The CT 52 LR extends the company’s move into linear rail technology to its turning centres for the first time. Having proved successful on its machining centre range, where sales have “been beyond expectation”, the same level of interest in linear rail technology is being shown for the CT 52 LR. The advantage of using linear rails is primarily the cost, but without any compromise in capability, the company offers.
The CT 52 LR is available from under £36,000, but despite the relatively low cost, it boasts 15 hp/11.2 kW (4,500 rpm) spindle, 52 mm spindle bore, 10-station turret and Siemens 828D control with the PLC written by Siemens UK. It boasts a maximum turning length of 300 mm, swing over the carriage of 300 mm and a maximum turning diameter of 180 mm.
As standard, the CT 52 LR is equipped with a 150 mm three-jaw chuck, but there is an optional Hainbuch collet system and Hydrafeed, or LNS, bar feed units. All of this is built upon a 2,000 kg solid meehanite cast base that provides the rigidity required for “exceptional” machining performance.
As part of the Compact Turn family, the CT 52 LR lives up to its description, with a footprint of just 1,930 by 1,420 mm, making it ideal for the smallest of machine shops.
The larger XYZ CT 65 HD complements the existing Compact Turn. This larger model comes with enhanced turning capacity, now offering a 510 mm maximum turned length, almost double its predecessor, increasing it by 250 mm, and a total Z-axis travel of 525 mm. Another upgrade is increased coolant delivery pressure, which now runs at 30 l/min at 2.5 bar.
The HD designation relates to the CT 65 HD’s construction, which remains as a solid Meehanite ribbed casting, with X and Y axes positioned along hardened and ground box slideways. Positioning is by ballscrews that have been increased in size to 28 mm (X-axis) and 40 mm (Z-axis) respectively, with 20 m/min feedrates.
Metalcutting performance is boosted by using a Siemens 23 hp/17 kW, 4,500 rpm unit and the upgraded Siemens 828D ShopTurn touchscreen control. This is backed by a Sauter 12-position 30 VDI turret with through-tool coolant, along with the MT4 tailstock with 105 mm of quill travel. Other standard equipment includes a swarf conveyor, parts catcher, 200 mm diameter hydraulic chuck and a Renishaw Automatic Tool Setting Arm. The machine footprint is 2,950 by 2,030 mm.
Says Nigel Atherton, managing director at XYZ Machine Tools: “The arrival of these two additions to our turning centre range will provide us with a powerful turning centre portfolio, which we hope will see a better balance between turning centre and machining centre sales for XYZ Machine Tools. At present, machining centres outsell turning centres by around three to one, with these additions, we can see that becoming more in balance. We are already witnessing significant interest in the CT 52 LR with machines already delivered to customers.”
