Cast Iron Angle Plates
Application
ZB Cast Iron Angle Plates provide a practical means for clamping and holding work in vertical position for layout, tooling and machining. Angle Plates are also used as a vertical reference for inspection and tooling purposes. They make an ideal fixture for shaping, planning, milling, grinding, drilling and boring operations.
Salient Features
Made generally as per IS : 2554 - 1971, JASH Standard Angle Plates are webbed and provided with cored slots on both working faces to facilities clamping.
Made from close grained plain cast iron conforming to Grade FG:220 of IS:210-1978.
Castings stress relieved.
Smaller sizes offered with Grades 1 & 2 accuracy and larger sizes offered in Grade 2 accuracy, as stated in table.
Hand scraped surface finish for Grade-1 accuracy. Smooth machined / rough ground / rough scraped Surface finish for Grade 2 accuracy.
Precision Angle Plates in standard sizes with accuracy as per IS:6973-1973, but made from the same patterns as those for the standard sizes as per IS : 2554 - 1971, are made upon request.
Vertical face of is T-slotted Angle Plates provided with horizontal machined T-Slots and the base / table face is having cored slots. Other constructional features are similar to those in case of standard angle plates as per IS: 2554 1971.
T-slot dimensions conform to IS: 2013. T-Slots are fixing T-Slots with tolerance H12 and are machined parallel to base and to each other within 0.1 mm per meter.
Squareness tolerances are as shown in table. Other tolerances are generally as per IS: 2554 1971. Higher tolerances for squareness as well as for T-slots can be ensured upon request.
Sizes, respective T-slot details and squareness tolerances are as stated in table. Custom sizes can be offered upon request.
