The Mechanism and Kinematics of a Pantograph Milling Machine. The pantograph mechanism is used to design and fabricate a milling machine which could traverse on any contour provided that stylus is moved along the same on any already existing object.
World wide first CNC Tool Grinding Machine built on granite. Precision in micro range by granite construction - making tools in diameter range of 0.2 to 10 mm. Grinding at the accuracy of measuring machines: due to the portal built entirely of granite.
• grinding –mostly for gears after heat treatment - form grinding - involute - generating grinding • lapping • teeth rounding –creating a shape of tooth (in the direction parallely to the axis of rotation) to make changing gears easier
Discontinuous profile gear grinding is mostly utilised for small batch series and prototype manufacturing. Dressable ceramic wheels as well as non-dressable CBN tools can be used for this grinding process. KAPP NILES provides a wide spectrum of machine models suited to the processes of profile and generating grinding.

Kinematic analysis and feedrate optimization play an important role in efficient machining with NC machine tools. After analyzing the basic kinematic relation of the six-axis NC abrasive belt grinding machine tool, coordinate systems are established to calculate the generalized kinematics model.
A grinding machine, often shortened to grinder, is one of power tools or machine tools used for grinding, it 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.
This paper shows that in a machine where all the axes can move simultaneously only two rotations and one translation are required to grind drill points. The design methodology employed in this paper uses modern matrix kinematic methods. The kinematic equations developed are simple enough to be solved iteratively on a desktop computer.
The U-axis has dual functionality: it can be used as a positioning axis or a free-turning spindle (used when cylindrical grinding). The TTB kinematic allows the wheels to grind above or below the tool. The thermal stability of the machine components is guaranteed by the use of temperature controlled fluids.
Surface grinding is used to produce a smooth finish on flat surfaces. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth.
Oct 21, 2009· Introduction: Milling is the cutting operation that removes metal by feeding the work against a rotating, cutter having single or multiple cutting edges. Flat or curved surfaces of many shapes can be machined by milling with good finish and accuracy. A milling machine may also be used for drilling, slotting, making a circular profile and gear cutting by having suitable attachments.
