Poly Kraft Machines

We offer horizontal boring machine, which are incorporated with column, bed and saddle. We also offer horizontal facing machine. Made of qualitative castings, our range is integrated with well ribbed box-form, which helps in power transmission.

Spindle : The boring spindle is made of special steel with a super-finished surface and guided in a sturdy milling spindle in two long bronze bushes. The milling spindle rotates in two high-precision Timken taper roller bearings, automatics axial travel of boring spindle is a standard feature.
Rotary table : The table has both rotary feed and rapid circular movement as standard features. It can be clamped in any angular position as graduation of degrees are there.

We offer superior quality pillar drilling machine (all geared pillar drilling machine). These are incorporated with parts like spindle gear box, feed gear box, drill spindle and others to ensure optimum performance to the end users.
 
Features:
 
Spindle gear box : The spindle gear box has 8 mechanical speeds from 90 to 885 RPM. These are made from steel. The totally enclosed 2 H.P. motor is directly coupled with gear box. Further, the levers for changing the speed are avoided by means of providing special gear system.
 
Feed gear box: The feed gear box has 2 feed, 0.05 & 0.1 for the vertical movement of the RAM.
 
Automatic feed with auto stop : As the usual hand feed is with the machine, we provide automatic feed arrangement with it.
 
Drill Spindle: The drill spindle is made from superior quality steel. Moreover, we also provide taper roller bearing with drill spindle
 
Drill head & table arm: Both can be raised, lowered and turned round the column.

We offer radial drilling machine (All Geared Radial Drilling Machine), which are incorporated with column, bed and saddle. The detail specification is as under :

Base : The base is a one-piece casting of heavy proportion and rigidly crossribbed on the underside to prevent any bowing effect under heavy loads. A reservoirforcoolentis cast integrated with base.The 'Tee' slots on the surface are machined and the surface is handscrapped.
 
Column : It is of a high Brined Hardness number suitable for it's purpose. As there are no rotating joints there in, it is quite rigid.
 
Arm : Automatic vertical movement of Arm is provided with direct coupled flange moior on the Bracket. The lead screw will not rotate even while automatic movement will be in operation. Arm is adjustable to any angular position.
 
Drill Head : Drill Head is mounted on an Arm. The electric motor is directly mounted on drill head. Eight different speeds from 90 to 860 rpm. are obtained by changing levers. Automatic feed mechanism is provided for vertical traverse of Quill.
 
Spindle : The Toughned spindle is made of high grade alloy steel is carried in preloaded taper roller bearings to absorb reverse thrust and radial loads produced by drilling and boring. The spindle rotates and slides in ball bearings.
 
The machine is supplied with two Electric Motors. Coolent pump, Pipe fittings, Table etc. Electricals are suitable for 440 Volts, 50 cycles, 3 phase, A.C. supply. 

Attachment/or Accessories at an extra cost:
1. Double Column Arrangment with Taper Rollers Bearings on Top & Bottom.
