Product Details Supplier Info More products

At Mach 2014, 1st Machine Tool Accessories will highlight chucks, rotary tables, vices and other accessories from Kitagawa. In addition, the company will showcase products from Iemca, Best, Abbott, Tecnomors, Chick and Darex. Mach 2014 is set to take place on 7–11 April at the NEC in Birmingham.

Mach 2014 marks the launch of the Kitagawa CK160 NC rotary table, which has a body measuring just 99mm deep. The ultra-compact fourth-axis is suited to mounting on the table of a BT30-taper machining centre and provides manufacturers with a larger machining envelope on any size of machine.

The thin profile also makes the NC table suitable for use with an opposing trunnion for securing and rotating a workpiece between centres in limited working areas. It may be orientated in the horizontal or vertical plane.

The CK160 is offered with a built-in rotary joint, in which case it is designated CKR160, both versions being 99mm deep. A conventional table would typically measure half as much again from the face plate to the back. The rotary joint, which has seven ports for pneumatic and hydraulic supplies (but not coolant), allows the unit to operate on the C axis or a four-axis machining centre.

Key features and specifications

Kitagawa CK160 NC rotary table

  • 114mm-diameter table
  • 65mm through-hole
  • 140mm centre height
  • 340Nm pneumatic clamping
  • 41.6rev/min maximum rotational speed
  • Indexing accuracy is 20 arc seconds, with four arc seconds repeatability
  • Workpieces up to 160kg may be supported with the table mounted horizontally, or 80kg if it is vertical

Kitagawa QJR quick-change power chucks

  • Interchangeable with the company’s large, through-hole B and BB series
  • With the QJR 08, 10 and 12 models, there is no longer a need for long-stroke cylinders or to accept a reduction in gripping force
  • The latest QJR 07 chuck has been added to the lower end of the range
  • The 07 chuck has a maximum gripping force of 60kN, a 53mm through-hole and can be run at up to 6,000rev/min
  • Manufactured from high-grade alloy steel
  • Units have base jaws that are rapidly and simply changed using a manually operated wrench
  • The units feature metric serrations to accommodate a variety of jaw types, including Kitagawa soft jaws
  • The chucks are suitable for small and large batch production

Kitagawa steady rests

  • For shaft machining on lathes and grinding machines
  • Range offers a high level of build quality to ensure accuracy and safety on the shop floor
  • Different versions encompass fixed or travelling positioning, vertical loading, crank shaft turning, models with an actuating cylinder, compact designs for restricted work areas and heavy duty models for components weighing up to 40 tonnes

Iemca Boss 21 bar magazine

  • Can be used with both sliding-head and fixed-head lathes
  • Compact model for feeding bar from 5mm to 51mm in diameter and with a maximum length of slightly more than 2m, making it suitable if a long bar feeder is required but space is restricted
  • Less material is lost through remnants than if shorter bar is used and longer periods of unattended running time are possible
  • Bar feed is actuated by an asynchronous motor and the position of the stock is encoder controlled
  • The remnant collector is at the rear of the magazine, together with the oil tank

Iemca Kid 80 short bar feeder

  • The Kid 80 is suitable for all types of single-spindle lathe, whether fixed or sliding head, CNC or cam-controlled
  • It can accept bar diameters from 5mm to 80mm and lengths from 90mm to a maximum of 1,615mm
  • Operation is entirely mechanical, without the need for a compressed air connection, assuring reliable performance and efficiency
  • Short bar feeders consume a minimum of space on the shop floor, typically half that of a full-length magazine
  • A further benefit of short bar feeders is that there is no gripper, so each remnant is small. It is pushed easily out of the front and ejected, avoiding the delay of extracting the remnant from the back of a full-length magazine and so maximising spindle uptime

Abbott master plate and segment system

  • Suitable for turning larger-diameter workpieces, the arrangement consists of an aluminium master plate, similar to a thin pie jaw, which is pre-drilled and keyed to accommodate Abbott’s standard, off-the-shelf segment rings
  • Plates are available in various diameters from 381mm to more than a metre and a half and can be mounted on different sizes of chuck, effectively increasing its holding capacity
  • The master plate can be custom machined to fit any model of chuck, making it a permanent, universal fixture on any machine
  • When using this system, the transition from one job to the next simply requires bolting on a new size or configuration of segments
  • For repeat jobs, machine operators can designate specific tooling, allowing them to set up in minutes using pre-machined segments from a previous run
  • Segments are available in specific ID/OD ranges, allowing time to be spent on making production parts instead of boring out excess jaw material
  • The master plate and segment arrangement maximises flexibility when moving work between production centres because segments can be used to run jobs on any machine that has been fitted with a master plate, regardless of machine or chuck type

Best zero-point self-centring vices

  • Exhibits from Best will include a mid-range RPC 140 vice with zero-point adaptation
  • By attaching a tightening bolt and two alignment bolts to the manufacturer’s BSM 140 vice, which is screwed conventionally to a machine table, the RPC variant as well as the encapsulated RPCG can be used as a zero-point vice on the Best Realpoint quick-change system
  • Other manufacturers’ zero-point clamping arrangements may be similarly used, after simple adaptation
  • The Realpoint zero-point clamping system is modular, so the vices, baseplates, pallets, quick-change jaws and tongue-and-groove jaws are rapidly interchangeable, increasing production flexibility and output
  • A single size of tightening bolt is applicable across the range of vice sizes
  • Advantages of RPC/G zero-point vices include high clamping force up to 50kN (100kN for BSM/G vices), 90° indexing of the pallet and vice, suitability for multi-axis metal-cutting applications on machining centres, and the ability to automate clamp actuation
  • Other notable qualities of the vices are the possibility to clamp on only 3mm of material, and ±0.01mm centring accuracy with five microns repeatability of centricity for manual and pneumatic vices, one-micron repeatability for hydraulic types
  • Jaw varieties including knife-edge options are manufactured from a range of materials from aluminium through machineable steel to hardened and ground steel to suit the application

Tecnomors component clamping and manipulation

  • The MD 205 automatic power chuck with hydraulic indexing and clamping has an outside diameter of 205mm, which allows a maximum rotational speed of 4,200rev/min
  • Manufactured from hardened bearing steel (60 HRc — UNI18NiCrMo5) to achieve a high degree of precision, reliability and repeatability, MD series chucks have a patented indexing movement, accurate to ± one minute of arc
  • It employs two preloaded roller bearings for radial movement and one axial bearing, sealed against contamination by coolant, chips or dust
  • The chuck is not self-centring but other automatic indexing chucks and manual chucks in the Tecnomors range are, making them suitable for multi-axis machining operations

Chick fast-acting workholding products

  • The System 5 series of dual-station Qwik-Lok, Multi-Lok and Pneu-Dex units enable rapid and fewer changeovers on machining centres to maximise productivity
  • Pairs of parts can be secured simultaneously in two sets of quick-change, snap-on/snap-off jaws by tightening a single handle, immediately doubling productivity
  • Machineable soft jaws allow multiple parts to be clamped at each station, boosting output further
  • Up to five units can be fixed to the table of a standard vertical machining centre or up to six to a fourth-axis indexer or tombstone on a horizontal machining centre, resulting in considerable reductions in set-ups, tool changes and floor-to-floor times
  • The One-Lok clamping system provides the speed, precision and flexibility demanded by modern CNC machining operations
  • It eliminates the shortcomings of standard knee mill vices, which require up to 70 complete revolutions of their operating handle to be fully opened or closed
  • One-Lok features a Qwikslide mechanism that allows the moveable jaw to be easily unlocked and slid forwards or backwards to achieve rapid set-ups
  • Its maximum gripping capacity of 17in (432mm) is complemented by the manufacturer’s Boltfast jaw system, which enables jaws to be replaced quickly and efficiently with a repeatability of 0.0008in (0.02mm)
  • The system’s compact, modular design also features squeeze clamping, which imparts a pull-down action and virtually deflection-free clamping with a maximum retaining force of 4.5 tonnes

Darex CNC sharpener

  • The XPS-16 four-axis CNC drill sharpener will be demonstrated restoring high-performance drills in a simple, one-touch operation
  • The bench-top unit costs the equivalent of 100 radial split-point carbide drills, yet even unskilled operators can sharpen more than 400 of them in a day
  • Return on investment is typically less than eight months
  • Conical, four-facet, split-point and radius split point twist drills with angles from 90° to 150° can be processed, including high-speed steel, cobalt, solid carbide and coated tools from 51mm to 254mm (2in to 10in) long and 3mm to 16mm (1/8 to 5/8in) diameter
  • A blunt drill is inserted into the mains-powered sharpener’s chuck and the required standard or custom type of drill point is selected using a simple LCD touchscreen panel
  • The unit then sharpens the drill and applies the required split point form in one seamless operation, without operator involvement
  • The sharpener incorporates long-lasting super-abrasive plated grinding wheels, 180 grit cubic boron nitride for HSS drills and 220 grit diamond for carbide tools
