    Product Overview

    JS350 Double Side Grinding Machine – Industrial Full-Servo Type with Robot Arm is a fully servo-driven CNC double-side saw blade grinding machine designed for the simultaneous precision grinding of both tooth flanks of carbide circular saw blades. It performs synchronous grinding of both tooth sides in a single clamping, precisely controlling tooth thickness and flank geometry—a key process machine for saw blade manufacturers and resharpening service centers.

    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. JS350 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.

    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.

    Scope of Application & Limitations

    ✅ Application

    • Double-side precision grinding of carbide circular saw blades
    • Saw blade diameter 120–450mm, bore 12–105mm
    • New blade mass production (high-volume consistency)
    • Old blade reconditioning / finish grinding after tooth replacement
    • Aluminum, woodworking, PVC/plastic, metal cutting blades
    • Compatible with Kanefusa/Kinkelder/Leuco/Leitz/Freud and other blade brands

    ⚠️ Out of Scope

    • HSS saw blade grinding (requires different wheel & cooling)
    • Diamond saw blade / PCD insert grinding
    • Blades with diameter <120mm or >800mm
    • Sites without 3-phase 380V industrial power
    • Bandsaw/Frame saw blades and other non-circular tools
    • Single-side grinding only (single-side model is more economical)
    Machining Limit Note: Finish thickness tolerance ≤0.01mm and axial runout ≤0.02mm are achievable under standard conditions (constant 20±2°C, good wheel condition, trained operators). Extreme temperature fluctuation, excessive wheel wear, or untrained operation may cause deviation. Use in a temperature-controlled workshop and calibrate regularly.

    Frequently Asked Questions (FAQ)

    Q1: What is the JS350 Double Side Grinding Machine – Industrial Full-Servo Type with Robot Arm?

    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.

    Q2:What types of saw blades can JS350 grind?

    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

    Q3:What machining accuracy can the JS350 achieve?

    A: In finish grinding mode, tooth thickness tolerance ≤0.01 mm and axial runout ≤0.02 mm.

    Q4: What are the differences between JS350, JX350, DM100 and QH200? How to configure them for production?

    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.

    Q5:  What are the warranty and after-sales policies for JS350?

    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.

    Q6: Can the JS350 be used for old saw blade reconditioning?

    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.

    Q7: What site preparation is required before purchasing the JS350?

    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.

    Q8:What is the working principle of double-side grinding on the JS350?

    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. The full-servo system realizes real-time feed control (feed speed adjustable from 0.5–6 mm/s), ensuring uniform grinding removal on both sides and achieving tooth thickness tolerance down to ≤0.01 mm.
