Internal Grinders
FORTUNE PACIFIC has a full line of small diameter Internal Cylindrical Grinding Machines, also knows as ID grinders. From multi work-head/multi spindle machines, to hydrostatic ways and linear motors. FORTUNE PACIFIC has the ability to hold ultra tight tolerances on bores, angles, and faces. Our ID grinders are very popular for fuel injector grinding in the automotive industry.

Features
Feed and dressing movements are controlled by means of two independent driving systems. Size-metric grinding is adopted. Feed movement can be carried out both manually and hydraulically.
The machine is equipped with jumping mechanism, it is unnecessary to reset the tool after returning grinding wheel for measurement or dressing.
The machine is equipped with a hydraulic switch to ensure safety during loading and unloading workpiece.

IG200 Internal Cylindrical Grinder, often shortened to grinder, is any of various power tools or machine tools used for grinding, which is a type of machining using an abrasive wheel as the cutting tool. Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation.

Grinding is used to finish workpieces that must show high surface quality (e.g., low surface roughness) and high accuracy of shape and dimension. As the accuracy in dimensions in grinding is of the order of 0.000025 mm, in most applications it tends to be a finishing operation and removes comparatively little metal, about 0.25 to 0.50 mm depth. However, there are some roughing applications in which grinding removes high volumes of metal quite rapidly. Thus, grinding is a diverse field.

Overview
The grinding machine consists of a bed with a fixture to guide and hold the work piece, and a power-driven grinding wheel spinning at the required speed. The speed is determined by the wheel’s diameter and manufacturer’s rating. The grinding head can travel across a fixed work piece, or the work piece can be moved while the grind head stays in a fixed position.

Fine control of the grinding head or table position is possible using a vernier calibrated hand wheel, or using the features of numerical controls.

Grinding machines remove material from the work piece by abrasion, which can generate substantial amounts of heat. To cool the work piece so that it does not overheat and go outside its tolerance, grinding machines incorporate a coolant. The coolant also benefits the machinist as the heat generated may cause burns. In high-precision grinding machines (most cylindrical and surface grinders), the final grinding stages are usually set up so that they remove about 200 nm (less than 1/10000 in) per pass - this generates so little heat that even with no coolant, the temperature rise is negligible.
