Citizen swiss-type Automatic Lathe
The working principle of CNC lathe
CNC Turning is rotating tool to cut the workpiece, cnc turning parts is rotated rather than the tool. turning parts manufacturing is the most basic and common cutting. cnc turning services is suitable for machining rotating surfaces. Most precision turning parts with rotating surfaces can be done by turning methods, such as inner and outer cylindrical surfaces, inner and outer conical surfaces, end faces, grooves, threads, and rotating forming surfaces. The tools used are mainly turning tools.The material can be aluminum, brass, stainless steel and steel.

Surface treatment of precision turning part
Suitable for CNC turning surface finish, which can change the appearance, roughness and corrosion resistance of parts.
Surface effect after turning
Stainless steel Ra1.0um~Ra1.6
Applicable material: aluminum, stainless steel, copper
|The parts use 120#~220# glass sand, the granular surface formed under the pressure of 0.6-0.8mpa
Anodizing + 2 times Anodizing + 3 times Anodizing
|Anodizing can enhance the wear resistance,corrosion resistance,the surface hardness.
Polishing + electroplating
|A layer of metal film is attached to the surface of metal parts or non-metal parts through electrolysis, so that the outer surface is not only beautiful, good chemical resistance, but also improves surface hardness.
Applicable material: stainless steel, titanium, copper
|Ion plating (PVD coating) technology, with its high hardness, high wear resistance, strong corrosion resistance, high temperature resistance, adhesion resistance and other superior performance.|

FAQ in CNC turning
How to choose the pressing method of the tool bar?
Which compression method is the most reasonable?
How can I quickly learn about turning tools?
If you want to choose a suitable turning tool, what information should you know first?
1. The first choice is to understand which machine tool plant it is used in, that is, to understand its tool square and maximum speed, and also the stability of the machine.
2. The drawings of the processed parts, which are to be processed? Are they rough or finished? Are there special requirements? What is the precision? What material is processed?
3. What grade of tools can the customer accept?
What should be paid attention to when processing titanium alloys?
itanium alloy turning is easy to obtain better surface roughness, work hardening is not serious, but the cutting temperature is high, and the tool wears quickly. In view of these characteristics, the following measures are mainly taken in terms of tools and cutting parameters:
Tool geometry parameters:suitable front and rear angles of the tool, tool tip rounding. Lower cutting speed, moderate feed rate, deeper cutting depth, and sufficient cooling. When turning the outer circle, the tool tip cannot be higher than the center of the workpiece, otherwise it will be easy to pierce the tool. When finishing turning and turning thin-walled parts, the tool lead angle should be large, generally 75-90°. Titanium alloy should consider the cutting or wear resistance of the blade.
Titanium alloy belongs to the category of non-ferrous metals, and must be cut and the blade wear-resistant. It is best to use a blade with a smaller tip angle and a larger clearance angle.
How to select the cylindrical tool holder and what issues should be paid attention to?
It is very important to choose an external circular knife because of its knife square and entering angle, as well as its installed blade. The knife square is configured according to the machine. Selection of Tool Holder Head Forms There are 15 to 18 types of tool holder head types according to entering angle, straight head and offset head. The corresponding codes are specified for each form. The national standards and tool catalogs are all listed in the national standard and the tool catalog. Choose according to the actual situation. For workpieces with right-angle steps, you can choose a toolholder with a deflection angle greater than or equal to. For general rough turning, 45°～90° entering angle is optional; for fine turning, 45°～75° optional; middle cutting and profiling, optional 45°～107.5°; optional when the process system is rigid The smaller value, when the rigidity of the process system is poor, the larger value can be selected. The blade depends on the requirements of its processing drawings.
