Bore finishing is a very crucial process in manufacturing of Auto components, Hydraulics valves and accessories, Aerospace components, Defense equipment etc. Day by day Bore accuracies and surface finish required is more and more precise.
In conventional Honing, the tool rotates reciprocates and expands to remove the desired material from the part bore. Controlling the bore size is difficult to achieve by this process. This demands more reliable process than conventional Honing.
One such process is Single Pass Honing OR Single Stroke Honing OR Precedor Honing OR Diamond Reaming. This is a progressive Honing Process. For example, if 60 micron material is to be removed from the bore, the part is successively passed in 6 tools pre-set with size increasing by 10 microns per tool. The part is rotary indexed after every cycle. So, after 6th parts, for every cycle one job is produced. Thus the part is finished practically in one stroke.
Single Pass honing process, as the name indicates, is just passing the honing tool once in the bore. The tools are barrel shaped and pre-set with consecutively increasing size. The tool is passed through the bore while it is rotating. Conventional honing tool reciprocates, expands while honing and retracts after completion of cycle. While Single Pass honing tool is pre-set for size, it does not have to expand and retract during cycle. It makes the conventional honing a difficult process to consistently achieve the bore size.
The tools are diamond coated, settable to a certain extent . As the tools are pre-set to the desired size and are diamond coated, the consistency of size and bore geometry are excellent. Bore accuracy to the tune of a micron can be easily achieved by this process. Also the Cp/Cpk of more than 2 is quite possible.
KHUSHBU ENGINEERS manufactures Single Pass Honing machines in India. Established in 1994, by Mr Ajeet Samani. He is a technocrat having on job experience in the field of honing. Khushbu Engineers stared the endeavor with a humble beginning of design and manufacturing of Productivity enhancing equipment. Khushbu quickly shifted the focus on Design and manufacturing of Honing Machines. It began with Manual and Auto-stroking Honing machines.
Keeping pace with the market needs, Khushbu leveraged its expertise in to manufacturing and marketing of high precision, cost - effective and efficient CNC HONING MACHINES.
Many challenges were poised in the journey to establish Khushbu as a reliable source for Honing Applications. Khushbu faced all the challenges with complete technical support and preparedness to spend on R & D.
Khushbu Honing Machines are extensively used by the leading names of industries like Godrej, MICO, Indo MIM, Eaton, Preciforge and Gears, Bajaj Motors etc. The product spectrum includes two wheeler transmission Gears, a high production and highly accurate Auto component to Hydraulic Valves, having L/D ratio of more than 5 and demanding highest accuracy of bore geometry. Varieties of components are honed with ease of operation achieving very high accuracy and production requirements.
Applying single pass diamond honing technology, extremely close tolerances can be achieved consistently in mass production at a lesser per piece cost. Diamond-plated finishing tools are capable of achieving micron/sub-micron accuracy.
Two of the renowned companies have joined hands with Khushbu recently. Kenrie Inc, USA and Auteco Srl, Italy. Both are leaders in special applications of Bore finishing.
Khushbu has exported machines to USA, China, Europe, Middle East and South Africa.
Khushbu always welcomes challenges in bore finishing.
