| GURU NANAK Engineering Works(Regd.) with over 4 Decades' experience, have earned an enviable reputation
as manufacturer of High Quality, Reliable & economical "KARAM" Highly Precision Horizontal Boring Machine which is a versatile Machine Tool for all types of roughing & finishing operations within the range of
BORING, MILLING, DRILLING, REAMING & FACING. It is most suitable for machining bores in various types of
Machine Bodies & Gear Boxes, for surface milling & especially for large dia flange facing. High precision
workmanship, Sturdy & well proportionate design of Castings, High powered spindle & face plate drive along
with Wide Range of Spindle Speeds & Gear Box Feeds ensure high production of accurately machined parts with
the use of both H.S. Steel & Carbide tools. The Robust & Massive construction of the machine is a guarantee to
withstand fully all the working stresses. |
| |
| * The Casting is done with the mixture of 25% Steel & Ferro Chrome etc. to acquire proper Brinell Hardness &
it is also seasoned for at least six months. The Machine is manufactured to Grade-1 Limits of ACCURACY. |
| * High Accuracy of machining due to precision scrapped/ground Guideways of Bed & Pillars etc. |
| * Fine Positioning by Dial Indicatiors & Verniers or Digital Read-Out System having an accuracy of .005 mm resolution for close manufacturing tolerances. |
| * Geometrical Accuracy of the machine conforms to Dr. SCHLESINGER'S ACCEPTANCE TEST CHART. |
| * Heavily ribbed box type Bed to withstand the Heavy Loads & Sturdy box type Columns to resist the heavy
cutting force even at elevated height. |
| * Precise Synchronized Vertical Travel of Head Stock & Boring Stay Support. |
* All traverses of X,Y & Z Axis of the machine as well as circular movement of the Work Table are
provided with automatic Feeds and Rapid Travels. |
| * All gears are precision cut on imported Mother Machinery to ensure smooth and Silent running. |
| * Manual Boring Head Height setting adjustment with a lever attached to feed gear box. |
| * Centralized control with swiveling Pendent Board for easy and convenient operations. |
| * Hand Operated knurled Knob attached to head stock drive motor and hand operated wheel attached
to feed gear box motor for the safest engagement of speeds and feeds respectively. |
* Special Attachments like Threading, Milling and Taper Boring Attachments permit to perform Multi-
Operations on a single machine. |
| * 4x90° Position of Rotary Table set with the help of an accurate adjustable stopper. |
SAFETY CLUTCHES: To Disengage: ( a) Facing Mechanism (b) Sliding Mechanism of Cross Slide
(c) Rotary Movement of Work Table ( d) Longitudinal Movement of Work Spindle.
Apart from above safety Measures, Limit Switches & suitable Shear Pins are also provided for total safety of the machine |
