Precision Engineering Products

We are leading supplier of Microflat Universal Bench Center. For checking Concentricity, Parallelism, Axial Run-out, Taper Angle and Taper form. Sine Rollers allow quick and easy taper Angle and Taper form measurements in conjunction with Gauge Blocks. It can also be used for layout work, in conjunction with indicator Stands and Surface Plates. Removable Centers, for mounting extra long parts directly on v-ways.

This Surface Plates with Center Attachment can be used as a Precision Inspection Bench Center as well as a Surface Plate (two-in-one) with high Grade of accuracy. Material of construction and accuracy parameters asper IS-2285-2003 for Cast Iron Surface Plate, IS-7327-2003 for Granite Surface Plate and IS-5980-78 for Center Attachments

Single Sided Flat Lapping Machines are single Plate Machines available in various Models suitable for vast majority of Lapping applications including high stock removal, ultra hard materials, precision work to light band tolerances.

Advantage:

• Operationally fast, with high degree of repetitive results with no extra skill.
• Stressing of jobs eliminated as no holding force is required
• Odd shapes and different materials all can be lapped to a fine finish of 0.6 µm CLA and flatness to one light band.
• Variety of materials such as Cast Iron Soft/Hardened Steel, Stainless Steel, Bronze, Aluminum, Carbon, Plastics,
• Ceramics, Tungsten, Silicon, Stellite, Ferrite, etc. can all be lapped.

Typical Applications:

• Mechanical seals, Piston Rings,Compressor Components, Pumps & Valves Components, Hydraulic Components, Gauge Blocks, Precision Spacers, Metal Cutting inserts, Bearing Races, Springs, Slitter knives, Fuel Injection Components, Ceramic, Seal & Valve components, Quartz Crystals, Precision Optics, Optical Flats, Metrological/Measuring instrument components and so on.

We are offering of Microflat Cast Iron Box Angle Plates. Useful as a versatile tool for layout, machine set-ups, tooling and inspection. Can also be used as right angles or squares. Matched pairs can be used as parallels and height blocks. A job can be fixed with one of the faces and rotated in five planes without the need for repositioning or disturbing accuracy.

Features:

• Made generally as per IS-6232-71 in Grade-1 and Grade-2 accuracies with hand-scrapped surface finish.
• Made from high duty close grained Castings conforming to Grade FG-220 of IS-210. Castings duly stress relieved.
• Machined T-slots on one face and cored elongated slots on four opposite faces provided for clamping purpose.
• Matched pairs can be offered on request at extra cost.
• Precision Box Angle Plates as per IS-6985-1973 having tolerances approx. half of those mentioned in the table can be made on request at extra cost.

Other details:

• Test Mandrels are mainly used for Machine Tool Acceptance Test.
• Test Mandrels are made generally as per IS-2063-2002.
• Made from good quality alloy steel, heat-treated for maximum stability and wear resistance.
• Test Mandrels Metric, SK, BT, HSK & other series offered on request.
• Provided with teak-ply storing case on request at extra cost.

These are used in Machine Shops for set up and Machining operations, building up height of work on Machine Tables and for mounting work for scribing and inspection. Microflat Granite Parallels being rust proof are preferred where coolants are used.

Features:

• Working faces offered duly precision hand-lapped finish
• Granite Parallels offered in matched pairs
• All the four longitudinal sides offered flat parallel

Dimensional and Technical features same as that of Cast Iron T-Slot Angle Plates as per IS-2554-71 but vertical face is provided with horizontally Machined T-slots and the base/table face is having cored slots.

T-slot details are as under:

Microflat Cast Iron Straight Edges are widely used for setting up and leveling machinery and for checking and spotting bearing surfaces during hand scrapping operations. Properly supported, they may be used with various indicating devices to check surface flatness of large Machined areas like Surface Tables, Machine Tables & Beds, Machine guide ways, etc.

Salient Features:

• Made from close grained plain Cast Iron Castings conforming to Grade FG-220 of IS-210. Casting duly stress relieved.
• Table top and base are flat and parallel within 0.05 mm per 300 mm
• T-slots are parallel to the edge of the table and the cylindrical base within 0.05 mm per 300 mm.
• T-slots parallel to the edges within 0.05 mm per 300 mm

Cast Iron Surface Plates provide a precision reference for spotting, tool making, inspection of parts, checking accuracy of other surfaces and for many types of gauging and marking out operations:

• Made generally as per IS-2285-2003
• Made from good quality close grained high duty Cast Iron ,Castings conforming to Grade FG-220 of IS-210, duly stress relieved
• Small Surface Plates up to 630 x 630 mm provided with Mild .Steel handles for lifting, larger Surface Plates without handles but provided with cored holes in periphery for lifting mechanically.
• Top surface offered with hand-scrapped finish.
• Rexine cover provided for top working surface and edges.

We are leading manufacturer of Cast Iron Swivel Angle Plates. Job can be quickly and correctly set at any Angle with the adjustable angle Plates. They are graduated for setting 0-90º & can be easily adjusted manually and locked in adjusted position by means of two locking nuts. For setting purpose, a degree scale, reading minimum one degree, is graduated on the boss itself. This ensures better setting accuracy. Swivelling face is provided with T-slots Machined from solid. Other face is provided with cored elongated slots for clamping the Angle Plate on the Machine Table.

Features:

• Made from close grained Cast Iron Casting conforming to Grade FG-220 of IS-210. Casting duly stress relieved.
• Working faces flat within 0.010 mm per 300 mm and square and parallel within ± 0.04 mm per 300 mm in two
• extreme positions.
• Edges parallel and square within 0.05 mm per 300 mm
• T-slots parallel to the edges within 0.05 mm per 300 mm.

Microflat V-Blocks are widely used in Workshops, Tool Rooms & Standard Rooms for variety of application in Tooling and Inspection purposes such as marking accurate Centers, checking Concentricity, Parallelism, etc.
