MPA670 Grinding Macheine

Dedicated Grinding Machine for Electrolytic Copper Foil Industrial Rollers

This project was developed in response to the needs of a global leading manufacturer of electro-deposited copper foil. In the copper foil production process, surface consistency of industrial rollers is a critical quality factor. Therefore, a highly stable mechanism capable of continuous reciprocating grinding is required.

The design concept is based on the MPA670.15.3 platform, with targeted structural optimization for this specific application.

Structural Optimization

‧ Structure： The conventional lathe compound rest, feed gearbox, and feed rod have been removed. The transmission chain is simplified to eliminate unnecessary mechanical variables and improve operational stability.

‧ Drive Configuration： 2HP geared motor drives a 50 mm lead screw, paired with fixed bronze double nuts to ensure smooth, precise linear motion.

‧ Balancing Design： A counterweight is installed at the rear of the saddle on the 16" bed platform. This ensures proper center-of-gravity balance and dynamic stability during long-stroke travel.

Operating Parameters

Spindle Speed： Fixed at 160 rpm

Z-axis Feed Rate： Stable control from 0.76 mm/s to 3.06 mm/s

Customization Advantages & Benefits

‧ Auto-Reversal Stroke Function： An integrated automatic stroke reversal system enables consistent reciprocating movement of the saddle within a preset travel range.

‧ Purpose-Built Design： This machine is not intended for general shaft turning. It is purpose-built for the copper foil industry and other precision roller manufacturing processes.

‧ High Consistency： The design supports long-stroke repetitive machining with optimized mechanical balance and mechanical auto-reversal, ensuring high consistency and repeatability of finished roller quality.
