Assembly/cast iron platform Accuracy of the face is mainly flat. T-slot of the workpiece and clamp plate face is the positioning and movement between the direction of the relationship, in order to make reliable and cast iron flat face contact, its flatness is generally provided for in the concave. Countertops in all directions (vertical, horizontal, diagonal, radiation) on the straightness of the maximum values as a table surface flatness. With Rails straightness measurement method measurement method is basically the same. Available research points method, feeler gauge method, leveling instrument, optical flatness measuring instrument and method of inspection.

Cast iron platform Widely used in the construction industry, printing industry, hydraulic equipment, building construction, railway locomotives, equipment production, electronics, petrochemical, automotive, ceramic industry, railway locomotives, and other fields. In use should be avoided due to excessive wear, nicks and scratches, and the impact of plane precision and service life, under normal conditions, the life of cast iron test platform should be a long-term one. Should be cleaned after use, good rust prevention work, in order to maintain life.

Cast iron platform processing methods:
Finish planing flat cast iron welded plate placed on machine tool Workbench, you must pad the bottom of welding platform, prevent the plane perpendicular to the platform surface planing machine table, assurance of the each angle and the machine tool table full contact, platform line alignment and platform and welding machine
Fixed worktable.
Cast iron table installed in the machine tool table on stage, welding cast iron square are available on the platform side of the vertical line, draw a line on the pressure in the tool holder tool holder alignment of welded longitudinal lines on the top of the platform.
2. planing of installation: planing cast iron welding platform vertical surface Shi, used partial planing planing cut, rough planing vertical surface Shi, should put partial planing of Deputy angle loaded have big some, such cutting easy. fine planing vertical surface Shi, should put partial planing of Deputy angle installation have small some, to increased Deputy cutting edged on vertical surface of contact length, reduced welding platform processing surface of rough degrees.
3. cutting cast iron vertical steps of the platform:
1) hands shaking table knives, fixed feed depth. for ease of operation, generally cast iron machined surface of the platform to the right, left a knife cutting.
2) tool-try planing with manual vertical after 1~2mm, size, check whether the knife depth ...
3) cast iron after following a pass the entire surface of the platform to lift the turret to the starting position, square checks whether the machined surface perpendicular to the adjacent surfaces. vertical, continue planing up to the pass.
4) planing to cast iron welded platform last knife, feed should be small to avoid avalanche billet weld the platform's edge.
