BLT310 Consumables: What Should You Keep in Stock?
The BOCHU BLT310 is a smart fiber laser cutting head designed for laser power up to 4 kW, with F150 and F200 focal length options. Its consumables and replacement parts should be selected according to the exact head configuration.

The nozzle thread, ceramic specification and part-number compatibility above are based on BOCHU's consumables catalogue and product listings. Cartridge assemblies are not the same as the optical windows installed inside them. Confirm the exact window dimensions and optical specifications before purchasing replacement glass.
2. Recommended Spare Quantities for One BLT310 Machine
The quantities below are practical starting recommendations, not official BOCHU stocking requirements. Adjust them to cutting hours, material mix and delivery lead times.
| Spare part | Suggested starting stock |
|---|---|
| Commonly used nozzles | 10–20 pcs for each caliber, mixed orifice sizes |
| Protective lens | 50–100 pcs per frequently used |
| Ceramic bodies | 5 pcs |
| Ceramic locking rings | 1–2 pcs |
| Spring seals and other sealing parts | 2–4 pcs per applicable type |
| Correct protective-window cartridge or cover | No need |
| Focusing Lens unit | 1-5 sets, depending on downtime risk |
| Collimation Lens unit | 1 set |
| Capacitance sensor module | No need |
For a low-volume workshop, start with nozzles, protective windows and ceramic parts. A high-volume cutting shop or distributor may need a larger stock of frequently used items. Expensive assemblies and electronic modules can usually be stocked more selectively.
3. When Should BLT310 Consumables Be Replaced?
- Nozzles: Replace when the orifice is damaged, deformed or contaminated, or when cutting quality becomes unstable.
- Protective windows: Inspect regularly and replace if contamination, scratches or thermal damage cannot be safely resolved.
- Ceramic body: Replace if cracked, chipped or unable to maintain reliable nozzle mounting and sensing.
- Seals: Replace when damaged or when sealing problems are identified.
- Cartridges and sensor modules: Replace only when inspection or diagnosis indicates a fault.
There is no universal replacement interval. Actual service life depends on cutting conditions, material, assist gas, maintenance and operating hours.
4. How to Order the Correct BLT310 Replacement Parts
Before placing an order, confirm:
- Head model: BLT310, not BLT310T.
- Focal length: F150 or F200, especially for cartridge assemblies and related parts.
- Nozzle thread: Single layer or double layer, and caliber
- Part number and dimensions: Match the existing component and the manufacturer's documentation.
- Optical window position: Identify the upper, lower or second-lower position where applicable.
Do not select a part based on appearance alone. Some BLT-series components look similar but are not interchangeable.
