1. POURNAMI TOOLS Single Pass Honing Tools

2. POURNAMI TOOLS POURNAMI TOOLS is on the business of manufacturing fine / finishing tools for the past 15 years Located in Chettiyarpatti, an industrial hub in South India, PT has good access to engineering brains and skilled man power Managed by technocrats, PT has specialized in offering custom made solutions directly to end users / OEMs

3. POURNAMI TOOLS ISO 9001:2008 certified For Design Manufacture Supply Quality Policy PT respects and implements quality at every level: Material Machines People Procedures

4. POURNAMI TOOLS Having produced customised solutions all these years, PT wants to serve the market as a whole across industries with a highly engineered standard unique tool: With that is born the tool with innumerable benefits and features, the Single Pass Honing Tool

5. POURNAMI TOOLS Single Pass Honing Tool General advantages Applicable for all types of industries Eliminates honing machine requirement avoiding huge investment Replaces other process like bore grinding & lapping Low cost of tool as compared to the benefit Achievement of high accuracy Higher productivity and lower cycle time resulting in huge savings Suitable for batch production or small series Can be performed by unskilled operator

6. POURNAMI TOOLS Single Pass Honing Tool Technical advantages Accuracy up to 1 micron tolerance can be achieved Geometrical Parameters such as Circularity, Cylindricity & Bore Straightness can be controlled by a single operation A surface finish of Ra 0.1 (even less on special request) can be achieved Expansion of tool can be achieved by simple manual adjustments by operator

7. POURNAMI TOOLS Single Pass Honing Tool Special Radial & Axial Floating Holder PT Floating Holder is used to counter the radial and axial misalignment caused between the work piece, tool & spindle PT Floating Holder adjusts the float in order to prevent bore enlargement and also helps to reduce the chatter mark PT Floating Holder ensures that the tool follows an accurate centric path Usage of PT Floating Holder enables doubling of speed & feed rate Expands equally parallel on total circumference resulting in repeated high accuracy Ensures cylindricity and circularity in microns

8. POURNAMI TOOLS Single Pass Honing Tool Floating holder collet chuck for the tool could be used on lathes, drill presses or any machine. This requires an extra or existing coolant circuit with fine filtration of up to 0.02 mm for the ultimate result The coolant has to be a very low viscous oil to avoid heat and needs a system pressure of 5 bar or less at a flow rate of 10 to 15 liters per minute to avoid heat and possible stickiness (gumminess) This holder can be mounted in any conventional machines like lathe, drilling, milling or CNC machines like CNC turning, VMC, Turn mill centers, HMC, VTL, etc For radial drilling / drill presses, Morse Taper Adaptor can be made available for side lock holders More features

9. POURNAMI TOOLS Single Pass Honing Tool Job Material Grades Made suitable for jobs of different material grades like: Tungsten CarbideGlassCeramic Hardened SteelSoft SteelStainless Steel Forged SteelCopperCopper Alloys Cast IronBrassBronze AluminiumMulti-material assemblies Hard Plastic Special note: Problems of gumminess on Aluminium & Stainless Steel can be overcome with special coating technology on our tools and oil based cutting fluid

10. POURNAMI TOOLS Single Pass Honing Tool More features Tool has a straight shank or taper shank, slotted cutting area and tool body with special coating technology The tool diameter can be increased or decreased by a threaded plunger through fine adjustments Job or tool can be floated either side by 0.1 mm to 1.0 mm Adjustment can be done without removing the tool from the machine In comparison to the other usual finishing operations, single pass honing is more suitable for thin walled jobs
