Product Description

Surface Grinding Machine: Precision Engineered for Uncompromising Rigidity and Long-Term Accuracy

Crossfeed Surface Grinder with Dust Collector | Low Vibration Design
Crafted for industrial-grade metal finishing, the Surface Grinding Machine stands as a cornerstone of precision manufacturing. Engineered with high-strength wear-resistant cast iron throughout its body and worktable, it delivers exceptional structural integrity, vibration damping, and long-term geometric stability. This robust foundation ensures micron-level accuracy across decades of heavy-duty service, minimizing maintenance costs and maximizing ROI.

I. Core Structural Design: The Foundation of Precision
A) High-Strength Cast Iron Construction

B) Body & Table Material: Grade G300+ cast iron, heat-treated for optimized stress relief and enhanced wear resistance. Brinell hardness (HB220+) ensures superior resistance to deformation under load.

C) Rib-Reinforced Frame: Finite Element Analysis (FEA)-optimized internal ribbing increases torsional rigidity by 35% vs. conventional designs, eliminating chatter during aggressive grinding.

D) Precision-Ground Guideways

E) Scraped & Turcite-Bonded Surfaces: Table guideways feature hand-scraped contact surfaces with low-friction Turcite® liners, ensuring smooth hydraulic motion and ≤0.003mm/m straightness tolerance.

II. Advanced Motion Systems: Hydraulic & Mechanical Synergy

A. Longitudinal Table Movement (X-Axis)
Hydraulic Drive System: Powered by a Siemens Rexroth hydraulic unit with pressure-compensated variable displacement pump.
German Damping Technology: Integrated Bosch Rexroth hydraulic cushioning cylinders eliminate end-of-stroke impact, achieving ±0.005mm positioning repeatability.
Speed Range: Infinitely variable 3-25 m/min for roughing to finishing.
B. Cross Traverse (Y-Axis)
Dual-Mode Operation:
Hydraulic Feed: For automated reciprocating grinding (stroke adjustable via CNC).
Manual Precision Handwheels: Ground stainless steel dials with 0.001mm graduations for fine adjustments.
THK Linear Guides: Japanese C0-grade roller-type guides ensure ±0.002mm repeatability under lateral loads.
C. Vertical Infeed (Z-Axis)
Motorized & Manual Control:
Rack-and-Pinion Rapid Adjustment: 300mm/min motorized ascent/descent.
Fine Manual Feed: 0.001mm/division vernier wheel.
Precision Ballscrew Drive: TBI Motion (Taiwan) ground C3-class ballscrews with pre-loaded nuts eliminate backlash, guaranteeing ±0.003mm depth consistency.
III. Grinding Head Assembly: Power & Stability
High-Rigidity Spindle System
Precision Angular Contact Bearings: NSK P4-grade bearings rated for 15,000 RPM with forced-oil lubrication.
Dynamic Balancing: G0.4 balance grade at operating speeds reduces vibration-induced surface ripple.
Coolant Management
High-Pressure Flood Coolant: 50L/min pump with magnetic separator and paper filter unit (≤10μm filtration).

Conclusion: The Industrial-Grade Workhorse
This surface grinding machine epitomizes precision durability through its high-tensile cast iron construction, brand-certified motion systems (THK, TBI), and intelligent hydraulics (Siemens/Bosch Rexroth). Engineered to deliver sub-micron flatness while slashing lifetime ownership costs by 40%, it excels in tool & die, aerospace bearing races, and precision mold base finishing. With ISO 2433-certified geometric accuracy and >95% mean time between failures (MTBF), it transforms grinding from a cost center to a competitive advantage—proving that true precision is measured not just in microns, but in decades.

About DURAMA's Surface Grinding Machine

1. Working principle: The surface grinder is mainly composed of components such as the bed, worktable, spindle, grinding head, guide rail, feed system, and lubrication system. The bed is the supporting structure of the entire machine tool, the worktable is used to place workpieces, and the spindle and grinding head are key components for achieving grinding operations. Surface grinders mainly use the rotation of grinding wheels to grind workpieces. During the grinding process, the grinding wheel rotates at high speed and continuously grinds the surface of the workpiece through contact with it, thereby achieving the required accuracy and surface quality.
2. Scope of application: Surface grinders are widely used in the field of metal processing, suitable for grinding various metal materials such as aluminum alloys, steel, stainless steel, copper alloys, etc. Surface grinders are widely used in fields such as mold manufacturing and processing, mechanical manufacturing and parts processing, aerospace, automotive parts, optical lenses, clocks, and electronic components.
3. Equipment advantages: The positioning accuracy and repeatability accuracy of the Durama surface grinder are both high, which can ensure high-precision machining of parts and is suitable for occasions that require high-precision machining. The Durama surface grinder can process multiple workpiece surfaces in one clamping, usually only detecting the first piece, eliminating many processes in ordinary machine tool processing and improving production efficiency. The machining process of the Durama surface grinder can be automatically completed according to the input program, and the operator only needs to perform initial tool alignment, workpiece loading and unloading, tool replacement and other operations, greatly reducing the physical labor intensity of the operator.Surface Grinding machine, surface grinder, grinder machine, grinding machine, milling machine....
