Cold Saw Cutting Fluid Supply and Spraying Structure Improve

In cold saw cutting, cutting fluid undertakes the functions of cooling, lubrication, chip washing and rust prevention. Unreasonable fluid supply mode and defective spraying structure will lead to insufficient liquid coverage on the cutting zone. The blade tip cannot get effective lubrication and cooling, resulting in accelerated tool wear, thermal softening of cutting edge. Meanwhile, metal chips cannot be washed away timely, scratching the workpiece surface and aggravating burr formation. Common problems include unreasonable nozzle position, uneven flow distribution, easy blockage of nozzle, insufficient fluid pressure and unstable flow rate caused by pipeline resistance loss.

The improvement of spraying structure starts with nozzle layout optimization. Multiple nozzles are arranged to aim directly at the cutting engagement zone between saw tooth and workpiece, ensuring the cutting fluid continuously covers the whole contact area instead of only spraying on the surface of workpiece. Optimize nozzle angle and aperture, select anti-clogging nozzle structure to reduce chip blockage risk. Modify the pipeline layout to reduce local pressure loss, stabilize the outlet pressure of cutting fluid.

Match the fluid supply flow rate according to workpiece material, cutting depth and feed speed. Set up adjustable flow control valve to realize on-demand liquid supply. Install filter unit on the liquid supply pipeline to filter metal fine chips, prevent solid impurities from abrading the pump and blocking nozzles. Add liquid level and pressure monitoring module to alarm when cutting fluid is insufficient or pressure drops abnormally.

Upgrade the liquid recovery and circulation system. Set up chip settling tank to separate metal scraps from cutting fluid, keep the cleanliness of circulating liquid. Regularly detect the concentration, viscosity and anti-wear performance of cutting fluid, replace or replenish liquid in time to avoid performance degradation.

After structural transformation, perform continuous cutting verification test. Observe the lubrication state of cutting area, check blade wear degree and burr size of workpiece. Adjust nozzle angle and flow parameters repeatedly until stable effect is achieved.

By improving cutting fluid supply and spraying structure, the cooling and lubrication effect in cutting zone is enhanced, chip removal is promoted, blade wear is reduced effectively, workpiece burr is decreased, and cutting quality and blade service life are improved.
