PW-1B Multifunctional Grinding And Polishing Machinery with Grinding Head

 ‌PW-1B Grinder & Polisher – Your Lab’s Swiss Army Knife (From Rocks to Mirror Finishes)‌
‌Why clutter your lab with 3 machines when the PW-1B does ‌grinding, polishing, and prep‌ in one compact unit? Crank it to ‌1400 RPM‌ to blast through steel slag, then dial down to ‌200 RPM‌ for delicate glass polishing – all with a twist of the knob. The ‌frequency conversion motor‌ (220V) and ‌stainless steel tray‌ handle ceramics, minerals, and alloys without breaking a sweat. Perfect for labs that juggle geology, metallurgy, and materials science.

‌Key Features ‌

• ‌One Machine, Five Jobs‌: Grind (wet/dry), polish, prep rocks, ceramics, metals.
• ‌Infinite Speed Control‌: 50 RPM (delicate glass) to 1400 RPM (aggressive steel grinding).
• ‌Lab Whisperer‌: Quieter than a conversation (65dB) – focus without ear protection.
• ‌Stainless Steel Everything‌: Spill-proof, rust-proof, chemical-proof.
• ‌Compact Powerhouse‌: 85kg, 700mm width – fits small labs or crowded workshops.

‌Why PW-1B Stands Out‌

• ‌No Cross-Contamination‌: Dedicated discs for grinding vs. polishing.
• ‌220V Flexibility‌: Works in regions with lower voltage infrastructure.
• ‌Zero Downtime‌: Swap between tasks faster than brewing coffee.

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.
