Planer Machine Work Holding Devices

Planer Work Holding Devices Points : Planer Work Holding Devices, Planing Work Holding Devices, Clamping Devices, Describe work holding methods on planer, Angle plates and step blocks, Adjustable block and T-slot clamp, Planer jacks, Clamps and T-bolts, V-blocks The majority planing process is fairly easy, other than situation of a few parts frequently need extensive ability and creativity. Job might be held in a vise that has been fixed to table, but generally jobs that are small sufficient to be so held are machined on a shaper. The majority general method to hold work is to clamp it directly to the table of planer. Some points require to be considering for holding job properly on a planer. Job must not jump out of shape due to clamping pressure. Clamping must be done strictly all around work. Job must be held firmly to put off it from being shift below the pressure of cut. Job must be so held that it is probable to give a finish to surfaces that need planing. Generally used method for holding work-piece on a planer. Clamping Devices Clamping devices use for holding a work-piece on a planer.
1. Angle plates and step blocks
2. Adjustable block and T-slot clamp
3. Planer jacks
4. Clamps and T-bolts
5. V-blocks
1. Angle plates and step blocks An angle plate is an L-shaped piece of cast iron or steel accurately machined to an angle of 900. For milling certain shapes of work, the work piece can he mounted on the angle plate as a work-holding device; the angle plate is then bolted to the machine table. A step block used for holding mechanism by the help of T-bolts. One end of step block is set on work with the other end support on planer table by the facilitate of bolts.
2. Adjustable block and T-slot clamp Adjustable block consists of two jagged jaws by grooves inside. An additional kind of clamp generally use is a T-slot clamp. Bolt of a T-slot clamp is strongly bolted to table and job on table for functioning the planing process.
3. Planer jacks Planer jacks are use for supporting work-piece with leveling it on table. Generally use planer jacks are.
1. Bracing jack
2. Standard planer jack
3. Vertical jack and
4. Clamps and T-bolts Generally use way of holding job directly to table is to use clamps. There are numerous designs of clamps accessible with some trendy ones.
5. V-blocks V-blocks are used in certain milling operations to hold round work. They should be made or purchased in pairs so that one can be placed under each end of bug work. They are made with or without clamps.
