Diamond wheel from dressing and truing machines are full-dressforming machines that perform high-accuracy from dressing and truing of diamond wheels as well as CBN wheels with outstanding efficiency.
DFM410 Mechanism element
Even if you have a high precision CNC grinding machine, an precise shape is not formed by a wheel that is distorted and wore the tip R.
DFM series can possible to adjust a tip R shape of wheel by easy action, and perform high accuracy processing.
Processing a work with precise can not by such a distorted wheel.
To achieve a high precision shape by correcting a shape of tip with high accuracy.

This ratchet feed mechanism allows intermittent automatic infeed within the range from 0.0025mm (minimum) to 0.03mm (maximum), with the maximum auto-infeed amount being 50mm. The performance of this device is significant when machining requires fine infeed or takes long time.(optionally for DFM210)
Automatic swiveling is possible. Swiveling angle is set by the stoppers which allow precise setting while eliminating errors due to repetition of swiveling return motions. It is possible to process such as grinding tools exactly an arc(corner radii).(DFM410R)
The swivel drive adopts am airhydro-mechanism to secure smooth rotation of the wheelhead and to minimize the thermal deformation at the same times.
It is true that the most cumbersome enemy against maintenance of accuracy and performance of a wheel forming machine are abrasive grains produced through forming operation.
Once abrasive grains that contain diamond or CBN particles enter the machine parts, they will invade and erode the movable parts andoptical system soon like a virus. We have given the utmost care to dustproof measures and coolant penetration for the DFM-series, and still continue to provide further improvements.
For the most important wheelhead swivel mechanism, a combined system of labyrinth and air purge is adopted for dustproof and waterproof measures. The swivel base is internally pressurized with 99.99% or more moistureless air to provide an air curtain to prevent external coolant splash and abrasive grains from entering the inside.
The effectivity of this system greatly contributes for improvement of the machine durability.
Allows precise monitoring of the work forming condition.
Allows forming of both sides of as small diameter work by one chucking without turning it over.
By making use of high-prection replacable arbors that fit various wheel flanges of different manufactures'grinders, the work spindle nose can be adapted to many types of wheel flanges at low cost.
