Complex Surface Machining

1. Applicable Products and Processing Requirements

Complex surface machining is widely used in fields such as 3C electronics (e.g., curved surfaces of mobile phone frames and smartwatch cases), medical devices (e.g., curved surfaces of artificial joints), and automotive interiors (e.g., curved structures of instrument panels). The core requirements are: High surface contour accuracy (error ≤ 0.005 mm), excellent surface finish (Ra ≤ 0.8 μm), and smooth transitions between multiple curved surfaces. Moreover, it is necessary to avoid issues such as “overcutting” and “undercutting” during the machining process.

2. Dike Device Compatibility and Technical Advantages

(1) TL Series Drilling and Tapping Machine: Efficient Machining of Medium- and Small-Sized Complex Surfaces

• Core compatible models TL740/TL800 (Large stroke + high-speed spindle, suitable for medium- and small-sized curved parts)

• Technical Support ：

◦ Equipped with Dike-CNC Intelligent CNC System It supports “five-axis linkage simulation functionality,” enabling you to preview the surface machining path in advance. Combined with real-time error compensation technology, it dynamically corrects spindle runout deviations, ensuring that the surface contour accuracy is controlled within ±0.005 mm.

◦ The spindle’s maximum speed is 24,000 rpm, and when paired with a high-rigidity tool holder, the vibration during cutting is ≤0.002 mm, ensuring that the surface finish of curved surfaces reaches Ra ≤ 0.4 μm without the need for subsequent polishing.

◦ The rapid traverse speeds for the X/Y/Z axes are 60/60/50 m/min, increasing machining efficiency at curved surface transitions by 30% and eliminating “step marks” caused by uneven feed rates.

(2) VL Series Vertical Machining Centers: Precision Machining of Medium- to Large-Sized Complex Surfaces

• Core compatible models VL1165 (Ultra-large stroke + high rigidity for heavy cutting, suitable for medium- and large-sized curved parts)

• Technical Support ：

◦ Adopt Grating scale closed-loop control Repositioning accuracy: ±0.002 mm; X/Y/Z axis travel: 1100×650×600 mm. This machine is capable of machining medium- and large-sized curved parts, such as automotive bumper molds and medical device housings.

◦ Optional Four-axis linkage module By enabling coordinated machining of “linear axes + rotary axes,” the processing efficiency for irregular surfaces (such as 3D glass hot-bending molds for mobile phones) is improved by 45% compared to conventional equipment.

◦ Equipped with High-pressure internal cooling system (pressure up to 70 bar) It can instantly flush away chips generated during surface machining, preventing the chips from scratching the machined surface and ensuring the smoothness of the curved surface.

3. Customer Cases

A Shenzhen-based 3C electronics company uses the TL740 drilling and tapping machine to machine the curved surfaces of mobile phone frames (material: 6061 aluminum alloy). After machining, the surface profile error is consistently within ±0.002 mm, and the surface finish reaches Ra = 0.4 μm. Production efficiency has improved by 32% compared to the previous equipment, while the defect rate has dropped from 5% to 0.8%, achieving “zero rework in mass production.”

Other solutions

Aerospace

Aerospace product manufacturing encompasses components such as structural parts (e.g., aircraft fuselage frames, satellite supports) and precision parts (e.g., engine valve cores, navigation instrument housings). The core requirements include: extremely high machining accuracy (with errors no greater than 0.003 mm), robust equipment operational stability (capable of continuous operation for 72 hours without failure), excellent part traceability, and compliance with international standards such as AS9100 (the aerospace quality management system).

Car

Automotive parts processing encompasses components such as structural parts (e.g., engine cylinder blocks, chassis brackets), transmission components (e.g., gearbox gears), and interior components (e.g., dashboard brackets). The core requirements are: high batch-processing efficiency (single-shift capacity ≥ 500 units), tight dimensional consistency (tolerance ≤ 0.01 mm), low equipment failure rate (overall equipment effectiveness OEE ≥ 90%), and the ability to accommodate flexible production needs for "multiple varieties in small batches."

Mold

Mold manufacturing covers areas such as plastic molds (e.g., housings for home appliances), stamping dies (e.g., automotive sheet-metal molds), and die-casting molds (e.g., middle frames for mobile phones). The core requirements are: high precision of mold cavities (tolerance ≤ 0.005 mm), excellent surface finish (Ra ≤ 0.4 μm), and high processing efficiency (shortening the mold delivery cycle). Additionally, it is crucial to avoid “mold trial failures” caused by machining errors.
