TCD Floor Grinding Disc Chinese invention patent no.: 200910111334.5 International invention patent no.: PCT/CN09/07085 As the quality of natural diamond 6# is not stable all over the world, so we developed the new technology TCD. ASHINE is the No. 1 in the world to use TCD-technology for concrete floor grinding, it provides much aggressive grinding and much longer lifetime and consistent quality. We have patented this new technology. Applications: Fit on HTC machine and other walk-behind floor machines with quick-release holders/plates for Fast removal of various coatings, levelling and grinding soft and very abrasive concrete. Advantage: Very tough and hard bond together with special TCD provide fast and very durable grinding for soft but very abrasive concrete. Remarks: TCD is a special kind of PCD with much more stronger(tough, abrasive) 1#: Line-Up TCD Scraper, suitable for green concrete, soft and very abrasive concrete, at very long lifetime. Germany customer tested the lifetime is about 800M2(and the normal diamond Scraper is about 50 M2), not suitable for hard concrete. 6#, 16/20#, 30#, 50#: Normal TCD Scraper, non-line-up, suiatble for old/hard or soft/abrasive concrete with reasonable speed and longer life than normal diamond Scraper.
