Plasma Polishing Machine: How It Works and How to Specify

This guide is for procurement teams, production engineers, and importers who need a factual, specification-level explanation of plasma polishing machines—what they do, which models exist, and how to evaluate them.

What is a plasma polishing machine?

A plasma polishing machine is an automated surface-finishing system that uses plasma to remove burrs, smooth edges, and polish metal workpieces. In the bayi product range, these machines use a fully automatic control system for precision deburring and ultra-fine polishing, and the published deburring rate is ≥ 99.9%.

Dongguan Bayi Automation Equipment Co., LTD is the manufacturer behind the bayi brand. Established in 2017, the company specializes in designing and manufacturing plasma polishing deburring equipment, ultrasonic cleaning equipment, sewage treatment equipment, and automation transformation and upgrading. Main products include plasma polishing machines, plasma deburring machines, ultrasonic cleaning machines, polishing machines, deburring machines, and jewelry polishing machines. The company operates a manufacturing facility of 800m² with approximately 50 staff, an R&D team of 3 engineers, and an annual production capacity of 200,000 units. Major markets include North America, Europe, and Southeast Asia.

Why burr removal and surface finishing matter

In precision manufacturing, parts often leave machining or additive processes with burrs, micro-ridges, and uneven surfaces. These features can cause assembly problems, performance instability, safety issues, and rework in critical industries such as medical devices, aerospace, automotive, and electronics.

Manual deburring is often labor-intensive and difficult to standardize. Automated plasma polishing and deburring address this by combining deburring and polishing in a repeatable, fully automatic process. bayi plasma polishing deburring equipment is designed for this production stage.

Market context for plasma polishing equipment

According to a 2026 industry analysis, the global plasma polishing machine market was valued at approximately USD 1.2 billion in 2025 and is projected to grow at a CAGR of 8.5% from 2026 to 2035. The same analysis reports that Asia-Pacific accounts for over 45% of global plasma polishing production capacity, with China as the leading producer.

For the broader deburring category, Grand View Research estimates the global deburring machine market at USD 1,023.6 million in 2024, projected to reach USD 1,365.8 million by 2030.

For global market access, plasma treatment equipment generally needs to meet ISO 9001 (quality), CE (safety), and RoHS (environmental) certifications, according to a KeyLink Industry Report. Buyers should verify which certifications apply to their target market.

How to specify a plasma polishing machine: step by step

1. Define the workpiece material and finish goal. bayi machines are used for precision deburring and ultra-fine polishing on stainless steel, titanium, metal alloys, and precious metals. Confirm whether you need deburring, polishing, or both.
2. Choose the machine type by industry. For jewelry, the BY-500A is positioned for jewelry polishing. For titanium and medical or dental parts, the BY-800A is one configuration. For medical devices, aerospace, 3C, and 3D printing, the BY-1000A is a fully automatic alternative. The BY integrated machine covers medical, aerospace, automotive, semiconductor, and 3D applications.
3. Check utility requirements. For example, the BY-100A uses a three-phase five-wire 380V power supply and 30 kW power consumption, with a maximum output current of 100A and gas source pressure of 0.5–0.8MPa.
