Surface grinding is used to produce a smooth finish on flat surfaces. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth.
Process
Surface grinding is the most common of the grinding operations. It is a finishing process that uses a rotating abrasive wheel to smooth the flat surface of metallic or nonmetallic materials to give them a more refined look by removing the oxide layer and impurities on work piece surfaces. This will also attain a desired surface for a functional
purpose.
SG618 SG818 Manual Surface Grinding Machine is composed of an abrasive wheel, a workholding device known as a chuck, and a reciprocating or rotary table. The chuck holds the material in place while it is being worked on. It can do this one of two ways: ferromagnetic pieces are held in place by a magnetic chuck, while non-ferromagnetic and nonmetallic pieces are held in place by vacuum or mechanical means. A machine vise (made from ferromagnetic steel or cast iron) placed on the magnetic chuck can be used to hold non-ferromagnetic workpieces if only a magnetic chuck is available.
Factors to consider in surface grinding are the material of the grinding wheel and the material of the piece being worked on.
Typical workpiece materials include cast iron and mild steel. These two materials don't tend to clog the grinding wheel while being processed. Other materials are aluminum, stainless steel, brass and some plastics. When grinding at high temperatures, the material tends to become weakened and is more inclined to corrode. This can also result in a loss of magnetism in materials where this is applicable.
The grinding wheel is not limited to a cylindrical shape and can have a myriad of options that are useful in transferring different geometries to the object being worked on. Straight wheels can be dressed by the operator to produce custom geometries. When surface grinding an object, one must keep in mind that the shape of the wheel will be transferred to the material of the object like a reverse image.

Surface Grinding machines
A Surface Grinding machine/Surface grinder consists of an abrasive wheel, a chuck (a workpiece holding device), and a rotary table. The chuck is used to hold the material in place while the wheel and object are rotated to produce a smooth finish.
Surface Grinding machine/Surface grinder, which has a head that is lowered to a work piece, which is moved back and forth under the grinding wheel on a table that typically has a controllable permanent magnet (magnetic chuck) for use with magnetic stock (especially ferrous stock) but can have a vacuum chuck or other fixture means. The most common surface grinders have a grinding wheel rotating on a horizontal axis cutting around the circumference of the grinding wheel. Rotary surface grinders, commonly known as "Blanchard" style grinders, have a grinding head which rotates the grinding wheel on a vertical axis cutting on the end face of the grinding wheel, while a table rotates the work piece in the opposite direction underneath. This type of machine removes large amounts of material and grinds flat surfaces with noted spiral grind marks. It can also be used to make and sharpen metal stamping die sets, flat shear blades, fixture bases or any flat and parallel surfaces. FORTUNE PACIFIC Surface Grinding machine/Surface grinders can be manually operated or have CNC controls.
A grinding machine, often shortened to grinder, is any of various power tools or machine tools used for grinding, which is a type of machining using an abrasive wheel as the cutting tool. Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation.
Grinding is used to finish workpieces that must show high surface quality (e.g., low surface roughness) and high accuracy of shape and dimension. As the accuracy in dimensions in grinding is of the order of 0.000025 mm, in most applications it tends to be a finishing operation and removes comparatively little metal, about 0.25 to 0.50 mm depth. However, there are some roughing applications in which grinding removes high volumes of metal quite rapidly. Thus, grinding is a diverse field.
Overview of grinding machine
The grinding machine consists of a bed with a fixture to guide and hold the work piece, and a power-driven grinding wheel spinning at the required speed. The speed is determined by the wheel’s diameter and manufacturer’s rating. The grinding head can travel across a fixed work piece, or the work piece can be moved while the grind head stays in a fixed position.
Fine control of the grinding head or table position is possible using a vernier calibrated hand wheel, or using the features of numerical controls.
Grinding machines remove material from the work piece by abrasion, which can generate substantial amounts of heat. To cool the work piece so that it does not overheat and go outside its tolerance, grinding machines incorporate a coolant. The coolant also benefits the machinist as the heat generated may cause burns. In high-precision grinding machines (most cylindrical and surface grinders), the final grinding stages are usually set up so that they remove about 200 nm (less than 1/10000 in) per pass - this generates so little heat that even with no coolant, the temperature rise is negligible.

A kezelők értékelik az állandó csiszolási pontosságot, a finom előtolásszabályozást optimális anyagleforrási sebességekért, valamint a tartós kivitelezést hosszú élettartamért. A kézi működtetés közvetlen visszajelzést biztosít bonyolult munkadarabokhoz, első választásként téve őket finom síkcsiszolásra, szerszámformák karbantartására és befogólemezek megmunkálására, ahol CNC automatizálás nem szükséges. Οι χειροκίνητες μηχανές λείανσης επιφανειών SG618 και SG818 είναι ανθεκτικές μηχανές, απαραίτητα εργαλεία για ακριβή επίπεδη λείανση. Γνωστές και ως μηχανές λείανσης εργαλείων, εξοπλισμός συντήρηης καλουπιών ή επιτραπέζιες μηχανές λείανσης επιφανειών, χρησιμοποιούν περιστρεφόμενη λιάνθη για αφαίρεση υλικού, επιτυγχάνοντας εξαιρετική ομαλότητα επιφάνειας (Ra) και στενές ανοχές σε επίπεδο μικρομέτρων. Η βασική δομή τους περιλαμβάνει βαρύ χυτοσιδηρή βάση για λειτουργία χωρίς κραδασμούς, χειροκίνητο τραπέζι εγκάρσιας τροφοδοσίας με διαμήκη κίνηση (μοχλός ή υδραυλική επιλογή), και κατακόρυφα ρυθμιζόμενη κεφαλή λιάνθης. Βασικά εξαρτήματα: κινητήρας ατράκτου, ακριβείς οδηγοί, μηχανισμός τροφοδοσίας τραπεζιού, σύστημα ψύξης υγρού κοπής και προαιρετική συσκευή ευθυγράμμισης λιάνθης. Χρησιμοποιούνται ευρέως στην κατασκευή καλουπιών, συνεργεία εργαλείων, ακριβή μηχανοποίηση και μικρές σειρές παραγωγής. Αυτές οι χειροκίνητες μηχανές επίπεδης λείανσης προσφέρουν πλεονεκτήματα: υψηλή ακαμψία για ακριβή αποτελέσματα, φιλικό χειρισμό ιδανικό για ειδικευμένους χειριστές, εξαιρετική αξιοπιστία με ελάχιστη συντήρηση και ευελιξία για λείανση διαφόρων μετάλλων. Οι χειριστές εκτιμούν τη σταθερή ακρίβεια λείανσης, τον λεπτό έλεγχο τροφοδοσίας για βέλτιστο ρυθμό αφαίρεσης υλικού και την ανθεκτική κατασκευή που εγγυάται μεγάλη διάρκεια ζωής. Η χειροκίνητη λειτουργία παρέχει άμεση ανατροφοδότηση κρίσιμη για πολύπλοκα κομμάτια, καθιστώντας τις κορυφαία επιλογή για λεπτή επίπεδη λείανση, συντήρηση καλουπιών και επεξεργασία πλακών στερέωσης όπου δεν απαιτείται CNC αυτοματισμός. Brusky na plocho SG618 a SG818 jsou robustní ruční brusky, nezbytné stroje v dílně pro přesné rovinné broušení. Známé také jako brusky na nástroje, zařízení pro údržbu forem nebo stolní brusky na plocho, používají rotující brusný kotouč k odstraňování materiálu, dosahují výjimečné drsnosti povrchu (Ra) a těsných tolerancí na mikrony. Jejich základní konstrukce zahrnuje těžkou litinovou základnu pro chod bez vibrací, ručně ovládaný příčný stůl s podélným posuvem (ruční kolo nebo hydraulická varianta) a svisle nastavitelnou brusnou hlavu. Klíčové součásti: vřetenový motor, přesné vodící lišty, mechanismus posuvu stolu, chladicí systém a volitelný zařízení na přebrušování kotouče. Široce používané ve výrobě forem, nástrojárnách, přesném obrábění a malosériové výrobě, tyto ruční rovinné brusky nabízejí výhody: vysoká tuhost pro přesné výsledky, intuitivní ruční ovládání ideální pro operátory, výjimečná spolehlivost s minimální údržbou a univerzálnost pro broušení různých kovů. Operátoři oceňují stálou přesnost broušení, jemné nastavení posuvu pro optimální rychlost odběru a odolnou konstrukci zajišťující dlouhou životnost. Ruční ovládání poskytuje přímou zpětnou vazbu klíčovou pro složité obrobky, což z nich dělá první volbu pro jemné rovinné broušení, údržbu forem a opracování upínacích desek tam, kde není vyžadována CNC automatizace.
