Turn-mill centre prepped for automation

Building on the strengths of previous generations of Miyano fixed-head turn-mill centres, the BNA-42SY is Citizen Machinery’s latest addition to the range. The CNC lathe is the first BNA model to have a 12-station turret giving ±35 mm of Y-axis movement, all tool positions now being live, and a new design that lends itself to easy automation.

Compared with current BNA models, machining efficiency has been upgraded by more powerful spindle motors, which are rated at 7.5/5.5 kW (15min/cont) for the 6000 rpm main spindle and 5.5/3.7 kW for the 5000 rpm sub-spindle. Acceleration and deceleration are quicker on both spindles, improving productivity further by minimising idle times.

The machine’s rigid bed, the weight of which is now 1823 kg, brings thermal control advantages and more capacity to house a larger coolant tank. Notably, the base casting has been prepared with space at the right-hand side for robotic load/unload equipment. If a user intends to take advantage of automation, the machine is available with a swarf conveyor that exits to the rear as an option. Users may deploy the automation solely for unloading components that have been turn-milled from bar stock up to 42 mm diameter, either directly from a spindle or via a parts catcher and conveyor. Alternatively, or in addition, it may load and unload billets or near net shape workpieces like castings or forgings up to 135 mm in diameter.

Mounting points have been included to provide an option to add an overhead gantry if only chucking is to be carried out, in which case a raw material stocker can be positioned to the left of the machine in place of the bar magazine.

Workshop hits next level

Miniature Manufacturing, a machined parts specialist based in Sturminster Marshall, Dorset, has installed PSL Datatrack production control software to help the business ensure that it underpins component production with careful workshop scheduling, prompt delivery times and a commitment to full traceability. Owner Phill Wiles now acknowledges that running a workshop was much more difficult prior to having PSL Datatrack and, on reflection, wishes he had invested in the system earlier. “Once installation and training has been conducted by PSL Datatrack, payback on the investment starts pretty much immediately,” he says.

Compact turning cells with integrated robot

Japanese machine tool manufacturer Okuma has incorporated a robotic arm inside its CNC turning centres for the automated production of shaft- and chuck-type components. The sole UK and Ireland agent for Okuma is NCMT.

One of the first Okuma lathes to benefit from an internal ‘Armroid’ (Arm Robot Intelligent Design) workpiece load/unload system is the LB 3000 EX II, one of which is available for demonstration in NCMT’s Coventry showroom.

Three different end-of-arm effectors are available for performing different tasks. One is for blasting air or coolant within the cutting zone. This effector can be programmed to follow the cutting tool for breaking up stringy swarf or to clean down the whole working area, greatly improving chip management.

A roller end effector provides support under a shaft component during cutting to minimise chatter.

In combination with a workpiece stacker, the third end effector is a two-finger gripper for automatically holding shaft-type workpieces around their circumference for loading and unloading, with total weight capacity being 5 kg. All three end effectors are stored within the machine for automatic exchange by the robot.

It is possible to integrate a longer, more powerful Armroid into a second Okuma turning centre, a Multus B250II multi-tasking lathe. The robot arm handles workpieces up to 10 kg and possesses a fourth type of end effector with a three-jaw gripper for holding billets around their end faces.

Armroid systems are suitable for high mix, small batch work. The extended periods of unattended running release the operator to carry out duties in other parts of the factory. However, the cells are not for the lights-out production of large quantities of the same part due to the limited number of workpieces that the stocker can accommodate.

Manufacturing orders strongest on record

UK manufacturing’s total order books in November improved to their strongest on record (since 1977), according to the latest monthly CBI Industrial Trends Survey. The survey of 282 manufacturers also saw export order books at their strongest since March 2019. Output growth in the three months to November remained firm, increasing at a similarly above-average pace to October and September 2021. Manufacturers expect output growth to accelerate in the next three months. Meanwhile, expectations for output price growth in the coming quarter were at their strongest since May 1977.

ITC gives cutting edge to Game of Thrones

With almost 20 years in business and thousands of successful projects undertaken, Cutting Edge Designs specialises in routing, trade signage, acrylic fabrication, panelling, wood and laser cutting, printing, 3D carving, finishing, assembly, and CAD design. Since its inception, the Newry-based company has been working closely with the cutting tool experts at Industrial Tooling Corporation (ITC) to complete an extraordinary number of high-profile projects.

Founded by David Hogg, Cutting Edge Designs was set up in a small room at the back of his family’s furniture business with a single CNC routing machine. Now, the company can take credit for designing, machining and delivering unique projects for some of the most recognised brands in the world. When the first Tekcel routing machine arrived more than 15 years ago, the company turned to ITC, not only for its cutting tools, but also the company’s technical support and service.

Commenting upon the Northern Ireland company’s journey, Hogg recalls: “Prior to starting the business, I worked at a sign-making factory that was using ITC cutting tools, so I was already aware of the range of products and services available. When Cutting Edge Designs started up, we immediately turned to ITC for their expertise and extensive product ranges. The supplier of our routing machines provided alternate cutting tools when we began and, like other cutting tools that we have tried down the years, none have matched the performance of ITC.”

The company machines a vast array of materials that range from wood, veneer, MDF, plastics, metals, rubber, composite and much more. For every project and every material, Sally Hunt from ITC has been on-hand with technical support.

“During the early years of our business, Sally was fantastic at providing technical support with regard to what tools we should use on specific materials, as well as the speeds and feeds required to optimise machining performance and eliminate vibration,” says Hogg. “Over the years, our ever-increasing expertise relies less upon this technical input. While it’s always important to have technical expertise from our cutting tool supplier, nowadays the key factor is service and supply. From this perspective, ITC always has cutting tools in stock, supplied with next-day delivery. This service is absolutely first class, and it is why ITC are the best cutting tool supplier in the industry.”

Regarding some of the projects and brands the company has worked with, the list includes names like Ferrari, Guinness, M&S, Liverpool Football Club, Subway and KFC, through to famous artists and sculptors, as well as TV and movie companies. Two prestigious projects the company has worked on include the Game of Thrones television series and the Burning Temple for artist David Best – all machined with ITC cutting tools. In Derry, there has been an annual tradition for more than 40 years of burning bonfires – and in the process, protestants, catholics and the IRA would leave both their weapons and grievances outside, enter with respect and greet each other – ready to move on.

Working with show organisers Artichoke and David Best, Cutting Edge Designs was commissioned to cut 16 designs, each in a large quantity with over 1500 parts being cut from many of the 8 x 4 ft sheets of birch wood. Employing all three of its routing machines to the project and a variation of ITC cutting tools, Cutting Edge Designs estimates more than 400,000 cuts took place in the project’s three-month timeframe.

Unlike the Burning Temple that, like its name suggests, was burnt to the ground, the small business also worked with HBO Studios and Tourism Ireland in the creation of beech wood doors for the sixth series of Game of Thrones. Again, ITC was integral to the project. Produced from trees downed by Storm Gertrude in a location known as the Dark Hedges, Cutting Edge Designs produced 10 doors with each one incorporating designs, iconic symbols and references from the episodes. Receiving the artwork and 3D models, the subcontractor converted the files into CAM models and applied ITC single-flute routing tools and its Tekcel router to the task.

“We decided on using an ITC 12 mm diameter ball-nose tool for our initial rough cutting,” explains Hogg. “This removed the excess material, making it easier and more efficient for the smaller tools to do the finer details. A 90° wood-cut angle was also implemented to prevent lifting or splitting of the wood along the grain. The rough-cut cycle took about 6 hours per door. Following this, we utilised ITC’s 3 mm diameter ball-nose cutter to achieve all the important finer details, machining with a step-over rate of 0.2 to 0.3 mm. This fine detail work took an average of 50 hours per door to complete. When each door was finish-machined, it was sanded and professionally stained by one of Game of Thrones’ set painters.

For the majority of the machining, Cutting Edge Designs applied ITC’s 180 Series of solid-carbide tools, as their ability to prolong tool life, perform at higher speeds and feeds, and reduce cycle times is a huge benefit. For finish-machining, the company applied ITC’s 180-1181-10-A-XL single-flute cutting tool, a 3 mm diameter tool that is said to demonstrate exceptional tool life and rigidity. These attributes are credit to its reinforced 6 mm diameter shank, 10 mm length of cut and 30° helix geometry produced from an ultra-wear resistant micro-grain carbide.

Concluding on the relationship with ITC, Hogg says: “The ITC tools perform exceptionally well: we use everything from routers and engraving tools through to ball-nose cutters, drills, compression spirals and special tools. The range is extremely diverse, the quality is unbeatable, and the service is a cut above anything from any other tooling company. Regardless of the material we are cutting, ITC has a tool and a solution for our business.”
