The motor case and headstock of all-metal machine tools is jointed completely. Main parts configure with metal structure and no plastic components in the whole machine body, such as motor box, headstock, hand wheels, slider, 3-jaw chunk/4-jaw chunk, turning tools clamping jaw, machine bed, gear, side cover, working table, connection piece, tailstock, countershaft, drive belt cover etc. 2. Fan built-in motor is featured with Ultra-quiet & high rotary speed. That's special customized option for motor cooling & effective work. 3. The most parts of machine tools are dealt with two surface treatment methods of electroplating and ink-jet anodized to make appearance more cleaning & glorious, lasting rust-proof.4. Machine bed is made of Europe standard T-type aluminum material, moving more precisely &smoothly. 5. 3C quality assured transformers have the function of over-current, over-voltage and over-heat protection. 6. To improve the stability and service life, the connection block be fixed by square nuts, which avoid screw loosing after long time vibration. 7. The connection block adopts dovetail structure, which matches with each slot of the machine tools parts to enhance its performance and accuracy. 8. Children-proof design & safe fillet processing technology, they are all to prevent metal parts from scratching the skin. 9. Versatile application: The turning tools of mini metal lathe are made of steel material, which can be perfectly used to process the soft metal (gold, silver, copper & aluminum), acrylic and engineering plastics etc. 10. By adding some loose-preventing nuts on the side of small& big slider, not only avoid the gap after excessive vibration, but also improve the processing accuracy. 11. The whole hand wheel is made of super alloy material, which be assembled in X, Z axis and tailstock. Featuring with 0.02mm scale line, the hand wheel increases the precision when processing. (The scale lines are molded at one time, aren't sticky labe 12. The chuck is fixed by a hexagon nut to increase the tightness of the clamping tools (such as drill bits, cutters, wood-turning lathe driver). 13. 3/4 semi-circular structure designed hand wheel, that's quite convenient for dismantling connection pieces. 14. There are three parallel dovetail slots available on the big slider, which facilitate the movement of mini lathe tools and installment of the holders and the cutlery.15. Adding intermediate pieces under motor box, tailstock and lathe tools clamping jaw, which enlarge the machining rotary diameter & practical usage. 16. 3-jaw chuck can be used to clamp the material at a maximum diameter of 50mm, four-jaw single-action chucks is available. It is perfect optional choice for irregular shape (such as square, elliptical, hexagonal material), also expand the effective work area. Q and A: Q1: What's the usage of ZHRUI miniature machine tools? The miniature machine tools have the same features as big industrial machines, the only differences are their size and the 12V drive. You can use it for DIY model making and some little crafts, which is also able to process hard wood, soft metal, alloy etc...Based on its modularity and the child friendly use, that's ideal& creative product to inspire children hand-on skill&innovative ability.
