Universal drilling machine It has wide range of 15-speeds and 6-power feeds makes the machine suitable for drilling, tapping, reaming operations within its full working range and various positions of arm and drill head.This machine is designed for drillling, reaming and tapping operations on components of large machine tools and forming machines, turbines, generators, compressors, different kind of steel constructions, boilers, containers, chemical equipments, furnases of cement plants, ship building, etc.

PC-CNC Controller enables to use EMC2 standard G-Codes for 3D operations & Print Command from any favorite application for 2.5D Engraving operation. The controller can process any design of 3D G-codes using USB controller.Preset but expandable material menu, positioning of a job, keyboard controls for axis moves, Z surfacing, home switch handling, flexible start position, accelerationdeceleration setup and control, spindle motor onoff control, and easy controls for speed, depth and dwell.

Portable drilling machine which is designed to offer rigidity, precision and flexibility to drill at any angular direction. The drill head swivels on 2 planes - 90 Up & 90 Down, and its 360 rotational movement makes possible the drilling operation at any angular direction. The model UR50 is having 50-mm drilling capacity in steel.

Neat and clean cutting.Fast and accurate process.Feed rate of cutting torch can be adjusted to get maximum output, hence less gas consumption achieved.In mass production, repeatability of job achieved. That is not possible in manually profile cutting machine. It increases productivity.By using NESTING software, maximum utilization of material is possible. It reduces cutting time and scrap.Gas consumption is less by adjusting flow and pressure of gas.Complicated job having sharp edges and accurate dimensions can be achieved easily, which are not possible by manual process.

Heavy Duty - 50-mm drilling in steel.Wide range of 8 spindle speeds for drilling, tapping, reaming and boring operations.Five auto power feeds: 0.05 to 0.25-mm per revolution.Auto feed disengages at preset depth as well as too high or abnormal drilling pressure.Hardened and lapped alloy steel gears fitted on splined shafts in main drive gearbox runs in an oil bath.Hardened and precision ground spindle sleeve.Double column construction for rigidity and effortless centering.Arm and drill-head guide ways are precisely hand scraped for minimum play and rigid clamping of drill-head with the arm.Well adequately ribbed base-plate, inner column & arm for maximum rigidity and minimum deflection.

Heavy Duty 40-mm drilling in steel.Wide range of 8 spindle speeds for drilling, tapping, reaming and boring operations.Five auto power feeds: 0.05 to 0.25-mm per revolution.Auto feed disengages at preset depth as well as too high or abnormal drilling pressure.Hardened and lapped alloy steel gears fitted on splined shafts in main drive gearbox runs in an oil bath.Hardened and precision ground spindle sleeve.Double column construction for rigidity and effortless centering.Arm and drill-head guide ways are precisely hand scraped for minimum play and rigid clamping of drill-head with the arm.Well adequately ribbed base-plate, inner column & arm for maximum rigidity and minimum deflection.

Features

• All major parts are made of graded cast iron FG260 grade duly stress relieved.
• C3 class precision ground ball screws and nuts for all three axes.
• Precision heavy-load-duty LMG (HIWIN/PMI or any reputed make).

• Yinsh make precision lock-nuts for all axes.
• Precision double angular contact matched pair ball bearings at front and a single at rear of ball screws.
• Automatic lubrication system of 110cc/min capacity.
• X-axes (table movement) is fitted with telescopic metallic covers and Y-axes is protected with organ type bellow covers.
• Accuracy & Test Chart

  Following reports will be provided along with the machine:

  • Axis Calibration Report by LASER interferometer
  • Angle Deviation Measuring Report by Reinshaw
  • Geometrical Accuracy Report

Highlights

• AR Seriesof radial drilling machines are characterized by their easiness in operation, powerful drilling performance, high precision and rigidity. They provide robustness, efficiency and dependability in one-off and batch production environment.
• The machines are double column type having generously provided ribs and appropriate wall thickness for base-plate, arm, inner column & column sleeve and are rigidly built to withstand static as well as severe dynamic loads.
• It is double column design and wide clamping area of base-plate with ample rigidity of the machine makes it suitable for drilling, tapping and reaming operations.
• Its drill-head comprises of an oil-filled sturdy gearbox and a power full feed box, which offers 8-speeds and 5-auto feeds. Auto feed is fitted with a ball clutch, which disengages at preset drilling depth as well as against too high drilling pressure, thus prevents breakages or damages of internal moving parts.

Applications

The machine is suitable for one-off or for batch production. It finds application in tool-rooms, engineering & fabrication shops, manufacturing of dies, moulds & machineries, automobile & ship building industries, railways, defense and bridge construction.
