How to turn the chamfer of the inner hole on the left side of the CNC lathe

If the workpiece is only a hole in the car, use a hook cutter, two cutter edges, and add the width of the knife when programming, which can directly chamfer on the left side and the end face of the car.

CNC machine tool is the abbreviation of digital control machine tool, which is an automatic machine tool equipped with a program control system. The control system can logically process the program specified in the control code or other symbolic instructions, and decode it, represent it with the number of **, and input the numerical control device through the information carrier. After calculation and processing, various control signals are sent by the numerical control device to control the action of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing.

CNC machine tool better solves the problem of complex, precise, small batch, multi-variety parts processing, is a flexible, high-efficiency automatic machine tool, represents the development direction of modern machine tool control technology, is a typical mechatronics products. It has been widely used in modern industry, which greatly improves the production efficiency of enterprises.

If the workpiece is only an inside hole, with a hook cutter, two knife points! You can chamfer and face the car directly on the left! That's what I'm doing right now!

Use a reverse hook knife car or a positive knife car with a small angle.

Towering and upright. Describe the woman as slender. It is also described as a tall body such as flowers and trees.

The question you ask is strange, what is a "left chamfer"?

Commonly used 1 45 chamfer, the length of each right-angled side of the inverted part is 1mm, when CNC programming, G01 goes diagonally, the length of the Z direction is 1mm, and the X diameter direction because the workpiece is rotating, the calculation should be calculated by 2 times, such as the outer diameter of the workpiece is 25mm, and the chamfer is 1 45 on the outer circle.

Mounted on a bed rail, and moved longitudinally along this rail to adjust its working position. The tailstock is mainly used to install the rear center to support a long workpiece, and can also be installed with drills, reamers, etc. for hole processing.

Regarding CNC lathe chamfering, there are such algorithms for C angle and R angle, and automatic chamfering is actually simple.

You can use g01 to walk the slash directly

The chamfer of a CNC lathe may be due to the following reasons:

1.Uneven tool wear: When the same tool is used for multiple machining, the chamfer size will be inconsistent due to uneven tool wear. At this time, the tool should be replaced and corrected.

2.Deformation of the workpiece: During the turning process, especially in the case of a large amount of cutting waste, insufficient cutting cooling, excessive turning depth and speed, etc., the workpiece may be deformed, resulting in inconsistent chamfer size.

3.Error of lathe: CNC lathe is a mechanical equipment, and there is a certain error in itself. If there is a problem with the writing of the CNC program, or the accuracy of the lathe itself cannot meet the processing requirements, arguing may also lead to the problem of inconsistent chamfer size.

In response to this situation, the following measures can be taken: Carry the balance.

1.Replace the tools regularly and maintain the lathe.

2.Optimize CNC programming to reduce machining errors.

3.Strengthen cooling and lubrication in processing, control parameters such as processing depth and speed.

4.The workpiece is fixed to avoid deformation.

Summary. The formula for calculating the outer chamfer.

Example: 30 diameter outer end chamfer.

Program: GO X32 Z2

1. The diameter of the starting point of the chamfer is x= 2xaxtan ° x= g1 z02, the length of the starting point of the chamfer is z=0 where tan60° is found by the mathematical table g1 x303, and the diameter of the chamfer closing point is x= g1 z-50

4. The length of the chamfer is z= -a.

CNC lathe chamfered inner corner.

Example of the calculation formula of the outer circle inverted guess is Cong Zhaobo: 30 diameter of the outer end of the seepage auspicious chamfering program: go x32 z21, chamfer starting point diameter x= 2xaxtan ° x= g1 z0, chamfer starting point length z=0 where tan60° is found by the mathematical table g1 x30, chamfer closing point diameter x= g1 z-504, chamfering closing point length z= -a.

This pro. Inner angle r

The reason for the starting point of the formula knife processing technology is based on the above-mentioned so (13 2) diameter programming) the end point position of the knife seepage start x13 can be generally, if you want to use the final cluster to read such as the point programming, the height above the chamfer r angle can be reversed.

CNC car inner hole, how to calculate 30 degree chamfer.

The method of calculating the 30-degree chamfer of the inner hole of the CNC car is as follows: determine the diameter of the inner hole: first of all, you need to determine the diameter of the inner hole, which will be the benchmark value in the calculation process.

Calculate chamfer width: The chamfer width (w) is the distance from the surface of the inner hole to the chamfer intersection point. The chamfer width can be calculated using the following formula:

w = d * tan(a) where d is the bore diameter, a is the chamfer angle (30 degrees here), and tan is the tangent function. Calculate the chamfer length: The chamfer length Song Xun (l) refers to the length of the chamfer along the axis of the inner hole.

The chamfer length can be calculated using the following formula: l = w tan(a) where w is the chamfer width, a is the chamfer angle (30 degrees here), and tan is the tangent function. Calculate chamfer radius:

The chamfer radius (r) refers to the radius of curvature from the surface of the inner hole to the chamfer intersection. The chamfer radius can be calculated using the following formula: r = w sin(a) where w is the chamfer width, a is the chamfer angle (30 degrees here), and sin is a sinusoidal function.

It should be noted that when carrying out CNC car inner hole chamfering processing, it is also necessary to consider the diameter of the cutting tool, the processing depth and other factors, so as to ensure the processing effect and the quality of the workpiece. Hail sold.
