Precision Performance for Critical Applications

The Atlanta Helical Rack guarantees exceptional accuracy in motion control, thanks to its advanced manufacturing tolerances and induction-hardened surface. Its helical groove design ensures quieter and smoother operation, crucial for CNC routers, milling machines, and automated gantry systems in demanding industrial environments.

Engineered for Versatility and Reliability

Suitable for both heavy-duty and high-speed applications, this gear rack supports numerous industrial sectors. Whether you require reliable performance under dynamic loading or need seamless integration with robotics and power transmission setups, this racks robust alloy steel construction adapts to varied operational needs.

FAQs of Atlanta Helical Rack:

Q: How is the Atlanta Helical Rack installed, and what mounting options are available?

A: The rack is provided with precisely drilled and counterbored mounting holes, making installation straightforward on machines such as CNC routers, milling machines, and gantry systems. The number and pattern of mounting holes are determined by the gear racks length and module to ensure secure and accurate alignment.

Q: What makes the Atlanta Helical Rack suitable for high-precision and high-speed applications?

A: This helical gear rack boasts a pitch error per meter of 0.05 mm and a tolerance of 0.05 mm, ensuring consistently accurate motion control. Its robust alloy steel build and induction-hardened, precision-ground surface enable fast cutting speeds (up to 80 m/min) and high spindle speeds (up to 3000 rpm), making it optimal for CNC and automation systems.

Q: Where can the Atlanta Helical Rack be used, and what industries benefit most?

A: The rack is designed for use in CNC machinery, industrial automation, robotics, and gantry systems. Its versatility makes it an excellent choice for manufacturing sectors requiring high precision, such as automotive, aerospace, electronics, and fabrication industries.

Q: What processes and treatments give the rack its durability and corrosion resistance?

A: The alloy steel rack undergoes induction hardening for superior wear resistance. Its surface is finished with black oxide coating and a rust-protective layer, then packed in sturdy wooden cases for secure transit and storage.

Q: How does the rack benefit end-users in terms of operational efficiency?

A: By offering high load-bearing capacity, reduced backlash due to helical tooth design, and long service life from quality hardening processes, the rack minimizes maintenance needs and ensures smooth motion, driving productivity in power transmission and automation tasks.

Q: When should this gear rack be chosen over straight tooth racks?

A: Select the Atlanta Helical Rack when your application demands quieter operation, higher load capacity, and better positional accuracyespecially important in rapid, precise movements within CNC, robotic, and gantry systems.
