UB-MLQH400J·Tooth Grinding

3-Axis Saw Blade Front and Back Angle Grinding Machine

The UB-MLQH400J is a 3-axis 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. It grinds front angles from -5 to 25 degrees and back angles from 0 to 25 degrees, with bevel angles to ±45 degrees on both, at grinding widths of 1.5 to 12 mm and tooth pitches up to 80 mm. Diamond wheels run 180# to 600# 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, 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
