New CNC Machineries from ECVV Become A Daring Challenge to Its Competitors

SHENZHEN, China – March 26, 2014: A cluster of new CNC machines has been introduced by ECVV which are poised as a direct challenge to other major B2B online portal. The new CNC Milling Machine and CNC Router Machine displayed on the catalogues expected to infuse fresh waves in the online marketing business and increase the competition.
Machineries play vital role in the overall development of countries in the growing sector. Gone are the days, companies depends on few suppliers. Ever since the arrival of ECVV in the B2B market and their introduction of CNC machines have changed market perspective. Today ECVV enjoys an enviable position in the online business other than its cotemporary competitors. They have consolidated their presence further by adding new products of CNC machineries especially CNC Milling Machine and CNC router with easy terms of supply. From the vast pool of 334 milling machines and 2,681 models of router machines, selection of machines became a convenient option with few mouse clicks.
With the introduction of cutting edge technology incorporated CNC machineries, the sales of CNC Router Machinery re-gained the lost momentum of sales that has been badly affected by the world economic recession. Mr. Steven Chen, the CEO of ECVV put the facts in an overwhelming enthusiasm that “China is expected to rebound in the machineries export market with a projected growth of 6.8% per years. This projected growth is much more than any other industrially developing countries. The new favorable trend shall continue for few years and we have the price flexibility in China’s advantage”. He further said, “We have streamlined our marketing efforts by adding more CNC milling machines and CNC routing machines in our portfolio, which are economically priced with quality assurance. To boost the confidence of our clients we have introduced lot of support service, after sales service with the strong backup of our principles”. There are some unique features which are special with ECVV such as product guarantee and replacement or free repair or free service during the warranty and guarantee period. It is could be seen as a bold initiative by ECVV and that marks the differenceof comparing the relatively new incumbent with veterans of this field.
ECVV has a strong presence in machinery portfolio
Buyers would be bemused to see the machinery portfolio of ECVV. Well laid details along with product pictures, technical specification and make of the product gives an ample positive feel of the product. The brand name of the product let the buyers to do a market survey and reach in to a conclusion with justifiable reasoning. It would be a tough experience in going through all the product details. But ECVV has special key word options which allow the customer to search for the exact machine what they are looking for. With these options, clients will be getting few short listed machinery details that would help them to narrow down the selection.State of the art net software is used to give quick computing with lightening speed and accuracy. The site optimized well to meet the customers challenging demands. The overall business environment with ECVV is turned out be a pleasant engagement.
The impact of recession on machinery sales with a global perspective
The world economic recession played an important role in slow down the pace of rapid growth of Chinese machinery tool industry. By 2012 CNC cutting machine touched a whooping growth of 25.8% and CNC forming machine had a growth of 5.8%. This is considered as an exploding growth when compared with world machinery growth and sales. Presently the machinery Chinese industry had a considerable sales drop and the 2013 statistics had shown the growth rate as 5.5 percentage. This is in fact a healthy situation comparing to the other contemporary competition from developing countries. The efforts of ECVV to trap the desperate importers who are looking for cheap and reliable CNC machineries have shown promising results.

CNC Tool Grinding Software handles complex geometries.

NUMROTO v3.8, run on Flexium+ CNC system, automates multi-helical and variable flute grinding and provides form cutter function for profile inserts. Utilizing speed and computational capabilities of PCs, software can handle complex path calculations necessary to create sophisticated flutes. This aids users in accurately defining core path geometry of flutes on end mills. Software also supports 3D models for production clamping system, which enables visualization during 3D simulation. 

Complex-Geometry Machine Tool Manufacture and Service Simplified by New CNC Tool Grinding Software


Naperville, IL --- The growing challenges of grinding and servicing new generations of complex-geometry drills and end mills are resolved by a new release of the NUMROTO tool grinding software package. Version 3.8 of NUM's market-leading software automates multi-helical and variable flute grinding, as well as providing a new form cutter function for profile inserts. It is available to existing NUMROTO users as an update.

NUMROTO is widely regarded within the tool grinding industry as one of the best and most versatile CNC software solutions on the market. Launched by NUM in 1987, it has undergone continuous development to stay ahead of improvements and innovations in machine tool design. The software runs on NUM’s powerful Flexium+ CNC system, which offers significant advantages. These include the use of sub-nano interpolation to ensure high quality surfaces, with short cycle times to allow fast 5-axis movement – even if the part program contains a very high density of ISO sequences. Flexium+ supports all the safety functions that are needed on today’s high performance machines and can be operated very easily, using the same type of ‘dual touch’ gestures that are employed with modern smartphones.

Today, 15 of the world’s leading manufacturers of CNC tool grinding machines incorporate NUMROTO software in their products, to the extent that it is used across more than 40 different types of machine.

Many of the high performance end mills that manufacturers now employ for precision machining applications, such as the production of aircraft components from specialist alloys or composite materials, are multi-helix tools designed for use at speeds up to 30,000 RPM. Producing these types of tools cost-effectively is a demanding process that requires increasingly complex grinding capabilities. For example, to help prevent vibration, each of the tool’s cutting edges is twisted at a different angle – and with differential helix designs, the twist angle of each individual cutting edge also changes along the length of its body, from the tip of the tool to the shaft. Furthermore, the width of the flute area of these tools can vary considerably, demanding precise positioning of the grinding wheel to ensure that the land width on the back of the tooth is correct.

By harnessing the speed and computational capabilities of modern PCs, the latest version of NUMROTO software is able to handle the extremely complex path calculations necessary to create these sophisticated flutes. Users can now define the core path geometry of flutes on end mills very easily and accurately.

Designers and manufacturers often seek this functionality when optimising the chip transport characteristics of high performance machine tools – the rate at which chips are removed from the cutting face has a major bearing on the tool’s cutting speed and efficiency.

By allowing the core path of each flute to be defined individually, NUMROTO also makes it possible for tool designers to compensate for any potential imbalance caused by irregular helices or asymmetric cutting blades. Additionally, by enabling the entry point of the grinding wheel to follow the corner radius of the cutting edge, the software now facilitates the grinding of a defined rake angle on complex body forms and on cutting edges which pass from the body of the tool to its tip – a task that was previously extremely difficult to achieve.

NUM believes that the level of control flexibility now provided by NUMROTO software for creating flutes will prove to be a key enabling factor for manufacturers seeking to develop the next generations of machine tools.

Nowadays, the cutting edges of most machine tools are ground from tungsten carbide. Small rotary tools are usually manufactured from a single piece of carbide, whereas larger rotary tools and the majority of non-rotary tools feature individual cutting blades in the form of carbide inserts, which are retained in a holder made from a less expensive material. Until relatively recently, the inserts were soldered or cemented to the holder prior to being ground, which sometimes made it very difficult or impossible to produce or maintain such tools on a CNC tool grinding machine – due to their size and complexity. Another disadvantage of this approach is that it requires the manufacturer to define the complete assembly as a rotary tool in the CNC program, demanding time-consuming and expensive programming.

Working in partnership with a number of leading machine tool manufacturers and tool sharpening companies, NUM has further developed NUMROTO's form cutter function to simplify insert grinding significantly. Users can now define a form cutter as a rotary tool or as a standalone profile insert. Holders with soldered or cemented inserts can still be defined as rotary tools, and the position of each insert can be probed individually, allowing any mounting inaccuracies to be detected and compensated for automatically during the grinding process.

Many of the latest cutting tools employ user-replaceable profile inserts, which are ground as physically separate blades on a CNC grinding machine. Instead of being fixed to a holder during grinding, the insert is held in a production clamping system that has an optimized geometry for efficient grinding, with unobstructed working space for the grinding wheel.

NUMROTO’s new profile insert function simplifies the programming of the new types of ultra high efficiency CNC tool grinding machines that are now coming into service. After selecting the profile insert form cutter, users are presented with an easy-to-understand menu that enables them to specify whether the part to be ground is held in a fixed or adjustable collet, or by clamping plates. The software supports different mounting plate arrangements to allow the insert to be oriented in any of three planes and provides a simple means of specifying parameters such as transverse and longitudinal offset values. NUMROTO also now supports 3-D models for the production clamping system, which enables it to be visualized during 3-D simulation and monitored for collisions with the grinding wheel; the insert itself is displayed as a cube-shaped blank. www.numroto.com

CNC machine suppliers underscore accuracy, safety

The latest releases adopt ball screws and linear slide guiding rails, and have emergency shut-off switches.


    CNC machine
    TOP TRENDS
  • Stepper motors lead: Most suppliers employ such mechanisms because they are less costly and widely available. The presence of 50 to 100 magnetic poles also makes stepper motors easier to control. Topping 2,000rpm, however, these are not suitable for high-speed production. Servo types, meanwhile, are capable of 80 to 90 percent accuracy at rapid rates but require a position encoder. These are often sourced from Japan and used in upscale machines.
  • Increased precision: For drive screws, companies are adopting ball types as the components are suited for fast-paced operation and withstand heavy load. Makers are also incorporating linear slide guiding rails from Japan's THK and Taiwan’s AMT, which have high speed, accuracy and movement sensitivity, and low resistance.
  • Safety features: Most CNC machines are equipped with an emergency shut-off switch in case of a malfunction. Some units may have more than one. Several also feature pressure mats that halt operation automatically when a person comes too close to the machine. Dust- and sound-resistant enclosures to block flying debris are common as well.

VERICUT is at the heart of the CNC manufacturing process

At MACH 2014 the latest version of VERICUT, V7.3, will be featured on CGTech’s stand 4021, Hall 4. VERICUT CNC machine simulation, verification and optimisation software simulates all types of CNC machining, including drilling and trimming of composite parts, water jet, riveting, robots, mill/turn and parallel kinematic/hexapods. It operates independently, but can also be integrated with leading CAM systems. 


A common feature of all recent releases of the software has been the focus on full integration with the CAD/CAM and machine tool industry. As a result VERICUT is now at the heart of the  CNC manufacturing process for many of the world’s leading engineering businesses in all industry sectors, including aerospace and defence, oil and gas, power generation, petrochemical and fluid processing, motorsport, automotive and transport, medical device and implant, as well as general precision and heavy engineering.
Machine simulation with VERICUT detects collisions and near-misses between all machine tool components such as axis slides, heads, turrets, rotary tables, spindles, tool changers, fixtures, workpieces, cutting tools, and other user-defined objects. Setting up ‘near-miss zones’ around the components to check for close calls, and detect over-travel errors. Machine movements can even be simulated while stepping or playing backwards in VERlCUT‘s Review Mode.
With VERICUT Reviewer shopfloor personnel, suppliers, customers, and other production engineers can view animations of the CNC machining process. It is a stand-alone viewer that does not use a license that can play forward and backward while removing and replacing material. New for MACH, the Reviewer files will also be able to operate on an iPad.
Integration with CAM CNC Programming
As an independent system, VERICUT can run standalone and simulate the CNC process driven by post-processed NC code. However, in practice, most manufacturing companies use a CAM system to create CNC part programs. VERICUT can be integrated with all leading CAM systems including Dassault Systemes CATIA, Siemens PLM NX, Delcam PowerMill and FeatureCAM, Vero EdgeCAM, DP Technologies Esprit, CNC Software MasterCAM and Open Mind HyperMill.
The verification provided by VERICUT enables users to view and analyse the geometry of the cut part. Models can be cross-sectioned multiple times at any orientation, to check areas that would be impossible to see in a solid model (such as the intersection of drilled holes).
Integration with cutting tool suppliers and Tool Management Systems
As with all software programs the accuracy of the data input will directly affect the output. So, an accurate model of the cutting tool and holder is required for the effective and accurate simulation of the machining process. Leading cutting tool manufacturers, such as Sandvik, Kennametal and Iscar, now make 3D solid model data available to users and VERICUT has tools to read in this model data for use in the simulation process. VERICUT also interfaces with tool management systems such as TDM Systems and WinTool for access to databases holding cutting tool information. Pre-setting suppliers including Zoller and Speroni can also interface to the software, so tool offsets and exact dimensions can be applied to the simulation process.
Simulation of all types and machine tool brands
CGTech has worked with end users and machine tool manufacturers and distributors to create accurate and effective Virtual Machine Tool configurations. These range from simple 3-axis milling machines to multi-axis machining centres; simple 2-axis lathes to complex mill-turn centres with sub-spindles and robot loading; water jet and laser cutting, and machining/polishing robots.
VERICUT simulates every machine tool brand, including DMG Mori-Seiki, MAZAK, Makino, Matsuura, Hermle, Chiron, Starrag, DS Technologies, WFL, Nakamura-Tome and more.
Other Products
With the growth of the various additive manufacturing processes CGTech has developed programming and simulation of the CNC processes used in this technology area, including automated composites fibre placement and tape laying.
The automated drilling and fastening machines used for the production of aero-structure components are also supported by VERICUT Drilling & Fastening (VDAF). It allows the user to visualise and simulate CNC drilling and fastening machines using the same NC program code that will be run on the machine. Simulation is independent of programming, and VDAF can simulate NC programs from any programming system for any CNC-automated drilling and fastening machine.
With the modular format of VERICUT the software provides flexibility, so companies purchase only the capabilities they need. It is easy to add modules as required as CGTech provides a license that gives immediate access. VERICUT runs on Windows platforms and is delivered as both a 32-bit and 64-bit application. G-codes and CAM centre-line (CL) formats are supported.
