Specialist honing-equipment manufacturer Delapena Honing Equipment Ltd, Cheltenham (
www.delapena.co.uk), has launched a new high-precision vertical honing machine designed for the low- to high-volume manufacture of parts ranging from small-scale to large. The PrecisionHone (E3000S) is part of the company’s latest range of electronically controlled machines that use Siemens’ digital HMI; it can hold tolerances down to a micron (with sub-micron adjustment) and can hone diameters from 1.14 to 80mm.
Delapena says its PrecisionHone, which has automation capability, can undertake a wide range of applications, including in the automotive sector. Parts processed include turbo-charger housings, con rods, fuel-injection nozzles and electronic servos. The machine also supports the production of hydraulic-valve bodies, small cylinder liners, valve spools, water pumps and flexure sleeves.
Customised tooling and tailor-made abrasives are offered by Delapena to further extend machine capability. With quick-change tooling, the Precision-Hone offers reduced cycle times, while the control system supports conversational programming, allowing the machine to be run by both skilled and non-skilled operators.
The stroking system is capable of standard, short and single stroking for a single-pass cycle; spindle speed is fully adjustable, and the programmable feed can be set from 0.1 to 30µm per second, with incremental feed adjustment from 0.1 to 10µm (feed movement is via a ballscrew). For reduced cost and down-time, the PrecisionHone can be remotely accessed via an Internet connection.
