1. JS-833V / 840V employ an AC inverter-duty motor combined with an inverter in functioning a stepless variable-spindle-speed change. It is easy to reach the required main spindle speed by lightly turning the speed controller without adjusting the belt. Thus, it is able to increase efficiency and reduce cost. And, it can also perform high torsion at a low spindle speed.
2. JS-833 is designed as an 18-different spindle speed machine. To change the main spindle speed, it requires adjusting the belt. As following the instruction to set up the belt position, it can reach a required main spindle speed.
3. The dual-function working tables of JS-833 / 833V / 840V are standard accessories. They can be converted into vise-typed stages after 180 o rotation, and turned by any angles to the processing positions of work pieces.
4. JS-833V / 840V both have an attached main spindle speed meter on them which can show the speed of main spindle exactly.
5. JS-833 / 833V / 840V are precise constructions and patterned designs. As an accident occurs in process of the tapping stroke, just use one hand to lightly push the grip handle backward so that the machine can return back the knife immediately to avoid the tapping tip being broken. They are safe and reliable.
6. The bases and coolant systems of JS-833 / 833V / 840V are made as one piece stand, which are standard accessories. They are practical, beautiful and convenient
7. All exported machines are assembled with vertical type and packed into heavy-duty cardboard boxes individually according to the environmental protection of packaging practice.
