|Great Rigidity, infallible Precision|
High efficiency surface grinders are among PROFIMACH’s impressive range of
Machine Tools. Like all of PROFIMACH’s products, every single one of their
surface grinders are intricately designed to totally accommodate the infinite
demands that high mix production places on businesses of any size, no matter
how big or small. Featuring high rigidity with PRO/E analytical physics design
and endurable mechanical stability, the PROFIMACH surface grinder range is
certainly your best companion for high precision surface grinding jobs.|
|PGS – Surface Grinders Range|
These high precision surface grinders have been specially
developed and improved in recent years. The optimum
span of double V crossfeed guideways is designed based
on bending moment, kinematics and supporting force. All
essential castings are made of high grade of cast iron that
is stress relieved through annealing to eliminate internal
stress. With the greatest stiffness and stability of the castings, these machines
are suitable for precision surface grinding.
These grinders are offered with onefull-year
limited warranty for mechanical and electrical parts.|
|All machines are traditional in design with easy access for complete, accurate and efficient control. All models are suitable for toolroom and production work. The longitudinal table movement is hydraulically driven and the cross traverse and wheel head feeds are electrically driven, all with infinitely variable speed control.|
• Compact structure gives the machine small footprint
• Meehanite type, cast iron base
• Fully ribbed column to ensure the highest rigidity
• Hydraulic transmission on longitudinal; manual / automatic vertical feed (see model)
• Easy operation
• Digitally controlled, automatic vertical feed with servo motor (AHD model)
• Rapid feed to height of work-piece, adjustable to finishing and sparking, automatic lift at program end (AHD model only)
• Electromagnetic chuck for work holding
MACHINE STRUCTURE |
The highly advanced PSG series of precision surface grinding machines are a result of the ongoing and extensive research and development program at PROFIMACH. In addition to improved accuracy, quality, and machine life, the overall design of the machine incorporates ergonomics; all operating hand wheels, levers, stroke setting devices and the pendant control panel are arranged to allow ease of operation, which increases working efficiency.
The Profimach PGS Automatic Surface Grinding Machines are produced with highly rigid cast iron body and precision machined and grinded, ensuring maximum rigidity. They are designed to operate with low vibration and high accuracy.
Machine Base has extra wide V guideways with great span inbetween and high frequency hardened surfaces, exhibiting outstanding stability during grinding operation. In combination with fine hand scraped slideways, the axis movement guarantees high accuracy and maximum durability. Machine-base slideways are laminated with Turcite-B and precisely hand-scraped, lowfriction slide ways incorporated with an automatic intermittent lubrication system to ensure high accuracy and longer life of slide ways.
Longitudinal table movement
The longitudinal table movement is hydraulically driven. Well designed and carefully assembled Hydraulic unit makes the table move smoothly even at full load. The table guideway system is composed of hardened and ground steel guideways with precision needle roller bearings to provide excellent longevity and low friction, and also to provide precise linear movement without deviation, even during rapid traverse movement.
High Precision Spindle type
The spindle is supported by superprecision angular-contact ball bearing. The bearings have been accurately measured, selected and preloaded and then assembled to ensure superior water resistance, longevity grinding accuracy and surface finish. It's assembled in a temperature controlled room to ensure better grinding accuracy and surface finish. The labyrinth seal type structure is designed to offer superior water resistance, increasing the life of the spindle bearings. The spindle is permanently lubricated and requires no maintenance. Spindle motor, spindle shaft, and couplings are precisely balanced to ensure accuracy and superb surface finish.
Spindle Elevating Guideway System
The wheel head and column system is composed of hardened and ground inserted steel guideways and precision roller bearings. The wheel head and column guideways are preloaded providing zero clearance for precise straight line movement. The low friction wheel head guideway system enables accurate feeds even at micron level increments.
Lubrication of all slide ways is done by means of an electronically controlled centralized one-shot lubrication pump unit through metering valves to all the various lubrication points. The lubrication system provides lube oil to saddle, column ways, crossfeed and elevating leadscrews. This system minimizes the wear due to negligent operation, ensuring the machine accuracy and extending the life of machine.
Independent hydraulic station with cooling unit, keeps the oil stable with small temperature rise and provides enough power for precision grinding.
Well-designed control panel with two-way rotating structure, helps the operator getting the suitable position very easy, improving work efficiency.
The electrical system has been designed according to the CE standard. Safe and reliable electrical control, safety interlocking protection system, all the electro parts are from top producers like SIEMENS (Germany), OMRON (Japan), SCHNEIDER (France). For AHD model, the spindle elevating motor adopt servo motor and is controlled by Siemens PLC.
Depending on the workpiece material, the work is generally held by the use of a magnetic chuck. The PROFIMACH PGS surface grinding machines are equipped with a strong magnetic chuck with a unique coil design and leakproof seal for increasing chuck’s life.
