Drill & Boring Equipments

We offer the best product range of Horizontal Floor Boring Machines, Horizontal Boring Machines, Drill Machines, Boring Machines and Drilling Machines.

Horizontal Floor Boring Machines

We have developed "KARAM" High Precision Horizontal FLOOR TYPE BORING MACHINE which is most suitable for very heavy & High Volume Jobs which can't be accommodated on the work table of conventional Horizontal Boring Machine. Such jobs can easily be handled with the Floor Boring Machine as the work-piece is kept on the Floor Plate/s provided separately with the machine. Additional ROTARY TABLE Attachment is also supplied as per customer's requirement. The design of machine is unique which ultimately provides stiffness, accuracy, precision and optimum output. The especially designed machine bed is wide enough to provide a very rigid base to the moving column. The geometrical accuracy of the machine conforms to Dr. Schlesinger's Acceptance Test Chart. The special feature of this machine is that a Variable Frequency Drive (AC DRIVE) is used for the Centralized Control of Vertical Movement of Head Stock as well as Horizontal Movement of Saddle carrying column. These infinitely variable speeds are further controlled by a potentiometer duly fitting the same on pendant board of the machine which also eliminates shifting of levers again & again. Centralized Lubrication System ensures proper lubrication to all the moving parts. Special Attachments like Milling Attachment, Threading Attachment and Taper Boring Attachments enable the machine to perform multi-operations. CNC Version of the machine can also be offered as per requirement.

Details of 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.
* 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 areprovided 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.
