Timing Belt (1.5×118B)
The timing belt is the transmission element between the stepper motor and lead screw on wire-cut EDM machines. Specification 1.5×118B (pitch 1.5mm, pitch line length 118 inches, B tooth profile). Made with a high-strength neoprene or polyurethane body reinforced with fiberglass or steel tension members, it provides an accurate transmission ratio with zero-slip characteristics, precisely transferring motor rotation to the lead screw for accurate table positioning. Compared with gear or chain drives, timing belts run quieter, require no lubrication and are easy to maintain. With precise tooth profile and excellent wear resistance, it suits the precision X/Y-axis drive systems of WEDM machines — a key transmission component ensuring contour machining accuracy.
