What is the difference between mechanical arm and manual grinding machines?

JX350 mechanical arm series features dual-position synchronous grinding (top and face in one setup), auto loading/unloading, and 24h continuous operation. Manual machines rely on operator experience with lower efficiency and consistency.

Is saw blade resharpening cost-effective compared to buying new ones?

Yes. Resharpening costs only 20-40% of new blades and can be done 3-5 times. JX350 restores cutting angles precisely, delivering sharpness comparable to new blades. Total savings exceed 60%.

How to choose a saw blade grinding machine manufacturer?

Lingbang has 11 years of expertise in carbide saw blade grinding machines. Our Dongguan factory supports on-site inspection and sample grinding. JX350 offers 24h continuous operation for high-volume production.

Product Overview

JX350 CNC Tooth Top & Face Grinding Machine (Robotic Industrial Model)

The JX350 is an industrial-grade tooth top and face grinding machine equipped with a robotic arm and hydraulic servo system, professionally designed for high-precision tooth tip and flank grinding of TCT circular saw blades.

All tooth tip and tooth flank grinding procedures can be completed in a single workpiece clamping. Operators only need to replace matched grinding wheels to switch different grinding processes. The machine precisely guarantees tooth sharpness and saw blade concentricity, serving as core processing equipment for saw blade manufacturers and professional resharpening centers.

Featuring a full-servo and lead-screw driven built-in robotic arm, the JX350 supports automatic loading and unloading and 24-hour continuous operation. The robotic working range covers 120–450 mm, and the machine can process saw blades up to 650 mm in diameter.

Close-up: Automatic Saw Blade Loading & Unloading

Convenience and stability of the robotic arm

The feature of the robotic arm grinding machine is that one person can operate more than 30 devices, fully meeting the production efficiency requirements of large manufacturing companies, and widely used in various saw blade manufacturing enterprises. In the past, traditional robotic arms controlled by cylinders were prone to instability during the automatic loading and unloading process, which severely affected overall production efficiency due to unstable air pressure. JX350 robotic arm adopts X, Y, Z three-axis servo positioning robotic arm and electromagnetic-controlled saw blade loading and unloading, which ensures overall stability and feeding accuracy. It can fully meet high-quality grinding requirements and solve many issues caused by manual operations. X and Y axes adopt the motion mode of servo motor + ball screw, providing movement and positioning in the X and Y directions. The Z axis serves as the center axis and adopts imported planetary angle motor + servo motor to precisely control the rotation angle and feeding accuracy. It can fully meet customer demands for bore tolerance fits of H7/H8 levels. For the problem of stacked saw blades that cannot be separated, the combination of an electromagnet and the robotic arm can automatically separate overlapping blades. Once the weight of the saw blades exceeds the set limit, the robotic arm will stop working promptly and send a signal, reducing product waste caused by oil and sawdust residue.

As specified in the industrial standard JB/T 5735-2018 Woodworking Tungsten Carbide Tipped Circular Saw Blades, saw blade radial runout is the core indicator for evaluating cutting precision and workpiece surface finish.

Saw blades processed by the JX350 achieve radial runout tolerance within ≤0.03 mm, fully complying with stringent international high-end manufacturing standards including DIN 8083 and ISO 2935.
