CNC centerless grinder

The main body and main components are made of high-grade cast iron FC-30, which is processed by artificial stewing and natural aging to ensure that the materials of the main body and components are stable and wear-resistant.

Each component is processed using YASDA, MITSUI SEIKI, TOSHIBA, OKUMA, OKAMOTO and other equipment for one-time clamping processing. The precision size can reach the micron level, ensuring high precision of the basic components of the equipment.

The driving motor of the adjusting wheel spindle adopts a servo motor, and the rotation speed can be set arbitrarily from 10 to 250 rpm. It is convenient to adjust to the maximum rotation speed during grinding. When the outer diameter of the adjusting wheel changes, the same linear speed can still be maintained to grind the product.

The servo motor is cleverly designed and installed on the adjusting wheel box and directly driven by a timing belt. It can rotate the angle synchronously with the adjusting wheel box during grinding.

Make sure the two pulleys are always parallel.

It overcomes many adverse effects caused by the included angle when the old centerless grinder is driven by a chain, and avoids frequent replacement of the chain and zipper spring.

The dressing seat is made of special alloy cast iron and undergoes multiple treatments including tempering and vibration to ensure stability and wear resistance.

The dressing slide is designed with a dovetail shape and a widened track surface. It is precision manual scraping after one-time molding and grinding processing. It can be used with hydraulic reciprocating trimming or servo motor for molding trimming.

The upper slide rail is designed with a dove-shaped groove structure and has a plus or minus 5-degree rotation function, making adjustment simple and quick.

The lower slide plate adopts double V-shaped slide rails and double wedge-shaped auxiliary rails. The structure is stable and can avoid the intrusion of cutting fluid, making it easy to maintain.

Both the upper and lower slides can be equipped with manual and automatic fine-tuning feeds, with an accuracy of up to 0.001MM.

The high-precision hydrostatic spindle is designed and developed for the workstation of Academician Fu Xincheng.

The working pressure of the static pressure bearing is 25 MPa, and the main shaft is suspended in the static pressure bearing oil film, achieving high precision, high rigidity, high speed and low friction.

The use of high-pressure oil film to carry heavy loads and heavy cutting can effectively reduce spindle wear and maintain spindle operation accuracy.

The static pressure rail is a product designed and developed for Academician Fu Xincheng’s workstation and has successfully applied for invention.

The track is designed as a fully enclosed hydrostatic suspension track with small hole throttling.

The entire track is suspended in a high-pressure oil film when working, and the friction coefficient is less than 0.001.

There is no contact between the working surfaces when the track is running, and there is no wear and long service life.

The static pressure oil film has strong rigidity and its thickness is almost not affected by speed. It will not crawl even at extremely low speeds and can achieve 0.0001MM feed setting.

The main shaft of the B-type adjusting wheel rolling bearing is designed with a double support structure, using FAG double row roller bearings and angular contact bearings.

Even during low operating speeds and heavy cutting, the spindle can rotate with ultra-high precision and maintain rigidity.

Ensure the true roundness and cylindricity of the ground products.

A CNC control system is selected, using precision ball screws and servo motors for numerical control.

It can realize the automatic feeding of the upper and lower rails according to the grinding process, and realize automatic dressing and automatic compensation of various shapes of the grinding wheel and adjusting wheel.

It greatly improves the centerless grinder's processing ability for complex-shaped workpieces and reduces the difficulty of manual operation.

A variety of automatic loading and unloading and automatic detection solutions are available to choose from, realizing fully automatic processing and production of high-precision parts.

Version 2.0 of the centerless grinder grinding software professionally developed by Fuxincheng is equipped with a CNC control system and provides a conversational operation interface. All settings can be completed with simple data input, making the operation simple and convenient.

The CNC dressing device provides a precise and fast dressing solution for processing multi-step and complex-shaped workpieces.

Both the grinding wheel and the adjusting wheel can be trimmed into various shapes required according to the requirements of the grinding process.

Diamond pens, butterfly rollers, and shaping rollers can be used as trimming tools.
