The second batch of 300 pieces had an M2.5 core hole that was made too large, making it impossible to secure the screws and rendering the product unusable by the customer.
The problem was caused by a failure to remove slag during the tapping process. The slag enlarged the threaded hole, making rework impossible.
We will redo 150 pieces at no cost to the customer.
Dear Allison,
Thanks for your delivery the goods surface looks visual very nice.
All dimension are good except on the part «Kalibrierring MONOline IR Elchem».
The core hole of the M2.5 thread is too big, so the screw's can be fixed.
The core hole of the M2.5 thread should be 2.05 (or 2.10 is okay) but it is nearly 2.5mm. (attached photo).
Dear **,
I apologize our checking the cause may be tapping did not blow slag in time, slag to screw thread hole squeezed big. If future repeat orders, we will pay more attention to avoid this happening again.
Please help to double check if all 300pcs M2.5 Core holes too big?
Our solution as below:
A: Would you consider using M3 screw to fixed? It will affect your usage? (If extra cost is incurred, please let us know in advance, REKO can take it.)
B: REKO can remake, about 10-15 working days.
Please let us know would you consider A or B?
Dear Allison,
If we choose option B, what should we do with the 300 pieces we have here? We also have to produce and have to start reworking and using them. We would also like to point out that we do not want to have any costs if we choose option B.
I look forward to hearing from you ASAP.
Dear **,
Option B- REKO remake the 300PCS, you don't need to pay for the parts and don't need t pay for the freight.
Can you wait for 10-15 days? ( Oct.1 to 7 is National Day Holiday ). When do you expect to receive the new ones, see how we can do for you.
Let us know if you have any other suggetions?
By the way, attached FYI .→
lf it is REKO's responsibility, REKO will underatake all the cost.
lf it is client's responsibility, REKO will try to find a way to reduce the cost that make loss as less as possible.
Dear Allison,
Thank you very much for your fast response and the solution you are offering. We really appreciate it.
The drawing is fine. Please just note that your production works accurately during manufacturing and the threads size are made according to the mail from Mr. *.
Please be informed that we will only need 150. This will cover our time investment and reduce your costs. I hope that is fine with you.
Thank you for your attention and have a nice day.
