WHAT OUR CLIENTS SAY
Deliver good machines, enjoy good life
In the fall of 2024, I ordered a CNC bandsaw machine from Shanghai ANTS Machine Equipment Co., LTD to be used in our handrail production factory. I can confidently verify the exceptional quality and functionality of this machine. It has proven to be a valuable addition to our production process. The professionalism of their sales, service and support team—especially Baccata—has been superb and greatly appreciated.
Because of my 100% satisfaction with this experience, I have recently purchased a CK6150 CNC Lathe from them and am already looking to purchase more equipment in the near future.
USA Bobby Kelly Purchase manager
We ordered three sets of machines from Shanghai ANTS Machine Equipment Co.,LTD to use for our production in 2021. Two sets of double columns gantry horizontal saw machine and one turret milling machine During testing, the machines were found to have 100% same performance dimensions as our request. These machines are working as expected ever since, without any problems.
Thank you for providing us with such reliable equipment and service support. We are looking forward to ANTISHI’s long-term cooperation.
