Products
Cutting machine
Crystal Cutter, Neo Expensive  MC-623Ex
[Outline]
This machine is developed for single-cutting or multi-cutting super hard materials
such as advanced ceramics (HP-Si3N4, HP-ZrO2, HP-SiC), cemented carbide, etc., accurately and efficiently. The feed rate of work table ranges widely. The depth of cut and the feed rate may be varied to achieve optimum results with your sample. With our accumulated experience, it is designed with high rigidity to minimize chipping and crack.
Lapping machine
Doctor-lap Ace ML-482A
[Outline]
This is a table type lapping machine with a 250mm diameter lapping plate (optionally 300mm), and 125mm diameter Power head to process samples very efficiently. Variable speed and pressure of Power Head will allow operator to select and meet the most demanding laboratory requirements.
