📌 Core Summary

QH200 CNC Saw Blade Top & Face Grinding Machine (Hydraulic Servo Economical Model) is a high-precision CNC grinding equipment for carbide circular saw blades independently developed by Dongguan Lingbang Machinery Technology Co., Ltd. It can independently complete all grinding processes in one setup, including top grinding, face grinding, trapezoidal tooth grinding and form grinding. Under fine grinding conditions, its radial runout accuracy reaches ≤0.03 mm (30 microns). Compatible with carbide circular saw blades ranging from 100 mm to 800 mm in diameter, the machine is widely applied in solid wood furniture processing, aluminum alloy profile cutting, metal saw blade resharpening, and complete production lines for carbide saw blades. The machine is equipped with a servo feed system featuring servo feeding, servo-driven worm gear angle adjustment, hydraulic tooth shifting and hydraulic clamping. It supports digital angle setting and delivers consistent repeat positioning accuracy for mass production. An optional imported precision spindle is available with a 24-month warranty, compared to the industry standard 12-month warranty, which fully demonstrates the outstanding durability of core components.

✅ 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 an (economical) hydraulic servo gear tip and tooth surface grinding machine independently developed by Lingbang Machinery, specifically designed for the grinding of carbide circular saw blades. This equipment can complete the grinding of tooth surfaces and tooth tips (outer diameter) in a single setup (with only the grinding wheel needing to be replaced), ensuring consistent tooth profiles and stable cutting performance. It is the most cost-effective grinding equipment choice for saw blade sharpening service providers

 

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.It is a cost-effective product for saw blade regrinding， 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.
