DUPLEX SURFACE GRINDERS

VERTICAL DUPLEX SURFACE GRINDERS

INTRODUCTION

Duplex Surface Grinder is specially designed for machining workpiecesof steel, cast, iron, non ferrous metals and light alloys.The grinder is remarkable for very simple servicing. All controls are accomodated on a desk in the front part of the machine.

"Ajit" Duplex Surface Grinders are specially designed for surface grinding of opposite and parallel surfaces to close limits of accuracy. The machine is most suitable for size paralleism, uniformity and high rates of production. The grinding of two opposite surfaces in one operation is accomplished by passing the component between the faces of parallel abrasive discs.

OUT STANDING FEATURES

Production is fully continuous.
Output is higher due to reduction in each handling time and setting up time.
Stable dimensions can be maintained in each lot of workpieces.
Less skill is required to operate the machine.
The clamping of the components before proceeding with the second face is fully eliminated.

Three fundamental methods of work-feed are used as shown in figures below
ROTRAY FEED Parts are fed in between the abrasive discs by a continuous rotating workcarrier.	THROUGH FEED Parts are fed by power between the abrasive discs in a stright path.
OSCILLATING FEED Parts are cam clamped and plunged manually between the abrasive discs Reciprocating power feed can also provided.
DUPLEX GRINDER Duplex Grinder for Piston Tings, Cross Bearing, Piston Pins, Hand Tools, Valve Seat, etc. as per customer's specifications are also manufactured.
