1.Qier Machine Tool Group Co., Ltd
(A) Company introduction: One of the 3 most famous Chinese Machine Tool manufacturer
(B) Applied workpiece: machine tool body, column, and slide
(C) Effect:It is hard to treat some big size work piece by thermal furnace. It can not treat some complicated structure work piece by sub-resonance Vibratory stress relieving. After using our Vibratory stress relieving, these problems were solved, and work efficiency was improved.
2.Spark Machine Tool Co.,Ltd
(A) Company introduction: A reputable and leading manufacturer of super heavy duty lathe and CNC lathe
(B) Applied workpiece: machine tool body, workrest, column, and slide
(C) Effect:For the machine tool bed, technical deformation of straightness is within 0.11mm, and 2 times vibration stress relief before finish machining. After the 1 time of harmonic frequency spectrum Vibratory stress relieving , the straightness is 0.07mm, which satisfy technical requirement. Fully applied to other machine tool parts which need to relieve stress
3.Bright World Precision Machinery Limited
(A) Company introduction: A reputable and professional manufacturer of forging machines in the industry.
(B) Applied workpiece: machine tool body of forging machines
(C) Effect:Place the workpiece for 2 months and measure the dimension stability. The requirement for a casting is within 0.05mm, for a weldment is within 0.1mm. and after vibratory stress relieving, satisfy the above requirement. For some workpiece weighted above 30Tons can be treated on the spot, not to transport to other plants to do the stress relief, which saved a lot of time & money.
4.Yibin push-ningjiang Machine tool development Co.,Ltd
(A) Company introduction: It is specialized in manufactures of big CNC
(B) Applied workpiece: machine tool slide & body
(C) Effect:Adopt of Method of Metal magnetic memory to detect the stress distribution between before and after the vibratory stress relieving. The average decrease rate for a slide is 40.57%, for a bed is 48.5%, refer to below chart
