Burnishing One Blade

New machining techniques require new Tools, which in turn lead to new machining methods. This constant interaction is the driving force which ultimately leads to progress. It is this very factor that leads to continuous development of tools and machine tools. Numerical Control of machine tools represents a milestone in production methods. However the increase in operating speed now possible, together with higher precision and production automation, also places new demands on the tools. Burnishing One Blade Adjustable Reamer (BOBAR) manufactured by SUPER SURFACE TOOLS CO., MUMBAI, INDIA, may be a solution to these new requirements.
Since the beginning of cutting technology for fine machining of bores, the reaming method has proved indispensable. One of the main reasons lies in the broad spectrum of application for which this process can be used- on all machines with either rotating or stationary tools. The original HSS multi blade reamers were replaced by carbide Tipped blade reamers. Carbide tipped adjustable floating, pair of blades in a holder (SAMAR & KOYEMANN) gave fine finish. Now single blade reamers with clamped, precision adjustable blade and guide pads have put a step forward. The increasing use of NC-Controlled machines, particularly machining centers, have brought a further need for tool development which will allow new methods of increasing performance to full advantage. This need is now met by BOBAR manufactured by SUPER SURFACE TOOLS COMPANY, MUMBAI, INDIA. 
The cutting process is by means of a precision adjustable, rigidly clamped blade. At least two guide pads placed on the circumference of the head provide support and guide. In automatic production, it is vital that the chips removed do not affect the results. BOBAR’s have been provided enough chip clearance space between blades and the two guide pads. Copious coolant supply will also prevent chips affecting the results.
