What machine tool is used to mill the end face of the shaft with a diameter of 200 and punch the cen

Diameter 200 shaft parts milling end face, punching center hole processing using milling end face punching center hole machine tool, high efficiency, good machining accuracy, good processing consistency, in the batch or shaft high-precision processing milling end face punching center hole machine tool has a unique advantage.

The selection of the milling face to punch the center hole machine needs to select the model according to the diameter range and length range.

Milling end face punching center hole CNC machine.

It can meet the processing of shaft parts with a diameter of 500mm and a length of 10 meters.

The functions cover: milling the end face, drilling the center hole, casing the outer circle, chamfering, drilling deep holes, tapping and other functional forms of processing.

The center hole of the automatic lathe is made on the retaining arm. Grinding center drill: Generally, the head is ground into a center drill (the center drill bit is 90 degrees or 60 degrees) with a white steel rod with a diameter of 6mm.

Load the center drill into the retaining arm, adjust the center hole cam according to the requirements of the workpiece, and then adjust the distance between the retaining block and the center drill.

Using the milling face to punch the center hole machine, we have purchased two sets in the factory, not a manufacturer, but the quality of Wuxi, Jiangsu Province is better in comparison.

According to the different accuracy requirements of the hole, different process steps are adopted, and different tools are selected

1. The hole with an accuracy of IT6 should be ground by grinding process, and the higher precision should be grinded.

2. The hole with an accuracy of IT7 can be reamed or boring for 1 2 times.

3. For holes with an accuracy of IT8, you can use a reaming or boring.

4. If the accuracy is lower, it can be achieved by expanding, boring, milling, etc.

According to the different scope of use of the tool, choose different tools:

1. The maximum diameter of high-speed steel drill bits is generally less than 100 mm.

2. The diameter of the integral cemented carbide drill bit is generally below 20 mm, and a few to 25 mm.

When the CNC machining center processes the hole, how large the diameter of the tool is used to determine how to process it according to the accuracy of the hole. For larger holes with high precision requirements, it is necessary to drill the bottom hole with a smaller drill bit first, and then replace it with a larger drill bit to ream. Finally, the hole can be bored to the size; For smaller integer holes, you can drill the bottom hole first, and then ream, leaving the reaming margin or so.

Then use a reamer to twist the hole to size; In order to ensure the position accuracy of the hole, before making the hole, it is necessary to drill the hole with the center first, and then drill the hole. If you drill the hole directly with a drill bit, the position of the hole will be discrewed. If you boring the hole with a boring cutter, you won't have this problem.

When boring with a boring tool, after many boring holes, the holes that have been deviated can be corrected.

The machining center fine boring inner hole pass and rotation speed is rough machining according to each revolution, fine boring is generally taken per revolution. The specific parameters of the pass and rotation speed of the fine boring inner hole of the machining center will vary depending on the brand, model and processing material of the machining center. In general, according to the diameter and depth of the hole, as well as the required machining accuracy, it is necessary to determine the most suitable pass and rotation speed based on experience and experimentation.

The hole diameter is more than 30 internal hole processing, and the cutting tool generally used is a drill or reamer. The rotational speed will vary depending on the specific tool, the type of steel, and many other factors. Generally speaking, the rotation speed of the tool should be determined according to the workpiece material of the reamer, the hole diameter and the required machining accuracy.

In the case that the accuracy requirements of Richarder are not very high, the rotation speed is generally about 500-1000r min. In the case of higher requirements, it is necessary to increase the speed accordingly to increase the cutting force and machining efficiency, and at the same time, it is necessary to pay attention to protect the reamer from excessive wear and tool damage.

Summary. Hello dear, happy to answer your <>

When the machining center finishes boring the inner hole, the choice of pass and rotation speed depends on the material and accuracy requirements of the machined parts. Generally speaking, the use of single-tooth or double-tooth microcomputer positioning milling cutter with a diameter slightly smaller than the machining hole, the pass speed is recommended to choose a lower speed (such as 2-4m min), and the speed depends on the diameter and material of the milling cutter, which can be determined according to the manufacturer's recommendation or actual test of the milling cutter. At the same time, in order to reduce burrs and improve surface quality, the cutting feed (such as the edge) and the rotation speed (the speed range is generally about 2000rpm) can be adjusted appropriately.

What is the speed of the machining center's fine boring inner hole and rotation, and the more than 30 holes are good for the macro, hello Zhusen, I am happy to answer the <> for you

Kiss, and then there is <>

In the case of 30 surplus holes, it should be noted that when setting the machining parameters of the machine tool, the size of the allowance should be taken into account, and the parameters such as tool feed speed, cutting depth, and rotation speed should be reasonably adjusted to ensure that the hole size and surface quality of the virtual processing meet the requirements.

It can be fixed on one side, and the other side is moved and clamped in a way that rocks fail, and a pair of special washing fixtures and special drill fixtures for end milling are designed. Both sides of the length direction can be adjusted by the screw rod at the same time. Reach the required length of the ruler to open the inch.

The positioning of the center hole can be in the form of hydraulic automatic positioning.
