CHMAC pitches V-grooving machines for tight-tolerance fabrication

CHMAC is highlighting its V-grooving machines as a fix for fabricators that need sharp corners, low deformation and consistent folds in high-end sheet metal work. The company says the machines support precision projects across architecture, industrial cabinets and other applications, with ISO9001 and CE certifications backing the product line.

Why it matters: - Tight-tolerance sheet metal work often fails when standard bending leaves visible radii or material distortion. - CHMAC is targeting fabricators that need crisp corners and repeatable folds for architectural metalwork, industrial enclosures and premium consumer products. - The company positions V-grooving as a way to reduce waste, improve consistency and support more automated production.

What happened: - Jiangsu Chuangheng Machinery Technology Co., Ltd. (CHMAC) promoted its V-grooving machines as a solution for precision fabrication. - The company framed the technology as a way to close the “Precision Gap” in high-end sheet metal work. - CHMAC pointed to applications in stainless steel decorative pillars, communication cabinets, elevator interiors, kitchenware, smart home appliances and other tight-tolerance projects. - The company published more information on its official website: More information

The details: - Standard press-brake bending typically produces an outer corner radius of about 1 to 1.5 times the material thickness. - CHMAC says its V-grooving process cuts a precise V-shaped groove before folding, which allows a tighter, near-zero-radius corner. - The machines use high-rigidity frames and advanced servo-control systems. - A hydraulic clamping system and independent pressure foot help hold non-flat sheet metal against a precision-ground alloy steel worktable. - CHMAC says the cutting head maintains uniform groove depth from start to finish. - Four-cutter technology spreads the cutting load across multiple alloy blades. - The multi-blade setup reduces heat buildup and tool wear and helps produce a clean, burr-free finish. - The machines are designed for mirror-finish stainless steel and coated aluminum, including parts for communication cabinets and electronic power housings. - The software accepts material type, thickness and target angle, then calculates the cutting path and depth automatically. - CHMAC says the system reduces trial-and-error and cuts material waste. - The equipment is designed to work with CNC press brakes and laser cutting systems. - CHMAC says the machines support flexible production lines and non-standard automatic units with less downtime. - The company says the equipment is efficient, intelligent and environmentally friendly. - CHMAC says the machines serve auto parts, communication cabinets, smart home devices and bathroom sheet metal applications. - CHMAC says the products hold ISO9001 quality management system certification and EU CE certification.

Between the lines: - The pitch is aimed at fabricators competing on finish quality as much as throughput. - The emphasis on automation, reduced waste and system integration suggests CHMAC is selling a workflow upgrade, not just a standalone machine. - The certification and Industry 4.0 language are meant to reassure buyers making capital equipment decisions for long production cycles.

What's next: - CHMAC expects precision V-grooving to become more important as intelligent manufacturing expands. - The company is betting that demand will keep rising for custom, small-batch and high-complexity sheet metal orders. - Fabricators seeking more information can review the company’s product materials on its website.
