According to the carbide saw blade industry standard (JB/T 5735-2018 Woodworking Carbide Circular Saw Blade), blade axial runout and tooth-thickness consistency are the core indicators of cutting accuracy and surface quality. With a finish thickness tolerance of ≤0.01mm and axial runout of ≤0.02mm, JS350 meets the stringent requirements of international standards such as DIN 8083 / ISO 2935 for high-end saw blade manufacturing.

GMP2500 serves saw blade manufacturing and resharpening enterprises across multiple provinces in China and overseas markets such as Southeast Asia and the Middle East:
A: JS350 is a fully servo-driven CNC double-side saw blade grinding machine ,Featuring a full-servo and lead-screw driven built-in robotic arm, the JS350 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.
A: JS350 is Double-sided grinding of hard alloy circular saw blades with diameters ranging from 120 to 450mm and hole diameters from 20 to 80mm, suitable for automated robotic operations
A: In finish grinding mode, tooth thickness tolerance ≤0.01 mm and axial runout ≤0.02 mm.
A: The JS350 is a robotic double-side grinder, which simultaneously grinds both tooth flanks in a single clamping to control tooth thickness and tooth flank geometry. DM100 and QH200 are standalone tooth tip & flank grinders for cutting face and tooth tip (outer diameter) machining.
The optimal configuration is one JS350 matched with two JX350 units for maximum production efficiency.
Process recommendation: Complete double-side grinding on JS350 first, then carry out tooth tip & flank finishing on JX350. The three machines separately control tooth thickness, tooth angle and tooth surface grinding, forming a complete saw blade grinding production line.
A: 1-year full machine warranty (covering full-servo components and imported spindle). The QT500 ductile iron machine frame enjoys lifetime structural warranty. We provide free operation training and grinding technical guidance, lifelong technical support (remote or on-site response within 48 hours), and long-term supply of original spare parts. Contact alex@lingbangjixie.com for extended warranty options.
A: No. The JS350 is designed for mass production of new saw blades and supports 24-hour non-stop operation. For reconditioning used saw blades (finishing after tooth brazing), inconsistent dimensions of refurbished blades cannot meet unified processing standards.
A: Prepare the following conditions in advance:
① 3-phase 380V industrial power supply (total power: 5.8 kW);
② Installation space ≥2500 × 2800 mm (reserve space for operation and maintenance);
③ Floor bearing capacity ≥2000 kg/m² (machine net weight: 3250 kg);
④ Stable compressed air of 0.6–0.8 MPa;
⑤ Grinding wheel consumables (specifications: 80/100/125 mm).
Lingbang Machinery provides installation guidance and workshop layout planning suggestions.
A: The JS350 is equipped with two symmetrically arranged high-precision spindles fitted with profiled diamond grinding wheels. It synchronously grinds left and right tooth flanks in a single clamping.
