The Stiles Hydro-Bore series includes the same high quality standards and features as the smooth-bore series but also offers additional benefits for a higher speed and more accurate
performance.
Our advanced steel construction offers many advantages compared to typical sealed systems:
- Construction allows a higher pressure (300-350 bar) to be used evenly down the length of the spindle which in turn allows increased torque transmission between cutterhead
and spindle.
- The increased torque means less chance of slippage, therefore better surface finish and increased efficiency of the machine.
- The advanced construction has less likelihood of leakage occurring due to wear in a sealed system, therefore less likelihood of incurring machine downtime or damage due to loss of pressure.
Standard lengths, angles, bores, and knife slots are offered. Other sizes are available on request.
Using a torque wrench, tighten all screws to 25-30-ft-lbs torque, in the correct sequence, from the center to the outside of the cutterhead.
The use of safety collars is required to afford the protection of safe and positive drive if pressure in the block is not present. Two types are available:
- Threaded safety collars- to be used with tooling using maximum capacity on the spindle length.
- Plain safety collars- to be used with tooling using less than maximum capacity on spindle length.
Ensure that the cutterhead bore and spindle are clean and free from burrs or deep scratches. The efficiency of the friction drive is determined by the quality of contact between the cutterhead bore and the machine spindle. Failure to ensure clean conditions may cause a reduction in the power transmission properties of the cutterhead.
The cutterhead must never be pressurized unless mounted on the machine spindle or grinding arbor, as distortion of the inner sleeve may occur.
Operating Pressure is 300-350 bar.
Check pressure daily, using grease pump before operating machine.
Release valves must be left open if the cutterhead is immersed in a cleaning tank or not used.
Maximum Speed:
- 8300 rpm for 137mm body diameter cutterheads
- 7200 rpm for all other cutterheads
