Puts forward new requirements for tool grinding machine tool development
Most ordinary HSS cutting tools and the common welding carbide cutting tools have been unable to meet the requirements of modern processing technology, and gradually be precision overall carbide cutting tools and all kinds of nc indexable tool, precision carbide cutting tools with high speed steel cutter, the common welding tool in the process of grinding process on the requirements for the performance of the machine tool has the very big difference, and the launch of high-precision CNC multi-axis linkage tool grinder and the development of machine tool grinding function and performance meet the carbide cutting tools large quantities of many kinds of requirements of high precision grinding process, nc tool grinding machine of all brands are generally possess powerful CNC software simulation to edit and high precision grinding machine control system, processing the products according to user requirements, different brands of tool grinding machine has its unique advantage: if some suitable for small and medium-sized specifications of large quantities of precision machining tool, some suitable for high precision, small size some suitable for large diameter high efficiency high precision machining, some suitable for processing of non-standard cutting tools, some machine efficiency fitted her for more specifications small batch processing, some suitable for super long diameter cutter blade processing, etc.
Cutting tool manufacturing with tool grinder is mainly divided into two categories, one is imported five axis, six axis linkage CNC tool grinding machine, the main brands are ROLLOMATIC, three berger, EWAG, AGTHON, WALTER, WENDT, Shute, Isaac, ANCA, dirk, TTB and other international brand;One kind is simple manual multifunctional special grinding machine at home and abroad, the main brands are Beijing demint, beiping machine tool, nanjing is higher.
CNC tool grinding machine generally adopts world advanced electric control software system, data precision guide rail and the screw motor system, positioning system and other advanced precision grating and servo motor feedback module design, therefore, the CNC tool grinding machine has high precision grinding motion control technology, CNC tool grinding machine is equipped with a powerful 3 d machining simulation software, the user can according to your own cutting tool structure and parameters design requirements online simulate machining tool shape you want.Manual for the characteristics of the tool grinding machine is simple in structure, convenient in operation, mainly applied to the production of non-standard cutting tools and manual cutting tool grinding.
Grinding mainly has two ways: one is the dimension accuracy is not high, the blade shape simple ordinary cutting tool, the user manually by ordinary tool grinding machine grinding, edge of this way of grinding features a high requirement for grinding the teacher, must have a certain tool, after grinding tool in general can only be used for rough machining;Is a complicated shape and high dimension precision of whole cutting tool, the user is usually used to entrust manufacturer of tools or a local professional grinding tool factory to grinding machining, the grinding tool is the feature of the grinding process is through the software program editing and probe precision positioning, fully in accordance with the original tool design parameters and the geometrical angles grinding, finish grinding tool performance and service life can reach more than 90% of the new knife.The user can choose according to the requirement of different above two ways tool grinding processing, can save the use of the cemented carbide raw materials, reduce the use of the tool cost.Therefore, cutter grinding reprocessing both save money and environmental protection has a high economic value and social value.
Product competition intensifying, the tool user puts forward cutting tool on cutting tool manufacturers stable performance, long service life, low price, fast delivery requirements;Cutting tool factory according to the different product structure and customer demand of tool grinding machine mainly has the following requirements:
Time is short, the operation is simple, and the machine can realize 3 d simulation software online processing, reduce the technical requirements of the operator, to reduce labor costs and improve labor efficiency;Product dimension precision, batch processing and high repeat precision, to adapt to the large-scale and high precision automation production requirements;Free programming, non-standard special tool for the development of complex structure, meet the special needs of customers;High grinding efficiency, short piece machining time, reduce the machine takes up time, reduce production cost, shorten delivery time;Form a complete set of equipment cheap, operation cost is low, reduce equipment accounted for the total cost of the cutting tool production scale;Low failure rate, avoid unnecessary abnormal downtime and maintenance.
