Industrial CNC Engraving Machine | 29-Yr Precision & Global Support

Precision CNC Brass Engraving – Sharp Details, No Burrs

We provide CNC brass engraving solutions using our fiber laser engravers. Brass is reflective but our laser source has anti‑reflection protection, ensuring stable processing. Achieve fine text (0.5mm height) and complex graphics on brass plates, badges, instrument panels, and decorative items. Our CNC brass engraving process creates permanent, corrosion‑resistant marks with high contrast. No tool wear or mechanical stress, unlike rotary engraving. We also offer rotary attachments for engraving around cylindrical brass parts like valves and fittings. The software allows easy import of logos and serial numbers. CNC brass engraving from Tianchen Laser is fast (0.2 seconds per character) and cost‑effective.

Advantages of the product

Global Service Network in Over 100 Countries

Backed by Tianchen Laser’s international presence, every CNC engraving machine comes with worldwide service support. We have established service centers and trained technicians across more than 100 countries and regions, ensuring rapid response to technical inquiries, spare parts delivery, and on-site maintenance. The average response time for critical issues is under 24 hours in major industrial zones. Our global parts warehouse stocks all common wear parts such as spindles, collets, drive belts, and circuit boards, so you never face prolonged downtime. Additionally, we provide multilingual online support, video troubleshooting, and remote software updates. This global network is not just a promise—it is a proven infrastructure built over 29 years of exporting heavy machinery. Choosing our CNC engraving machine means you are never alone; you have a partner that understands local regulations, power requirements, and language barriers.

High-Speed Engraving with Industrial-Grade Spindle

The core of any CNC engraving machine is its spindle, and our units are equipped with high-torque, liquid-cooled industrial spindles ranging from 1.5kW to 7.5kW. These spindles achieve speeds up to 24,000 RPM with runout accuracy below 0.005mm, allowing clean edges and fine details even on hardened steel or granite. The thermal stability of the liquid cooling system ensures consistent performance during 24/7 operation. Paired with a rigid linear guideway and ball screw transmission, our machine maintains high feed rates without sacrificing precision. You can engrave at speeds up to 15m/min while holding tolerances of ±0.01mm. This combination of speed and accuracy directly improves your production efficiency—whether you are marking serial numbers on automotive parts, engraving decorative panels, or producing metal stamps. The spindle’s dust-proof design and automatic lubrication further extend service life beyond 10,000 working hours.

For more than 29 years, focused innovation in intelligent metal forming solutions has built a strong manufacturing system with an annual core equipment output of over 10,000 units, serving customers in more than 100 countries worldwide. CNC brass engraving represents a high-precision processing technology specifically optimized for brass materials, which are widely used in hardware, decoration, electronics, automotive connectors, and craft products. Brass features good ductility and electrical conductivity but requires gentle, high-precision processing to avoid deformation, burrs, or surface oxidation. The CNC-controlled engraving system uses a high-stability laser source and precision path control to achieve non-contact, low-heat-impact engraving on brass sheets, tubes, and shaped parts. It can create fine patterns, characters, logos, textures, and depth markings while maintaining the original metallic luster and structural integrity. In decorative hardware, it produces exquisite engravings on faucets, door handles, and decorative panels; in the electronics industry, it marks permanent codes on brass connectors to ensure product traceability; in musical instrument and craft manufacturing, it adds artistic patterns to enhance product value. The CNC system ensures high path accuracy, uniform engraving depth, and high repeatability, supporting batch processing with consistent quality. It supports graphic design import from mainstream software and allows flexible parameter adjustment for different brass thicknesses and surface treatments. The processing efficiency is high, with low tool loss and low maintenance costs. Customized engraving solutions are available according to product shape, processing area, pattern complexity, and production volume. The stable and reliable processing quality makes it suitable for long-term industrial production.

Common problem

What is the typical delivery time for a CNC engraving machine?

Standard models of our CNC engraving machine are typically delivered within 15-30 days after order confirmation. Customized machines with special table sizes or spindle options require 4-6 weeks. We have warehouses in Asia, Europe, and North America to reduce shipping time. Expedited shipping options are available for urgent projects.

What power supply requirements does the CNC engraving machine need?

The standard CNC engraving machine operates on 220V single-phase or 380V three-phase power, 50/60Hz, depending on the spindle size and servo drives. We also offer customized voltage options (110V, 480V) for specific countries. Each machine includes a surge protector and emergency stop system. Our technical team will confirm your local power specifications before shipment.

Does the CNC engraving machine come with a warranty?

Yes, every CNC engraving machine from Tianchen Laser includes a 24-month standard warranty covering all mechanical and electrical components. The spindle and servo motors have a separate 36-month warranty. We also offer extended warranty plans up to 5 years. Global service centers handle warranty claims quickly, and we keep spare parts for at least 10 years after model discontinuation.

Great value for small business

As a small sign-making business, I was hesitant to invest in a large machine. The compact 300x400mm CNC engraving machine from Tianchen exceeded my expectations. It engraves acrylic and aluminum sheets with zero burrs. The software was easy to learn, and the video tutorials covered everything from tool calibration to 3D carving. After one year, no breakdowns. The energy-saving mode cut my electricity bill by 25%. Excellent purchase.

Global parts availability is a lifesaver

When our CNC engraving machine’s drive belt broke after 14 months (normal wear), I was worried about downtime. Tianchen’s local distributor in Brazil had the belt in stock and delivered it next day. The online manual showed the replacement procedure in 15 minutes. This level of global support is rare. The machine itself continues to perform perfectly for our furniture engraving needs.
