GPM-2-300 Spectrum Grinding Machine

‌GPM-2-300 Spectrum Polisher: One Machine for Grinding, Polishing & Automation‌‌

Why buy separate grinders and polishers? The GPM-2-300 handles ‌grinding, pre-polishing, and finishing‌ in one rugged 122kg system. With stepless speed (100–1400 RPM) and a brushless DC motor, it’s the Swiss Army knife of metallography – ideal for labs automating workflows or tackling complex materials like composites and superalloys.

‌Key Features‌

• ‌Automation-Ready Speeds‌: Stepless RPM control or 4 preset speeds (300/600/900/1400) – sync with robotic arms for 24/7 runs.
• ‌Zero Dust, Zero Fuss‌: Built-in collector traps 99% of debris – meets OSHA and ISO 14001 standards.
• ‌Power Without Noise‌: 1.1kW brushless motor runs quieter than hydraulic systems (≤65dB).
• ‌Swap Abrasives in Seconds‌: Magnetic 300mm disc holds papers/pads without adhesives.
• ‌Spray-Coated Durability‌: Stain-resistant frame survives acids, coolants, and heavy daily use.

‌Why Automate with GPM-2-300?‌

• ‌All-in-One Efficiency‌: Replace 2–3 machines – save floor space and maintenance costs.
• ‌Future-Proof Flexibility‌: Handle everything from rough grinding to mirror finishes in one workflow.
• ‌Green Compliance‌: Low energy use and dust collection boost sustainability metrics.

  In the process of preparation of metallographic sample, pre grinding, polishing and grinding are the indispensable procedures, which are usually finished by the grinding and polishing machine. However, for some rough work pieces, they should be finished by some special machines. According to the different kinds of requirements of the customer, our company designs GPM-2-300 spectrum grinding machine, which has novel and beautiful appearance, and the whole frame adopts spray process. The machine is very easy to use and the abrasive paper is also convenient to be replaced. It saves time and avoids wasting. There is an internal dust collecting device, makes it safety and environmental protective. This machine starts steady and has large transmission power and low noise. This machine can be adapted to various materials preparation of test samples, improves the quality and efficiency of the grinding and polishing, which is the best equipment of metallographic sample preparation.
