CNC centerless grinder

HC-5020/30CNC-XCNC centerless grinderFeatures:

Body and main components

The body and main components are made of high-grade cast ironFC-30It is cast and processed by artificial stewing and natural aging to ensure that the body and component materials are stable and wear-resistant.Each component is processed usingYASDA、MITSUI SEIKI、TOSHIBA 、OKUMA 、OKAMOTOThe equipment is clamped and processed at one time, and the precision dimensions can reach the micron level, ensuring high precision of the basic components of the equipment.

Adjustment wheel drive system

The driving motor of the adjusting wheel spindle adopts servo motor.Speed10~250rpmIt can be set arbitrarily and can be easily adjusted to the maximum speed during grinding. When the outer diameter of the adjustment wheel changes, the same linear speed can be maintained to grind out 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.

   Dressing device

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.

sliding mechanism

The upper slide rail is designed with a dove-shaped groove structure and has positive and negative5The function of degree rotation makes adjustment simple and quick. The lower sliding plate adopts doubleVType slide rail and double wedge-shaped auxiliary rail, 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 of the feed, with an accuracy of up to0.001MM .

Hydrostatic spindle

The high-precision hydrostatic spindle is a product designed and developed for Academician Fu Xincheng’s workstation. 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.

Hydrostatic guide

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.

BType adjusting wheel rolling bearing spindle

BThe main shaft of the adjusting wheel rolling bearing is designed as a double support structure.FAGDouble row roller bearings and angular contact bearings. Even when the working speed is low and heavy cutting, It can also maintain the rigidity achieved by ultra-high-precision rotation of the spindle. Ensure the true roundness and cylindricity of the ground products.

CNC system and software

CNC centerless grinderSelectCNCThe control system uses 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.

Centerless grinder grinding software professionally developed by Fuxincheng2.0version, matchCNCThe control system provides a conversational operation interface. All settings can be completed with simple data input, making the operation simple and convenient.

CNCDressing device

CNCThe dressing device provides an accurate 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.
