The JS350 Double Side Grinding Machine is an industrial-grade full-servo double side grinding system developed by Dongguan Lingbang Machinery Technology Co., Ltd., purpose-built for carbide-tipped (TCT) circular saw blades. Equipped with a fully servo-driven automatic robot arm loading system (X-axis & Y-axis electromagnetic servo, zero pneumatic components), the JS350 enables unattended 24-hour continuous operation for high-volume production lines. It achieves a thickness tolerance of ≤0.01 mm and an end face runout of ≤0.02 mm in fine grinding mode, making it the ultimate automation solution for saw blade diameters from 120 mm to 450 mm across aluminum, woodworking, PVC, and non-ferrous metal processing industries.
The JS350 features a full servo electric system covering tool setting, angle adjustment, tooth indexing, and feed control 鈥?all driven by CNC automation with digital parameter storage for batch-to-batch repeatability. The QT500 ductile iron frame and custom imported high-precision spindle ensure exceptional rigidity and vibration damping, while the open programmable architecture with multiple reciprocating grinding sequences adapts flexibly to diverse saw blade geometries. Unlike conventional double side grinders requiring manual loading, the robot arm eliminates operator dependency, reducing cycle time by up to 50% and enabling lights-out manufacturing.

What is the JS350 Double Side Grinding Machine?
The JS350 is an industrial-grade full-servo double side grinding machine manufactured by Dongguan Lingbang Machinery Technology Co., Ltd., designed for carbide-tipped (TCT) circular saw blades. It features an integrated full-servo robot arm loading system (X+Y axis electromagnetic servo, zero pneumatics), enabling unattended 24-hour continuous operation. It grinds both side faces of saw blade teeth simultaneously in a single pass with a thickness tolerance of ≤0.01 mm and an end face runout (radial runout) of ≤0.02 mm in fine grinding mode, suitable for blade diameters from 120 mm to 450 mm.
How is the JS350 different from the MCC650E double side grinder?
The JS350 is the automated robotic version of Lingbang’s double side grinding lineup, featuring a full-servo electromagnetic robot arm for automatic blade loading and unloading — enabling lights-out 24-hour continuous production. The MCC650E is a manual-loading double side grinder with a larger capacity range (120–800 mm vs. 120–450 mm). The JS350 targets high-volume production lines requiring automation, while the MCC650E is suited for workshops handling diverse blade sizes. Both achieve ≤0.01 mm thickness tolerance and ≤0.02 mm end face runout.
What types of saw blades can the JS350 grind?
The JS350 handles carbide-tipped (TCT) circular saw blades from 120 mm to 450 mm in diameter with bore diameters from 12 mm to 60 mm, tooth thickness from 1 mm to 12 mm, and tooth pitch from 7 mm to 100 mm. It is designed for aluminum, woodworking, PVC, and non-ferrous metal saw blades in high-volume production environments.
How accurate is the JS350 grinding machine?
In fine grinding mode, the JS350 delivers a thickness tolerance of ≤0.01 mm and an end face runout (radial runout) of ≤0.02 mm. This precision is achieved through its full servo electric system, QT500 ductile iron machine frame, custom imported high-precision spindle, and full-servo robot arm loading system that eliminates manual handling errors.
What is the warranty on the JS350?
The JS350 comes with a 1-year full machine warranty covering all servo components, the robot arm system, and the custom imported spindle. The QT500 ductile iron frame carries lifetime structural integrity assurance under normal operating conditions. Lingbang provides lifetime technical support and genuine spare parts supply throughout the machine lifecycle. Contact alex@lingbangjixie.com for extended warranty options.
Is the JS350 suitable for resharpening used saw blades?
Yes. The JS350 is designed for both new blade production and resharpening services. Its full servo programmable system with digital parameter storage allows operators to configure and recall different grinding programs. The robot arm ensures consistent loading precision across new blade and resharpening workflows, making it ideal for high-volume resharpening service centers.
