Drilling & Tapping Machines

Drilling Machines - Matchless Simple & Geared Model Drilling Machines
Features:

For over five decades, machless  has been in the fore front of manufacturing of Drilling and Tapping machines. MACHLESS always believes in quality. We strive to put the best components and materials so that you can get the best cutting power in your hand. We invite you to make  it A Choice Of Lifetime.

These machines are available in bench, pillar and gang type. The machine covers wide range of operations like drilling, reaming, tapping, lapping and counter boring. These machines present a unique combination of metals rigidity and accuracy for both and it’s suitability for mass production and tools room jobs.


Head:

The drilling head is of heavy duty. It is reinforced and ribbed with cast iron around bores to withstand any distortion while drilling or boring. The bearing surface is precision bored. Internal bores are honed to provide close tolerance for spindle movement. It has a mechanical locking device, which enables the head lobe raised, lowered or swung to any required position.


Spindle:

The Spindle is made of alloy steel. Spindle drives in internally broached sleeve, fitted in deep grooved ball bearings and tapper bearings. Bearings are widely supported and belt tension is not transmitted to spindle. This type of drive ensures a more efficient operation as compared with conventional single key drive.


Table:

The accurately machined table surface is provide with slots & can be adjusted vertically at the required height by means of rack and pinion set and it is also capable of revolving fully through 3600. Table can also be tilted to required angle up to maximum 45° both sides (Fig. 1 ).This can be measured with the help of a scale fitted on the rim of the arm. The table holding the arm is held at its place with the help of tapered bolts and cylindrical dowel pin locked in it’s place at its base.


Drive:

The drive to splined is transmitted through a v-belt on stepped pulley. In gear type machine additional slow speeds are obtained by engaging back gear (Fig. 2).All geared model machines are provided with additional heavy duty ball bearing for long life and better load taking capacity in the front area of front machine pulley. These and many more unparallel features are responsible for the super performance and long serving life of machless products.

Features:

“PRAKASH” 40MM Capacity, All Geared Auto Feed Radial Drilling Machine is having hase Plate, provided with in-built coolant Tank. Steel ram and pinion with 2.82 module heavy teeth enables greater load capacity.
 

Newly Designed Oil Bath Gear Box:

The all new design of gear box iii Model PMW-R4OAA, R400 and P4OAA is having 9 speed with all 9 gears of hardened NiCr steel up to HRC 50-55. Oil bath gear box and hardened gears give very long life to the machine. Rotation and easy sliding of gears in bearings gives very high reliability. Gears are internally six splined and shafts are externally

All the gears in gearbox are machined on imported WMW Germany make gear shaper.

All the splines in the gear box are machined on imported PFAUTER Germany make spline milling machine.
 

Newly Designed Autofeed Gear Box:

Autofeed gear box used in Machine R4OAA, R4OBA & P4OAA is having gears made up of NiCr Steel & of heavy 2.5 module. All gears are also hardened. Two worm gears are of heavy duty 2.82 module teeth. All the shafts in the Gear Box are supported through good quality bearings and not the Bushes. Engaging of Autofeed through TAPER GONE MECHANISM as in the lathe machines enable maximum loading capacity leaving behind other machines.

General Features :

• Main spindle and pinion made from EN steel by forging.
• Column, arm, work-head & gears made from finest closed grain cast iron; while spindle Ram trim Alloy steel.
• Main spindle run out is checked for accuracy as per IS 2199.
• For the smooth sliding of sliding arm, special 'slide-reliever-slots' are given.
• All moving parts are fine-finished with grinding to a close tolerance.
• International technic of 'Taper wedge setting'. for complete slide-setting instead of normal one point setting.
• Quality bearings with grease bath, so for permanent oiling.
• Main gear and pulley are perfectly balanced.
• Powder coated accessories for longer life and prevention of corrosion and pillage associated with usual chrome plating

Model Code System:

• P = Pillar Drill m/c
• 19/25/40 = Drilling capacity
• S = Square Head Model
• R = Round Head Model
• L = Long Spindle Travel
• A = Autofeed Model
• X = Xtra Heavy Model

Tapping Machines - Matchless Precision Gear Change Pitch Control Tapping Machine
Salient Features:

• Closed grained cast iron ribbed machine parts, inimize vibration and distortion.
• All moving parts are hardened and ground for long life.
• Bore honed to give high accuracy and close tolerance.
• Rack pinion also provided with feed friction clutch. These are designed to be idle on encounter of any obstacle or meeting any wrong point on tapping.
• Hardened change gears controls the pitch, which gives precise and rapid production of high accuracy. This reduces the set lime and increase production.
• Main spindle pulley mounted with manually adjustable safety clutch.
• The change gears are used over and over again. This way conventional lead screw and nut are replaced; which have a poor repeatability and short Life span.
• Threads are never fractured or over cut due to elimination of excessive thrust force of feeding spindle.
• Tapping strokes are adjustable for high accuracy automatic reversing which is specially important for blind hole tapping applications.
• Capacity varies according to pitch material, type of thread etc.
• Optional pully available subject to material and thread.
• Standard equipments — Electrical panel, Electrical motor, Pully, V-belt & Two set of Gears for any pitch required.
