PW-1B Multifunctional Metallographic Grinder – From Rocks to Metals, One Machine Does It All
Why juggle separate machines for rocks, metals, or ceramics? The PW-1B combines stepless speed control (50–1400 RPM) with a stainless steel sewage system to handle any material – granite, titanium, glass, or alloys. Perfect for geology labs, metallurgy workshops, or R&D centers needing hybrid sample prep. CE-certified, 220V-ready, ships in 5–8 days.
Key Features
-
Multi-Material Master: Grind rocks (200 RPM), polish steel (1000 RPM), or prep ceramics (600 RPM) – no machine swaps.
-
Stepless Speed Dial: Fine-tune RPM for exact material requirements (50–1400).
-
Stainless Steel Armor: Resists abrasives, acids, and water – zero corrosion.
-
BY80 Frequency Motor: 220V, 0–50Hz – 30% more energy-efficient than brushed motors.
-
Lab-Grade Quiet: ≤65dB – ideal for shared workspaces.

Why This Machine Wins
-
Hybrid Labs: Eliminates separate rock/metal grinders – cuts equipment costs by 50%.
-
Precision = Speed: Dial in RPMs to match material hardness (e.g., 300 RPM for soft glass, 1200 RPM for hardened steel).
-
Zero Rust: Stainless steel base survives wet grinding, chemical cleaning, and high humidity.

PW-1B multifunctional grinding and polishing machine is used for the grinding and polishing of lithofacies specimen and metallographic sample. No matter the sample materials of rock, mineral, ceramics, glass, ferrous metal and other silicate, it is extremely adaptable to coarse grinding, oil grinding, dry grinding, wet grinding, grinding and polishing, etc. The machine rotates steadily with low noise and has automatic grinding head, the rotating speed can be regulated stepless in the range of 50~1400r/min. The sewage collection disc and cover are made of stainless steel, which can endure long time and is easy to maintain. Therefore it is the ideal equipment for metallographic sample preparation.
