The “1-day delivery” service of lkprototype CNC has compressed the traditional CNC processing cycle from 5 to 7 days to within 24 hours through a fully automated process and intelligent production scheduling system, while maintaining an accuracy of ± 0.01mm. Using the processing of the middle frame made of 6061 aluminum alloy on the mobile phone as an example, one piece takes only 3.5 hours to process (18 hours for traditional processing). Through the use of the 5-axis linkage machining center (rotating speed of 24,000 RPM) and the AI path optimization algorithm, the material removal rate has been improved to 98 cm³/min (industry average: 60 cm³/min). For one consumer electronics purchaser in 2023, a last-minute order had 200 samples delivered from the drawings in 14 hours, shaving 80% off the products’ lead time.
As for material flexibility, the lkprototype CNC supports rapid processing of 38 varieties of engineering plastics and metals such as titanium alloy and PEEK. A medical device project used TC4 titanium alloy (hardness HRC 36) to make the prototype of the surgical forceps. From importing the 3D model to the post-treatment (surface Ra 0.8 μm), it was just 22 hours, which was four times quicker than others. Its multi-axis synchronous processing technology (B-axis ±120° rotation) reduces the clamping times of complicated curved surface parts from 7 times to 1 time, increasing the processing efficiency by 300%. A verification of a certain automotive turbine blade project shows that the cost per piece is saved by 35% (from 420 yuan to 273 yuan).
The quality assurance system ensures that the quality will not be reduced at high speed. lkprototype CNC’s computer-aided inspection system (with CMM accuracy of 0.005mm) monitors key dimensions in real time. The first-pass rate of one specific aerospace connector project (tolerance ± 0.015mm) was up to 99.3% (industry average: 92%), and the rework rate was reduced to 0.2%. The ±1°C at 20°C temperature-controlled workshop and the ±5 minute error tool life predicting model work together to improve the stability of the processing by 40%. A particular optical lens mold contour error is regulated to 0.008mm (customer demand ≤ 0.02mm).
The highest speed used in testing the capability of ultra-urgency orders. With the distributed manufacturing network (8 intelligent factories around the world), the lkprototype CNC can start cross-time zone collaborative manufacturing within 4 hours. The high-precision gearbox of a particular European customer (module 0.5, tooth profile error ≤ 0.01mm) was produced by a Sino-German factory in relay mode. From ordering to international express delivery, it only took 18 hours, which saved 62% of the time taken by local production. Its intelligent logistics system (transport speed of AGVs 1.5m/s) also reduces the in-factory circulation time to 8 minutes (45 minutes in traditional mode).
Cost-benefit analysis shows competitiveness. In prototype orders of 100 pieces or less, lkprototype CNC unit price is 120% of industry average. But taking into account the total time cost, the customers’ total expense is reduced by 55% (estimated on the basis of engineer charges with a compression of 5 days in the R&D stage and a 2,000 yuan daily wage). One unmanned aerial vehicle enterprise brought the iteration cycle down from 7 days by version to 1 day using its services and lowered research and development expenditures over 800,000 yuan within the first year.
Actual scenarios confirm reliability. 316L stainless steel CNC+ polishing 2023 smartwatch project was completed within 14 hours at lkprototype CNC (customarily taking 3 days), with a surface processing leading to a MI 0.02 grade mirror finish. Its “same-day delivery” service has fulfilled 85% of domestic orders. The 2024 customer survey states that the level of satisfaction in emergency demand is 98.7%, with median deviation in precision as low as 0.007mm, setting a new speed record for rapid prototyping manufacturing.
