Weizhihao CNC Serrated and Insert Grinders

Weizhihao CNC grinders MF100CNC and MF250CNC process toothed serrated blades and indexable tungsten carbide inserts for woodworking cutters. Four-axis CNC interpolation on MF100CNC maintains exact serration pitch. Spares include insert clamping cassettes, touch probes, ball screws, and servo drives.

Weizhihao Grinder Maintenance and Overhaul

Scheduled maintenance and mechanical overhaul programs support Weizhihao MF series sharpening machines across industrial toolrooms. Technicians eliminate spindle runout, align linear guideways, and calibrate CNC axes. Replacements include angular contact bearings, drive belts, seals, and sensors.

Dial-indicator inspection of grinding spindle radial and axial runout tolerances
Geometric leveling of linear guideways and resurfacing of electromagnetic chucks
Calibration of servo feed pitch, indexing pawls, and proximity limit switches
Supply of matched spindle bearings, timing belts, shaft seals, and coolant pumps

Automated Grinding Technology for TCT Circular Saw Blades

Weizhihao automatic and CNC circular saw blade sharpening machines across the MF125, MF127C, MF128, MF158C, and MF158CNC series are engineered for high-throughput maintenance of tungsten carbide-tipped blades in furniture factories and sawmills.

Servo-controlled feed axes maintain exact hook and clearance angles while executing complex tooth geometries including alternate top bevel and triple-chip grind profiles.

Fully enclosed wet grinding cabinets supply continuous flood coolant to the diamond wheel contact zone, preventing thermal micro-cracking and cobalt binder leaching.

Structural Design of Heavy-Duty Linear Knife Grinders

Weizhihao linear knife grinding machines in the MF256, MF2510CNC/2515CNC, and MF2518–MF2535 series deliver precision edge restoration for straight planer, veneer peeling, paper cutting, and wood chipper knives up to 3500 mm in length.

Stress-relieved welded steel beds prevent structural deflection under heavy carriage travel.

A rotary electromagnetic chuck table provides uniform holding force across long blade spans and tilts smoothly from 0 to 90 degrees, while automatic vertical downfeed increments control stock removal rates accurately.

Versatility of MF2718 Series Universal Tool Grinders

The Weizhihao MF2718B-I, MF2718B-II, MF2718C-III, and MF2718D universal tool and cutter grinders consolidate sharpening operations for shell mills, finger-joint cutters, spiral router bits, and planer cutterheads onto a single cast-iron platform.

The longitudinal worktable glides on precision ball-bearing linear ways for sensitive manual or motorized traverse feedback.

Multi-axis indexing workheads equipped with interchangeable dividing plates and precision arbors allow rapid setup transitions across diverse woodworking and metalworking cutting tools.

Template-Guided Profile Grinding on MF223 Machines

Weizhihao MF223B and MF223C profile knife grinders enable woodworking plants and custom millwork shops to grind and resharpen shaped moulding knives directly from 1:1 templates.

A hardened stylus follower traces the master template contour while guiding the rotating cutterhead arbor across the profiling wheel.

The tilting spindle head adjusts for primary and secondary clearance angles plus side relief, and an integrated diamond dressing attachment shapes the grinding wheel periphery to match the exact stylus tip radius.

Four-Axis CNC Serrated and Indexable Insert Grinding

The Weizhihao MF100CNC four-axis CNC serrated knife grinder automates the complex geometry required for toothed packaging blades, granulator knives, and serrated industrial cutters.

Coordinated four-axis servo interpolation guarantees uniform tooth pitch, gullet depth, and bevel angle along the entire blade edge.

Complementing this capability, the MF250CNC CNC insert blade grinder restores replaceable tungsten carbide inserts used in helical cutterheads and indexable woodworking routers with micron-level dimensional consistency.

Toolroom Configuration and Consumable Spare Support

Selecting an integrated Weizhihao Machinery sharpening setup involves matching circular blade diameters, straight knife lengths, and cutterhead bore specifications to daily factory tooling workloads.

Machines are supplied with customized arbors, collet chucks, electromagnetic chuck controllers, and magnetic coolant separators.

Ongoing factory operations are supported with matched replacement spindles, ball screws, servo drives, tracing pins, and resin-bond diamond or CBN grinding wheels tailored to HSS and tungsten carbide tooling grades.
