planner machine

We make a rarefied range of surface Planner Machine made up of the best quality raw materials which render it toughness and durability. This heavy duty planner machine comes in numerous shapes and sizes so as to suit the specific requisites of the customers. Moreover, the machines are made available at the most affordable price range. Today, we are considered to be one of the leading planner machinery manufacturers and exporters from India. A well constructed structure with a bed, bearings, table, cross rail, tool posts, etc. has rendered high efficiency to the machine.

Construction of the Machine

Design: It is a very double rigid column and body b ore system planner fitted with ball bearings.

The Bed: The be is of deep box section type and is tied together at frequent intervals by double walled bridge pieces extending to the bottom of the bed.

The Table: It is of box section type and is streamlined with hand scraped 'V' way to bear heavy load. It is heavily ribbed and the Rack provided in it is acurately machines and milling cut.

The Bearings: The main bearings for the Gearings are cast solid with the Bed. Thea Gears Teeth are hobbing machine cut Except two gears are helical. Gun metal bearings have been provided for all the shaft and loose pulleys. Taper roller bearings can also be provided instead of Gun metal bushes.

The Cross Rail: This is of Box section type with large surface. It is suitable for both hand and mechanical drive.

Tool Posts: These are manufactured out of close grain alloy castings and steel to stand heavy cut. These can be driven both manually and mechanically.

The Uprights: The uprights are of rigid box section type. keysed firmly, bolted on to bed and are capable of absorbing the heaviest shocks without vibraion, Extra pins are provided to re-fit the machine acurately after once it is dismantled.

The Drive: The machine is arranged for direct individual as well as two belt drive

Accessories: Automatic lifting arrangements of cross rail.

QUICK RETURN CRANK MECHANISM

shaper operates by moving a hardened cutting tool backwards and forwards across the workpiece. On the return stroke of the ram the tool is lifted clear of the workpiece, reducing the cutting action to one direction only. The workpiece mounts on a rigid, box shaped table in front of the machine. The height of the table can be adjusted to suit this workpiece, and the table can traverse sideways underneath the reciprocating tool which is mounted on the ram, the table motion is usually under the control of an automatic feed mechanism which acts on the feedscrew. The ram slides back and forth above the work, at the front end of the ram is a vertical tool-slide that may be adjusted to either side of the vertical plane. This tool-slide holds the clapper box and toolpost from where the tool can be positioned to cut the straight, flat surface on the top of the workpiece. The tool-slide permits feeding the tool downwards to put on a cut it or may be set away from the vertical plane, as required.
The ram is adjustable for stroke and, due to the geometry of the linkage, it moves faster on the return (non-cutting) stroke than on the forward, cutting stroke. This action is via a slotted link or whitworth link.
Cutting fluid may be employed to improve the finish and prolong the tool’s life.
The shaping process was used in the early days of machine tools. Shaping machines are not widely used now.  Shaping produces flat surfaces by moving a single point cutting tool in a recprocating motion. The forward stroke is the cutting stroke the backward movement is completed at a faster velocity and includes the sideways feed motion.

The shaping machine is a versitile machine able to produce flat surfaces , grooves, T-Slots, dovetails, and may be used to produce curved surfaces.

The size of components that may be machined is normally limited by the length of the stroke of the shaping machine which can vary up to a maximum of about 1500mm. (750mm is normally the maximum stroke.  The shaping machine is not generally used as a production tool because of its slow cutting speed and the unproductive return stroke.
