The JX350 Face & Top Grinding Machine is an industrial-grade CNC carbide circular saw blade grinding system developed by Dongguan Lingbang Machinery Technology Co., Ltd. Engineered for high-volume production, the JX350 independently performs face grinding, top grinding, flat grinding, ladder-tooth grinding, and profile grinding in a single setup. Equipped with an integrated full-servo robot arm loading system (X-axis & Y-axis electromagnetic servo, zero pneumatic components), the JX350 enables unattended 24-hour continuous operation. It achieves a radial runout accuracy of ≤0.03 mm and a concentricity of ≤0.02 mm in fine grinding mode, making it the automated workhorse for saw blade diameters from 120 mm to 450 mm across aluminum, woodworking, PVC, and non-ferrous metal processing industries.
The JX350 features a fully servo-driven system — servo feed, servo + worm gear angle adjustment, and servo-controlled automatic gear shifting — enabling digital parameter storage and batch-to-batch repeatability. The QT500 ductile iron core moving components and custom imported high-precision spindle ensure exceptional rigidity under continuous production loads. Unlike conventional face-and-top grinders requiring manual loading, the integrated robot arm eliminates operator dependency, reducing cycle time by up to 40%. The swing head uses a worm gear positioning system with hydraulic stroke control for efficient angle changes, while open programmable architecture supports L-R-L-R flat, trapezoid-flat, 3L-1R, 3R-1L, and custom compound tooth profiles in a single clamping.

The JX350 is optimized for carbide-tipped (TCT) circular saw blades. The integrated robot arm enables unattended 24-hour continuous production. Flat-tooth, ladder-tooth, L-R-L-R flat, 3L-1R, and 3R-1L compound profiles are all supported in a single clamping.
X-axis and Y-axis electromagnetic servo robot arm with screw drive — zero pneumatic components — delivers higher precision, stability, and rigidity for unattended 24-hour continuous operation.
Fine grinding mode achieves a radial runout of ≤0.03 mm (30 microns) with a concentricity of ≤0.02 mm, meeting the tolerance requirements for high-end carbide saw blade production and resharpening.
Supports L-R-L-R flat, trapezoid-flat, 3L-1R, 3R-1L, and custom compound tooth geometries in a single clamping — no multi-machine coordination required.
Manual angle input with servo automatic swing head positioning via worm gear mechanism. Upper-lower stroke uses hydraulic control with servo tool setting for efficient and precise angle changes.
High-precision, high-rigidity, high-speed custom imported spindle assembly ensures consistent grinding quality across high-volume production and resharpening workflows.
Open programmable architecture with CNC automation. Digital parameter storage enables one-touch recall when switching between blade specifications — no manual recalibration needed for batch changeovers.

What is the JX350 Face & Top Grinding Machine?
The JX350 is an industrial-grade CNC carbide circular saw blade grinding machine manufactured by Dongguan Lingbang Machinery Technology Co., Ltd. It performs face grinding and top grinding on a single standalone unit with an integrated full-servo robot arm loading system (X+Y axis electromagnetic servo, zero pneumatics), enabling unattended 24-hour continuous operation. It achieves a radial runout of ≤0.03 mm and a concentricity of ≤0.02 mm, supporting blade diameters from 120 mm to 450 mm.
How is the JX350 different from the DM100 and QH200 models?
The JX350 is the automated robotic version of Lingbang’s face-and-top grinding lineup, featuring a full-servo electromagnetic robot arm for automatic blade loading — enabling lights-out 24-hour production. The DM100 (120–650 mm, ≤0.02 mm) is a mid-to-high-range manual grinder with lighter footprint, while the QH200 (100–800 mm, ≤0.03 mm) is a heavy-duty large-capacity manual grinder. The JX350 targets high-volume production lines requiring automation and consistency at scale.
What types of saw blades can the JX350 grind?
The JX350 handles carbide-tipped (TCT) circular saw blades from 120 mm to 450 mm in diameter. It supports L-R-L-R flat, trapezoid-flat, 3L-1R, 3R-1L, and custom compound tooth geometries in a single clamping. It is designed for aluminum, woodworking, PVC, and non-ferrous metal saw blades.
How accurate is the JX350 grinding machine?
In fine grinding mode, the JX350 achieves a radial runout of ≤0.03 mm (30 microns) and a concentricity of ≤0.02 mm. This precision is achieved through its servo worm gear swing head positioning system, full servo electric control, QT500 ductile iron core construction, custom imported spindle, and full-servo robot arm that eliminates manual handling errors.
What is the warranty on the JX350?
The JX350 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 core components carry lifetime structural integrity assurance. Lingbang provides lifetime technical support and genuine spare parts supply. Contact alex@lingbangjixie.com for extended warranty options.
Is the JX350 suitable for resharpening used saw blades?
Yes. The JX350 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 for new blade vs. resharpening workflows. The robot arm ensures consistent loading precision, making it ideal for high-volume resharpening service centers.
