UB-MLQH400B·Tooth Grinding
Fully Automatic Front and Back Angle Grinding Machine
The UB-MLQH400B is a fully automatic front and back angle grinding machine for carbide-tipped circular saw blades. The front angle is the rake face that meets the workpiece first; the back angle is the clearance behind the cutting edge. Diamond wheels run 180# to 600# on both angles, at 4 to 20 teeth a minute. A three-axis gantry robot loads from a multi-blade platform that detects and corrects mis-stacked blades. The grinding units are modular cast iron on HIWIN roller guideways and NSK precision bearings, holding accuracy to 0.02 mm, and the guideway drive and electrical cabinet sit behind a sealed partition away from the coolant. It covers blades from 100 to 405 mm diameter with arbor sizes 10 to 32 mm and tooth pitches up to 80 mm, and one operator can run several machines.
Highlights
- Front and rear angle grinding in one machine, switched at a keypress
- Free tooth-form editing with saved profiles, plus one-keypress recall of flat-top, alternate top bevel (ATB) and its flat-tooth variants, trapezoidal-flat (TCG) and uneven-pitch forms
- Common tooth forms can be run in a quick-grind mode that saves the wheel spindle swinging left and right
- Wheel-wear compensation is set separately for left, right and flat teeth and the 45 degree chamfer, so uneven wear is not carried into the tooth
- Front-angle grinding offers a fast oscillating step-feed pass or a repeated reciprocating step-feed pass
- Full bus servo PLC control with remote monitoring, plus physical buttons and an electronic handwheel for tool setting
