MCC650E CNC Double-Side Saw Grinding Machine(MCC650E CNC Double-Side Saw Grinding Machine) 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.
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, MCC650E meets the stringent requirements of international standards such as DIN 8083 / ISO 2935 for high-end saw blade manufacturing.

MCC650E serves saw blade manufacturing and resharpening enterprises across multiple provinces in China and overseas markets such as Southeast Asia and the Middle East:
MCC650E is a fully servo-driven CNC double-side saw blade grinding machine independently developed by Lingbang Machinery…
MCC650E is suitable for double-side grinding of carbide circular saw blades with diameter 120–800mm and bore 12–105mm…
In finish mode, thickness tolerance ≤0.01mm and axial runout ≤0.02mm…
MCC650E is a double-side grinder that simultaneously grinds both tooth flanks in a single clamping, controlling tooth thickness and flank geometry. DM100 and QH200 are top & flank grinders that grind the flank (cutting face) and top (OD). Process suggestion: double-side grinding first (MCC650E), then top & flank grinding (DM100/QH200), controlling tooth thickness and tooth-angle/OD accuracy respectively, forming a complete saw blade grinding process chain.
Machine Warranty 1 Year (including full-servo components and imported spindle), QT500 ductile-iron body with lifetime structural warranty. Includes free operation training and grinding certification, lifetime technical support (remote/on-site response within 48h), lifecycle genuine parts supply. Contact alex@lingbangjixie.com for extended warranty options.
Yes. MCC650E is suitable for both new blade production and old blade reconditioning (tooth replacement service). The full-servo programmable system stores 50+ grinding parameter sets; the intuitive HMI recalls parameters within 5 minutes per spec change, efficiently meeting the needs of resharpening centers handling many blade types daily.
When purchasing MCC650E, prepare: ① 3-phase 380V industrial power (total 4.3kW); ② installation space ≥3000×2800mm (including operation/maintenance); ③ floor load ≥1500 kg/m² (net weight 1,290kg); ④ compressed air 0.6–0.8 MPa; ⑤ grinding wheel consumables (80/100/125mm). Lingbang Machinery provides installation guidance and site planning advice.
MCC650E uses two symmetrically arranged high-precision spindles with profiled diamond wheels to synchronously grind both left and right tooth flanks in a single clamping. The full-servo system controls feed in real time (0.5–6 mm/s adjustable), ensuring equal grinding on both sides and achieving ≤0.01mm thickness tolerance.
MCC650E targets double-side reconditioning of TCT saw blades:
| Parameter | Specification |
|---|---|
| Blade type | Double-side (TCT circular saw blades) |
| Blade diameter | 120–800 mm |
| Runout | End-face runout ≤0.02 mm (thickness ≤0.01 mm) |
| Servo power | 4.3 kW |
| Machine weight | 1,290 kg |
* Figures reflect typical outcomes from Lingbang in-house regrinding deployments (clients processing 1000+ blades per month); actual gains vary by blade type and working conditions.
Selection advice: For 120–800 mm double-side reconditioning across woodworking, aluminum, and metal blades, MCC650E is the balanced choice; go robotic with JS350 for ≤650 mm automation.
