✅ Application

• Top and face precision grinding of carbide circular saw blades
• Saw blade diameter 100–800mm, 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)

Q1: What is the QH200 Face and Top Grinding Machine?

A: QH200 is a hydraulic servo economical top & face grinding machine independently developed by Lingbang Machinery for carbide circular saw blades. It grinds both the tooth flank (cutting face) and the tooth top (outer diameter) of each tooth in a single clamping, ensuring consistent tooth geometry and stable cutting performance.

Q2: What types of saw blades can QH200 grind?

A: QH200 is designed for top and face grinding of carbide circular saw blades used in aluminum profile cutting, wood furniture processing, PVC & plastic cutting, metal sheet processing and carbide saw blade manufacturing. It is widely compatible with mainstream saw blade brands including Kinkelder, Leuco, Leitz and Freud.

Q3:What level of grinding accuracy does QH200 achieve?

A: QH200 reaches radial runout ≤0.03mm under fine grinding mode. Adopting full-servo closed-loop control and QT500 ductile iron machine base, it maintains stable precision for mass production.

Q4:What are the differences among DM100, QH200 and MCC650E?

A: MCC650E is a double-side grinder, which grinds two tooth flanks simultaneously in one clamping to control tooth thickness and flank geometry. DM100 and QH200 belong to top & face grinders, responsible for processing tooth flank (cutting face) and tooth top (outer diameter). Standard processing flow: Double-side grinding (MCC650E) → Top & face grinding (DM100 / QH200). Difference between DM100 and QH200: DM100 is full servo type with precision up to ≤0.02mm; QH200 is hydraulic servo economical model with precision up to ≤0.03mm.

Q5:What is QH200’s warranty policy?

A: 1-year full machine warranty (covers full servo components and optional imported spindle). The QT500 ductile iron machine base enjoys lifetime structural warranty. We provide free machine operation and grinding technology training, lifetime technical support (remote support; on-site service response within 48 hours), and supply of genuine spare parts throughout the equipment service life. Please email alex@lingbangjixie.com to inquire about extended warranty solutions.

Q6:Can QH200 be used for old blade reconditioning & resharpening?

A: Yes. QH200 supports both new carbide saw blade production and used blade reconditioning. The user-friendly HMI enables quick parameter switching when changing blade specifications, making it ideal for resharpening service centers processing various saw blades every day.

Q7:What site preparation is required before installing QH200?

A: Prepare the following conditions for QH200 installation: ① 3-phase 380V industrial power supply (total power: 3.8kW); ② Sufficient installation space (machine weight: 960kg); ③ Consumables such as grinding wheels. Lingbang offers installation guidance and factory layout planning suggestions.

Q8:What is the working principle of QH200 top & face grinding?

A: QH200 is equipped with high-precision spindles fitted with formed diamond grinding wheels, which separately grind the tooth flank (cutting face) and tooth top (outer diameter). Full-servo real-time feed control guarantees uniform grinding quality for every saw tooth and stable cutting performance of finished blades.
