・ Truing can be done about 5 times faster than conventional products.

・ In the horizontal axis type, the dressing / truing condition changes due to the speed change due to the outer diameter decrease of the dressing toilet, but the condition does not change in the vertical shaft type.

※ To use this equipment, "Toy axle continuously variable transmission" is a required option.

～Epoch making tool appeared after the sign bar chuck～

Vertical rotary dresser

Example workpiece

Feature

・ Innovative function expansion tool born from the mold manufacturing site. Rotating machining which is impossible in the past can be easily realized with high precision.

・ Semi-convex, medium concave machining is also possible by using the bar bar chuck. The forming grinding machine / surface grinding machine will be able to move in the same way as a small rotary grinding machine in 5 minutes.

～ Grinding quality changes with truing / dressing ～

DIA tool

Feature

・ Innovative function expansion tool born from the mold manufacturing site. Rotating machining which is impossible in the past can be easily realized with high precision.

・ Semi-convex, medium concave machining is also possible by using the bar bar chuck. The forming grinding machine / surface grinding machine will be able to move in the same way as a small rotary grinding machine in 5 minutes.

※ Dressing (dressing)

To crush the abrasive grains on the clogged face of the sprout to make a cutting edge.

※ Truing (reforming)

Make the shape of the palm concentric with the outer diameter of the brush and the center of the shaft.

～ Do not you have trouble with "warpage" ～

Feature

・Easy setup

Instead of spacers, shims, bean jacks etc. used in conventional warpage work, it is possible to apply the magnetic force of the magnet chuck and hold the invisible surface of the material as it is.

・Suitable for all kinds of materials

Magnetic force is used only for holding jigs and is not transmitted to the material, so it is ideal for not only magnetic material but also non-magnetic aluminum, stainless steel, resin etc grinding.

・ Excellent planar accuracy

Grinding while retaining the incorrect surface of the material as it is, and also grinding while absorbing the strain during grinding ensures micron precision with a single grinding even for materials with large warp and twist.

～ High grinding power ・ Long life force ・ Low heat generation ～

Features What is CUBITRON TM II Wheel?

Ceramics with precision molded abrasive using 3M company's core technology "micro replication technology (high definition surface technology)". We propose efficiency ratio grinding by collaboration with rigid grinding machine of Okamoto Machine Tool Machinery Works.

Feature

・ Compared to the conventional case, the penetration input to the workpiece is high, and generation of grinding heat is suppressed. This enables deeper cuts and high-speed feed.

・ The dress characteristic which is said to be weak point of ceramic abrasive grain also improved. Regenerate the edge from the flat surface of the triangle to recover sharpness, dresser wear is also reduced.

・ In collaboration with Okamoto Machine Tool Machinery Works, there are examples of surface grinding machine, cylindrical grinding machine, internal grinding machine, compound cylindrical grinding machine, rotary grinding machine, gate type grinding machine, gear grinding machine. For details, please contact your sales representative.

※Cubitron TM II is a product of 3M company.

～ Change bubble, propose new common sense of grinding ～

Structure of GRIND-BIX

Feature

・ Coanda effect improves coolant / grinding fluid permeability

The swirling flow jet derived from the internal structure of GRIND - BIX ensured the grinding coolant liquid to spread to the tip of the abrasive grain by the Coanda effect, greatly improving the cooling capacity. As a result, cutting depth of 5 to 10 times is possible, contributing to reduction of machining time and improvement of accuracy.

(The effect varies depending on the workpiece, workpiece, and condition.)

・ Prevention of clogging of jaws by cavitation phenomenon

Secondary vibration when fine bubbles (bubbles less than several hundred nanometers in diameter) can be blown are constantly washed inside the pores, preventing clogging of the pins. As a result, the cutting edge is maintained, continuous grinding of several tens of microns is also possible without requiring sharpening even with # 2000 high mesh.

～ Incredible grinding efficiency. Reduce cycle time from general grinding. ～

Feature

・Prevent clogging of the grinding wheel due to cavitation.

・Coanda effect improves coolant penetration.

・TWINBIX's cooling effect is 30% higher than conventional BIX.

～ Mechanism for achieving high efficiency ～

Cylindrical grinding can be performed with a surface grinder.

・Centerless cylindrical grinding can be performed with a surface grinder.

・It is used for machining ejector pins of molds, etc.

・ By developing the Ultra Screw which applies the screw rotating force only to one direction of pressing, the work can not be scratched and lifting at the time of work tightening can be prevented, so accurate chucking is possible.

In addition, by mounting the resin work guard on the Ultra screw, the soft material will not be scratched.

・ It can be used as a reference block only on the main body because of the full circumference high precision grinding finish.

・ There is an integral type and a division type, but the UVH - 40 of the division type and integral type has a structure that can be corrected and chucking is possible arbitrarily.

・ It can be used as a reference block only on the main body because of the full circumference high precision grinding finish.

・ Excellent characteristics not only in accuracy but also in abrasion resistance and rust resistance.

・ Gauge block is used for angle setting.

・ It is a mechanism to clamp the gauge block between the stage and the roller, and stable accuracy can always be maintained.
