For those very difficult micro-drilling applications requiring close tolerances on hole diameters, straightness, roundness and concentricity, the Levin Micro-Drilling Machine offers the best solution. It is an exceptionally accurate and sensitive machine constructed with special features to enable production drilling of small holes from 1/8" diameter down to sizes below .004" diameter.

In drilling materials which work-harden easily, these machines produce spectacular results which are just not possible on conventional drilling equipment or on machines which do not revolve both the drill and the work. Sensitive enough for use with our smallest Micro-Drills, the unique feed and alignment system, coupled with Levin Precision Collets and work-holding devices, makes the machine ideally suited for drilling miniature precision orifices, nozzles, bushings and a wide variety of instrument and electronic parts. An equally important use for such machines is second-operation drilling of small holes where the hole cannot be properly drilled initially. Second-operation drilling nearly always produces a better hole faster than it can be done initially, and this is especially true with long holes.


HEADSTOCK - The headstock is fully enclosed with special precision preloaded angular contact ball bearings. The front bearings consist of a preloaded pair of angular contact bearings with a single radial bearing in the rear. The spindle is fully hardened from end to end. On headstocks using Type 3C collets, the headstock is furnished with a special adapter and drawbar assembly which enables one to use the more accurate and sensitive Type D collets for holding work under 8.0 MM diameter.

MICRO-DRILLING UNIT -For the most precise drilling of small holes, it is essential that both the work and drill revolve, and that the drill axis be absolutely coincident with the axis of rotation of the work. By means of two adjusting slides, the axis of the drilling spindle can be quickly aligned with the headstock. The feed is accomplished by rotating the handwheel on the feed screw while maintaining pressure on the slide handle. This arrangement enables one to drill without forcing the drill since the drill cannot be advanced any faster than the hand- wheel is turned. Rapid drill withdrawal and return is controlled with the slide handle and the mechanism prevents the drill from striking the bottom of the hole.

LATHE BED - he lathe bed is cast from Meehanite and has fully ground precision ways. It has an overall length of 18-3/4" and is furnished complete with a T-Bolt, Nut and Collar assembly for attaching tooling. Pedestals are integrally cast with the bed and a T-slot is provided throughout the length of the bed ways.

AUXILIARY DRIVE - An auxiliary drive unit is included as standard equipment on all models. On machines supplied with either a Formica-top Steel Bench or a Welded Steel Cabinet, these 1/8 HP variable speed drives operate the Micro-Drilling Unit simultaneously with and independently from the main 1/3 HP spindle drive. On machines supplied without a bench or cabinet, the auxiliary drive is supplied with a double-ended motor which can be used to drive both the headstock and the drilling spindle. All drive units are foot switch operated, provide 0 to 5000 RPM on the drilling spindle, have dynamic braking, and operate off a 115 V, 60 Hz, 1 Ph AC circuit. Each model machine has a built-in switch circuit, factory-wired to accept a Levin Coolant System which will operate simultaneously with the spindle drives.

MOTOR DRIVE UNITS - Three standard drives are available for these lathes. A separate 1/8 HP variable speed drive is available for a rear bench top mounting configuration where high torque is not essential. Lathes furnished on Formica-top steel benches and lathes furnished on steel cabinets are supplied complete with a 1/3 HP SCR drive having IR drop compensation. All drive units provide infinitely variable spindle speeds from 0 to 5000 RPM with dynamic braking, foot switch start and stop, and full overload protection for use on 115 V, 60 Hz, 1 Ph AC electrical service.

CHIP TRAY - A Stainless Steel chip tray with coolant drain is included with all bench-mounted lathes, and is available at extra cost for lathes ordered without a bench or cabinet.

COOLANT SYSTEM - A coolant system is included with all models of micro drilling machines except those not including either a bench or cabinet. An independent control switch on the control unit permits simultaneous operation of the lathe and coolant system when the foot switch is depressed. An optional coolant system is avail- able for all other machines.

CABINET - The cabinet provides the best possible support for the Micro-Drilling Machine. Convenient access to all storage compartments has been provided with doors at the front and rear of the cabinet. The entire coolant system can easily be removed for thorough cleaning whenever required. All necessary wiring for both the coolant system and drive control are included with all machines on a cabinet.
