The honing mandrel design incorporates a single stone slot to locate the honing stone and the expansion wedge to provide movement of the honing stone. Unless otherwise stated all mandrels are supplied with an expansion wedge for open hole work and, unless otherwise stated, can be modified for blind hole work.
From diameter’s 12mm and above mandrels cam be used manually in a power tool or on a machine like a PowerHone by using a CG100 adaptor.
CCS Type – Range Ø1.14 - 3.05mm
A tubular honing mandrel designed for use with the 1651 collet adaptor. The entire mandrel body is hard chrome plated for increased life. These mandrels are NOT supplied with wedges and these must be ordered separately. CCS mandrels are NOT suitable for blind hole work. Note; only "super abrasives" can be used on CCS type mandrels
HS Type – Range Ø3.05 – 25.91mm
A range of hardened steel mandrels, available in a choice of short and long series working lengths, for general honing use and essential for honing abrasive and hard materials. Mandrels up to Ø6.22mm have a fully circular workhead. Above this diameter the unique three point workhead design eliminates chatter and ensures rapid correction in errors of roundness.
SS Type – Range Ø6.22 – 15.62mm
A range of soft steel mandrels incorporating the same design features as the HS type. These mandrels are used for honing pick up prone materials and are particularly suitable for super finishing of most materials.
B Type – Range Ø3.05 – 15.62mm
A range of bronze mandrels incorporating the same design features as the HS type. These mandrels are used for honing pick-up prone materials and are particularly suitable for super finishing of most materials.
PT Type – Range Ø15.62 – 79.4mm
A range of honing mandrels incorporating the unique three point workhead design and consisting of a permanent mandrel body fitted with a replaceable guide shoe. When the shoe is worn out it is simply removed and a new shoe fitted. Used for similar applications to the B type and for all holes above Ø25.4mm. Available in short, long and extra-long series. If mandrels above Ø25.4mm are required for blind hole work this must be stated at the time of ordering.
HSK Type – Range Ø6.22 – 25.91mm
A range of hardened steel mandrels designed specifically for honing bores containing standard ISO keyway slots. Based on the HS type design but with two or more abrasive sticks mounted side by side on the stone holder giving an overall stone width of approximately twice that of the keyway. These mandrels are available in short series working length only and are NOT suitable for blind hole work.
PTK Type – Range Ø15.62 – 66.68mm
A range of permanent type mandrel bodies incorporating the same design features as the HSK type, and fitted with replaceable cast iron shoes that must be machined to the specific diameter to be honed. These mandrels are available in short, long and extra-long series working lengths and are NOT suitable for blind hole work.
Multi stone honing tools using Delapena vertical stone sets
Delapena vertical tooling heads have been adapted to be used on horizontal honing machines. This gives the user an alternative honing option on smaller diameters (25-79mm) and capability to hone bores above the range of the Delapena mandrel tooling (>79mm).
