CNC-508 CNC lathe adopts high-strength heavy duty cast iron, compact structure, good strength, proper hardness, low friction coefficient, and self-lubricating. The integral box structure of the base bed greatly enhances the overall rigidity and stability of the machine tool. It has the function of absorbing vibration, which reduces tool loss and improves the quality of the workpiece. It provides users with a guarantee of high efficiency and high reliability in use. Our Advantages
1. The 30° inclined layout greatly improves the bending and torsion rigidity of the machine tool at work. The integrated bed base with high rigidity and high stability provides a strong guarantee for the high precision of the whole machine.2. The spindle unit is an independent spindle (sleeve type). The high-precision spindle system has undergone rigorous dynamic balance testing, with high precision, good accuracy retention, and good thermal stability. The maximum speed can reach 4000rpm. The high precision, high rigidity, high speed and high efficiency of the spindle unit enable the whole machine to not only finish finishing, but also to perform rough machining and heavy cutting for users.
3. The tailstock is hydraulically driven, and the sleeve automatically expands and contracts with good rigidity. Users can use the panel or foot switch to control it, which saves time and effort and provides high efficiency for machine tool processing.4. The standard configuration of TJ servo turret provides users with convenient, practical and reliable machining parts.

In turning, especially finishing, how to choose tools?
First, determine the entering angle of the tool.
Among the entering angles of conventional tools, those suitable for finishing are generally between 90° and 95°, especially 91°, 93°, and 95° are used the most. The entering angle close to 90° makes the cutting force along the axis of the workpiece, and does not apply vertical force to the workpiece to avoid vibration and deformation (especially important for thin-walled parts). The entering angle is generally guaranteed on the shank.
Secondly, determine the angle of the tool nose, or you can say choose the shape of the tool.
In general, our commonly used blade forms are:
Round inserts (starting with R, ISO standard code, the same below), 90-degree square inserts (starting with S), 80 diamond inserts (starting with C), 80-degree convex triangular inserts (starting with W), 60-degree triangular inserts (starting with T), 55 degree diamond blade (D start), 35 degree diamond blade (V start).
These tool shapes basically cover more than 90% of conventional turning inserts. These inserts are arranged in terms of tool strength: R, S, C (W), D, V. The R blade has the highest strength and V the lowest. But the higher the strength, the greater the resistance caused and the greater the risk of causing vibration. Therefore, we often choose R, S, C (W) for rough machining. For finishing, we will choose D, V. The profiling capability required for finishing is also the best for V and the worst for R.
Third, determine the rake angle and the rear angle of the tool.
The negative rake angle tool has good rigidity, is not easy to chip, and is suitable for roughing, while the positive rake angle blade cuts lightly and is more suitable for finishing. There is a matching relationship between the rear angle and the front angle. Generally, the negative rake angle blade is basically a 0 degree rear angle. The positive rake angle inserts have three common clearance angles of 5° (B, ISO code, the same below), 7° (C), and 11° (P) (for turning only).
Common combinations:
CC/CP (C-type positive insert with 7°/11° relief angle), DC (D-type positive insert with 7° relief angle), VC/VB (V-type positive insert with 7°/5° relief angle) ), WB/WC (W-type positive rake angle insert 5°/7° relief angle), these combinations are also the insert shapes used for conventional finishing (the front and rear corners are all determined)
Combining the three, the tool form of conventional finishing is as follows:
95° Entering Angle Toolholder + CC Insert
93° Entering Angle Toolholder+WB/WC/DC/VC/VB Insert
91° Entering Angle Toolholder+DC/VC/VB Insert
Among them, the 93° entering angle shank + DC is the best finishing solution recommended by me (only refers to the turning radial direction). This solution allocates appropriate cutting parameters, and the processing effect should be one of the best in turning. I have tried several different materials with a roughness of 1.6, and another steel with a roughness of 0.8 because it is an inner hole and the diameter of the shank is limited, so I can only use a 95° entering angle shank + CC blade.
Of course, the above options are not the only ones. Under the condition that the medium and large diameter solid materials can reach high linear speed, the blade with 0° clearance angle (ISO code N) can also have better roughness, but the roughness at this time is more dependent on thick oxidation Aluminum CVD coated inserts are "ground" at high line speeds. This roughness is basically about one grade away from the roughness processed by the tool selected above. That is to say, I can turn it to 1.6 with the CN blade, and I can turn it to 0.8 with the DC blade.
Replenish:
The commonly used inserts in inner hole finishing are TC/TP (T-type positive rake angle insert with 7°/11° back angle)
Corresponding tool holder combination
91° Entering Angle Toolholder + TC/TP Insert
For fine turning with an inner hole diameter of more than 16, you can basically use DC inserts. However, there are two types of DC, 07 and 11. The 07 insert can process the inner hole of about 16 to 20, and the 25 and above can use the DC11 insert.
For fine turning with an inner hole of about 10 to 16, CC inserts or TC/TP inserts can be used.
If the inner hole is less than 10, generally only the CC blade is more suitable, and the Japanese system has a CC blade that can achieve 5.5-6mm.
One: outer diameter fine turning
1. PDJNR
This type of shank is suitable for fine turning of medium and large diameter workpieces. The tool holder can not only turn the outer diameter and end face, but also profile turning. It is widely used in fine cars. Moreover, the shaft parts do not interfere with the top during processing.
2. PTGNR
Suitable for fine turning of medium and large diameters. Note that this type of tool holder can only be turned on the outer diameter, and it is not suitable for the outer diameter of the car + end face.
3. STGCR and SCLCR
It is suitable for fine turning of small and medium parts, but SCLCR turning thin shafts, STGCR is not suitable for turning end faces.
4. Here comes the 'Golden Partner', SDJCR
Finish turning for all OD components, including profiling, and shafts. Suitable for any diameter. Moreover, it cuts lightly and is more resistant to chipping than VB/VC inserts. With this knife in hand, you can clean the world with precision work!
Two: inner hole fine turning
1. PDUNR
Similar to the outer diameter, this shank is suitable for fine turning of medium and large diameter parts, and it can also profile and face.
2. PTFNR
Fine turning for medium and large parts.
3. SCLCR
One of the commonly used toolholders for inner hole finishing, with a wide range of machining diameters, the minimum can be about 5.5 to 6.
4. STFPR
It is one of the commonly used toolholders for finishing turning with small and medium apertures. Generally, the machining aperture is not more than 20-25, and the minimum is about 8-10. The cutting is lighter and faster than SCLCR, and the number of blade edges is half that of CC, which is economical.
5. SDUCR
Due to the limitation of the blade shape, the minimum machining diameter of this arbor is around 14-16, so it is not as widely used as the previous two arbors.
Well, the five types of tools inside and outside can basically meet the conventional outer diameter and inner diameter finishing.
