CF-100P vs CF-200P — Know Your Machine Before You Set It Up
CNFLEX offers two automatic hose cutting machine models — the CF-100P track-feed and the CF-200P conveyor belt. Their operating principles differ in ways that directly affect how you configure and operate each one. Understanding the distinction upfront prevents common setup errors.
CF-100P
Precision planetary stepper motor + pneumatic blade actuation. Purpose-built for high-volume production of rubber tubes, PVC hoses, layflat hose, and rigid flexible pipe.
CF-200P
Dual-motor 4-wheel conveyor belt feeding. Optimised for soft, flexible, and irregularly shaped materials where traditional roller feeding causes deformation.
Step 1 — Pre-Installation: Site Preparation
Both the CF-100P and CF-200P weigh 45KG. Their compact footprints (560×460×480mm and 650×380×380mm respectively) allow benchtop or floor-stand installation. Before unpacking, verify the following site conditions.

Step 2 — Match the Right Model to Your Material
The CF-100P and CF-200P are each optimised for different material types and production scenarios. Running the wrong model for a material leads to cut face quality issues, feeding problems, and unnecessary wear. Use the table below to confirm you have the right machine before configuring any parameters.
Step 3 — Programming the Key Cutting Parameters
Both models feature a bilingual (CN/EN) 128×64 LCD control panel with one-key language toggle. The CF-100P and CF-200P share the same core parameter structure. Getting these right before starting a production batch is the most direct lever for achieving the ±0.2% precision the CF-100P is rated for.
Cut Length
The CF-100P accepts any length from 0.1mm to 99,999.9mm in 0.1mm increments. The CF-200P covers 0.1mm to 9,999.9mm. Input your target length, then run 5–10 trial cuts and measure with a vernier calliper. Rubber compounds have varying degrees of springback after cutting — record the actual measured offset for each hose type and save it as part of the job profile so repeat orders do not need re-calibrating.
Feed Speed
The CF-100P feeds at up to 700mm/sec, achieving a maximum of 100 cuts/min at 50mm cut length. The CF-200P operates at 1–40 m/min and is continuously adjustable. Both models support auto/manual mode switching. For soft rubber materials, start at 60–70% of maximum speed to avoid stretching ahead of the measurement point — increase incrementally while monitoring length consistency across 20+ consecutive pieces.
Batch Count & Segment Scheduling
Both models support total count preset, batch pause, and segment scheduling — the machine stops automatically when the programmed count is reached, enabling fully unattended production runs. Use the sub-count (segment) function to divide large orders into packaging-ready groups — for example, cut 2,000 pieces in segments of 100 with automatic pause between groups. The running total and segment count are both displayed on the LCD at all times.
Blade Stroke — CF-100P
The CF-100P blade stroke is adjustable between 1mm and 55mm. Set the stroke to just exceed the hose outer diameter — there is no benefit to running a longer stroke than the material requires, and excess stroke increases cycle time and mechanical wear. For example, a 20mm OD hose should use a stroke of approximately 22–25mm, not 55mm.
Cutter Height & Delay Time — CF-200P
The CF-200P features an adjustable cutter height (0.1–40mm) to accommodate different material thicknesses. Set the height to match your material’s cross-section before starting. The delay time between cuts should allow the blade to fully retract and the conveyor to reach stable feeding speed before the next cut — for high-elasticity silicone or soft rubber, a 0.2–0.5 second delay prevents partial separation at the cut point.
Multi-Lane Cutting — CF-100P
The CF-100P supports dual-row or multi-strand simultaneous cutting. When running multi-lane, ensure all material strands are the same OD and are fed under equal tension — unequal tension across lanes is the primary cause of length variation in multi-strand cutting. Speed and length remain continuously adjustable in multi-lane mode. Total cut count accumulates across all lanes combined.
Step 4 — Verifying Cut Quality in Production
The CF-100P is rated at ±0.2% cut precision under microprocessor-controlled stepper motor drive. In practice this means a 500mm hose length should fall within ±1mm of specification. The following inspection points confirm you are achieving the machine’s rated precision.
📏 Length Check
Measure 5 pieces from every 200-piece batch with a vernier calliper. All should fall within the ±0.2% tolerance of the programmed length. Systematic drift in one direction (all consistently shorter or all consistently longer) indicates feed slippage or a calibration offset that needs correction — it is not random variation.
✂️ Cut Face Quality
The CNFLEX machines use proprietary blade geometry combined with dedicated control software specifically to eliminate ragged edges. If tearing or smearing appears on the cut face, the blade requires replacement. The black steel cutting blade supplied with the CF-100P is the reference blade for rubber and PVC — use only the specified blade type.
📐 Squareness
Place the cut end on a flat reference surface — there should be no rocking. An angled face indicates the material moved fractionally during the cut. On the CF-100P, check that the limit fixture clamp is correctly positioned and that clamp force matches the material hardness.
🔍 LCD Count Verification
The 128×64 LCD displays the running cut count and batch progress in real time. Cross-check the displayed count against a physical batch count at the end of each segment — occasional missed counts due to feed sensor activation are detectable this way before they accumulate into a full-batch discrepancy.
Common Problems and How to Fix Them
Maintenance Schedule — CF-100P & CF-200P
Consistent preventive maintenance is what keeps the CF-100P and CF-200P operating at rated precision. The following schedule is structured for machines running a single or double production shift and should be used alongside the Maintenance Manual supplied with each machine.
- •Clear rubber swarf and hose particles from the cutting zone, blade, and guide channels
- •Wipe feed rollers (CF-100P) or conveyor belt surface (CF-200P) — rubber residue causes feed slip
- •Visually inspect the black steel blade — replace if cut face quality declined during the shift
- •Check that the limit fixture clamp is secure and undamaged
- •Lubricate blade guide rails and cam mechanism per the Maintenance Manual specification
- •Check feed belt tension on CF-200P — loose belt causes length variation under load
- •Run a 10-piece calibration check: programme 100mm, cut 10 pieces, measure all 10 with calliper
- •CF-100P: verify pneumatic pressure at air cylinder — check for air line leaks at connection points
- •Full clean of motor driver unit ventilation slots — rubber dust accumulation causes overheating
- •Inspect the 128×64 LCD display connector — reseat if display shows intermittent flicker
- •Check all electrical connections on the main control board for corrosion or heat discolouration
- •Back up all saved job parameter profiles to external storage before any firmware update
- •Review the User Manual and Maintenance Manual for any manufacturer-specified interval tasks
Frequently Asked Questions
What is the smallest cut length the CF-100P can produce?
The CF-100P supports a cut length range of 0.1mm to 99,999.9mm in 0.1mm increments. In practical terms, very short cuts below 5mm require careful calibration of the delay time setting to ensure each piece fully separates and clears the cutting zone before the next feed cycle begins.
Does the CF-100P require a compressed air supply?
Yes. The CF-100P uses pneumatic (air cylinder) blade actuation — a compressed air supply is required at the installation location. The CF-200P is fully electric and does not require compressed air. If your site does not have an air supply, the CF-200P is the appropriate choice for soft and flexible rubber hose materials.
Can the CF-100P cut multiple hoses simultaneously?
Yes. The CF-100P supports dual-row and multi-strand simultaneous cutting. All strands must be the same outer diameter and fed under equal tension for length consistency across lanes. The cut count displayed on the LCD accumulates across all lanes combined.
What cut precision does the CF-100P achieve?
The CF-100P is rated at ±0.2% cut precision under microprocessor-controlled stepper motor drive. For a programmed length of 500mm, this means a tolerance of ±1mm. Achieving this specification consistently requires correct feed speed settings for the material, a sharp blade, and stable feed tension from the hose reel.
Which model is better for silicone tube and soft corrugated hose?
The CF-200P is the correct choice for silicone tube, corrugated tube, seal strips, and other soft or irregularly shaped materials. Its dual-motor 4-wheel conveyor belt feeding system provides a larger contact area than roller feeding, minimising deformation of soft profiles. The adjustable cutter height (0.1–40mm) and wide cutting range (0.1–140mm width) accommodate virtually all soft tube profiles.
Can the machine run unattended overnight?
Both models support unattended batch production via the automatic count preset, batch pause, and material-absence auto-stop functions. When the programmed count is reached or the hose reel runs out, the machine stops automatically. Verify the reel has sufficient material for the full batch count before starting an unattended run.
