Motorized Notch Cutter (Variable Speed)
Motorized Notch Cutter (Variable Speed) (Product Code: SLE/ET/04) is a specimen-preparation machine used to cut a precise notch into test bars before pendulum impact testing in plastics and materials laboratories. Its 45° cutter is driven by a 1440 rpm motor through a vector-controlled variable speed drive, its 0–25 mm range reads to 0.01 mm, and an acrylic safety jacket guards the cutting area. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory equipment supplier in India for materials testing rooms.

What Is the Notch Cutter Used For?
Impact results can only be compared when every specimen carries the same notch, and hand-filed notches rarely match. This machine cuts the notch with a motor-driven 45° cutter, and its 0–25 mm range is read to a least count of 0.01 mm, so each bar in a batch can be given the same setting.
The vector-controlled drive lets the operator lower the cutting speed for heat-sensitive thermoplastics, which can smear or melt at the notch root if cut too fast, and raise it for tougher materials. Clamp each bar firmly, keep the acrylic jacket closed while the motor runs, clear chips between cuts and inspect the notch before the specimen goes to the impact tester. It is a sensible addition to engineering lab equipment in India wherever Izod or similar impact tests are taught.
What to Specify When Ordering
- Confirmation that the 45° cutting angle matches the notch your test method calls for
- Your specimen sizes, so fit within the 0–25 mm range can be checked with us
- Site supply (listed: 230 V, 50 Hz, single phase)
- Whether an impact tester should be quoted with it
- Quantity and delivery location
Supplier
ScienceLab, the trading name of Jain Scientific Equipments Private Limited in Ambala, Haryana, supplies this notch cutter mainly as part of impact-testing set-ups for plastics laboratories, engineering colleges and polytechnics in India and international markets.
Because a cutter wears with use, ask us about replacement cutters when you send your enquiry. Company details are on the ScienceLab profile.

Instruments that use or complement notched and moulded test specimens:
- Computerised Izod Impact Tester — breaks the notched bars and reports impact strength.
- Impact Testing Machine-Digital — an alternative impact tester that also works with notched specimens.
- Computerised Tensile Tester — for tensile specimens cut from the same material.
- Computerised VSP & HDT Apparatus — thermal softening and deflection tests on the same polymer.

Frequently Asked Questions
What notch angle does the Motorized Notch Cutter (Variable Speed) cut?
The Motorized Notch Cutter (Variable Speed) has a 45° cutting angle. Check that this matches the notch specified in your impact test method before ordering, and tell us if your laboratory works to a different notch profile.
What range and least count does the notch cutter offer?
The Motorized Notch Cutter (Variable Speed) has a range of 0–25 mm read with a least count of 0.01 mm, allowing fine, repeatable settings from one specimen to the next when a batch of impact test bars is prepared.
Why does a notch cutter need variable speed?
Variable speed lets the Motorized Notch Cutter (Variable Speed) match cutting speed to the material. Its vector-controlled drive adjusts the speed of the motorised cutter, so it can be reduced for heat-sensitive plastics that might smear or melt and increased for tougher materials.
What safety features does the Motorized Notch Cutter have?
The Motorized Notch Cutter (Variable Speed) has an acrylic safety jacket around the cutting area. Keep the jacket in place while the motor runs, and switch off the 230 V supply before clearing chips or changing specimens.
Who supplies the Motorized Notch Cutter (Variable Speed)?
The Motorized Notch Cutter (Variable Speed) is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, to plastics testing laboratories and engineering institutions in India and international markets.
What should a quotation request include?
For a Motorized Notch Cutter (Variable Speed) quotation, state the quantity, delivery location, specimen sizes and the notch your method requires, and whether an impact tester should be quoted too. Use the contact page or the enquiry cart.
Request a Quote
Send your notch cutter requirements through the contact page, or add the machine to the enquiry cart together with your impact tester, and ScienceLab will reply with pricing and delivery terms.
