Diamond Wheel Dressing Machine /CBN/Grinding Wheel(manual type)

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.

More accurate wheel shape requires toprecisely process a workpiece.

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.

Features of DFM-series

The each parts of the machine posses high stiffness. Accordingly,diamond or CBN grinding wheels are formed at high accuracy.
The top of the work is an exchangeble type and is provided with a centering mechanism. For that reason, it is easy to mach the work with the flanges of every company.
Oscillation of the grinding wheel spindle with a crank mechanism has a silent motion.
This machine is combined by a compact design. For that,it is easy to work and not necessary for it to get a big space.
It can combine many options economically suiting for various uses.(Auto in-feed, Swiveling)

Formed work samples

Auto in-feed, Swiveling

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.

Increase of durability

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.

Options

Simple CCD camera (included monitor)

Allows precise monitoring of the work forming condition.

Wheel spindle angular offset device

Allows forming of both sides of as small diameter work by one chucking without turning it over.

Work spindle arbors

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.
