Precision Surface Grinder Service and Rebuilds

Surface grinders are the foundation of precision finishing in every machine shop. When your grinder develops spindle noise, vibration, or inconsistent flatness, it can compromise part quality and production efficiency. C & C Machine Tool Inc. provides professional surface grinder repair and maintenance services throughout Minneapolis and the surrounding Minnesota region.

We work with manual and hydraulic surface grinders from all major brands, offering complete rebuilds, alignment, and spindle services that restore original precision. Our goal is simple: to ensure your machines hold tolerance, produce consistent finishes, and operate safely.

Since 2015, our family-owned business has helped Minnesota’s machinists, fabricators, and manufacturers keep their grinding equipment running like new—with craftsmanship, transparency, and reliability at every step.

Why Surface Grinder Repair Is Essential

Surface grinders demand accuracy down to the thousandth of an inch. Over time, mechanical wear, vibration, and lubrication issues can cause performance drift, affecting both quality and efficiency.

Professional grinder service ensures:

  • Accurate flatness and parallelism

  • Smooth spindle operation and reduced noise

  • Consistent magnetic chuck holding force

  • Proper hydraulic and feed system function

  • Safe, predictable machine operation

Neglecting routine maintenance can lead to poor surface finish, uneven wear, and unexpected breakdowns—each of which costs valuable production time.

Common Surface Grinder Issues We Repair

Our technicians are highly experienced in diagnosing and repairing all major mechanical, electrical, and hydraulic surface grinder problems, including:

  • Spindle bearing wear or noise

  • Damaged or uneven magnetic chucks

  • Table feed malfunctions

  • Hydraulic system leaks or pump failures

  • Wheelhead vibration or imbalance

  • Worn ways or gib adjustments

  • Electrical and motor faults

  • Poor surface finish or burn marks

  • Table or saddle misalignment

  • Insufficient coolant flow or lubrication

Each repair is performed using precision measurement equipment to verify flatness, alignment, and smooth table travel.

Our Surface Grinder Repair Process

Inspection and Testing

We evaluate spindle runout, table travel, hydraulic function, and chuck performance. Using precision indicators, we measure flatness and parallelism.

Diagnosis and Reporting

 A detailed service report outlines issues, corrective actions, and estimated costs.

Mechanical Repair and Rebuild

Spindles are rebuilt or replaced, bearings installed, ways adjusted, and hydraulic systems resealed. Electrical and coolant systems are tested and repaired.

Alignment and Calibration

We align table movement, level the saddle, and true the chuck for accurate, repeatable grinding.

Testing and Verification

 After service, we perform controlled grind tests to verify accuracy and surface finish before releasing the machine.

This comprehensive process ensures that every grinder we service meets or exceeds its original performance standards.
