What are the factors that influence the tool selection in CNC machining centers?


In the process of CNC machining, the selection of the tool is very important. The choice of the tool determines the quality of the workpiece, because there are certain requirements for the tool performance of CNC machining. Different machining parts and different batches determine the choice of tools. Let's take a look at the factors that affect the choice of CNC machining tools.

cnc machining



(1) Production batch
From the processing cost, there is a certain influence on the selection of the tool. If it is a certain part of mass production, special tools are needed, which is relatively cost-effective. However, if the tool is used to produce a single piece or a small batch, the tool is relatively expensive, so it is more appropriate to use a standard tool.

(2) Machine type
The effect of the CNC machine used to complete the process on the selected tool type. High productivity tools can be used to ensure the rigidity of the workpiece system and the tool system. For example, high-speed cutting tools and large-feed turning tools.

(3) CNC machining plan
Different types of tools are used depending on the requirements of different machining schemes. For example, the hole can be machined by drilling and reaming, and it can also be machined with a tool such as a file. The final selection is based on the machining plan.

(4) Workpiece size and shape
Different dimensions of the workpiece have a certain influence on the type of tool and the choice of specifications. For example, special surfaces require special tools for machining.

(5) Machining surface roughness
The roughness of the machined surface affects the shape and cutting of the tool. For example, when the blank is rough-milled, a coarse-tooth milling cutter can be used, and in the case of finishing, it is preferable to use a fine-tooth milling cutter.

(6) Machining accuracy
The type and shape of the finishing tool are affected by the machining accuracy when selecting, for example, the machining of the hole, drilling, reaming, reaming and boring according to the precision of the hole.

CNC machining has high precision, high efficiency, relatively concentrated machining process and fewer parts clamping times, so it has high requirements for machining CNC tools. From the point of view of the performance of the tool, the CNC tool needs to be higher than the tool used in the ordinary machine tool. Be sure to pay attention to the choice of tools.

What are the characteristics of the CNC turning process?

What are the characteristics of the CNC turning process? Turning is a method of cutting the workpiece on the lathe by rotating the workpiece relative to the tool. Turning is the most basic and common cutting processing method. Most workpieces with revolving surfaces can be processed by turning methods, such as inner and outer cylindrical surfaces, inner and outer conical surfaces, end surfaces, grooves, threads, and rotary forming surfaces. Common lathes can be divided into horizontal lathes, floor lathes, vertical lathes, turret lathes and profiling lathes, and most of them are horizontal lathes.

The Influence of CNC Turning and Milling Machining on Turning Efficiency

The cutting efficiency of CNC lathes will be affected by human factors, environmental factors and the machine tool itself. Let's talk about the influence of cutting amount and cutting tools on CNC lathe processing among many factors.   Reasonable cutting amount can improve the efficiency of CNC lathe. When the   laser  cutting  speed is increased by 10 times and the feed rate is increased by 20 times, far beyond the traditional cutting forbidden zone, the cutting mechanism has undergone a fundamental change.   The result of CNC turning  and milling combined processing is: the metal removal rate per unit power is increased by 30% to 40%, the cutting force is reduced by 30%, the cutting life of the tool is increased by 70%, and the cutting left on the workpiece is greatly reduced. Heat, cutting vibration almost disappeared; cutting processing has taken an essential leap. According to the current situation of CNC lathes, increase the feed per tooth, improve pr...

Machining and welding process notes for TC4 titanium alloy parts

Common welding methods for titanium and titanium alloys are as follows: Argon arc welding, submerged arc welding, vacuum electron beam welding, etc. Tungsten argon arc welding is used for thicknesses of 3 mm or less, and argon arc welding is done for 3 mm or more. The purity of argon is over 99.99%, and the content of air and water vapor in argon is strictly controlled. Currently, for TC4 titanium alloys, argon arc welding, plasma arc welding are often used for welding, but both methods need to be filled with welding material. Limitations on shield gas, purity and effectiveness increase the oxygen content of the joint, reduce its strength and increase its post-weld deformation. Electron beam welding and laser beam welding are used. The following is a description of precision welding and precautions for TC4 titanium alloy. 1. Weld hole problem Table of Contents 1. Weld hole problem 2, internal quality of welded part 3. Weld depth and its variation 4, j...
