CNC lathe machining is a kind of high precision and high efficiency automatic machine tool.  The use of it can improve the processing efficiency and create more value. The emergence of CNC lathes has freed enterprises from the backward processing technology. CNC lathe processing technology and ordinary lathe processing technology is similar. 

 

However, it should be paid attention in the following aspects.

✔️Cutting Dosage

 

For high efficiency metal cutting, the machined materials, cutting tools and cutting conditions are the three major elements. These determine the machining time, tool life and machining  quality. An economical and effective machining method must be a reasonable choice of cutting conditions.

 

Three factors of cutting conditions: cutting speed, feed and cutting depth directly cause tool  damage. With the increase of cutting speed, the temperature of the tool tip will rise, resulting in mechanical, chemical and thermal wear. A 20% increase in cutting speed reduces tool life by half.

 

The relationship between feed conditions and tool wear occurs in a very small range. But the  feed quantity is large, the cutting temperature rises, the back wear is large. It has less effect on the tool than the cutting speed. The influence of cutting depth on the tool is not as big as cutting speed and feed, but in the micro cutting depth, the hardened layer of the cutting material will also affect the life of the tool.

 

The user should choose the cutting speed according to the material being processed,  hardness, cutting state, material type, feed, cutting depth and so on.

 

The most suitable processing conditions are selected on the basis of these factors. Regular  and stable wear to life is the ideal condition.

 

How To Determine The Three Elements Of Cutting?

 

✔️Cutting Speed

 

To choose spindle revolutions per minute, you must first know what the cutting line speed  should be. Speed selection: depends on tool material, workpiece material, processing conditions, etc.

 

Furthermore, the processing condition is also an important factor. For high precision milling,  the speed is faster.

 

✔️Feed Quantity

 

F mainly depends on the roughness of the workpiece surface. When finishing, the surface  requirements are high, the amount of cutting is small: 0.06~0.12mm/ spindle per revolution. Rough processing, desirable larger. Mainly determined by the tool strength, generally can be more than 0.3, the tool after the main Angle is large when the tool strength is poor, the feed can not be too large. Also consider the power of the machine tool, workpiece and tool rigidity. Numerical control program using two units of feed: mm/ min, mm/ spindle per revolution, the above units are mm/ spindle per revolution, such as the use of mm/ min, available formula conversion: feed per minute = feed per revolution * spindle per minute revolutions.

 

✔️Tool Depth (cutting depth)

 

When finishing, generally desirable 0.5 (radius value) below. Rough machining, according to  the workpiece, cutting tools, machine tools. General small lathe (maximum processing diameter below 400mm) turning normalizing 45 steel, radius direction cutter depth is generally not more than 5mm. In addition, it should be noted that if the spindle speed of the lathe is ordinary frequency conversion speed regulation, then when the spindle speed per minute is very low (less than 100~200 RPM), the output power of the motor will be significantly reduced, at this time the depth of the tool and the amount of the tool can only be very small.
