Shenoy Engg Pvt Ltd, a Bangalore based SPM manufacturers, have developed a self powered boring and facing head. The unit can be mounted on a “L” shaped bracket or boring back rest or even on a planers. It is an ideal and economic alternative for facing and boring of small diameters in large jobs, which otherwise would need expensive machines.

Mounted on a frame, the unit becomes at-site, portable machine. The unit consists of a vertical slide unit, boring head and facing head. Boring head, which is mounted on the self-powered vertical slide, permits boring, milling, etc operations. Different rotational speed rates are offered either through gears or VFD or combination of both.

The ISO-50 spindle of the boring head accommodates a detachable, self powered facing unit. Mounted in the spindle of the boring head through a ISO-50 arbor. The rotary movement to the facing unit is received through the boring unit and depth of cut in facing operation is set through the vertical slide.

Both the feed units are with their respective motors, worm reduction gear boxes, lead screws and box nuts. A common VFD provides step-less variable feed range to the axes movement. A digital display of feed movement in “mm per minute” is provided in the console.

Imported, mercury based, brushless rotary electrical joint connector will ensure smooth rotation of the power cables of the cross feed motor through the spindle without being entwined or entangled.

The male sliding surfaces are with case hardened guideway strips and the female sliding surfaces are Turcite lined. An automatic lubrication system keeps lubricating the sliding and rotating surfaces continuously. Limit switches, mounted on the adjustable dogs, facilitate pre-setting of the feed end at the desired position.

Shenoy Engineering offers full pledged SPMs with auto-cycle for batch production, which is ideal for components like valve body, pump housing etc.

Conventional milling heads with manual quill are mainly designed for milling operation. Depth of cut is set through the manual quill. Operations like drilling, boring operations are not practical through a conventional milling head for want of auto-feed to the quill. The generous clearance, inherently required in a cylindrical slide of a quill makes the feed based cutting operation less accurate and less rigid.

 

Shenoy Engg Pvt Ltd introduces affordable ram type milling head to overcome the above limitations of the conventional quill mechanism. Ram type milling heads, hitherto seen mostly on imported Plano millers, are now made available for any make of planing machines which are to be converted into Plano millers and for replacement of existing, old Plano millers. They are available with 5 HP and above capacity of milling heads.

 

The box type, square ram is guided in the housing and excess clearance in the sliding members is eliminated with the help of four taper jibs, which ensures high level of rigidity and consistent accuracy, even when the quill is extended to it’s maximum position. Combination of turcite and case-hardened guide way strips ensure a very high level of wear-resistance and make the ram slide smooth and friction-free. The quill feed is through a motor, gear box, lead screw & box nut mechanism. Step-less vertical feed of the ram movement is ensured through the common VFD (if ordered) with table & other axes feed mechanism. A scale and dog-operated limits switch mechanism facilitates depth of cut setting mechanism. If manual draw bolt is not preferred for arbor locking, EMA enabled automatic clamping & de-clamping is offered at an additional cost
