Overview
Diamond finishing for sealing surfaces
The PICCHI diamond-superfinishing range covers chip-removal machines built for a high surface finish on sealing and guiding surfaces.
DS2000 is a dedicated machine for brass and aluminium balls, reaching a roughness below 0.1 µm and producing perfect spheres or spheres with controlled ovality. DS2003 was developed for the growing production of stainless steel ball valves. Both can be set up for brass, carbon steel, stainless steel and plastic spheres up to 2½ in (external Ø 103 mm) in the basic version, with larger diameters as an option.
The DS machines have a high-rigidity spindle on super-precision bearings with hydraulic collet opening and closing, a spherical turning unit, a carriage for bevelling the through-hole, sphere centring on the rotation gap and automatic loading and unloading.
DTR 2-1/OSE is a special machine for superfinishing and diamond lapping of steering servo guide seats. DC INTEGREX is a diamond dressing module for the internal cone of gas tap bodies in brass, aluminium and bronze, integrated into PICCHI transfer machines, with Ra below 0.1 µm.
Models
Superfinishing machines shown
DTR 2-1/OSE
Special machine for superfinishing and diamond lapping of steering servo guide seats.
Applications
Surfaces finished with PICCHI diamond machines
Each model targets one sealing or guiding surface where the finish decides the part's function.
Ball valve spheres
Perfect or controlled-ovality spheres in brass, aluminium, carbon steel, stainless steel and plastic.
Stainless steel ball valves
DS2003 is designed for the production of stainless steel ball valve spheres.
Gas tap cones
DC INTEGREX diamond-dresses the internal cone of gas tap bodies inside a transfer machine.
Steering servo guide seats
DTR 2-1/OSE superfinishes and laps the guide seat of power steering units.
