Luthra Surface & Angle Plates

Surface Plates
We manufacture and supply a wide range of surface plates, which are used in various industries for tool making, inspection, spotting, gauging etc. Our range of surface plates are specifically designed to provide an accurate reference plane for work inspection and also for work layout. These surface plates are strictly in compliance with international quality standards and can also be customized as per the specifications laid down by our clients. Our range of surface plates includes cast iron surface plates, precision cast iron surface plates and precision granite surface plates.
Granite Surface Plates

Granite Surface Plates

Granite surface plates are manufactured using natural black granite tone, quarried from earth in its natural form. These precision granite surface plates are precision lapped to high standards of flatness to achieve accuracy and are used as bases for mounting sophisticated mechanical, electronic and optical gauging systems. Our quality inspectors and engineers put a strict vigilance at all the stages of ensure high quality plates. Further, the final inspection is carried out by a high precision computerized electronic level made by Wyler Of Switzerland. Our range of precision granite surface plates are utilized in Precision tool rooms, Engineering industries and Research laboratories.

Cast Iron Surface Plates

Cast Iron Surface Plates

We offer a qualitative range of precision cast iron surface plates. These cast iron surface plates provide an accurate reference plane for precision gauging, inspection and tooling setup. We make use of good quality closed grain cast iron that is as per the IS 210:1993 confirming to Grade FG-220.The meticulous manufacturing processes that are carried out at our premise makes these cast iron plates apt for machine shops, quality control and standard rooms. Our precision cast iron surface plates are utilized in the applications, where strict accuracy required hence, these plates are appropriate for high precision work and are ideal for blue matching.

Slotted Angle Plate

Slotted Angle Plate

We manufacture and supply a wide range of slotted angle plates, which are largely sed
in various industries for clamping and holding work in vertical position. These slotted angle plates are also used as a vertical reference for inspection and tooling purposes such as shaping, planning, milling, grinding, drilling etc. All 6 working faces of our angle plates are hand scrapped to desired accuracy and are square/right angle to each other.
Fabricated using high quality closed grain cast iron of Grade FG-220, these angle plates comply with IS 2554:1971 standards.

Plain Angle Plate
Plain Angle Plate

a wide range of plain angle plates, which are largely used in various industries for clamping and holding work in vertical position. These plain angle plates are also used as a vertical reference for inspection and tooling purposes such as shaping, planning, illing, grinding, drilling etc. All six working faces of our plain angle plates are hand scrapped to
desired accuracy and are square and right angle to each other. Fabricated using high quality closed grain cast iron of Grade FG-220, these angle plates comply with IS 2554:1971 standards.

Box Angle Plates
Box Angle Plates

We specialize in offering qualitative box angle plates. These are basically used for shaping and milling, wherein, job can be fixed on one of its faces and are rotated in 5 positions without the need of repositioning or disturbing accuracy. Our range of box angle plates is used in diverse engineering industries where all the parameters such as
squareness, flatness and parallelism are required in a single instrument. These parameters are true to each other for effective functioningof the plates.
