large vibration;

-4 degrees is generally taken when finishing.

4.Entering angle: selected according to the stiffness of the machine-workpiece-tool process system.

5.Sub-declination angle: selected according to the surface finish, the declination angle is small when the requirements are high.

6.Arc radius of the tool tip: general carbide turning tool r=, small value for rough turning.

Unless aluminium or its alloys are being processed, the roughness of ordinary steel materials is not possible on lathes.

With diamond tools, hydrostatic bearing spindles, and a special speed of 5000-10000, aluminum products can be processed into mirrors.

Dude corrects you :

The lathe did not reach 5,000 to 10,000 revolutions, of course, except for the instrument lathe, but unfortunately his bed was not that kind. There is a diamond turning tool that he can withstand the highest temperature is eight. If you do that one revolution, you don't know how many times you have to change the blade.

The cost is not affordable for the average person.

The landlord gives you a suggestion, if the ordinary steel is turned with a spring light knife, add a high concentration of emulsion as the cutting fluid. Then roll it with a roller to almost achieve the roughness you want, but the accuracy is about five ways of adding or subtracting.

Generally on the grinder! It is difficult to achieve ordinary lathes, you go to buy ty30 knives or buy imported cutter heads to try it, but it should not be able to reach ,, can be achieved!

Finishing is generally a frame cutter, mainly depending on what material the parts are.

Then the knife block generally has a description of what material to use, the main thing is human operation, there is a certain ratio of feed speed and rotational speed, these are the basic operating theories.

YT726 plus repair blade parallel to the longitudinal guide rail high speed.

Possible reasons for the lack of lathe finish: 1. The spindle vibration, this possibility is the largest, and the runout of the spindle is too large during the movement; 2. The tool holder jumps; 3. The spindle speed is unstable; 4. Whether the clamped workpiece is firm or not, it can also be said that it is a problem of clamping; 5. Process problems.

Lathe inspection: 1First, check whether the Z-direction ball screw is damaged due to external force. Inspection method: You can disconnect the screw nut and the middle carriage, move the screw nut by hand to see if there is a dead point, and if there is no dead point, it proves that the ball screw is not damaged.

2.Check the bearings at both ends of the ball screw for damage. On the premise of disconnecting the ball screw screw socket, disconnect the screw and the coupling of the servo motor, rotate the screw by hand, and feel whether there are hard spots with your hands.

3.Check the middle carriage of the ball screw wire socket to see if it is in a state of suffocation due to strong impact, which affects the surface finish.

1.Rake angle: small rough turning angle, fine turning.

The bai is larger.

2.Rear angle: rough turning angle du is small (6-8 degrees), fine turning zhi is larger (10-12 degrees).

dao3.Blade inclination: 5 degrees is generally taken when rough turning, and 10 degrees or greater can be taken when there is a large vibration;

-4 degrees is generally taken when finishing.

4.Entering angle: selected according to the stiffness of the machine-workpiece-tool process system.

5.Sub-declination angle: selected according to the surface finish, the declination angle is small when the requirements are high.

6.Arc radius of the tool tip: general carbide turning tool r=, small value for rough turning.

When the outer circle of the rough turning can eat the knife larger, generally in 3-4 mm, the angle of the tool is smaller, the arc angle of the tip of the knife is larger, and the 90-degree left deviation knife can be. When finishing the car, the margin is left a little less, generally left, and the speed is higher. The tip of the knife has a smaller arc angle. Hope it helps.

Rough turning is the car to go to the more than the surplus part of the system, leaving a small amount of margin to the finishing turning, each part bai is required du, such as tolerance, smoothness, etc., these are determined by the finishing turning, so when the finishing turning, the number of revolutions and the feed are in a pair of proportions, for the tool angle, the rough turning angle is larger, the tool durability point, the finishing turning, the angle is smaller, sharper, can be processed to the ideal size and requirements.

The selection of the three parameters of cutting is necessarily different;

The difference in the cutter is mainly the tip angle, and the fine turning is r larger.

What is the diameter of the lathe, which is about 15+-20 millimeters, and the required finish, how many revolutions of the lathe, and how much is the speed of the tool.

Hello, glad to answer for you. When the lathe processes the outer circle with a diameter of 15-20 mm, the required finish of the lathe is generally revolutionary. Here are some general reference values, just for reference:

1.Lathe speed: In general, the speed of lathe processing of the outer circle is generally 100-200 rpm.

The specific speed needs to be determined according to factors such as workpiece material, hardness and turning tool type, and generally needs to be tested and debugged. 2.Passing speed:

The passing speed of the lathe processing of the outer circle is generally rotation. The specific pass speed needs to be determined according to factors such as lathe speed, workpiece material, turning tool type and machining depth. 3.

Finish: The finish requirements of the machining outer circle require sufficient cutting fluid cooling and adjustment of cutting parameters to ensure the flatness and finish of the machined surface of the lathe. At the same time, it is also necessary to carry out sufficient post-treatment processes such as cleaning and polishing to achieve better surface quality.

I hope mine can help you, and Pi Qin wishes you a happy life!

Dear, I am glad to answer for you: What kind of tool accuracy and finish are used for CNC machining arc surface Answer: CNC machining arc surface with CNC end mill machining center tools are mainly divided into two categories: milling tools and hole processing tools.

The choice of milling tool is mainly the choice of milling cutter type and cutter size. The type of milling cutter should be adapted to the surface shape and size of the workpiece. Face milling cutter should be selected for machining larger planes; When machining grooves or small steps and plane profiles, end mills should be selected; Ball nose milling cutter should be selected for machining surfaces; Molds are often used to process mold cavities or punch forming surfaces; Machining closed keyway selection keyway cutter; Drum milling cutter should be used for machining variable bevel surface; Forming milling cutters should be used for processing various straight or arc-shaped grooves, beveled surfaces, special holes, etc.

When rough milling or milling is not important machining planes, coarse tooth milling cutters can be used; When finishing milling, a close-tooth milling cutter can be used to achieve low surface roughness with a small amount of slag liquid; When milling hard metals, close-pitch cutters must be selected and the feed should be small to prevent vibrations. The size of the milling cutter should also be adapted to the surface size and shape of the workpiece to be machined. The selection of the tool diameter mainly depends on the specifications of the equipment and the machining size of the workpiece, and it is also necessary to consider that the power required by the tool should be within the power range of the machine tool.

The cutter diameter should be smaller for rough milling and larger for fine milling, preferably to accommodate the entire machining width. When the surface requirements are high, you can also choose to use a blade with a polishing effect.

The accuracy that can be achieved by machining the outer surface is not a maximum value, but a range value, because it is affected by many factors, and it is impossible to determine the specific reference.

Influencing factors: This is related to the skill level of the operator; It is related to the model of the machine tool and the accuracy of the machine itself; It is related to the material and machinability of the material to be processed; When the lathe processes the outer surface of the outer circle, the machining method, the machining tool, the machining cutting technical parameters, and the diameter of the processed outer circle are closely related to each other.

Expansion: Lathe machining is a part of machining, and there are two main forms of processing: one is to fix the turning tool and process the unformed workpiece in rotation; The other is to fix the workpiece and perform precision machining through the high-speed rotation of the workpiece and the lateral and longitudinal movement of the turning tool.

Provisions: 1. When aligning the workpiece, it is only allowed to use the hand plate to move the chuck or open the lowest speed to align, and it is not allowed to open the high-speed alignment.

2. When changing the direction of rotation of the spindle, it is necessary to stop the spindle first, and it is not allowed to change the direction of rotation suddenly.

3. When loading and unloading the chuck, it is only allowed to rotate the V-belt by hand to drive the spindle to rotate, and it is absolutely forbidden to directly start the machine tool to be forced to loosen or tighten. At the same time, a wooden board should be placed on the bed surface to prevent accidents.

4. The installation of the cutter should not be stretched out too long, the gasket should be flat, and the width should be consistent with the width of the bottom surface of the cutter.

5. It is not allowed to drive the reverse car to brake the spindle rotation during work.
