Honingcraft is one of the largest honed tube suppliers in South Africa. We stock cold-drawn seamless hydraulic steel tubes sourced from the best suppliers locally and internationally.
Our tubing is available in honed or unhoned variations in popular metric and imperial sizes from 2 to 8 inches and 40 to 270 mm. If you cannot find a standard size to suit your needs, we’ll manufacture it.
Main material: St52 BK+S (E355 SR)
After cold drawing, the tubes are subjected to stress relief heat treatment.
We offer 2 types of production:
- Ready for honing tubes: ID tolerance -0,2 mm -0,3 mm
- Ready for burnishing tubes: ID tolerance -0,6 mm -0,9 mm
The tubes are cold drawn, heat treated and straightened (1/1000).
Stock changes hourly, so please contact Honingcraft to confirm the price and availability.
Honed tube is well known as the best material to manufacture hydraulic cylinders. This is because honed tubes are the most critical materials for hydraulic cylinders. Honing is essentially a bore sizing and surface preparation process.
Honingcraft is one of the largest honed tube suppliers in South Africa, stocking cold-drawn seamless hydraulic steel tubes. Their stock is sourced from the best precision manufacturing steel suppliers locally and internationally.
At Honingcraft, the process goes deeper than just honing – so to speak. Hone Tube is also the brand that Honingcraft supplies.
THE HONINGCRAFT HONING PROCESS
The Honingcraft honing process involves an abrasive cutting process. Honing uses conventional or super abrasives to cut metal chips until the bore geometry meets the specifications. By changing the grade of the abrasive, Honingcraft can create a surface finish that is optimal for a hydraulic cylinder.
To manufacture a tube with the perfect size and roundness of the bore, the honing tool needs to make multiple passes along the length of the bore. Honing produces what is widely referred to as a plateau finish.
There are much better wear resistance and sealing characteristics when using precision honing to finish inside bore surfaces, and it is, therefore, the preferred method for critical, high-performance applications like mining machinery.
