If you're going to wholesale bulk cost-effective tobacco cutting machine bottom knife bar made in China, welcome to get pricelist and quotation from our factory. Also, customized service and OEM&ODM service are available.
Product Overview
The 3KTD84 Bottom Knife Bar is a precision-machined replacement part engineered specifically for Hauni KTH, KTC, and KT2 tobacco cutting machines. As the fixed lower blade in the cutter assembly, it works in tandem with the rotating top knife to deliver clean, consistent tobacco cuts - directly impacting cut width accuracy and overall line throughput.
Manufactured from high-speed steel and precision surface-ground to a flatness tolerance of ±0.005 mm, this knife bar maintains edge integrity even at high-speed cutting operation. A standard anti-corrosion surface treatment protects the blade against tobacco juice and the high-humidity environments typical in tobacco processing plants.
Hansheng supplies compatible bottom knife bars for a wide range of leaf-cutting platforms, including Hauni KTH, KTC, KT2, Molins MK4 / MK1, Garbuio Dickingson, and Legg RC4. Custom dimensions are available upon request with drawings or samples.

Key Product Features
Precision Surface Grinding - ±0.005 mm Flatness
3KTD84 knife bar is finished on a dedicated precision surface grinder, achieving a flatness tolerance of ±0.005 mm across the full blade length.
Material With High Strength
Superior alloy steel makes up the 3KTD84 bottom blade. It offers great wear resistance and deformation resistance following a demanding heat treatment technique. Under high-intensity running situations, it can maintain the blade sharpness and straightness for a long period.
Great Cutting Precision
To guarantee consistent and smooth tobacco cutting and reduce the loss of tobacco fiber, the blade design is totally matched with the operating trajectory of the cutting machine. Consistent cutting effect allows one to maximize raw material use regardless of coarse or fine cutting quality.
Anti-Corrosion Surface Treatment
By means of corrosion resistance, the surface of the bottom blade is coated to efficiently prevent the corrosion of tobacco juice and humid environment during manufacturing, thereby extending its service lifetime. Its structural stability guarantees that the equipment performs faultlessly in high-frequency cutting concurrently.
Can be directly replaced
3KTD84 is manufactured according to the same size as the original equipment manufacturer (we make it according to the customer's drawing requirements), making it a direct substitute for the original Hauni bottom knife bar. No gap filling, re alignment, or additional processing is required during the installation process.

FAQ
Q: How do I know when the bottom knife bar needs replacement?
A: (1) visible nicks or chipping along the cutting edge;
(2) increased tobacco fiber breakage or uneven cut width;
(3) abnormal vibration or noise during cutting. Replacement intervals vary depending on tobacco blend, moisture content, and operating hours per day.
Q: Is the 3KTD84 compatible with KT2 machines, or only KTH/KTC?
A: The 3KTD84 part code covers the bottom knife bar used across the KTH, KTC, and KT2 cutter families. The mounting geometry is shared across these models. If you are unsure about compatibility for a specific machine serial number or production year, please send us your machine model plate photo and we will confirm before shipment.
Q: What machining tolerance does the knife bar meet?
A: The 3KTD84 is produced via precision surface grinding to a flatness tolerance of ±0.005 mm. This is achieved using our in-house CNC precision grinding equipment at our facility. Tighter tolerances are available for custom orders - contact us with your technical requirements.
Q: Can you produce a custom-size bottom knife bar?
A: Yes. We accept custom orders based on customer-supplied 2D drawings or physical samples. Our CNC machining department can hold tolerances down to ±0.005 mm for standard precision requirements, and ±0.002 mm for ultra-precision specifications. Typical lead time for custom parts is 10–15 business days after drawing approval.
Q: Can you supply other Hauni tobacco cutter spare parts?
A: Yes - we maintain stock of a comprehensive range of Hauni KT-series consumables and wear parts, including top cutter knives (6KTD8-1), grinding stones (6KTC88), garniture tongue pieces, chain links, and rotary foil cutting blades. Please visit our Cigarette Machine Spare Parts category or send us a full parts list for a consolidated quotation.
