Product Overview
The industrial surface grinding machine executes precision abrasive machining using a rotating wheel to finish flat and parallel metallic surfaces. Built on a heavily ribbed, stress-relieved Meehanite cast iron bed, the machine absorbs high-frequency cutting forces to eliminate chatter. The saddle and table ride on preloaded linear roller guideways or hand-scraped box ways to ensure smooth reversal during reciprocating motion. Integrated closed-loop feedback and multi-stage coolant filtration prevent thermal distortion and surface burn during high-removal-rate operations.

Key Features
Cartridge-Type Spindle: Supported by high-precision angular contact ball bearings, restricting radial runout to under 0.002 mm under load.
Finite Element Analysis (FEA) Base: Ribbed Meehanite casting structure engineered to maximize dynamic rigidity and dampen vibration.
Proportional Hydraulic Drive: Delivers infinitely variable longitudinal table speeds from 3 m/min to 25 m/min with minimal reversal shock.
Automatic Downfeed System: Programmable micro-feed increments down to 0.001 mm per pulse, featuring automatic spark-out cycles and rapid elevation.
Dual-Stage Filtration: Combines a magnetic separator and paper bed filter to continuously remove ferrous swarf and prevent workpiece scratching.

Mold & Die Fabrication: Grinding injection mold cavity plates, punch holders, and stripper plates to strict mating tolerances.
Aerospace Component Production: Finishing high-temperature alloy turbine shim plates, structural brackets, and wear components.
Automotive Tooling: Manufacturing stamping dies, trimming blades, and cylindrical punch guides.
General Precision Engineering: Batch processing parallel shims, spacer blocks, and machine tool replacement parts.
Match Workpiece Envelope: Select table travel dimensions that allow at least 50 mm of clearance on all sides for safe wheel approach and clamping.
Size Spindle Power: Use 5.5 kW motors for standard finishing passes; specify 7.5 kW or higher for heavy stock removal on hardened tool steels.
Determine Axis Drive Type: Choose hydraulic reciprocating tables for dedicated flat plate production; select CNC ball-screw drives for complex slot grinding, profiling, or unattended multi-step runs.
Confirm Workholding Needs: Specify electromagnetic chucks for ferrous plates; choose mechanical vacuum chucks or sub-plates for non-ferrous metals or thin-walled parts.
Cast Iron Thermal Aging:
Raw Meehanite castings undergo 48-hour stress-relief annealing and aging cycles before machining to prevent long-term structural warping.
Precision Guideway Scraping:
Box ways are hand-scraped to an 18 to 22 bearing point density per square inch for optimal oil film retention.
Laser Interferometer Calibration
Axis positioning accuracy and backlash are verified using Renishaw laser interferometers across full travel ranges.
Dynamic Ballbar Testing
Diagonal circular tests confirm squareness and contouring accuracy between longitudinal and cross axes.
Spindle Runout Verification
Dynamic runout is measured at the spindle nose using high-precision capacitive sensors during a 4-hour thermal stabilization run test.
Optional Configuration
Overhead Wheel Dressing Unit
Programmable diamond roll dresser mounted on the wheel guard for automated contour dressing.
Creep Feed Grinding Package
High-torque spindle drive and high-pressure coolant nozzles for single-pass deep slot machining.
Enclosed Safety Guarding
Full sheet-metal enclosure with interlocked safety doors and mist extraction ports (CE/OSHA compliant).
In-Process Gauging
Renishaw or Marposs touch probes measuring workpiece thickness automatically during cycles to trigger finish-size stops.
