Special Purpose Machine

SPECIAL PURPOSE MACHINE OR SPECIALLY DESIGNED MACHINE

SPMs offer tremendous scope for high volume production at low investment and at low cost of production when compared to CNC machines. SPM is a high productivity machine, with specially designed tooling and fixture, dedicated for mass producing the same component day in and day out. A judicious combination of limit switches, sensors, logic controls, automatic job clamping etc is the essence of a SPM. A well conceived SPM finds ways and means to utilise the man and machine to the optimum. We offer low cost dedicated SPMs for mass production of small components of 2 & 4 wheelers, tractors, trucks, engines etc. Typical components are rear wheel flange, shifter cam, shifter fork, clutch sleeve etc. OUR SPMs ARE SUITABLE FOR MASS PRODUCTION OF COMPONENTS WHICH INVOLVE OPERATIONS LIKE TURNING, BORING, FACING, DRILLING, REAMING, TAPING, CHAMFERING ETC. These machines work with 4 to 8 stations, depending upon job requirements. Most of the machine concept is standardized which enables very fast delivery of the machine.

MULTI SPINDLE, HIGH SPEED MILLING MACHINE

Multi Head Milling SPM

  • 4 spindle units – two vertical & 2 horizontal
  • Hydraulically operated 4 slide units for linear movement
  • Hydraulically operated automatic job clamping system
  • Auto-cycle through of limit switches & PLC
  • Ideal for mass production

Duplex Milling Machine

Duplex Milling Machine

We offer custom-built Duplex Milling Machines to end face multiple components, both from the front and from the back simultaneously. Hydraulically operated automatic clamping system, with a well designed job holding fixture, facilitates multiple components to get clamped simultaneously and quickly. Two milling heads, one in the front and the other in the back, simultaneously perform end facing operations on both the faces of all the mounted components simultaneously in one rapid go. Job clamping, rapid approach of the spindle, machining, rapid homing, rapid de-clamping etc will the part of an efficient auto-cycle, delivered by the combination of limit switches and PLC. The total cycle time for duplex end facing the multiple components, is a few seconds. The machine is designed for high productivity at low cost, consistent accuracy and with least dependency on the operator’s skill.

SEPL’s milling heads are already well known for reliability and ruggedness in thousands of Plano milling conversions all over India and abroad. Matched pair angular contact bearings, used for supporting the spindles of unit heads of milling SPMs, ensure a very high level of spindle accuracy and high spindle speeds.

Combination of turcite and case-hardened guideways for high wear resistance and smooth liner movement, automatic lubrication system, efficient coolant and chip disposal system, machine enclosure, easily accessible machine controls etc are the features of the Duplex Milling Machines. Automatic chip disposal system is offered optioally.

Multi Station Pendulum Milling SPM

Multi Station Pendulum Milling SPM

This multi station pendulum type of milling SPM is another effort by us to utilize the man and the machine to the optimum. What otherwise would have been possible for at least 2 SPMs (each SPM with 2 spindle units) and two different operators, is made possible by this single Pendulum Milling SPM in terms of productivity. The Pendulum SPM consists of totally 3 spindle units and two job holding fixtures at LH & RH stations. When the machining is going on at both the ends of the same component simultaneously in LH station, another job is being loaded in the RH station. This SPM has a capacity of producing 150 finished components per hour. For this kind of output, 3 machining centers would have been needed, which means the additional space, power & operator for 2 more machines.

 

Side Frame Milling SPM

Side Frame Milling SPM

This is a Side Frame Milling SPM. The SPM has totally 9 axes and 3 spindle units, thus providing a unique capability to machine the different segments of the same component simultaneously in the same setting. It avoids machining the same component in multiple setting and considerably saves on time and boosts productivity and accuracy.

Knurling SPM

KNURLING SPM

A spinning kurnling wheel, when pressed on a component, produces knurls.
Knurled OD adds to the grip on a cylindrical male OD of a component when a female cylindrical component tries to grip it. Handle bars in a two wheeler or bicycle is the ideal example for this application. Instead of conventinal lathes, dedicated SPMs for knurling helps mass produciton of knurled components in thousands.

Special Purpose Machine for Knurling

Knurled OD adds to the grip on a cylindrical male OD of a component when a female cylindrical component tries to grip it. Handle bars in a two wheeler or bicycle is the ideal example for this application. Instead of conventional lathes, dedicated SPMs for knurling helps mass production of knurled 2 wheeler handle bars and other components in thousands.

  • Two HSS knurling wheels mounted on hydraulically operated slide units
  • A well designed job holding fixture with quick clamping and de-clamping mechanism through clamping cylinders
  • Hardened and ground male guideway strips; Turcite linings for female sliding surfaces; Wipers for guideway protection
  • Metallic, collapsible guideway covers
  • A well designed coolant and chip disposal system (without a chip conveyor)
  • Automatic lubrication system
  • PLC based auto-cycle for automatic clamping of job, knurling operation and de-clamping of job
  • A compatible & operator-friendly electrical panel and console which will be easy and simple to maintain – complete with all required interlocking logics and safety features.
