China Metal Shrinking Machine Manufacturers, Suppliers, Factory

The Chinese manufacturer JM has the most types of V grooving machines in China, the CNC horizontal high speed v groove slotting machine from it is a professional and cost-effectiveness V grooving equipment.

High quality Vertical V Grooving Machine with Two Head is offered by China manufacturer JM. Grooving machine is highly effective in precision work and corner bending to maintain edges. By using V grooving machine which is stable to bend metal sheets, they can be folded into tight, seamless workpieces.

JM is a professional leader China Automatic Four Side CNC V Grooving Machine manufacturer with high quality and reasonable price. A metal sheet v grooving machine can create V-shaped grooves in stainless steel sheets, aluminum sheets, composite aluminum sheets, copper sheets, and other metal plates. Four side v grooving machine realize the horizontal grooving of the plate. This allows the bent workpieces to have a very small edge radius, meeting the high precision and aesthetic demands of the high-end sheet metal decoration industry. JIANMENG provides various solutions, making metal fabrication easier!

JIANMENG Laser Cutting Machine integrates high-precision laser cutting, intelligent V-grooving, and fully automated production into one system, enabling one-stop processing from flat sheet to finished workpiece. V Grooving & Laser Integrated Machine achieves positioning accuracy of up to ±0.1 mm, delivering smooth, burr-free, deformation-free edges, and is capable of machining complex irregular shapes and sharp, reflection-free bends. Vertical Laser & V Cutting Machine intelligent control system connects directly to engineering drawings, automatically completing cutting path planning, process parameter matching, and continuous whole-sheet processing. Compared with traditional multi-machine, step-by-step workflows,V Grooving & Laser Integrated Machine boosts efficiency by more than three times, reduces process changeover time by over 80%, and ensures top-tier standards in dimensional accuracy, surface quality, and design complexity—making it the ideal choice for high-end architectural decoration and artistic installations.
