Beach sand drilling machine test machine DR-1389

The automatic drill machine control system for rackets adopts a 5-axis computer control system. The control system can directly import the drilling dimensions of the racket. Each type of racket can have a processing document created. When changing the processed product, there is no need to change the mold; only the processing document needs to be replaced to meet the current processing requirements of the racket. The racket clamping fixture developed by our company is simple to operate and has good positioning. It only takes 1-2 seconds to complete the clamping action by placing the racket into the fixture. One machine can process 5 beach rackets simultaneously, and one worker can operate 3-4 machines, which can save a lot of labor. The drilling motor uses a high-speed motor with a maximum speed of up to 24,000 rpm to ensure that there are no burrs in the inner holes of the racket. The downward speed of the drill bit is automatically adjusted by the controller. When the drill bit is close to the racket, the speed slows down to ensure that the racket surface does not lose paint or water marks. Once the drill bit head enters the racket, the speed increases to improve the drilling efficiency.

Product Features

1. High efficiency: The average processing time for each piece is approximately 60-70 seconds (if a double-head machine is customized, the processing time is halved). The racket picking and placing is simple and can be completed in about 5 seconds. This machine is fully automatic and one person can operate and manage 3-4 units simultaneously. ,

2. High precision: Positioning accuracy of 0.02-0.1mm (equivalent to a maximum deviation of only one hair's width);

3. Simple operation: Just press the start button, and the machine will automatically complete the processing with low labor intensity;

4. Simple file editing: The human-machine interface imports instructions, and different racket programs can be numbered and archived;

5. Strong interchangeability: When changing racket models, simply replace the corresponding fixture, and the fixation is very simple;

6. It has an automatic tool setting function, eliminating the need to spend a lot of time adjusting and aligning the mold;

7. Application fields: Suitable for drilling and milling processing of various fiber badminton rackets, tennis rackets, squash rackets, etc. 

Relevant parameters

Core Functions

Multi-scenario Drilling Performance Testing

1. Tensile Strength Test: Tensile force range 0~10kN (accuracy ±0.5% FS), simulating the force on the drilling area of the racket frame during hitting or collision, to detect the maximum tensile force (≥5kN is excellent) and failure mode (hole wall tear/ adhesive layer peeling).

2. Salt Spray Corrosion Test: Simulating marine environment according to ASTM B117 standard (salt spray deposition rate 1~3mL/80cm²/h), continuous testing for 24~1000 hours, to verify the anti-rust performance of the coating at the drilling edge.

Dynamic Fatigue and Precision Verification

1. High-frequency Vibration Test: Frequency 1~50Hz (sine wave/random wave), acceleration 0~30g, simulating the vibration impact during long-term use, to detect the micro-crack propagation and hole diameter deformation at the drilling edge (accuracy ±0.01mm).

2. Drilling Precision Analysis: Using a laser scanner (±0.005mm) to detect the roundness of the hole diameter, position deviation (≤±0.1mm), and inner wall roughness (Ra≤3.2μm).

Intelligent Monitoring System

1. Real-time Multi-parameter Acquisition:

✦ Tensile force, torque (±0.5% FS), temperature (infrared thermal imager ±1℃), vibration spectrum (5~5000Hz).

✦ High-speed camera (5000fps) captures the stress concentration and crack initiation process at the drilling edge, generating a 3D model for failure analysis cloud map.

2. AI Failure Analysis: Machine learning algorithms analyze corrosion rate and vibration fatigue data to predict the drilling life and recommend coating optimization solutions (such as nano-ceramic coating).

3. Data Traceability: One-click generation of PDF/Excel reports (including S-N curve, salt spray corrosion grade), supporting MES system integration and production batch traceability. 

Technical Highlights
