UB-MCQH260J·Tooth Grinding

Side, Front and Rear Angle Combination CNC Grinding Machine (3-Axis Robot Arm)

The UB-MCQH260J is a side, front and rear angle combination CNC grinding machine for carbide-tipped circular saw blades, built from one side-angle module and two front-and-rear-angle modules. Grinding all three angles in one setup takes out the re-fixturing steps between them, and the front and rear angles switch at a keypress; common tooth forms can also be run in a quick-grind mode that saves the wheel spindle swinging left and right. A three-axis robot arm loads from a multi-blade platform that detects and corrects mis-stacked blades, under full bus servo PLC control with remote monitoring and data collection. 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 315 mm diameter with arbor sizes 10 to 32 mm and tooth pitches up to 80 mm.

Highlights

Grinds side, front and rear angles in one combined pass, and switches to a side-angle plus rear-angle trapezoidal-flat routine without re-fixturing
Twin-head vertical side grinding forms both side angles of a tooth in one pass, covering alternate top bevel (ATB), wide-narrow, back-taper and uneven-pitch teeth
The radial side angle is ground by interpolation, so angle changes are made at the panel, not mechanically
Free tooth-form editing with saved profiles, plus one-keypress recall of flat-top, ATB and its flat-tooth variants, trapezoidal-flat (TCG) and uneven-pitch forms
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
