Jet Spindles

Standard spindle machining runs at only 6,000-15,000 rpm; 15-70 bar coolant pressure pushes the tool up to 55,000 rpm and saves 70% of machining time

Interfaces available: BT / HSK / ER / PSC systems and straight shank

ATC tool change, no orientation required

Chip transmission displays the actual tool speed

Excellent accuracy to 0.003 mm

Spindle speed is the most common bottleneck for small tools: a 2 mm end mill often needs 20,000-30,000 rpm to reach its recommended cutting speed, while most machining-centre spindles top out at 6,000-15,000 rpm. Too little speed means abnormally fast tool wear, a surface finish that will not improve, and longer cycle times

No external power needed: coolant goes in to drive the turbine and comes out flushing the chips, so drive and cooling are done in one pass; the spindle does not turn, so bearing load is lower than with a mechanical unit

Common applications: mould detail machining, engraving, small-hole drilling and thread milling, as well as face milling, drilling, grinding, thread cutting, chamfering and fine engraving

Micro-diameter speed increasers are also available in 0° and 90° types, for Swiss-type, gang-tool and turret lathes

When it is not suitable: if the machine has no through-spindle coolant or the pressure is too low, a pneumatic unit is needed instead; where a long projection is required or the tool diameter is already large, running the spindle directly is more efficient; high coolant temperature or large particles will shorten turbine life

Before requesting a quotation, please provide: machine brand and model with spindle spec, through-coolant pressure and flow, whether ATC tool change is required, tool diameter and clamping method, target rpm, and the operation and workpiece material
