5. مزايا تكامل تقنية JS

• قدرة مختلطة: الآلات ، زيادة الكفاءة بنسبة 40 ٪.
• مراقبة ذكية: يحلل نظام التفتيش على جودة الذكاء الاصطناع
• Environmental adaptation: Dry cutting technology reduces cutting fluid usage by 70%, in compliance with ESG standards.

Choosing milling or turning requires a comprehensive consideration of the part shape, precision requirements, and material properties. JS can maximize the advantages of two processes through customized process solutions, such as complex surface milling (five axis linkage) and batch axis part turning (efficient automation).

How to choose suitable lathe machining tools?

1.Choose the tool material based on the workpiece material

Soft metal materials (such as aluminum, copper)

• Recommendation: Hard alloy (WC-Co) or diamond coated cutting tools. ​​
• Reason: Hard alloy has good adhesion resistance, and diamond coating can significantly improve surface smoothness (Ra ≤0.2μm).
• Example: When turning 6061 aluminum alloy, the lifespan of diamond cutting tools is more than three times longer than that of ordinary hard alloys.

High hardness materials (such as quenched steel, titanium alloys)

• Recommendation: Cubic boron nitride (CBN) or ceramic cutting tools. ​​
• Reason: CBN is resistant to high temperatures (above 1400 ℃) and suitable for high-speed cutting (Vc >150m/min), Ceramic cutting tools have low density and are suitable for lightweight cutting.
• Example: When turning gear steel with HRC50 or higher, the wear rate of CBN cutting tools is reduced by 80%.

Composite or difficult to process materials (such as stainless steel, heat-resistant alloys)

• Recommendation: Coated hard alloy or metal ceramic. ​
• Reason: Coatings can enhance high-temperature oxidation resistance (such as TiAlN coatings with a temperature resistance of 800 ℃), and the toughness of metal ceramics is better than that of pure ceramics.
• Example: When turning 316L stainless steel, coated tools can increase cutting speed by 50% compared to uncoated tools.

2.Optimize tool parameters based on processing conditions

Cutting speed (Vc)

• High speed machining (Vc >100m/min): Ceramic, CBN or diamond coated tools are preferred.
• Low speed processing (Vc <50m/min): Hard alloy has a higher cost-effectiveness.

Feed rate (f) and cutting depth (ap)

• Rough machining: large cutting depth (ap =2-5mm), medium feed rate (f =0.2-0.5mm/r).
• Precision machining: small cutting depth (ap <0.5mm), low feed rate (f <0.1mm/r), paired with sharp cutting edges (rake angle γ ≥15 °).

Cooling method

• Dry cutting: Choose high-temperature resistant coatings (such as AlTiN) or ceramic cutting tools.
• Wet cutting: Choose hydrophilic coating (such as TiN) or uncoated tools to enhance lubrication effect.

3.Tool geometric match machining requirements

• Outer circle/end turning: Tools with a main angle of 45 ° (Kr =45°) are chosen to balance radial and axial cutting forces and reduce vibration.
• Inner hole rotation: Use small rake angle (Kr =10-30°) tools to increase chip space and avoid chip blockage.
• Cutting/grooving: Use a negative rake angle (gamma =-5° to -15°) blade to improve chip ability and prevent chip entanglement.

4.Select coating process according to surface quality requirement

High smoothness requirements (Ra <0.4μm): Choose diamond (PCD) or nano coatings with a friction coefficient of 0.1 or less (e.g. AlCrN).

Resistance requirement (long service life): TiAlN/PVD coating is selected with an antioxidant temperature of 800°C and a 2-3 fold increase in abrasion resistance.

Bonding requirements (e.g. processing stainless steel): Sulphur coatings (e.g. MoS₂) or diamond-like carbon (DLC) coatings are selected to reduce the formation of wafer nodules.

How to distinguish between the two programming languages for CNC machining?

1.Different Functional Locations

Code G (geometry instructions)

Core functions: Control the motion trajectory of the machine tool and processing path, determine the movement of the machine tool.

Typical Description:

• G00: Positioning fast (non cutting movement).
• G01: Linear interpolation (cutting).
• G02/G03: Arc interpolation (clockwise/counterclockwise).
• G90/G91: Absolute/Incremental Coordinate Mode.

For example: G01 X10 Y20 F100, which represents moving directly from the current point at 100mm/ min (X=10, Y=20).

Code M (Auxiliary function)

Core function: Control the auxiliary action of the machine tool, not directly related to the cutting process.

Typical Description:

• M03: The spindle spins forward.
• M05: Spindle stops.
• M06: Switch knives.
• M08/M09: Coolant on/off.

For example: M03 S1500, the spindle rotates at 1,500rpm.

2.Differences in syntax structure

Code G

• Format: Start with the letter G followed by a number such as G01.
• Parameters: Usually include coordinate values (X/Y/Z) and feed rates (F).
• Prioritization: Execute motion commands first, directly affecting the accuracy of the processing path.

Code M

• Format: Start with the letter M followed by a number (e.g. M06).
• Parameter: There are no coordinate values, only specific functions are triggered.
• Priority: Auxiliary functions are performed at intervals between motion commands and do not affect the shape of the path.

3.Rules Execution order

Code G

• Execute program segments one by one to control the real-time movement of the tool.
• In the event of conflict (e.g. the presence of G00 and G01), the latest instructions shall prevail.

Code M

• It is usually called centrally at the end of a program segment to trigger auxiliary actions sequentially.
• Part of the M code needs to be combined with other instructions,such as M03 requiring S to specify speed.

4.Differences in programming tools

G Code Programming

• Manual programming: Reliance on engineer experience for simple tasks.
• CAM software generation: For example, Mastercam and UG NX automatically generate G-code.

M Code Programming

• Standardized calling: Most M-code is pre-set by machine tool manufacturers and does not require customization.
• Special Feature Expansion: Some high-end machine tools allow customization of M code (such as integrated visualization checks).

How can JS shorten the delivery cycle of complex components?

1.Five-axis linkage machining: Reduce the number of clamping times (one clamping can complete multi-faceted machining), avoid multiple positioning errors, improve processing efficiency by 30%-50%.

2.High-speed cutting technology: Tool speed can reach tens of thousands of rpm, cemented carbide processing speed is 2-3 times higher than traditional cutting methods, while maintaining accuracy of ±0.005mm.

3.Integrated lathe, milling: The integrated machine set lathe, milling, drilling and other functions in one, so that the turbine discs and other rotary parts machining time reduced by more than 40%.

4.Hybrid manufacturing model: 3D printing, CNC precision machining for rapid prototyping of complex structures (e.g. hollow lattices) requires about athird of the time of traditional processes, typically with a 50% reduction in the lead time for delivery of aerospace components.

5.Intelligent production scheduling system: Automatic optimization of tool paths and equipment loads, 25% increase in resource utilization when multiple orders are produced in parallel, and 48 hours increase in emergency order insertion response time.

Summary

In the modern industrial system, CNC machining technology has developed from a traditional tool to a core engine of manufacturing innovation. From the initial coordinate control to today's intelligent decision-making, the technology has evolved to cover machining mill, machining lathe, multi axis linkage processing such as multi dimensional manufacturing ecosystem. Its core value lies not only in the industrial reproduction of micrometer level precision, but also in the construction of collaborative innovation paradigm of material process design.

JS company is a benchmark practitioner in this area. By means of five-axis coupling technology, the error tolerance in the design and production of complex curved parts is realized. Under the synergy of lathe compound manufacturing and additive manufacturing, the material and structure limitation of traditional process is broken, and the production efficiency is raised to a new heights by automatic closed-loop control system.
