Precision Grinding for Industrial Demands

The CPG-700 is designed to address the rigorous demands of crankshaft and crankpin grinding in automotive and industrial engine maintenance. With a capacity to accommodate crankpins up to 150 mm in diameter and 700 mm in length, it offers precise, efficient operation for both repair and manufacturing applications. Its variable working speed and robust electric drive help maintain superior grinding consistency.


Advanced Cooling and Lubrication

Ensuring both safety and machine longevity, the integrated coolant system efficiently dissipates heat during operation, minimizing thermal expansion and ensuring smoother finishes. Coupled with an automatic lubrication system, the CPG-700 reduces wear and tear, keeping maintenance to a minimum and extending the service life of critical components.


Ease of Use and Durability

Built with reliability in mind, this surface grinding machine features manual controls, a sturdy V & Flat type table slide way, and a compact, efficient layout. The high-capacity fuel tank and durable construction make it suitable for continuous operation in demanding industrial settings, while the simple color-coded manual system supports operator accuracy and ease of use.
