📌 Core Summary

DM100 CNC Saw Blade Top & Face Grinding Machine is a high-precision CNC carbide circular saw blade grinding equipment independently developed by Dongguan Lingbang Machinery Technology Co., Ltd. It can independently complete top grinding, face grinding, trapezoidal tooth grinding and form grinding. The radial runout accuracy can reach ≤0.03mm (20 microns) in fine grinding mode. It is suitable for carbide circular saw blades with a diameter of 120–650mm, and widely used in wood furniture manufacturing, aluminum alloy profile cutting, metal saw blade regrinding and carbide saw blade production lines. The equipment adopts a full servo drive system — servo feed, servo + worm gear angle adjustment, servo automatic shifting — to realize digital parameter storage and repeat accuracy for mass processing. Compared with traditional grinding solutions that require multiple machines for separate operations, the DM100 can finish all grinding processes in a single clamping on one machine, reducing cycle time by up to 40%. Optional imported precision spindle with 24-month spindle warranty (industry average is 12 months), fully reflecting the reliability of core components.

The DM100 is a full-servo CNC grinding machine dedicated to high-precision grinding of tooth tips and tooth flanks on TCT circular saw blades. All tooth tip and flank grinding operations can be completed in one single clamping setup only by replacing different grinding wheels. It accurately controls tooth sharpness and saw blade concentricity, making it core processing equipment for saw blade factories and professional saw resharpening centers.

According to the industrial standard JB/T 5735-2018 Woodworking Tungsten Carbide Tipped Circular Saw Blades, the radial runout of a saw blade is the core indicator for judging cutting precision and workpiece surface quality. After processing on the DM100, the saw blade radial runout tolerance is controlled within ≤0.02 mm, fully complying with strict international standards for high-end saw blade production such as DIN 8083 and ISO 2935.

Kinco touch screen with intuitive operation. After free training, new operatorscan operate independently within an average of 2 hours, without professional CNC programming background.

Servo tool setting, angle adjustment (-15° to +30°), tooth indexing and feed (0.5–6 mm/s), four-axis fully digital closed-loop control, repeat positioning accuracy ±0.005mm.

Tensile strength ≥500 MPa (GB/T 1348-2019), with vibration damping about 40%, better than ordinary gray cast iron, excellent dimensional stability, body covered by lifetime structural warranty.

High-precision, high-strength, high-rigidity imported spindle, radial runout ≤0.002mm,, ensuring consistent long-term grinding quality.

Multiple reciprocating grinding programs, open and programmable, supports storing 50+ sets of process parameters, spec change within 5 minutesto complete recall, flexibly configure process parameters.

Fully enclosed guard design, complies with CE machinery safety standard,, effectively controlling grinding dust and noise, ensuring operator safety and a clean workshop environment.

✅ Application

• Top and face precision grinding of carbide circular saw blades
• Saw blade diameter 120–650mm, 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)

Q: What is the DM100 Face and Top Grinding Machine? A: DM100 is a servo-driven top and face grinding machine independently developed by Lingbang Machinery for carbide circular saw blades. It grinds both the tooth flank (cutting face) and the top (outer diameter) of each tooth in a single clamping, ensuring consistent tooth geometry and cutting performance. Q: What types of saw blades can DM100 grind? A: DM100 is designed for top and face grinding of carbide circular saw blades across aluminum profile cutting, woodworking furniture, PVC/plastic processing, metal sheet cutting and carbide blade production. It is widely compatible with mainstream blade brands such as Kinkelder, Leuco, Leitz and Freud. Q: What level of grinding accuracy does DM100 achieve? A: DM100 achieves top/end face grinding accuracy within 0.03mm in routine operation, with high-precision grinding wheels and processing progress of ≤ 0.02mm for the object. It adopts full servo closed-loop control and QT500 ductile iron body to ensure consistency in batch production. Q: Difference between DM100 and MCC650E/QH200? A: MCC650E is a double-side grinder that grinds both tooth flanks simultaneously in one clamping, controlling tooth thickness and flank geometry. DM100 and QH200 are top & face grinders that grind the flank (cutting face) and top (OD). Typical process: double-side grinding first (MCC650E), then top & face grinding (DM100/QH200). Q: What is DM100’s warranty policy? A: Machine Warranty 1 Year (including full-servo components and imported spindle), QT500 ductile-iron body with lifetime structural warranty. Includes free operation and grinding training, lifetime technical support (remote/on-site response within 48h), lifecycle genuine parts supply. Contact alex@lingbangjixie.com for extended warranty options. Q: Can DM100 be used for old blade reconditioning? A: Yes. DM100 suits both new blade production and old blade reconditioning. The full-servo programmable system stores multiple grinding parameter sets; the intuitive HMI recalls parameters within minutes per spec change, efficiently serving resharpening centers handling many blade types daily. Q: What supporting conditions when purchasing DM100? A: When purchasing DM100, prepare: ① 3-phase 380V industrial power (total 4.5kW); ② adequate installation space (machine weight 1080kg); ③ stable compressed air 0.6–0.8 MPa; ④ grinding wheel consumables. Lingbang provides installation guidance and site planning advice. Q: What is the principle of DM100’s top & face grinding? A: DM100 uses high-precision spindles with profiled diamond wheels to grind the tooth flank (cutting face) and top (OD) respectively, with full-servo real-time feed control ensuring uniform grinding quality on every tooth and stable cutting performance.
