Brief Description About CNC Surface Grinding Machine

  • Operating CNC Surface Grinding Machine is very much depended on the operator’s skill of programming, knowledge & experience. But with PINNACLE-make High Precision CNC 3X surface grinding machines, the operating of machines is made simple & precise wherein the operator only needs basic knowledge of surface grinding operation. PINNACLE has developed customized screens which don’t need lengthy programming & programming code skills but only needs to feed in step by step NC data of surface grinding process.

  • The regular developed canned cycles include Step Grinding, Continuous grinding, Plunge grinding & Face grinding. PINNACLE has also developed various Customized canned cycles against customer’s specific requirement.

  • CNC Surface Grinding Machine Manufacturers provide advanced equipment designed for high precision and efficiency in various industrial applications.

  • CNC 3X series machines are designed and developed to cater almost all Rotary Surface Grinding Machine applications such as Profile Grinding, Creep feed grinding & Spline grinding using necessary special attachments / equipments / Jigs / Fixtures.

  • Longitudinal Movement i.e. X-Axis, Vertical Movement i.e. Y-Axis and Cross Movement i.e. Z-Axis is driven by A. C. Servo Motor directly coupled to Ball Screws with Zero backlash Servo Couplings over Precise Ground Prism-Flat guide ways.

  • All the Turcite B-Lined Prism Flat Guide ways / L. M. Guide ways are equipped with Auto Lubrication unit has facility of Re-Circulating Filtration system with Low & High signal and Pressure drop signal for Constant Dust-free Hydro-dynamic flow. It gives high sensitive mechanism to achieve micronic movements with stick-slip free motion.

  • Grinding Spindle-Cartridge is assembled with Imported SUPER PRECISION BEARINGS grease packed with Imported Grease filled for Life for long trouble free service. If you are in need of a CNC Surface Grinder, the CNC 3X series offers unparalleled precision and ease of use.

  • CNC 3X series High Precision Surface grinding machines are available from Table size 750 x 300 mm to 3000 x 700 mm.

Frequently Asked Questions

The CNC 3X Series is a high-precision surface grinding machine with computer numerical control, designed to perform complex grinding tasks such as profile, creep feed, and spline grinding with minimal operator input. It simplifies operations by requiring only basic knowledge of surface grinding, while offering unmatched accuracy and efficiency.

The machine operates on three axes: longitudinal (X-Axis), vertical (Y-Axis), and cross (Z-Axis). Each axis is driven by AC servo motors coupled with precision ball screws and zero-backlash couplings, ensuring micronic, smooth, and stick-slip-free movements.

Pinnacle provides customized user-friendly screens that eliminate the need for lengthy coding. Operators simply feed step-by-step NC data to execute operations like step grinding, continuous grinding, plunge grinding, and face grinding, making the machine highly intuitive.

These machines are ideal for high-precision industrial applications including tool-room work, automotive components, gear manufacturing, and heavy machinery parts. They can handle complex surface grinding tasks, such as profile and spline grinding, using specialized attachments or fixtures.

Table sizes range from 750 x 300 mm to 3000 x 700 mm, accommodating a wide variety of job sizes and industrial requirements.
