Contact SupplierProduct Name | Horizontal Boring Machines |
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.
Â
* 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
